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

Marymount University

Status: Completed

Conditions: Physical Performance; Hypertrophy

Treatments: Dietary Supplement: isolate whey protein prior to and immediately after resistance training; Dietary Supplement: isolate whey protein 3 hours prior to and 3 hours after resistance training

Study type: Interventional

Funder types: Other

Identifiers

NCT05544955

About

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.

Enrollment: 40 patients

Sex: Male

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• performing resistance training at least three times a week for 1 year prior to the start of the study
• 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

• non-willingness to continue protein ingestion or exercise protocols
• participation in exercise other than the prescribed resistance training program
• consumption of dietary supplement (other than the protein intervention) during the study period
• Missing more than one resistance training session or protein ingestion throughout the study period

40 participants in 2 patient groups

Protein ingestion immediately prior to and immediately after resistance training

Experimental group

Description:

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.

Treatment:

Dietary Supplement: isolate whey protein prior to and immediately after resistance training

Protein ingestion 3 hours prior to and 3 hours after resistance training

Experimental group

Description:

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.

Treatment:

Dietary Supplement: isolate whey protein 3 hours prior to and 3 hours after resistance training
