Grip strength is a measurement of an amount of force a person can exert using the muscles in the hands and forearms. Grip strength is a useful indicator of overall vitality because grip strength is correlated with various health outcome, including heart health and the ability to maintain independence during old age. Many studies indicates that grip strength is a strong predictor of all-cause mortality, and grip strength can be used as a personal benchmark to assess physical health.
Grip strength level change as a person ages, and grip strength typically reaches a peak during a persons late twenties or thirties. During adolescence, grip strength increases rapid because a person’s body is growing and muscle mass is increasing. After a person reaches there thirties, grip strength begin to decline, and this decline often accelerates after a person reaches age fifty.

Men generaly have more higher grip strength averages than women, and the difference between men and women often widens after puberty because of differences in hormone and muscle mass. You can test your grip strength using a tool called a dynamometer.
To test your grip strength correctly, you must sit upright and keep your elbow at a ninety-degree angle. You should perform three maximum squeeze with each hand, and you must rest for a full minute between each squeeze. You should not perform a warmup before testing, because a warmup can increase your grip strength number and make the test inaccurate.
Because a person use their dominant hand more often for daily tasks, the dominant hand will often produce a higher grip strength score then the non-dominant hand. Clinical cutoffs is used to determine if a person has weak grip strength. The World Health Organization use specific thresholds to signal a risk of frailty or weakness.
For men, the clinical cutoff is approximately twenty-seven kilos, and for women, the clinical cutoff is approximately sixteen kilos. If your grip strength fall below these specific numbers, the low grip strength is a signal that you may need medical intervention or increased physical activity. Many factors influences grip strength, and these factors include occupation, geography, and lifestyle.
