The 100-Mile Week: Should You Try It?

Training for a marathon requires more time and effort than most think. It is not all about just running. Getting your body to be able to reach 26.2 miles safely and injury-free requires several other components. The priority should be to make sure we can get to that 26.2-mile mark without getting injured, burnt out, or being zombie-like throughout the entire process. Besides running several days per week, training will require extra time for strengthening sessions, stretching and more sleep. Because of this, there are a variety of different training plans you may find that are a “minimalist” approach, which include the least amount of mileage per week that will get you ready for race day.

On the opposite spectrum, there are those hard-core marathoners who have been training for years and attempt those very high mileage weeks without a problem. The most difficult part of this type of high volume training is the amount of time it requires. If you have a regular work schedule and a family to tend to, the hours remaining in your day will just be for training and sleeping. Evidently, you must be okay with the sacrifice. For the regular person, a normal training plan will usually consist of 50 to 60 miles per week at the most, whereas high mileage would be considered 75+ miles. Scattered throughout the week with some days including a morning and evening run, it can definitely be doable.

What about the elite runners out there hitting 130 miles per week? It sounds crazy but there is a science behind this extraordinary mileage. The classic 100-mile week is something even the everyday hard-core marathoners try to achieve. Some may say it is completely unnecessary, and that may be so, but if research shows a benefit to getting you to that next level, it may be worth a try. Fifty miles per week probably feels hard enough when first starting out, so considering doubling up your training will most definitely seem impossible. The key to getting to this point is to gradually and safely increase the workload. And no, this training approach isn’t for everyone OR the only way to progress in distance running.

Why 100?

Running Economy

Well, training to hit a weekly mileage of specifically “100” miles is merely just to get to the triple digits, because in essence 95 miles will provide the same benefit. Several studies have been done on high volume training and have concluded that there are many benefits linked to improving running economy. Basically, this means the more miles you run the less your body will have to work during the race, allowing you put that extra energy into faster paces. This is due to muscle and tendons training to adapt to prolonged running. These adaptations lead to increased elasticity of joints including the ankle, which in turn leads to a more forceful and less vertical push-off from the ground with each step. This will save a good amount of energy over time.

Aerobic Endurance

The goal of marathon training is to get our bodies to be able to run far, and if possible, fast.. The higher mileage programs essentially increase the amount of mitochondria and capillary density in the body, as well as hemoglobin and red blood cells. The growth of these factors leads to more and better oxygen transport through the blood cells to the muscles. This is why marathoners are eventually able to run farther and faster over time. Once you train to run more miles your body will learn to use fat as fuel and store more glycogen, which means more energy will be readily available for when you really need it, like at the end of a race.

Resistance to Fatigue

When you go from running 50 or 60 miles per week to 100 miles per week, the majority of those extra miles should all be performed at a slow, easy pace. The lower intensity, high mileage prepares not only our bodies for long races but also our minds. When you ask someone who is not a runner how they feel about running 26.2 miles, they will most likely think it’s a crazy idea. That’s because our minds become just as fatigued at the thought of running for so long as our bodies do. Many of the training runs in a 100-mile program will be 10-15 mile easy runs, where your body will undergo uncomfortable fatigue and soreness at times. It is during these long, slow runs that we get our mind accustomed to this sensation so that come race day, we can push through it.

Should I Try It?

Training to reach a weekly target of 100 miles is definitely not easy, but it is doable. The difficult part besides the extra time and sacrifice it will require is the high risk of injury it brings. More time on your feet means more chances of both accidental injuries as well as overuse-type injuries. It is important to gradually increase mileage every week. This means setting enough weeks in your training cycle to build up to 100 miles with no more than 5-10% increases per week and low mileage weeks built in every few weeks. The most important rule is to listen to your body not only for signs of pain but also for symptoms of overtraining and fatigue as well. Along with the 100 miles should also be at least 7 to 9 hours of sleep each night and 2 to 3 days of strengthening exercises. If these components are possible with your schedule then incorporating this extraordinary mileage program can be attainable.

Recovery: The Key to Improvement

I am sure the majority of distance runners have read a ton of articles about how important recovery is when trying to improve performance. Well, unfortunately many runners learn the hard way when they get injured about how sticking to a recovery routine is absolutely necessary if you want to keep running for a LONG time. I usually say my routine is pretty basic, but in reality, it is actually NOT basic at all. I find myself adding in so many components whenever I do my own research, follow someone who is including some random tactic I have never thought of, or simply when I find myself more tired than usual and realize I need to take a step back. Here are my go-to components I include on a regular basis to keep me injury free and ready for my next workout.

·     Diet: For recovery, the focus is usually on that very important post-workout meal; and while that is definitely essential, I believe your diet in general plays a significant role. I got into macro counting a while back and found it to be the best way to eat as an athlete, since it focused on the right mix of carbs, protein, and fats. It was a bit too time-consuming for me, so I no longer count my macros every day, but I do make sure I eat all three (carbs, protein, and fat) in EVERY MEAL. From the protein bars I buy to my restaurant choices, I am conscious about including each macro. This is how I stay satisfied all day! Each of these nutrients play different roles in recovery (more on this in another post), so making sure to be properly fueled with each is vital! 

·     Sleep & regular “down-time”: While I am definitely not the best sleeper (I am lucky if I can ever reach 7 hours of sleep any night), I do my best to avoid any stressors at night and get to bed early. I also incorporate “down-time” during most of my days where my legs can rest. Getting enough sleep is more important for those of you who have physical jobs that require you to be on your feet all day. Thankfully I work from home for the most part and get enough time to relax…BUT too much of this is not good either! There are days I end up sitting, working on the computer for hours without standing and it actually makes my next day’s run much harder than if I were on my feet all day!

·     Compression: Ever since I won my Normatec Recovery System on a social media giveaway, I have been a true fan! I did some research on the benefits of compression for recovery and learned how valuable this can be for athletes. The outcomes are different for everyone I assume, but since using my boots most days of the week, my legs feel much looser in general, I never get my plantar fasciitis pain (and this was a big issue for me!), and my evening runs are much more tolerable. 

·     Supplements: Although there is no scientific proof that many supplements out there actually work, I have a handful of products I believe have helped me recover faster and feel healthier overall. I take glutamine after every run. This amino acid is usually decreased in the body after any physical or emotional stress (think high intensity workouts, illness, etc.), and plays a role in immune function. Many endurance athletes are more susceptible to catching a cold, and I do not want to deal with one (who has time for that?!), so I do what I can to keep my immune system strong. I also add beetroot powder to my smoothies most days, since it is known to help with stamina and endurance, but it also has loads of antioxidants and other vitamins and minerals that are healthy for the body. Cherry juice has also been a staple in my diet—either in my smoothies or alone at some point during the day. Tart cherries have anti-inflammatory properties, which help reduce soreness and other pain. They are also a natural source of melatonin, which aids in improved sleep quality.

These habits took a while for me to stay consistent with (I am still working on the sleep one!). Besides these components, I also get a massage every few weeks and stretch every day. I have spent a good amount of time on researching about recovery for myself and my clients, so I’ve incorporated more into my routine over the years. My best advice for my athletes is to always listen to your body. Running and training for distance races should not make you exhausted. If it does, then you are definitely missing a component to your recovery routine. Take a step back, switch out running for another easy cross-training activity, and get some rest. It is always best to take a few days off than to deal with an injury.

Tackling PRs and Stress During the Holidays

No matter what difficulty this year has brought, the wintertime can still be enjoyable and end on a productive note. The change in lifestyle we’ve all had to deal with during 2020 has sure brought about an immense amount of stress for everyone. The change to a work-from-home situation seemed like a less stressful option, but in reality most of us loss a sense of structure to our days. It also has not been easy dealing with having to be socially distant from our families and friends, but hopefully knowing we are doing this for the good of their health makes it a bit of an easier choice.

Will We Ever Race Again?

That has been the question of the year for runners! It went from having our big spring races canceled to basically being without in-person races the entire year. It looks like the beginning of 2021 won’t be any different, so the near future planning of running goals is making most of us unmotivated to get in our training runs every day. During this season of the year, it will be most important to work on mental strength more than anything. It will take effort, but trying to put aside all of the stressors that we cannot control, is the key to getting back into the rhythm of taking care of our bodies. After all, exercise plays a pretty big role in stress management and immunity—a big focus with the current viral pandemic.

Since I’ve had a very long base building phase this year, I had a vision of using it to improve my endurance and work on weaknesses. Six months passed and I realized the anxiety of the life changes made me less focused on these goals. One of the most unwanted side effects of stress is lack of energy, and it was what was affecting me the most. Thankfully I turned to MitoQ and I’ve not only had optimal energy all day, but after taking a good amount of time off recently, my fitness has returned much quicker than ever before! I’m sleeping better and feel I can focus much more on my work without a problem.

MitoQ is a powerful antioxidant that works to limit the damage in our cells’ mitochondria—the powerhouse of the cells, and keeps them fired up for any activity. By doing this, it helps improve our stress levels, energy, sleep quality, digestion, immunity and reduce recovery times after hard workouts, since these are all jobs of the mitochondria. All it takes is two capsules in the morning before eating and you’ve got a productive day ahead of you!

Tips for Getting and Staying Healthy

Below are just a few of my go-to tactics when trying to remain focused and motivated to tackle my running and work goals. 

• Move every day for at least 20 minutes.

• Eat the rainbow! Keep a diet that has foods from every food group as many days as you can. But don’t deprive yourself—eating what we like every once in a while can be a stress-reliever!

• Incorporate supplements in your diet where you need them, and make sure they are supplements that have been clinically studied, such as MitoQ.

• Prioritize sleep and stress management: set aside time every day for yourself—to read, soak in the tub, or do some yoga.

• Don’t let what’s going on around you make you anxious—control what you can control and let the rest be!

Periodization Training is Smarter Training

When researching for marathon training plans, you have probably come across the term “periodization”. Basically, the idea behind this training approach is breaking up a training cycle into blocks of about four to eight weeks in length that serve different purposes. It is tough to work on achieving all goals to be marathon-ready all at once, so periodization training has a focus on working on one or two goals at a time. This is most definitely a more realistic training plan for someone who either has limited time to begin with or has several months before their next race. Even elite and professional runners train this way year round. It not only keeps us sane and less stressed working on one thing at a time but also decreases the risk of injuries and burnout.

Periodization Phases

Base

The first phase of periodization training focuses on building endurance, which is the foundation of any long distance running. This is the phase that builds up mileage using gradually increasing easy runs with only a few short speedier runs mixed throughout. The speed work during the base phase should include of 10 to 20 sets of 20 to 30-second strides at the end of a few easy runs each week. Strides are useful for working on proper running form and to prepare the body for faster running. Each set should be a gradual pick-up in speed to a controlled fast pace while working on increasing your stride length. Performing strides on grass decreases the impact on the body.

Another addition of speed work during the second half of the base phase is the inclusion of mini tempo runs. Pick one easy run per week to include 15 minutes of running at around half marathon pace. This will begin introducing faster paced running so that the next phase of your training cycle will not be too shocking. Weekly long runs are the cornerstone of phase one and should always be done at conversational pace and build up to about 15 to 16 miles in length. Two to three days per week of weight training should also be included in this phase to build strength in important muscle groups such as the legs and core. Since the base phase is the easiest on the body, it can be anywhere from four to eight or more weeks in length.

Strength

The second phase of periodization training focuses on building strength and speed with the inclusion of more specific speed workouts and hill sessions while maintaining mileage and weight training. In this phase, two easy runs per week will turn into two different speed sessions. The first speed session should be an increasing tempo run. Start with 15 minutes of your run at half marathon pace or slightly faster the first week and increase by 5 to 10 minutes each week until you are running 60 minutes at tempo pace. These workouts will help build strength in connective tissue and build muscle endurance to be able to get comfortable with running at your goal pace.

The second speed session can be alternated between shorter, faster repeats and hill workouts. Running on a track works best, but any uninterrupted road will do. After warming up for two to three miles, run intervals such as 4 to 8 repeats of between 1000 to 1600 meters at 5k to 10k race pace with short recovery periods of 1 to 2 minutes in between. Cool down for one or two miles. Every other week can include hill repeats of both uphill and downhill running at half marathon pace. Begin with four sets and build to eight to ten repeats by the end of the phase. Hill workouts are an excellent lower impact way to build strength and speed. Phase two will last about eight weeks in length.

Peak

The peak phase of periodization training is basically where your highest mileage and hardest workouts land. This is where you build confidence and tax your body the most while continuing to build fitness. With proper periodization, you should feel comfortable running at your goal pace for several miles during peak month. Continue with two speed workouts each week—one longer tempo run and shorter, faster repeats. Your track session will include double the repeats you were doing in the strength phase with distances ranging from 200 to 800 meters at 5k pace with one or two recovery minutes in between, for example. Form drills and strides should not be neglected during this phase, as it is a time to practice maintaining proper mechanics when fatigued.

Following the peak phase is two weeks of tapering right before your race. After this tough month of your hardest training, your body will beg for the taper weeks. Many runners usually dread these couple of weeks before a race because they feel they are losing fitness with the scaling back of volume and intensity. With proper phasing in training, you can push your limits during the peak phase and enjoy your taper, as you should. It is a time to let your body recover and focus on good nutrition and sleep to gather energy for race day. Periodization is a useful method to plan your training as it helps to gradually adjust your body to higher intensity and faster paces with a lower risk of overtraining or injuries. You are less likely to experience any setbacks during training using these cycles.

Strategies for the Long Run

A recent running magazine included an article about a professional marathon runner and when asked what their favorite training workout was, they answered “the 20-mile long run”. The assumption is that most readers probably responded with something along the lines of “Are you kidding me?!”. For most runners, the long run, especially when it gets up to that 18-mile point, is dreadful. Yet, the long run is probably the most important session of the week. After all, the race is just one really long run.

It has been recommended in several training plans to perform the long run in a long, slow distance (LSD), which has several benefits for race preparation. Running at 60-70% of 5k pace for these long distances will over time increase glycogen storage in the muscles, which means more readily available energy. The body does this by depleting the glycogen in our muscles during the run, which will cause the body to adapt by storing more glycogen. Another benefit of the LSD run is the increase in oxygen provided to the muscles by the growth of capillaries, where the carbon dioxide-oxygen exchange occurs, and mitochondria, where carbon dioxide and oxygen are converted into energy. These physiological reactions to running are the reason runners get faster and last longer over time through consistent training.

One downside of always performing the long run at LSD pace is boredom. There are only so many routes we can choose to get 20 miles done. A good strategy for these runs is to break it up into quarters on your route and in your mind. For example thinking of 20 continuous miles seems like forever. Breaking it up into four 5-mile segments is more tolerable. This is a good way to run the actual marathon, too! Another downside to choosing LSD is the lack of adaptation to running at goal pace and practicing what really happens during a race.

Many marathon training programs include long runs with at least a few goal-paced miles throughout. The purpose of these types of training sessions is to practice running fast on tired legs to mimic what race day will feel like. There are a variety of options to incorporate goal-paced miles, but it is important to be specific when heading out for these sessions, as it can be very taxing on the body. As after a race, you do not want your body to need days of recovery following your long run. It is an ideal option to alternate between goal-paced and conversational-paced sessions each week.

Goal-paced long run sessions can make these ‘dreadful’ training runs more tolerable, and help the time pass more quickly. Below are some great variations to the long run to alternate throughout your training cycle. As mentioned previously, the interval sessions can be very fatiguing and should begin with a few repetitions and miles, and gradually increase as your fitness improves.

• Mid-run tempo: Run 3-5 miles at conversational pace + 3-5 miles at goal pace + remainder at conversational pace

• Mile repeats: Run 3-5 miles at conversational pace + 3-5×2-3 miles at goal pace with 1-3 minutes at easy pace in between + remainder at conversational pace

• Fast finish long run: Run 75% of the long run at conversational pace + 25% at goal pace. As your fitness improves, build up to 50% at easy pace and 50% at goal pace

• Ladder: Run 3-5 miles at conversational pace + intervals of one to five minutes at goal pace with one to two minutes easy in between each + intervals back down from five to one minute at goal pace + remainder at conversational pace

• Ladder progression: Run 3-5 miles at conversational pace + 4 miles at goal pace+15sec + 3 miles at goal pace + 2 miles at goal pace-15sec + 1 mile at goal pace-30sec, all with one mile at easy pace in between. The goal of this progression run is to begin the first interval a little slower than goal pace, the next segment at goal pace, and then the last two segments of two and one miles even faster, finishing that last mile at a fast tempo pace.

These five workouts are great for building stamina and strength, as well as practicing your desired race pace, especially when your legs are fatigued. Alternating between options such as these with conversational-paced runs will ease your mind when preparing for long runs. The LSD run every other week will reduce the stress on the body and help recover faster than the goal-paced long runs.

In a properly organized marathon training schedule, you will find many different workouts spread out throughout the week, which all serve a purpose. If your goal is to simply finish the race, you technically can skip all of the speed sessions and tempo runs and perform all runs at an easy pace. If you skip the long run session in the training plan, you would have a very difficult time finishing the race. Therefore, the long run is the most important session of the week. The variations mentioned above may leave you somewhat near exhausted, but completing them will be a great asset to getting comfortable at your goal pace and enhancing confidence going into your races.

Balanced Hormones for Better Performance

The body undergoes several different changes during exercise. As much as non-runners may constantly tell their running friends how bad the sport is for the knees or heart, the fact is quite the opposite. Running produces an extraordinary amount of benefits to the body. From better heart health, to improved lung function and joint mobility, runners have an advantage towards a longer and more satisfying life. Many of the benefits and changes that occur during training are straight forward, while others are harder to understand. The effect on the endocrine system is one of the more confusing topics for runners. The endocrine system is responsible for the secretion and regulation of the body’s hormones, which play a significant role in performance improvement.

It is useful for athletes to understand the function of different hormones in order to train properly and safely for endurance events. In many cases, too much information on the benefits of certain hormones has caused some athletes to go to extremes trying to increase the amount in their bodies. From sleeping in high elevation to using performance-enhancing drugs—there are definitely many ways to ‘artificially’ raise hormone levels in the body, but with negative consequences, and possibly no beneficial outcomes. The key to getting the most benefit from the endocrine system for running performance is to keep hormonal balance. When it comes to training, the most important hormones to pay attention to are growth hormone, insulin-like growth factor, cortisol, and testosterone.

Growth Hormone

The pituitary gland in our brains naturally secretes growth hormone in bursts, usually following stress, exercise, or trauma. Although the levels of this hormone vary throughout the day, it is usually increased during the night. Since growth hormone is responsible for the development of bones and cartilage, it makes sense that more of it is produced during childhood and adolescent years as opposed to adult years. The role of growth hormone for runners, or any athlete for that matter, is to facilitate adaptation to exercise, which naturally occurs during rest and recovery periods. It stimulates protein production and helps the body utilize fat for energy, therefore helping runners last longer during endurance events. This is a commonly used performance-enhancing drug in the bodybuilding world as well, since it helps promote gains in size and strength.

Insulin-like Growth Factor

Insulin is produced by the pancreas and is responsible for storing glycogen and glucose in the body. During exercise insulin is suppressed to ensure that glycogen is used as fuel instead of for storage. Insulin-like growth factor has the same structure as insulin, except it is produced in the liver. This hormone works alongside growth hormone to help repair muscle damage caused by exercise. These factors make artificial supplementation attractive to athletes. Although this hormone is considered a banned substance, many are still using it despite the significantly negative side effects. Since insulin-like growth factor contributes to muscle growth and repair, it has been linked to cell growth as well, allowing tumors to survive and possibly grow, increasing the risk of death from cancer. Making sure to supply the body with adequate food, especially from animal proteins, is helpful in naturally maintaining a proper balance of this hormone.

Cortisol

You have probably heard of this hormone when reading or learning about stress and the “fight or flight” response. Cortisol is a hormone produced in the adrenal glands of the body. The natural response during any stressful situation is for these glands to secrete cortisol temporarily to keep our mental state more alert and our bodies ready for action. Hard training puts the body under a type of stress that creates a similar response. The problem with cortisol is the negative effects from its prolonged elevated levels, which is common during overtraining. Too much cortisol breaks down muscle tissue and stores more fat in cells. This eventually leads to a decrease in performance. One way to combat this imbalance is to include proper rest into training plans and avoid overtraining syndrome, which includes symptoms of exhaustion, poor performance, and irritability.

Testosterone

When it comes to running, testosterone is responsible for supporting the growth of muscles and aiding in recovery. Intense workouts, such as interval training or speed work can increase testosterone in the body leading to muscle mass gains and shorter recovery periods over time. Overtraining and prolonged running can decrease levels. Testosterone is another commonly used performance-enhancing drug by endurance athletes for the shorter recovery benefit and bodybuilders for the massive muscle gain benefit. Negative side effects of high testosterone levels are numerous and include behavioral changes, increased risk of heart attack, impotence, and acne. Balancing testosterone levels to benefit your running naturally is as easy as mixing up your running plan and adding in high intensity sessions.

These four hormones are just a few of the many that are involved in running performance. As with any stressful situation, including trauma, injury, and personal tribulations, running increases and/or decreases the levels of hormones in the body. This response is a natural one. Understanding the effects of hormonal imbalance is important in order to learn ways to manage. Artificially increasing hormone levels for the sake of performance improvement does give athletes an advantage, which is why these practices are banned from sports. It is always best to naturally balance out hormone levels, instead of exaggerating the levels of some, in order to avoid harmful side effects.

Vitamins: Do Athletes Really Need More?

Diet and exercise go hand in hand these days. Most people change their diets when they begin an exercise program, or at the least, they become more mindful of what they eat and drink. Whether you are exercising to lose weight, gain muscle, train for a marathon, or simply to maintain a healthy heart, diet will play a big role in the outcomes. Many active people include supplements in their diet to get more nutrients that may be missing in their regular diets or for the sake of enhancing their performance or recovery. The best approach to nutrition is to eat a well-balanced diet from every food group, making sure to include all vitamins and minerals your body needs. For the majority of people who live a busy lifestyle, this may not always be possible.

In any popluation many factors can affect what the body needs such as illness and disease, regular diet, activity level, genetics, and even the amount of time we spend indoors versus outdoors! People who lower their food intake to lose weight end up lacking necessary nutrients the body needs. On the other spectrum, high intensity athletes, especially marathoners, tend to lose nutrients and not replace them sufficiently due to their higher metabolic rates. Both of these categories require a certain amount of nutrients, including vitamins and minerals in order for the body to perform at any state and maintain proper organ function.

Since many vitamin and mineral supplement bottles are labeled with a notice that states they are not FDA approved, many people are opposed to taking them. It isn’t until they develop a symptom or certain results from routine blood work that they pay more attention to taking the essential missing nutrients. It would be helpful to get evaluated by your doctor and get routine blood work done before any negative symptoms or illness develop, since it is possible that a body can naturally not produce or absorb certain nutrients even when given a wholesome diet. If you are trying to lose weight and know that you are cutting out certain food groups, or are an athlete performing at higher intensity levels or for long durations, you may want to consider including proper supplementation to keep your body going.

Calcium and Vitamin D

Bone health is a popular topic throughout life. Most children are brought up learning to drink calcium-rich milk every day to make and keep bones strong. Besides being a bone-strengthener, calcium is also in charge of other vital roles in our bodies such as nerve conduction, muscle contraction, and aiding in blood clotting. Many food sources are rich in calcium besides milk, including almonds, kale, broccoli, yogurt, and most other dairy products. Sufficient amounts of Vitamin D should also be included as it is responsible for the calcium absorption, as well as other functions such as helping reduce inflammation in the body and for immune health. More recent studies have shown that insufficient Vitamin D intake may lead to more incidences of stress fractures and decreased performance levels. Foods high in Vitamin D include milk, mushrooms, eggs, and most seafood. The easiest way to increase vitamin D intake is to spend an extra ten minutes in the sunlight!

Iron and Vitamin C

The most important role iron plays in the body is to transport oxygen in the blood to the tissues, basically ensuring proper muscle function. This is a major factor for athletes who want to perform at their best. During recovery from strenuous exercise, such as long distance running, iron helps produce new cells and repair our damaged muscles. It is important for high intensity and endurance athletes to include the recommended amount of iron in their diets. Women in particular should be aware that their requirements are higher than for men. Iron deficiency can be caused by blood loss, poor absorption, or inadequate intake through diet. The antioxidant Vitamin C plays a role in the proper absorption of iron, as long as it is ingested at the same time. Vitamin C is also vital for the repair of damaged tissue and immune health.

B Vitamins

For active individuals who train at high intensities or for prolonged periods, it is essential to include the recommended amount of B-vitamins in order to be able to perform at their best. This important group of substances is in charge of the proper metabolism of macronutrients—carbohydrates, proteins, and fats. Some B-vitamins help our bodies rely on carbohydrates for energy, which may assist in delaying the glycogen depletion process. This is desirable for a marathon runner who wants sustained energy for as long as possible. These vitamins are abundant in many food sources, so it is not difficult to ensure adequate intake. Fortified cereals, vegetables, lentils, animal products, and nuts are all rich in most B-vitamins.

Magnesium

Many vitamins, minerals, and antioxidants aide in the metabolism of macronutrients, including magnesium, which is essential for muscle health. Its role in protein synthesis is especially important for the recovery process when muscle tissue is broken down during exercise. Magnesium also plays a role in oxygen uptake, therefore making it beneficial for high intensity and prolonged exercise, since there is a need for higher oxygen requirements. During activities that result in increased sweat loss, magnesium is known to be one of the electrolytes lost during the process, which will decline exercise performance if not replaced. Good high-magnesium food sources include seeds, legumes, bananas, avocados, and dark chocolate.

Upper Intake Level

Although dietary requirements of vitamins and minerals vary from one individual to another, it is important to note that there is a maximum. Many studies have shown there are benefits to including the proper amount of vitamins in an athlete’s diet, but going beyond the maximum level will not enhance performance further. There are harmful effects of ingesting too much of any nutrient, such as increased risk of toxicity, interference in absorption of other medications and nutrients, immunosuppression and oxidative damage. As mentioned earlier, it is best to include a balanced diet of all food groups in your daily diet with plenty of fruits, vegetables, and other fortified sources before opting for supplementation. If your diet is lacking in a particular food group, such as in a vegan or vegetarian diet, or a low calorie diet used for weight loss, and it is difficult to include a variety of vitamin-rich food sources, supplementation may be necessary. Many health conditions and diseases can alter the amount of nutrients and vitamins our bodies require, which is why it is always best to consult a medical professional before modifying your diet.
