Sick While Tapering? Here’s Why & Ways To Prevent It

Training for a marathon requires several months of hard running, at least decent nutrition, and adequate sleep. The last two to three weeks are extremely important to the training cycle, as it is when the body prepares for race day by enhancing recovery while maintaining the fitness gained throughout the prior months. The goal of this taper period is to get the body to a more relaxed state and fueled for race day. To reach this goal, there should be a gradual drop in mileage and heavy weight lifting, and a focus on proper nutrition. Many runners use this time to lounge on the couch and go overboard on the carb-loading, but it should be more structured than that! A drastic change in routine during the taper is not such a good idea because the body has been used to tackling loads of miles and exercise and a diet to sustain that activity level. It may shock the body and possibly cause illness. The common occurrence of illness during the taper period may be due to other reasons as well.

Overtraining Syndrome

Studies have been done to assess the response of the body’s immune system to physical activity. There is not much evidence to conclude that properly trained and recreational athletes are more susceptible to illness than non-athletes. However, there seems to be an effect on immune function with prolonged intense physical activity. The strongest correlation is the susceptibility to illness and the over-trained athlete. Overtraining syndrome is when there is insufficient rest with a high volume of physical stress, and many times this is combined with other stressors such as emotional, nutritional, and environmental stress. If this pattern continues, after a certain time chronic fatigue will set in along with poor recovery.

Low Plasma Glutamine

Over-trained athletes often present with low levels of glutamine in the body. Glutamine is an amino acid that is responsible for the healthy functioning of lymphocytes, which are the white blood cells that keep our immune systems working properly. With low levels of glutamine, athletes who are undergoing intense physical stress, as in overtraining syndrome, are more susceptible to infections. Although the main focus to prevent a drop in lymphocyte function is to avoid developing overtraining syndrome, glutamine supplementation is an option to keep levels where they need to be.

Post-Exercise Immunosuppression

There is a drop in some aspects of immune system functioning following exercise, especially intense exercise, such as a long cycle or run. This window of opportunity for infections can last between 3 to 72 hours. Some studies have shown that over-trained athletes who have a combination of stressors may extend this window even longer than a three-day period. This may be a reason why illness arises during the taper period. Our hardest training is performed right before the taper begins and with a window of opportunity extending to three or more days, we are more susceptible to falling ill. This is where proper nutrition is key. It is beneficial to have a wholesome diet full of the essential vitamins and minerals the body needs to lower our risk of developing infections.

Tissue Damage

Intense exercise causes tissue trauma that triggers higher levels of cytokines in the blood due to chronic inflammation. Elevated cytokines will causes a suppression of certain lymphocytes that are responsible for immunity. This occurs mostly in over-trained athletes who do not recover properly. A protective response of the body is automatic behaviors that will lead the athlete to decrease training intensity. This is due to the communication of cytokines with the brain to induce mood changes and fatigue.

Taper Illness Recovery & Prevention

The first plan of action to prevent taper sickness is to avoid falling into overtraining syndrome. Throughout the several months of training it is vital to incorporate enough rest time. Not every body is the same. Some tolerate less recovery than others. It is important to keep in mind that without proper recovery, our bodies cannot perform at their best. As mentioned above, good nutrition should also be a top priority every day during training. A diet full of essential nutrients and vitamins is key to keep our bodies working properly, as well as maintaining a low risk of acquiring infections.

If you are reading this while you are already sick and in the midst of your race taper, then the best action to take is to get plenty of rest during this time and drink a good amount of fluids. Nutrition is extremely important during illness, as our bodies require more energy to assist in the healing process. Appetite may be low or nonexistent during sickness, but it is vital to make sure to eat enough calories and make sure it is all from high-quality foods! The taper will require continued training runs at a lower intensity and volume, but if your illness consists of fever, body aches, and chest symptoms, it is best to take a few days off from physical activity. If symptoms are from the neck and above, such as a runny or stuffy nose and headache, it is usually safe to head out for easy runs. Remember, the taper period is not meant to improve performance and taking a few days off will not lower your fitness levels. Forcing running during this time while you are sick may only prolong your illness and negatively affect your race day outcomes.

The Role of Glutamine in Recovery

Whether you are an elite athlete or a recreational runner training for long distances, you are at risk for developing overtraining syndrome and other ailments. Marathon training requires us to engage in multiple strenuous training sessions several days out of the week. More advanced runners train somewhat intensely every day! Prolonged and intense exercise can increase the risk of muscle tissue damage, inflammation, cardiac dysfunction, decreased immune function, and overuse injuries. PHEW! That’s quite a list of negatives, but don’t be fooled—there is a way to avoid all of these!

When deciding what type of marathon training plan is right for you, it is important to know that all plans can be modified based on your needs. Some athletes require more rest and recovery days than others. There is a reason that these easy days are scattered throughout the training weeks in every plan. It is meant to decrease the risk of developing the negative side effects of too much running.

There are important vitamins and nutrients athletes specifically need in order to stay healthy. Although a good balanced diet, preferably higher in quality calories, may be enough to obtain all of these essential nutrients, sometimes supplementation is necessary. Getting in everything we need for a balanced diet is difficult to do day in and day out, especially if you have a busy schedule to begin with. Many athletes supplement their diets with extra protein, usually in the form of powder. The reason for this is that protein is crucially important for the health of muscles, bones, skin, cartilage, and blood in the body. When deciding which protein powder to use, it is best to choose one that includes the important amino acids, which are the building blocks of the protein we need in order to function.

Glutamine

One extremely essential amino acid that gets depleted with hard training is glutamine. The depletion is said to likely be from the demand for glutamine from different organs exceeding the supply in the body after exercise. The role of this essential amino acid in the body is to assist with protein synthesis to build stronger muscles, support the immune system, and for the enhancement of hydration in the body. After strenuous exercise, the depletion of glutamine can last up to six days, which can greatly affect the recovery process of muscle damage. The low state of this essential amino acid is also what causes athletes to be more susceptible to illness, such as colds and the flu, following hard training. Glutamine may also be depleted with other conditions such as trauma, burns, muscular dystrophy, and any other conditions causing stress in the body.

Muscle Repair

Muscle tissue damage is almost inevitable in athletes. The breakdown of muscle, causing tiny tears, is what builds strength. But this strength is only built during the recovery and healing process. This means that your muscles aren’t actually getting bigger and stronger while you are weight lifting—it all happens when you begin your rest period. Of course, nutrition will also play an important role in these strength gains. It is always a good idea to eat after a workout, especially after a strenuous run. A carbohydrate and protein-rich meal or snack is ideal, since this will help speed up the recovery process. As mentioned above, choosing a protein powder that includes the essential amino acids as part of a recovery shake is a good option to replenish the possibly lost glutamine. Glutamine alone also comes in the form of capsules, so this may be a quicker option for some athletes.

Immune Function

Glutamine is essential to immune function as it assists with lymphocyte proliferation and the production of cytokines. What does this mean? Well, lymphocyte proliferation is basically cell production and cytokines are molecules the immune system needs in order to communicate when there is infection, inflammation, or trauma. Without these processes, immunity is weak and cannot properly fight against bacteria. Studies have shown that the inclusion of glutamine following surgery, medical procedures, and trauma, especially in patients with a compromised immune system, resulted in lower levels of infection and shorter hospital stays. In the case of endurance athletes, studies have concluded that there have been less episodes of illness following strenuous training or races with the intake of a glutamine supplement.

Muscle Hydration

Glutamine assists in the absorption of water and other nutrients to keep our muscle tissues hydrated properly. Prolonged and intense exercise causes extreme stress and dehydration throughout the body. Glutamine supplementation has been shown to improve the hydration process by way of enhancing electrolyte and fluid absorption in the muscles. It may be beneficial to opt for electrolyte drinks that contain this nutrient and other branched-chain amino acids, usually labeled “BCAAs”.

If you are a runner looking to increase your training time and improve your performance, it is extremely important to pay attention to your diet. Many people have the thought that since they are exercising so much they can eat whatever they want and not worry about nutrition. Yes, the body will burn a load of calories with the hard workouts, but it will only impede strength gains and performance improvements if the body is not taking in the nutrients and vitamins it needs to repair and build. With all of the calories burned, essential nutrition gets depleted as well. This will only lead to fatigue, illness, and/or injury. The best way to get as many of these important nutrients from your diet is to make sure you are getting in enough quality carbs, protein, and fats from nutrient-rich foods such as veggies, fruits, and whole grains.

Running After a Race: The Reverse Taper

After several months of dedicated training, race day finally arrives and it is time to showcase all of that hard effort by running 26.2 miles. You finish the race, refuel with the goodies provided at the finish line, and feel accomplished. But now what? Whether you have an amazing race and set a personal record or have a disappointing one, your body goes through the same workload. The biggest mistake most marathoners make is not giving their bodies enough recovery time after the grueling training months and a demanding race.

After getting used to running most days of the week, or everyday for some, it is not the easiest task to take time off. It ends up being unenjoyably miserable and creates a sense of not feeling like oneself even after just a few days. If you had an amazing race and set a PR, you will feel anxious to continue the streak and get back on the training wheel as soon as possible. On the opposite spectrum, if the race did not go so well, you may feel like you need to start harder training right away, or worse—feel like you don’t deserve much time off. But this break is a very important step to improve performance for the next race.

Why Do I Need Such a Long Break?

The marathon and all of those hard training sessions damage the body in so many ways. Of course, if you trained properly, gradually increasing mileage over time, taking rest days as they should be, and fueling properly, the damage to the body is reversible and not detrimental. You do not have to be an elite athlete training 100+ miles per week to get this damage. Since most plans go up to twenty miles at the most training for the marathon, the extra six miles completed at the race, with most likely faster paces, is enough to damage the body just on race day alone.

Muscle Damage

The most obvious damage is done to the muscles. The significant amount of inflammation accumulated in the body after hard training runs and races is a normal process. The temporary inflammatory response to training is necessary in order to improve different fitness components such as strength, stamina, and VO2 max, but only if proper recovery is included in the mix. If you do not let your body recover effectively after a hard workout, then the next hard workout will only pile on more inflammation. Eventually, this stacking on of inflammation will turn into chronic inflammation and lead to injury. The key is to recover properly from every hard workout, especially the hardest workout in the entire plan—race day.

Cellular Damage

There may be times where you run a race, and do not even feel sore afterwards. This is probably the most dangerous time because it will be more likely that you will return to harder running too quickly. Although one may not feel sore or fatigued following a race, it is important to note that the race still induced muscle damage. Creatinine kinase (CK) is a substance that is measured in the blood that indicates skeletal muscle and cardiac damage. Increases in CK in the blood are usually brought on by intense or prolonged exercise, especially in the case of eccentric-type exercise, such as running downhill. Some studies show that this increase can last 3-4 days post-race, while others show it can take longer than seven days to bring these levels back to normal. Given this information, it is important to make sure to not judge your recovery time on how sore you are from your race.

Immune Suppression

Yet another reason a good break after racing is recommended is the impact of hard training on the immune system. The tissue damage that occurs during training and racing leads to the production of cytokines, which are basically substances secreted by the immune system that affect other cells in the body. This development of cytokines then increases the lymphocytes responsible for suppressing immunity. This process is what makes athletes, especially endurance athletes, more susceptible to infections. Although you may not get sick right after racing, this bodily response to the months of hard marathon training will increase your risk of getting sick and having to put a break on your training plan later down the line.

Reverse Taper

A good method to determine your plan to returning back to running after racing is to simply take your taper plan from before your race and reverse it. If your training plan called for a two week taper, then the reverse taper would also be two weeks in length. The few days leading up to your race were mostly easy, short runs, so the first few days back to running should be the same. A few speed sessions fall within these two weeks as well, but overall the mileage is much lower than peak mileage. The third week after the race is finally a good time to start weaning back into the type of running you were doing before. Of course if you follow this approach and your taper was longer, say three weeks, then this plan will take three full weeks until you are back to your prior training level.

It is a good idea to include some light strength training by week two to slowly begin getting your muscles used to exercising. It is important to keep these strengthening exercises similar to what you were doing before. Flexibility exercises and massage/foam rolling should begin as soon as possible to help keep sore and tight muscles flexible and circulated.

You Won’t Lose Fitness

During the reverse taper, runners feel they will lose fitness and get out of shape. There are several studies out there concluding that there is a minimal drop in fitness levels within the first couple of weeks of inactivity. VO2 max is a main indicator of fitness in athletes. It is the measure of the maximum amount of oxygen one is able to utilize during intense exercise. Within the first week of inactivity, there is an insignificant drop in VO2 max (up to 3%), and it will go as high as a 6% drop after two weeks. This is for athletes who decide to take the weeks off completely, instead of incorporating easy runs and other cross-training. Therefore, the drop is even less for those who get back into those easy runs within the first few days as explained above.

The reverse taper is an excellent strategy to use when recovering from a marathon. It lets you continue your running while giving you ample time to rest and incorporate other recovery methods such as massage and cross-training. Not planning adequate time after racing will only lead to overtraining syndrome and a higher risk of injury. It is important to listen to your body during these few weeks post-race and gradually increase mileage. A proper break from intense training will only lead to better performance in your next race!
