Experimental: 4-s sprint inertial load training
Participants trained three times a week for eight weeks following the training program consisting of 30 bouts of 4s all-out cycling on an inertial-load ergometer with progressively decreasing recovery time (30 to 24 to 15s).
Other: 4-s sprint inertial load training
A program employing 30 bouts of 4s inertial load sprint training with progressively reduced recovery time (30 to 15 s) between sprints is effective for improving blood volume, VO2peak and maximal power.
- Cardiovascular changes [ Time Frame: Pre and post training (8 weeks) ]Maximal oxygen consumption (VO2max) is an indicator of health and fitness. The investigators measured VO2max with a graded exercise using electronically braked cycling ergometer.
- Blood volume changes [ Time Frame: Pre and post training (8 weeks) ]Hematological variables can effect the performance of the people. The investigators measured total blood volume, red blood cell volume, and plasma volume before and after training.
- Performance changes [ Time Frame: Pre and post training (8 weeks) ]Study participants trained at maximal anaerobic power for 4-s. Therefore, the investigators measured maximal anaerobic power with different testing methods.
