Study 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.
Primary Outcome
Maximal oxygen consumption (VO2max) is an indicator of health and fitness. The investigators measured VO2max with a graded exercise using electronically braked cycling ergometer.
Interventions
- OTHER 4-s sprint inertial load training
