Abstract
For the purpose of revealing the influence of unilateral upper limb on the opposite side lower limb, we performed an isometric resistance exercise at the start, the middle and the final positions of right upper limb proprioceptive neuromuscular facilitation (PNF) flexion-abduction-external rotation pattern for 25 healthy male. The extension force of both lower limbs during each exercise for upper limb was measured by hand-held dynamometer. The extension force of left lower limb showed a significantly high value in an isometric resistance exercise to the final position of the right upper limb. The extension force of right lower limb did not show any significant difference between each upper limb position. On the isometric resistance exercise by each right upper limb, every extension force of the left lower limb showed a significantly high value. Isometric resistance exercises of unilateral upper limb flexion-abduction-external rotation pattern may be suitable as a method for muscle strength of the opposite lower limb.
