The characteristics of asymmetry in muscle strength of female college students are still unknown. This study aims to evaluate of characteristics of asymmetry in muscle strength. Both methods of isometric and isokinetic maximal muscle strengths of elbow and knee joints were measured in fortyfour female college students. In dominant/nondominant difference, isometric maximal muscle strength and isokinetic muscle endurance of dominant in the flexion of elbow joint were approximately 9% and 14% higher than those of the non-dominant, respectively(p<.05, p<.01), but there was no difference in the knee joints. The dominant/non-dominant ratio(DNDR) of isokinetic muscle endurance strengths in the elbow were approximately 1.2 times higher than those of isometric strengths. In flexion/extension difference, the isometric flexor strength were approximately 17% and 31% higher than those of the extensor strength in the elbow joint, respectively(p<.05, p<.01). In the knee joint, the flexor strengths of all measured muscle were consistently approximately 48~56% lower than those of the extensor strength. There was no significant difference between competition muscle strength ratio(CMSR) of each muscle strengths in the knee. These results suggested that differences of DNDR and CMSR among measured muscle strengths more appear in the elbow than in the knee joint. |
