In a large cohort study of adult patients with no diabetes at baseline, a moderate level of muscular strength was associated with a lower risk of type 2 diabetes (T2D), independent of estimated cardiorespiratory fitness (CRF). A total of 4,681 adults aged 20‒100 years underwent muscular strength tests and maximal treadmill exercise tests between January 1, 1981, and December 31, 2006. Among the findings:
- During a mean follow-up of 8.3 years, 229 of 4,681 participants (4.9%) had development of T2D.
- Those with the middle level of muscular strength had a 32% lower risk of development of T2D compared with those with the lower level of muscular strength.
- There was no significant association between the upper level of muscular strength and incident T2D.
