Grip strength is associated with a range of health outcomes, from type 2 diabetes to depression.
In a world of technologically-driven longevity clinics with their increasingly sophisticated imaging scans, some of which can cost tens of thousands of dollars, it turns out that one of the best assessments of muscle strength and quality is to simply sit in a chair and squeeze a tennis ball.
When testing grip strength in clinical trials, scientists typically use a hand dynamometer, a device which you squeeze as hard as possible to measure the force generated by the muscles in your hand and forearm. Several companies are now attempting to take the dynamometer out of the clinic and into the home, combining easy-to-use devices with mobile apps to let anyone chart their grip strength over time.
