Effects of Exercise Frequency on Muscle Size and Strength in Healthy, Untrained Young Adults
Sponsor: Cameron Mitchell
Summary
Resistance training (RT) is important for building and maintaining healthy muscles. An exercise frequency called "exercise snacks" involves short bursts of exercise throughout the day (\~5-15 minutes), but no studies have examined a gym-based RT exercise snack program. The invetigators will randomize 40 participants into one of two groups for 10 weeks: the control group will complete two full-body workouts per week (standard-frequency) and the experimental group will complete 10 mini-workouts per week (high-frequency). Muscle hypertrophy (size) and strength will be measured before and after the exercise program to determine if the participants had the same or different results.

Interventions
10 sessions per week of resistance training
Full-body resistance training consisting of 10 sets per week for all major muscle groups with progressive overload in a gym-based setting. Training at an exercise frequency of 10 brief sessions per week (around 8-12 minutes per session).
Two sessions per week of resistance training
Full-body resistance training consisting of 10 sets per week for all major muscle groups with progressive overload in a gym-based setting. Training at an exercise frequency of two sessions per week (around 45-60 minutes per session).
