This study aimed to investigate the short and long-term effects of resistance exercise training (RET) performed at different intensities (moderate and submaximal) on red blood cell (RBC) deformability and aggregation. 14 young male subjects were divided into two groups: Moderate intensity group performed 3 sets of 12 repetitions at an intensity corresponding to 70% of one-repetition maximum (1RM) whereas submaximal intensity group performed 3 sets of 6 repetitions at 85% of 1RM for 6 weeks. Blood samples were obtained just before and immediately after the RET on the first and last day of the program. Hemorheological parameters were determined using an ektacytometer (LORCA), hematological parameters were evaluated by a hematology analyzer. RBC deformability was found to increase in both groups immediately after the RET but this elevation was significant only in the moderate intensity group on the first day. RBC aggregation significantly increased in both groups immediately after the RET on the first and last day of the program. It is concluded that RET performed at an intensity corresponding to 70% of 1RM alters RBC deformability more than training performed at 85% of 1RM. On the other hand, both training protocols affect RBC aggregation in a similar way. |
