Strenuous bouts of prolonged exercise and heavy training are associated with depressed immune cell function. Furthermore, inadequate or inappropriate nutrition can compound the negative influence of heavy exertion on immunocompetence. Dietary deficiencies of protein and specific micronutrients have long been associated with immune dysfunction. An adequate intake of iron, zinc and vitamins A, E, B6 and B12 is particularly important for the maintenance of immune function, but excess intakes of… 
Exercise and food factors.

TLDR
Various food factors that have been reported to be effective for improving health promotion, along with the relevant physiological changes that occur during exercise are described.
Molecular Pathways Mediating Immunosuppression in Response to Prolonged Intensive Physical Training, Low-Energy Availability, and Intensive Weight Loss
TLDR
A number of molecular pathways presumably explaining immunosuppression in individuals going through prolonged periods of intense training with low-energy availability are elucidated, reinforcing the perception that the way in which weight loss is achieved has a distinct effect on how the immune system is modulated.
The effect of dietary control and carbohydrate supplementation on the immune and hormonal responses to rowing exercise.
TLDR
Car carbohydrate supplementation to athletes in the post-prandial state undergoing a 1 h rowing trial resulted in attenuation of the post the exercise increase in peripheral blood lymphocyte concentration, but had little effect on the ability of PBMCs to produce cytokines following stimulation, natural killer cell activity, stress hormone concentrations, exercise performance, or self-reported incidence of illness during the 14 d period following the experimental trial.
Effects of nutritional supplements on the immune function of athletes
TLDR
This 16-week intervention study on 267 athletes found that regular ingestion of the probiotic reduced the extent to which training was negatively affected in endurance athletes when infection was present, and increased both S-IgA concentration and secretion rate over time.
Protein feeding and exercise recovery
TLDR
It is demonstrated that an acute bout of resistance exercise further augments the protein synthetic rate of muscle already stimulated by food intake, and the mechanism(s) underpinning the suggestion that a high protein diet may potentiate a better maintainence of endurance performance following intensified training could not be definitively elucidated.
Assessing immune function changes in exercise and diet intervention studies

  • Medicine
    Current opinion in clinical nutrition and metabolic care
  • 2005
TLDR
There is too little evidence at present that correlates individual markers with global health improvement and therefore assessing changes of immune function requires a thorough methodological approach targeting a large spectrum of parameters.
Effects of Oral Supplementation with Cystine and Theanine on the Immune Function of Athletes in Endurance Exercise: Randomized, Double-Blind, Placebo-Controlled Trial
TLDR
Observations suggest that the ingestion of CT contributed to suppressing the change in inflammatory response, prevented a decrease in the immune function, and prevented infection and reduced symptoms when infected associated with continuous intense exercise.
The Effects of Diet, Exercise, and Sleep on Brain Metabolism and Function
TLDR
An active lifestyle (healthy diet and exercise) and 6–7 h of sleep in middle age and late life can be two possible intervention strategies to retard and postpone the onset of neurotraumatic, neurodegenerative, and neuropsychiatric disorders.

TLDR
Data from two studies of 30 marathon runners and 10 triathletes suggest that carbohydrate compared to placebo ingestion is associated with higher plasma glucose levels, an attenuated cortisol and growth hormone response, fewer perturbations in blood immune cell counts, and a diminished pro- and anti-inflammatory cytokine response.
Immune response to heavy exertion.

TLDR
Theimmune response to heavy exertion is transient, and further research on the mechanisms underlying the immune response to prolonged and intensive endurance exercise is necessary before meaningful clinical applications can be drawn.

TLDR
In the elderly, impaired immunity can be enhanced by modest amounts of a combination of micronutrients, and low-birth-weight infants have a prolonged impairment of cell-mediated immunity that can be partly restored by providing extra amounts of dietary zinc.
Pre-exercise carbohydrate status and immune responses to prolonged cycling: II. Effect on plasma cytokine concentration.
TLDR
It is suggested that pre-exercise CHO status can influence the plasma cytokine response to prolonged cycling.
Essential fatty acids, immune function, and exercise.
TLDR
Essential fatty acids may determine alterations within the immune system following exercise, and future studies are necessary to evaluate the influence of the fatty acid composition on the inflammatory or immunosuppressive component following heavy exertion.

TLDR
Acute supplementation with a high dose of VC has little or no effect on the hormonal, interleukin-6, or immune response to prolonged exercise and combined ingestion of VC with CHO provides no additional effects compared with CHO alone.

TLDR
Enhancing intrinsic antioxidant defense by increasing exogenous antioxidant intake is theorized to be of long-term benefit to serious endurance athletes engaged in heavy training and competition.
Influence of carbohydrate status on immune responses before and after endurance exercise.
TLDR
The data indicate that the exercise and diet manipulation altered the number of circulating leukocytes but did not affect the decrease in lymphocyte proliferation that occurred after exercise.
Effect of glutamine supplementation on changes in the immune system induced by repeated exercise.
TLDR
The hypothesis that those aspects of postexercise immune changes studied are caused by decreased plasma glutamine concentrations does not appear to support the hypothesis.

TLDR
Of greater public health importance is the consistent finding of a reduction in URTI risk reported by fitness enthusiasts and athletes who engage in regular exercise training while avoiding overreaching/overtraining.
