Brief Summary
High-intensity interval training (HIIT) is an effective tool to improve cardiovascular fitness and maximal anaerobic power. Different methods of HIIT have been studied but the effect of a maximal effort cycling and very short exercise time (i.e., 4-s) with short recovery time (15-30 s) and a high number of repetitions (i.e., 30 bouts) is unknown.

Outcome Measures
Primary Outcomes (2)
Cardiovascular changes
Maximal oxygen consumption (VO2max) is an indicator of health and fitness. The investigators measured VO2max with a graded exercise using electronically braked cycling ergometer.
Pre and post training (8 weeks)
Blood volume changes
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.
Pre and post training (8 weeks)
Secondary Outcomes (1)
Performance changes
Pre and post training (8 weeks)
Study Arms (1)
4-s sprint inertial load training
EXPERIMENTALParticipants 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).
Interventions
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.
