Summary

The purpose of this study is to investigate the chronic effects (i.e., 8 weeks, 3 times per week) of training at 50% and 75% of maximal power with 4-s sprint interval training on physiological adaptations. We previously examined the effect of training with an all-out intensity (i.e., 100% of maximal power) and reported increases in cardiorespiratory fitness. Now, we propose to examine the effects of a lower exercise intensity domains on cardiovascular fitness and its ability to stimulate the cardiorespiratory system. We hypothesize that training at 50% and 75% of maximal power will improve cardiorespiratory fitness similar to our previous findings while reducing the rate of perceived exertion during the exercise session. It is anticipated that the group engaged in training at 75% of maximal power will experience greater improvements in comparison to the group training at 50%.
