研究组 & 干预措施
Protein ingestion immediately 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.
干预措施: isolate whey protein prior to and immediately after resistance training (Dietary Supplement)
Protein ingestion 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.
干预措施: isolate whey protein 3 hours prior to and 3 hours after resistance training (Dietary Supplement)
