Description

Kin-Com 3 machine was used to measure trunk strength in 174 normal subjects 71 males, 74 females. Both extension and flexion stops were set at 30°. Testing was performed three reciprocal repetitions at 10° and 30°/second isokinetic speed. The study showed that male had 1.6-1.8 times as large as female at the average torque and the peak torque. The trunk muscles were stronger at 10°/sec than 30°/sec. The average torque of males was decreased with ages in the extensor and flexor. The average torque of females was decreased at random in the extensor, and was decreased with ages in the flexor. The ratio of extensors to flexors was greater in the males than in the females. The ratio of extensors to flexors was greater with ages. The trunk muscle strengthwas different among individuals. The trunk muscle strength was different in different ages, sex, and individuals, but the ratio of extensors to flexors was almost fixed. We considered to analyze at this ratio as an index.
