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 increases thigh muscle thickness 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.

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

In plain English

Gentle weight training done slowly and steadily twice a week for 12 weeks can make older adults' thigh muscles thicker and 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 tested the same exact slow-motion exercise routine in older adults and found it really did make their thigh muscles thicker, just like the claim said.
