ABSTRACT
The effect of physical exercise in immune function has been extensively studied. The intensity and duration of physical exercise have considerable influence in immunologic parameters. However, few studies have compared different exercise intensities in different stages of a physical training program. Thus, the aim of this study was to verify the metabolic, hormonal and immunologic changes before and after acute intermittent swimming exercise, following different stages of training program. Seventeen male swimmers were evaluated in three stages of training. The intensity of the three sessions was 90% (anaerobic potency – PAN), 70% (aerobic potency - PAE) and 98% (lactate tolerance – TLA) of the maximal speed from the best time of the distance, resulted from peak performance in competition. Blood samples were collected pre and immediately after exercise for cells counting and measurement of substrates and cortisol concentrations. It was used ANOVA to verify the significance of difference (p
