Sample Answer
The handgrip dynamometer test
- Provides an efficient and objective measure of upper body strength that correlates with overall functional capacity and has been shown to predict future disability in aging populations.
- This strength assessment requires minimal participant exertion or skill, making it accessible across diverse populations including those with limited exercise experience, unlike more complex strength tests.
- Limitations of the handgrip test include its focus on only one aspect of muscular strength, potentially overlooking lower body strength deficits that may be critical for daily functioning and mobility.
Skin fold caliper measurements
- Offer a more accurate assessment of body composition than BMI alone, which can misclassify muscular individuals as overweight or obese.
- The caliper method is relatively inexpensive compared to more advanced body composition techniques like DEXA scans, making it cost-effective for community-wide implementation.
- Significant limitations of skin fold measurements include potential embarrassment for participants during measurement, requiring private testing areas and sensitive administration to maintain psychological safety.
