It is extensively acknowledged that insufficient power (calorie) intake in periods of intense training can compromise the immune system and consequently enhance susceptibility to an infection. In a current single-blind, placebo-controlled study ( eight ), it was reported that four wk of oral supplementation, with a mix of vitamin C (500 mg/day) and vitamin E (400 IU/day), markedly attenuated the release of IL-6 from lively muscle and the plasma IL-6 and cortisol response to 3 h of dynamic two-legged, knee-extensor exercise at 50% of maximal power output in contrast with placebo.
Several studies point out that the incidence of symptoms of higher respiratory tract illness is elevated within the days following prolonged strenuous endurance events and it has been generally assumed that that is due to the momentary train-induced despair of immune perform (Gleeson,2006).

In addition to the presence of antigens, leukocyte perform can be influenced by endogenous chemicals, including hormones, neurotransmitters, and cytokines, and the plasma focus of these may change during train.

Further, previous analysis discovered that intense train in a glycogen-depleted state does have a damaging affect on circulating stress hormones, leading to decreased immune function22.

Nutrient availability has the potential to have an effect on almost all points of the immune system, four , 5 , 6 as a result of many nutrients are concerned in power metabolism and protein synthesis.

Scientific studies continue to disclose the connection between the immune system and gastrointestinal function27, with increased injury to the intestine ensuing from endurance running.
