Grip Strength And Mortality

The Study
In this interesting study, 403,199 members of the UK Biobank Study had their grip strength measured and were followed for 7 years. After controlling for all known confounders, including body mass index, men with the highest grip strength had a 32% lower risk of mortality compared to men with the lowest grip strength. Women with the highest grip strength had a 25% lower risk of mortality compared to women with the lowest grip strength. The American Journal of Clinical Nutrition 2017;106:773-82.

Take Home Message
Grip strength is a pretty good indicator of total strength. This study shows us that the stronger you are, the healthier you are. A possible mechanism at play here is improved glucose metabolism and insulin sensitivity in subjects who regularly lift weights. There is also evidence that weight lifters have improved blood lipid profiles. Resistance training is an often overlooked aspect of health and fitness.  Try to hit the weights at least twice a week and preferably three times a week.  You don’t have to lift heavy weights or spend a lot of time, a simple 20-30 minute full body workout with lighter weights will get the job done nicely.
