The Claim

Normal-speed low-intensity resistance training, characterized by 1-second concentric and 1-second eccentric actions with 1-second rests between repetitions, performed twice weekly for 12 weeks, significantly improves strength but has limited hypertrophic effects 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

In plain English

For older adults between 59 and 76 years old, doing gentle strength training twice a week for 12 weeks makes them stronger but doesn't build much muscle size.

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 looked at the exact same exercise routine described in the claim and found it made older adults stronger but didn't add much muscle size, just like the claim says.
