A number of studies have come out recently showing that grip strength is a dependable predictor of overall health and wellness. This is likely no surprise to long-time advocates of the iron but it signifies a big step in the right direction for the traditional medical community.
Studies have associated grip strength with:
“Each 11-pound decrease in grip strength over the course of the study was linked to a 16% higher risk of dying from any cause, a 17% higher risk of dying from heart disease, a 9% higher risk of stroke, and a 7% higher risk of heart attack.”
That’s pretty damn convincing. What’s even more shocking is that the study concluded:
“Grip strength was a stronger predictor of all-cause and cardiovascular mortality than systolic blood pressure.”
Whoa, talk about rocking the boat! Blood pressure has been the most frequently utilized measure of CVD risk for over 100 years. Maybe next time you visit the Doc they should be pulling out the dynamometer instead of the sphygmomanometer!
Now it’s important to recognize something here.
It’s not the grip itself that is the proposed mechanism for improving health outcomes. Grip strength is a signifier of overall vitality and robustness. I think you would be misguided to go out and buy the Captains Of Crush grip trainer in an effort improve your health. (Although I think these are freaking awesome and I believe they have utility elsewhere.)
People who lift weights are generally healthier overall and make better lifestyle choices than those who do not. A natural side effect of participating in weight lifting is an increase in grip strength especially with exercises like chin-ups, deadlifts and carries. Additionally, we know that graded, progressive exercise builds stronger and more resilient humans especially as we age.
A study looking at the effect of strength training and aerobic exercise on inflammatory gene expression in elderly populations demonstrated that key inflammatory biomarkers IL-6, TLR4 and TNF-alpha all dropped significantly in response to exercise intervention.6
So if strength training is the medicine, what is the prescription?
Trade in machine-based training and “toning” routines for free weights. The key to developing resiliency through weight training is to lift weights that are progressively challenging and to choose exercises that require you to stabilize your torso against a load.
If you are new to the weight room hire a coach in your area who is an expert or look into online training with a qualified professional. You wouldn’t take a prescription medication without advisement from your doctor would you?
Strength training is simple but not easy and physical vitality is built with good old fashion hard work and heavy lifting. Next time you hit the gym pick up something heavy and put it back down then carry it and squat it, you might just live longer.
