Background
• Muscle damage can be evident immediately after exercise and for a number of days following exercise, resulting in a loss of muscle function and muscle soreness
• Whey Protein Hydrolysate (WPH) is pre-digested proteins, recognised as more readily digested and absorbed when compared to intact proteins
• There are greater benefits of WPH over any other form of whey protein to reduce muscle damage, when WPH is taken as a single serving post-exercise or longer-term supplementation strategy
• Science in Sport WHEY20 is an innovative protein product using WPH
Study Aims and Location
• To examine the efficacy of WHEY20 supplementation on markers of muscle recovery following muscle damaging exercise
• This study was completed at The University of Northumbria
Methods
• 20 physically active females participated in the study, split evenly into WHEY20 or carbohydrate (CHO) supplementation groups
• Participants completed a repeated sprint exercise protocol designed to induce muscle damage, followed by twice daily WHEY20 or CHO supplementation for 72 h post-exercise
Results
• WHEY20 significantly improved measures of reactive strength and flexibility 72 h post-exercise when compared to CHO
• Muscle function recovered through the 72 h post-exercise in both groups, this recovery appeared to be accelerated with WHEY20 supplementation
• WHEY20 significantly reduced blood markers of muscle damage at 48 h compared to CHO
Conclusions
1. The inclusion of WHEY20 in the 72 h post-exercise nutrition strategy significantly improves recovery of muscle function, measured by improvements in reactive strength and flexibility
2. The inclusion of WHEY20 in recovery nutrition is beneficial for reducing the symptoms of muscle damage associated with exercise
