Summary

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.

Interventions

Type	Name	Description
BEHAVIORAL	Frequency comparison	One leg assigned to low-frequency low-intensity (3 days per week of 11 x 1 min @ 73% peak work rate interspersed with 1-minute periods of active recovery). The other leg assigned to high-frequency low-intensity (5 days per week of 11 x 1 min @ 73% peak work rate interspersed with 1-minute periods of active recovery).
BEHAVIORAL	Intensity comparison	One leg assigned to low-frequency low-intensity (3 days per week of 11 x 1 min @ 73% peak work rate interspersed with 1-minute periods of active recovery). The other leg assigned to low-frequency high-intensity (3 days per week of 8 x 1 min @ 100% peak work rate interspersed with 1-minute periods of active recovery).
