The Effects of Protein Supplementation in Females and Males Following Acute Eccentric Exercise
- Conditions
- Muscle Damage
- Registration Number
- NCT04679519
- Lead Sponsor
- Liverpool John Moores University
- Brief Summary
Examine the impact of the protein supplements leucine, HMB and BCAA on muscle recovery and inflammatory response following acute exercise.
- Detailed Description
Participants, both females and males, will perform an acute bout of exercise. A bout of exercise that will involve multiple drop jumps. Prior to and post exercise, functional outputs will be measured and blood will be collected to quantify the inflammatory response. The protocol will involve attending the laboratory on 6 occasions over a two week period to complete the above measures.
