The Claim
Heavy resistance exercise training performed three times per week for 16 weeks increases maximal voluntary contraction strength by 19% and type II muscle fiber cross-sectional area by 14% in healthy older men aged 72±5 years, demonstrating a causal effect on muscle strength and hypertrophy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If older men in their early 70s lift heavy weights three times a week for four months, they’ll get noticeably stronger and their big muscle fibers will grow bigger.
