The effects of 24 and 72h rest after single session of high intensity exercise on humoral immune and blood lactate levels in Kabaddi athletes

Intense training sessions may affect multiple organ systems, especially the immune system and blood variables, that may have different effects on athletic performance, and these effects are unknown. The purpose of this study has been to investigate the effects of single session of high intensity activities on humoral immune and blood lactate levels immediate, 24 and 72h after exercise in Kabaddi athletes. For this reason ten elitist Kabaddi athletes (age 21.5±1.6 years, height 174.12 ±2.4 cm and weight 62.4±4.1 kg) took part in this study that the type of it was mid experimental. Subjects were asked to perform high intensity exercises in length of 110 min. Blood samples were taken at pre, immediately, 24 and 72h after exercise and Lactate maximum (Lacmax) were measured throughout exercise. Data were analyzed by using paired sample student T-test and General liner model, and we used of SPSS 18 for this reason (P<0.05). All levels of immunoglobulins were decreased immediately after exercise, but Lacmax had significant increase. After 24h, the amount of IgG (955.38±0.6) was decreased and the amount of IgM (210.16±1.1) and IgA (288.25±2.4) were decreased than before and immediately after exercise, and all immunoglobulins were significant after exercise rather than before exercise (P<0.05). Also, Lacmax levels after this period has increased insignificantly compared to before exercise (P<0.05). IgG levels (1230.41 ± 3.2) increased after 72-hour recovery period, so that this increase compared to before, immediately after and 24 hours after exercise was significantly (P<0.05). The amounts of Ig M (162.02 ± 1.01) and IgA (238.32 ± 0.98) after this period of rest had insignificantly decreased (05/0P <). Lacmax value was a significant difference between immediately after and 24 hours after this period (P<0.05). The results showed that 24 hours after high intensity exercise, blood lactate level and amount of immunoglobulin have changes, that in some cases this rest period may be effect to restore some of the variables to basic levels and about others, more time is required. Then, the use of proper rest periods vary according to a variable and it must apply in training programs with needs of training.
