Impact of Augmenting Exercise Intensity vs. Frequency

Impact of Augmenting Exercise Intensity vs. Frequency on Peak Work Rate

The purpose of this study is to compare the impact of augmenting exercise intensity and augmenting exercise frequency on peak work rate. Participants will complete exercise tests and provide 8 skeletal muscle samples following a within-subjects randomized crossover design utilizing single-leg cycling. Both training periods will be 4 weeks long and skeletal muscle biopsies will be collected from both legs before and after each training period. All exercise sessions will be supervised, take place in the investigator's laboratory, and occur on stationary bikes.

Inclusion Criteria:

• Recreational active (<3 hours per week of aerobic exercise)
• Willing to provide skeletal muscle biopsies

Exclusion Criteria:

• Cardiovascular or metabolic disease
• Athletes or individuals exceeding 3 hours per week of aerobic exercise
• Smokers
