Calcif Tissue Int 92 2 — There is also not enough evidence that glutamine and amino acids somehow help to prevent infections. The body has a large storage pool of these nutrients, and studies show that exercise alone cannot significantly reduce these reserves.

A recent hypothesis has been propogated over the latest studies. Because the immune system is so complex and diverse, the approach should rather be to use a combination of supplements rather than studying them individually. It is stated that using large doses of a single supplement may perhaps not be as effective as strategy using a cocktail-type approach with a combination of supplements together.

The table below is a review of all available studies on the use of supplements that can play a role in the immunity of athletes as well as recommendations as to their use. Human studies show strong reduction in illness rates during heavy training and mild stimulation of mitochondrial biogenesis and endurance performance in untrained subjects; anti-inflammatory and anti-oxidative effects when mixed with green tea extract and fish oil.

Source: Walsh et al. The physiological effects of certain polyphenols such as quercetin, EGCG green tea extract , turmeric, lycopene and resveratrol generated a lot of interest from exercise immunologists due to their anti-oxidative, anti-inflammatory, anti-pathogenic, cardioprotective, anti-carcinogenic effects.

Several recent studies of quercetin supplementation in humans have been conducted to determine its mechanism of action on the post-exercise inflammation, oxidative stress, immune dysfunction, its ability to improve endurance and reduce incidence of infections due to physical stress.

When quercetin combined with other polyphenols and nutrients such as green tea extract, iso-quercetin and fish oils, it was noted that there was a significant reduction of inflammation induced by exercise and oxidative stress caused by exertion.

In addition, improved innate immune system functions, the ability to defend themselves and to protect themselves from pathogen, are largely increased.

Quercetin has several bioactive effects and is the polyphenol the most absorbed in the intestine. However, yet to be determined remains the optimal dose for the athletic population and the best cocktail from which they could benefit most during each of the following: periods of intense workouts, trips, and competitions as well as during their recovery.

As the saying goes: Prevention is better than cure. While there is no exact method to completely eliminate the risk of catching a cold or any infection, there are different lifesytle and nutritional strategies that each athlete can implement on a daily basis, during periods of intense training and when traveling.

The following recommendations are made by the group of BASES experts to reduce immunosuppression encountered during prolonged high-intensity efforts and to reduce the risk of infections.

It is well documented that moderate exercise prevents many infections and greatly Recharge Wallet App immune system function. In contrast, among imnune athletes Achieve optimal metabolism naturally train at Achieve optimal metabolism naturally faster pace youtn at a Fat loss motivation tips intensity, the risk of illness increases significantly and the effectiveness of the immuune system to fight zthletes is Hycration. Other factors, including exposure to pathogens, lifestyle, sleep Achieve optimal metabolism naturally recovery, the overall nutrition of the athlete and the psychosocial aspects should be considered in addition to volume and intensity of training. Each episode of acute prolonged exercise performed at high intensity causes a significant physiological stress on immunity and host-pathogen defense, in addition to having an effect on the level of stress hormones, cytokines, pro- and anti-inflammatories and increased oxidative stress. From these facts, many researchers have examined the nutritional strategies to implement before, during and after workouts and travel to major competitions to better understand how it is possible to prevent infections in athletes and maintain a strong and healthy immune system. We briefly present solutions for minimizing these concerns as they can greatly affect the performance of your athletes.
