Most comments highlight that despite large hormonal differences, such as testosterone levels, muscle protein synthesis is similar in men and women. The tone is supportive and analytical, with references to specific research findings like the equal responses observed in both sexes, reinforcing the idea that hormonal surges do not significantly alter muscle growth responses in the fed state.
AgreementStrong agreement
Most discussions agree that the study findings show similar muscle protein synthesis responses between men and women, regardless of hormonal differences.
InterestModerate interest
The discussions demonstrate some interest, especially among fitness communities, but mostly focus on confirming the study's conclusions rather than exploring broader implications.
EngagementModerate engagement
Participants engage moderately by referencing research details and related studies, but few delve deeply into methodological critiques or long-term impacts.
ImpactModerate impact
The discussions are respectful and contribute to a better understanding of sex differences in muscle responses, but they do not indicate substantial change in existing views or practices.
Abstract in brief
The study compared how men and women respond to resistance exercise in terms of muscle protein synthesis (MPS) and signaling pathways, revealing that despite men having a much larger increase in testosterone levels after exercise, both sexes had similar increases in MPS.
Men showed greater activation of certain muscle growth signals, like mTOR phosphorylation, shortly after exercise, but overall, there were only minor differences between sexes in the cellular responses related to muscle growth.
These findings suggest that in the fed state, the rise in testosterone after resistance exercise doesn't significantly impact muscle protein synthesis, and both men and women have comparable muscle growth responses despite differences in hormonal and signaling responses.]
The muscle protein synthetic response to exercise and protein ingestion is similar between men and women despite large differences in testosterone levels.

2/ Post‐exercise protein ingestion stimulates muscle protein synthesis equally in men and women.
West et al. saw identical 1–5 h and 24–28 h fed-MPS responses despite a 45× higher testosterone rise in men.
