Summary

This randomized controlled trial evaluated the effects of a 6-week supervised sprint interval training program on cardiorespiratory fitness in healthy sedentary young adults. Forty participants aged 20 to 25 years were randomly assigned to either a sprint interval training group or a control group. The sprint interval training group completed supervised cycle-ergometer sessions three times per week for 6 weeks, while the control group maintained their usual sedentary routine. The primary outcome was maximal oxygen uptake (VO2max). Secondary outcomes included resting heart rate and 6-minute walk test distance. The study aimed to determine whether a short-term, time-efficient sprint interval training program could improve cardiovascular capacity and functional exercise performance in sedentary young adults.

Interventions

BEHAVIORAL

Sprint Interval Training

The sprint interval training intervention consisted of supervised cycle-ergometer sessions performed three times per week for 6 weeks. Each session included a 5-minute warm-up at 50% VO2max, followed by 4 to 6 repetitions of 30-second all-out sprint bouts on a Monark 894E cycle ergometer, with 4-minute active recovery periods between sprints. The number of sprint repetitions was progressively increased from 4 repetitions in the first two weeks to 6 repetitions in the following four weeks.
