12-week trial in 161 frail older Chinese adults: more resistance training, more leg strength

Original title: Dose-response effects of resistance training on physical function in frail older Chinese adults: A randomized controlled trial.

Under review. A person has not yet checked this summary against the paper. It is written from the PubMed abstract. Until a person checks it, search engines are asked not to list this page.

What the study found

Points to benefit

More volume and higher intensity gave more leg strength and better 6-minute walk results, in a dose-dependent way. High volume also improved the 30-second sit-to-stand and walk test.

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • •Medium size: 161 people.
  • •Lasted 12 weeks.
  • •Measured other health measures, not death from any cause and healthy aging itself.
  • ✓No competing interests declared.
  • •Summarized from the PubMed abstract only. The full paper may hold details the abstract leaves out.

✓ Strength– Limit• Note

These points come from fixed rules about the type of study, its size and length, what it measured, and who has a stake. Every study on Digestery gets the same rules.
