The Claim

A 16-week supervised whole-body resistance training program conducted twice weekly results in a statistically significant increase in whole-body lean soft tissue mass (1.46%) among healthy middle-aged Japanese women, demonstrating that regular resistance exercise can enhance muscle mass during midlife.

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.

In plain English

Working out with weights twice a week for four months can help middle-aged Japanese women build a little more muscle, even as they get older.

What the research says

1 study

  1. Study: Relationship between protein intake and resistance training-induced muscle hypertrophy in middle-aged women: A pilot study.

    The study looked at the same type of exercise program described in the claim and found that it really did increase muscle mass in middle-aged women, just like the claim says.
