Sprint Interval Training in Young Sedentary Adults
Sponsor: Sezer Taştan
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
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.
