The purpose of the present study was to compare isokinetic muscle strength of shoulder, hip, knee and trunk at varying speed between elite and student in kendo and normal subjects. Subjects were 7 elite in all Japan kendo championship whose average age was 36.1±4.3 years and 6 student kendo player whose average age was 20.2±0.4 years and 20 normal whose average age was 35.3±2.8 years. An isokinetic dynamometer (Cybex II) was used to measure the peak torque generated during shoulder extension &flexion, shoulder internal & external rotation, hip extension & flexion, hip abduction & adduction and knee extension & flexion at three different speed (60,180,240°/sec.). And the trunk extension flexion unit was use to measure the peak torque generated during trunk extension & flexion at three different speed (60,120,150°/sec.). These result were obtained: I) Eite kendo players were superior in isokinetic strength of shoulder extension, shoulder external rotation, hip extension and hip adduction at these condition,2)nevertheless elite and control group of knee extension & flexion was not significant.3) In the ratio of. antagonist to agonist on upper and lower limb, elite kendo players were superior in extension/flexion of both shoulder, extension/flexion of hip of right side internal/external rotation of both hip.The ratio of knee extension /flexion in elite was higher in only 180°/sec. of right side and 240°/sec. of left side than control. Elite on extension/flexion ratio of trunk was not significant.
These results suggested that developments of strength of elite kendo player were specifically different the agonist and antagonist muscle group by kendo training.
