Effect of single session of competition like specific exercise on hematological indices in members of Iranian national aerobic gymnastics team

Exercise can influence hematological parameters related to performance.The purpose of this study was to determine the acute effect of single session of competition likespecific exercise on hematological indices in members of Iranian national aerobic gymnasticsteam. In this semi-experimental study, seven male members of Iraniannational aerobic gymnastics team (mean age 22.78 ± 1.72 years; weight, 68.50 ± 3.50kg; height,172.50 ± 4.07 cm) voluntarily participated. The exercise session was about 32 min consisting of 10min of general warm-up, 1 min and 45 seconds of specific group exercises with music, 10 min ofspecific warm-up, 6 min of reviewing the exercises, 4 min of relaxation and meditation, and 1 minand 45 seconds of the main competition at the end. 10 ml blood samples pre and post exercisewere taken from arm vena. To examine changes in the hematological variables, dependent t-testwas used at P<0.05. Significant increases were found in platelet percent (p=0.02), bloodcell count (p=0.01) and lymphocyte count (p=0.001); while other hematological parameters did notchange significantly (p>0.05) after a session of competition like specific exercise. Based on many unchanged hematologic parameters in this study, it seems that details of exercisetraining program don’t disturb hematological factors induced by exercise mode in aerobic gymnasticathletes.
