To prevent or remedy musculoskeletal conditions, the relationship between obesity and thecharacteristics of muscle mass and strength need to be clarified. [Subjects and Methods] Atotal of 259 Japanese males aged 30–64 years were classified into 4 groups according tothe Japanese obesity criteria. Body composition was evaluated, and handgrip strength andknee extensor strength were measured for the upper and lower extremities, respectively.Physical performance was evaluated with a jump test. [Results] Obesity was positivelycorrelated with skeletal muscle mass index, percentage of whole-body fat, and leg musclestrength and negatively correlated with the percentage of muscle mass index, bodyweight-normalized handgrip strength, and knee extensor strength, and the jump testresults. [Conclusion] Weight loss may be a better approach than increasing muscle mass andstrength to improve musculoskeletal conditions in obese adult males.Key words: Obesity, Muscle mass, Muscle strength |
