Question:I had a fitness test at my doctor's office. They used a test of my grip strength to determine my overall strength. Is this an adequate test? I don't see how my grip strength tells anything about how strong my arms are.
Studies dating back to the early 1950s show a link between grip strength and overall arm strength. For most people handgrip strength shows a moderate correlation with the total strength of many other muscles of the body. If the grip is strong, the shoulders are also strong.
Handgrip strength is used as a measure of overall strength for several other reasons. It's safe and easy to measure using a handheld device called a dynamometer. This device is readily available in many health care, school, and gym settings. This makes strength testing using a grip test convenient.Jeffrey E. Budoff, MD.
