Background: Prolonged intense exercise has been associated with transient suppression of
immune function and an increased risk of infections. In this context, the catabolism of amino …

Multiple components of the immune systems in athletes exhibit transient dysfunction after
prolonged, heavy exertion. During this “open window” of impaired immunity, pathogens may …

The purpose of this study was to examine the effects of a probiotic supplement during 4 mo
of winter training in men and women engaged in endurance-based physical activities on …

Exhaustive exercise can cause a transient depression of immune function. Data indicate
significant effects of immune activation cascades on the biochemistry of monoamines and …

Abstract Position statement: The International Society of Sports Nutrition (ISSN) provides an
objective and critical review of the mechanisms and use of probiotic supplementation to …

Nutritional supplements are popular among athletes to improve performance and physical
recovery. Protein supplements fulfill this function by improving performance and increasing …

Heavy exercise is associated with an increased risk of upper respiratory tract infections.
Strenuous exercise also causes gastrointestinal (GI) symptoms. In previous studies …

The present study examined whether a high protein diet prevents the impaired leukocyte
redistribution in response to acute exercise caused by a large volume of high-intensity …

Heavily exercising endurance athletes experience extreme physiologic stress, which is
associated with temporary immunodepression and higher risk of infection, particularly upper …

Background: Heavy exercise induces marked immunodepression that is multifactorial in
origin. Nutrition can modulate normal immune function. Objective: To assess the efficacy of …
