NCT ID NCT05513300
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Stanford study compares high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) in 135 healthy but sedentary adults. Over 12 weeks, participants will exercise three times a week for about an hour. Researchers will measure changes in fitness, muscle strength, body composition, and molecular markers like genes and proteins to see which type of exercise leads to better health outcomes.
