U.S., April 3 -- ClinicalTrials.gov registry received information related to the study (NCT06906393) titled 'Adaptations to 4-s Sprint Interval Training at Different Intensities' on March 24.
Brief 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...
