The Claim

Low-intensity resistance training with slow movement and tonic force generation (3-second eccentric, 3-second concentric, and 1-second isometric actions with no rest between repetitions) performed twice weekly for 12 weeks significantly improves isometric knee flexion strength in older adults aged 59-76 years.

Source: Increased muscle size and strength from slow-movement, low-intensity resistance exercise and tonic force generation.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Doing gentle strength exercises slowly and steadily twice a week for 12 weeks makes older adults' knee muscles stronger.

What the research says

1 study
  1. Study: Increased muscle size and strength from slow-movement, low-intensity resistance exercise and tonic force generation.

    The study used the same slow exercise method on older adults and found it really did make their leg muscles stronger, just like the claim said.
