The Claim

In older women, increases in lower limb muscular strength and muscle quality following 8 weeks of resistance training are associated with faster walking speed, whereas changes in skeletal muscle mass and body fat are not associated with walking speed.

Source: The improvement in walking speed induced by resistance training is associated with increased muscular strength but not skeletal muscle mass in older women

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

When older women do strength training for 8 weeks, they tend to walk faster if their leg muscles get stronger or work better—but not if they just gain muscle mass or lose fat.

What the research says

1 study

  1. Study: The improvement in walking speed induced by resistance training is associated with increased muscular strength but not skeletal muscle mass in older women

    After 8 weeks of strength training, older women walked faster because their muscles got stronger and worked more efficiently—not because they gained more muscle or lost fat.
