The purpose of this observational study is to examine whether differences in muscle strength between the dominant and non-dominant sides of the body are associated with sarcopenia in older adults. The study will include adults aged 65 years and older with and without sarcopenia. Muscle strength will be measured on both sides of the body using handgrip strength as well as strength measurements of the biceps (upper arm muscle) and quadriceps (thigh muscle). The difference in strength between the dominant and non-dominant sides will be calculated and compared between participants with sarcopenia and those without sarcopenia.
The main question it aims to answers are:
* Do older adults with sarcopenia have larger differences in muscle strength between the two sides of the body compared with those without sarcopenia? * Can differences in arm and leg muscle strength help identify older adults who may be at higher risk of sarcopenia?
