Hypothesis
Submaximal control and explosive strength may better detect cognitive impairment than maximal strength.
Conclusion
Submaximal control is poorer in older adults with cognitive impairment compared to those without.
Supporting Evidence
- Submaximal control was significantly poorer in persons with cognitive impairment compared to those that were cognitively intact.
- Similar differences for submaximal control were observed in females with cognitive impairment compared to females without.
- RFD was significantly lower in males with cognitive impairment relative to males without.
Takeaway
Older people with memory problems may not be able to control their muscle strength as well as those who don't have these problems.
Methodology
Participants used an electronic handgrip dynamometer to assess muscle function and cognitive impairment was evaluated using the Saint Louis University Mental Status exam.
Participant Demographics
Adults aged ≥65 years, with a mean age of 70.83 years, 66.4% female.
