RESUMO

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. To this point, we aimed 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 analyzed in three stages of training, using the intensity of the three sessions was 90% (anaerobic potency ANP), 70% (aerobic potency - AEP) and 98% (anaerobic ability ANA) 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. Lactato increased significantly after the three different stages of training program, glucose post exercise in the ANP and AEP sessions, respectively. Glutamine increased significantly in AEP and ANA. Increased cortisol levels were also observed in AEP and in ANP. Leukocytes increased significantly after the three different sessions. There were no significant differences in lymphocytes, neutrophils e basophils. The eosinophils decreased in AEP and ANA. Monocytes no significant differences after the three different stages of training program, however decreased significantly on AEP. The immunoglobulins did not change of the three exercise patterns of pre and post-exercise. In summary, the protocoll intermittent swimming exercise following different stages of training the alterations capacity metabolic, hormones parameters and leukocytes any populations, favoring however health condition, so illnesses to not present.
