Quick workouts may improve fitness in couch potatoes
NCT ID NCT07596836
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a 6-week program of sprint interval training (short, intense bursts of exercise) could improve cardiovascular fitness in healthy but sedentary adults aged 20 to 25. Forty participants were split into two groups: one did supervised cycling sprints three times a week, while the other continued their usual inactive routine. The main goal was to measure changes in VO2max, a key indicator of heart and lung fitness.
