简要总结
This study will assess the effect of daily post-exercise vegan (pea) and animal (whey) protein ingestion compared to placebo over 7 days of recovery from strenuous exercise. Muscle strength and soreness will be measured daily, and mechanisms underpinning recovery will be investigated in muscle biopsies taken 3, 24 and 48 hours after exercise.
详细描述
Strenuous exercise can cause muscle soreness and reduced muscle strength. It is widely acknowledged that nutritional supplements derived from animal protein sources, including whey from milk, aids recovery when taken immediately after strenuous exercise. However, the effect of vegan protein supplements are less understood, and how they affect recovery of strength and soreness is not known. This is an important area of research due to the increasing demand for plant-based protein.
