This review summarizes research discoveries within 4 areas of exercise immunology that have received the most attention from investigators: 1 acute and chronic effects of exercise on the immune system, 2 clinical benefits of the exercise—immune relationship, 3 nutritional influences on the immune response to exercise, and 4 the effect of exercise on immunosenescence. These scientific discoveries can be organized into distinctive time periods: —, which focused on exercise-induced changes in basic immune cell counts and function; —, during which seminal papers were published with evidence that heavy exertion was associated with transient immune dysfunction, elevated inflammatory biomarkers, and increased risk of upper respiratory tract infections; —, when additional focus areas were added to the field of exercise immunology including the interactive effect of nutrition, effects on the aging immune system, and inflammatory cytokines; and to the present, when technological advances in mass spectrometry allowed system biology approaches i. The future of exercise immunology will take advantage of these technologies to provide new insights on the interactions between exercise, nutrition, and immune function, with application down to the personalized level.
Alterations in the innate immune system due to exhausting exercise in intensively trained rats

The compelling link between physical activity and the body's defense system
In this review, we have focused on the effects of exercise on infection or antibody production. In the past, exercise immunologists largely focused on exercise and its effects on infection. Research on the effects of exercise on antibody response began in the s with a primary focus on whether regular exercise helps to minimize the risk of infection. Positive results from these early studies indicated that exercise affects higher survival rate. Based on the results of these studies, researchers then investigated the exercise-induced elevation of plasma antibody levels. It has been suggested that exercise of moderate intensity could be a helpful and effective adjuvant for human health.
Exercise has a variable effect on the immune system. The underlying reasons for this variability are multifactorial and include infectious, neuroedocrine, and.
Exercise and immunity
The physiological function of the immune system is to defend against infectious microbes; even non-infectious foreign substances and damaged cell products that can elicit an immune response. The response from exercise, both acute and chronic, will have an effect on the components of the immune system. The immune response that occurs depends on the intensity and duration of exercise. Moderate intensity exercise will stimulate various parameters related to cellular immunity so that it can reduce the risk of infection, while high intensity exercise will result in a reduction in the same parameters, which will increase the risk of infectious diseases.

Metrics details. Immune function may influence the ability of older adults to maintain or improve muscle mass, strength, and function during aging. Thus, nutritional supplementation that supports the immune system could complement resistance exercise as an intervention for age-associated muscle loss.

Зеленоватое, оно было похоже на призрак. Это было лицо демона, черты которого деформировали черные тени. Сьюзан отпрянула и попыталась бежать, но призрак схватил ее за руку. - Не двигайся! - приказал .
Двухцветный посмотрел на часы Беккера. Его лицо казалось растерянным. - Обычно я напиваюсь только к четырем! - Он опять засмеялся. - Как быстрее добраться до аэропорта. - У входа возьмешь такси.
Через пять минут автобус, подпрыгивая, несся по темной сельской дороге. Беккер повернулся к панку. - Этот тарантас когда-нибудь остановится.
