Clinical Trial Summary

Protein ingestion timing is an important component for muscle accretion. We hypothesized that protein ingestion timing could affect muscular adaptations and performance in resistance-trained men.

• not taking any steroids or any illegal agents known to increase muscle size for at least 1 year prior to the start of the study
• no known medical issues
• sleeping for at least seven to eight hours during the 24-hour day

Exclusion Criteria:

• Physical Performance

Intervention

Dietary Supplement:
• isolate whey protein prior to and immediately after resistance training
This arm involved protein ingestion immediately prior to and immediately after resistance training for 12 weeks. Participants will consume 40 g of isolate whey protein at their recommended timing.
• isolate whey protein 3 hours prior to and 3 hours after resistance training
This arm involved protein ingestion 3 hours prior to and 3 hours after resistance training for 12 weeks. Participants will consume 40 g of isolate whey protein at their recommended timing.
