Higher knee extension strength is associated with what percent lower risk of all-cause mortality?

Higher knee extension strength is associated with what percent lower risk of all-cause mortality?

• A. 14%
• B. 8%
• C. 22%
• D. 30%

Answer: (A)

The main idea here is that leg muscle strength, especially the knee extensors, is a meaningful predictor of overall health and survival. Stronger knee extensors reflect better muscle mass, mobility, and metabolic reserve, which are linked to lower risk of death from any cause. In the material you’re studying, higher knee extension strength is associated with about a 14% lower risk of all-cause mortality. This reflects a relative risk reduction seen after adjusting for other factors like age, sex, body size, and health conditions. So, increasing knee extensor strength corresponds to a modest but meaningful improvement in longevity risk. Practically, this highlights why resistance training to boost leg strength can have broad health benefits beyond just making activities easier or preventing falls.
