Handgrip Strength Asymmetry and Weakness Are Associated With Future Morbidity Accumulation in Americans

Klawitter, L, Vincent, BM, Choi, BJ, Smith, J, Hammer, KD, Jurivich, DA, Dahl, LJ, and McGrath, R. Handgrip strength asymmetry and weakness are associated with future morbidity accumulation in americans. J Strength Cond Res 36(1): 106-112, 2022-Identifying strength asymmetries in physically deconditioned populations may help in screening and treating persons at risk for morbidities linked to muscle dysfunction. Our investigation sought to examine the associations between handgrip strength (HGS) asymmetry and weakness on accumulating morbidities in aging Americans. The analytic sample included 18,506 Americans aged ≥50 years from the 2006-2016 Health and Retirement Study. Handgrip strength was measured on each hand with a handgrip dynamometer, and persons with an imbalance in strength >10% between hands had HGS asymmetry. Men with HGS
