简要总结
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.
详细描述
Participants will come to the lab for 3 sessions, plus two email follow-up questionnaires.
Session 1 (45 minutes)
- Complete a demographic questionnaire
- Self-assess muscle soreness
- Walk on the treadmill to warm-up
- Maximal voluntary contraction on the chest press
- Two sets of eccentric (lowering) bench press at 75% of max
Session 2 (45 minutes)
- Walk on the treadmill to warm up
- Maximal voluntary contraction on the chest press
- Three sets of 10 eccentric contractions at 75% of max
- Repeat the maximal voluntary contraction on the chest press

入选标准
- •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.
排除标准
- •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
结局指标
主要结局
Muscle soreness 1
时间窗: 1 day
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Muscle soreness 2
时间窗: 2 days
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Muscle soreness 3
时间窗: 3 days
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Maximal Voluntary Isometric Contraction Change
时间窗: pre-intervention, immediately after the intervention
Change in MVIC will be used to indicated muscle damage.
