About this trial
The purpose of this study will be to test whether a new way of weight training is more effective than typical weight training. The investigators expect that this new way will cause more exercise-induced muscle damage, which helps people build bigger muscles. Another purpose of this study will be to explore perceptions of how muscle soreness impacts participant activities of daily living.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Sixteen young adults (ages 18-35) will be enrolled in this study.
In order to be enrolled, they must have completed at least three months of resistance training in the past five years in order to minimize the learning effect and chance of injury.
Disqualifiers
Since regular resistance training reduces the primary outcomes, muscle damage and soreness, individuals who currently participate in chest press resistance training at least once per week will be excluded.
Individuals who have musculoskeletal injuries in the shoulder, elbow or wrist that preclude pain-free resistance training, or who have underlying uncontrolled cardiovascular complications will also be excluded.
Women who are pregnant, or may consider becoming pregnant over the subsequent 2 months, will be excluded
