The Effects of Protein Supplementation in Females and Males Following Acute Eccentric Exercise

Not Applicable
Completed
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.
