What this Trial Is About
This research aims to explore how intermittent running exercises with different interval lengths and lower intensities than high-intensity interval exercise affect energy use during and after exercise, as well as blood sugar control in healthy, recreationally active adult men aged 20 to 45. The study compares these intermittent exercises to moderate-intensity continuous running to better understand their impact on metabolic health. Participants will complete three different running trials in a random order, including moderate-intensity continuous running and two forms of interval running with 5-minute and 2-minute cycles at varied intensities. Each trial consists of a 3-minute warm-up, 40 minutes of running, and then 30 minutes of seated rest for post-exercise measurements. Trials are spaced with at least 4 days of rest and no more than 14 days apart. During the study, researchers will measure muscle oxygen levels, resting metabolic rate, total energy expenditure, substrate use, and appetite sensations across 70 minutes including exercise and recovery. Participants will be monitored for muscle oxygen saturation and metabolic changes, with procedures to minimize movement during resting periods. The entire process ensures precise tracking of physiological responses to different running exercise patterns.
