DOES HIGH-INTENSITY RESISTANCE TRAINING AFFECT AN ATHLETE'S IMMUNE FUNCTIONS?

Abstract

This research aims to comprehensively examine the latest literature on the effects of high-intensity resistance training on the immune system's long-term performance. Many athletes and active individuals believe that moderate physical activity can enhance resistance to minor illnesses like upper respiratory tract infections (URTI), while intense exercise may have the opposite effect. The study involved 90 athletes who regularly train at Ahly Sporting Club and were divided into three groups: Group 1 included 30 athletes at rest, Group 2 comprised 30 athletes after normal training, and Group 3 had 30 athletes after intense training. Athletes who undergo intense training have lower total white blood cell counts than those who train at normal or resting levels. However, their neutrophil numbers slightly increase after heavy training, while lymphocyte and natural killer cell levels decrease. Additionally, those who undergo heavy training have higher PHA-induced proliferation levels but show a decline in serum immunoglobulin levels, mucosal immunoglobulin concentrations, and plasma glutamine levels. To prevent upper respiratory tract infections in athletes, it is essential to avoid over training and provide sufficient rest and recovery during and after training and competition. It is currently uncertain whether moderate exercise training can prevent infectious illness among the general population.
