Protein Ingestion Timing on Body Composition and Biochemical Markers in Resistance-trained Males

Comparison of Protein Ingestion Timing on Body Composition, Physical Performance, and Biochemical Markers in Resistance-trained Males

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 40 (actual)
• Sponsor: Marymount University · Academic / Other
• Sex: Male
• Age: 18 Years – 35 Years
• Healthy volunteers: Accepted

Summary

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

Conditions

• Hypertrophy
• Physical Performance

Interventions

Type	Name	Description
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.
DIETARY_SUPPLEMENT	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.
