Background and objectives
Sarcopenia and metabolic syndrome (MetS) increase incidence with age. This study evaluated the prevalence of MetS in middle-age to elderly men according to knee and grip strength and muscle mass. Methods
Data from 256 males aged 40–69 years were analyzed. The impedance method was used to assess appendicular skeletal muscle mass (ASM). Muscle strength was measured grip strength with a dynamometer and 60°/s knee strength with isokinetic machine. Strength and muscle mass were divided into quartiles, and logistic regression analyses were performed.
Absolute strength was not significantly prevalent in MetS, but MetS prevalence was significantly higher in participants with lower relative strength and muscle mass values (p<0.05). The group with the lowest relative ASM showed a 3.604-fold increase in MetS prevalence compared to highest ASM. Lowest relative knee extension strength group increased by 3.308 (95% CI 1.201–8.064) and relative knee flexion strength increased by 2.390 (95% CI 1.006–5.560) in MetS prevalence compared to the highest strength group. Lowest muscle mass and extension strength group increased by 6.8-fold com-pared to the highest muscle mass and strength group.
Relative values of strength and muscle mass divided by body weight were significantly associated with MetS. Therefore, having high muscle strength and muscle mass along with low body weight will prevent MetS.
