Your hand strength might be an indicator of your risk for cardiovascular problems.
According to a 2015 study published in The Lancet, grip strength is better than blood pressure at predicting your probability of heart-health problems.
Over four years, researchers at Ontario’s McMaster University tracked 140,000 people aged 35 to 70 living in 17 countries and found that weak hand-grip strength was a red flag for poor heart health.
Using a hand dynamometer for testing, researchers discovered that for each 11-pound decrease in grip strength, individuals had a 17 percent greater risk of cardiovascular death, 9 percent greater risk of stroke, and 7 percent greater risk of heart attack.
“Even after accounting for factors such as nutrition, physical-activity levels, and other medical conditions, hand-grip strength remains an important predictor of the risk of death and cardiovascular disease,” says Darryl Leong, PhD, assistant professor of medicine.
Leong believes grip strength is simply a reflection of overall strength, so he recommends “general exercise — not only restricted to the grip! — that includes both aerobic and strength training.”
