초록

본 연구에서는 요추강화 운동기기를 이용하여 훈련 전후에 대한 유연성 및 근력 특성분석을 고찰하고, 요추 재활운동으로서 가능성을 검증하고자 한다. 요추관련 상해가 없으며 신체 건강한 성인 남녀 20명이 실험에 참여하였으며 각각 10명씩 대조군과 요추강화 운동을 제공받는 훈련군으로 나누었다. 실험에 사용된 요추강화운동기기는 하이스파인(Hi-Spine, 메디컬사이언스, 한국)이며 운동은 하루 40분씩 주 3일, 총 4주간 실시하였다. 또한 본 연구에서 피험자들은 누운 자세, 앉은 자세, 직립 자세, 전신스트레칭자세 등 총 4가지의 운동자세를 각 10분씩 제공받았다. 운동 전 후 요추의 유연성과 근력변화를 알아보기 위해 매주 1회 체간 굴곡 및 신전, 기초체력평가와 요추관절토크를 측정하였다. 실험 결과 훈련군에서 유연성과 근력이 모두 증진되었다. 요추강화운동기기의 플랫폼이 3차원 회전을 함에 따라 피험자들의 근육들은 자극받으며, 회전 방향과 각도에 따라 근긴장성과 근수축 작용을 유도시켜 유연성 및 요추 근력을 증가시키는 것으로 판단된다. 본 연구는 향후 요추관련 상해자 또는 고령자들의 요추 재활운동 프로그램에 적용될 수 있을 것이다.

In this paper, We investigated the characteristic analysis of flexibility and muscle strength for exercise to verify capacity in rehabilitation exercise of lumbar using lumbar strengthen exercise instrument. We have experiment in 20th years man and woman who are 20 subject with no medical history, we divided subjects into control group with no exercise and training group with lumbar strengthen exercise. We used Hi-Spine(Medicalscience.korea) also, provided exercise 40 minute a day, three days a week and progressed total four weeks. Moreover in our experiment, subjects exercised four postural position as lay down, sit, stand and stretch each ten minute. We measured trunk extension backward, trunk flexion forward, evaluation of based physical fitness and lumbar joint torque. The reults have shown that there more improved all for flexibility, based physical fitness and lumbar joint torque in training group than control group. We indicated that by rotating 3-D axis movement flatform of exercise instrument, muscle spindle in subject have been stimulated and these rotation direction and angle caused muscle tonus and contraction that makes muscle, flexibility and based physical fitness improve more. Our study can be used rehabilitation exercise program to aged people and patient with lumbar injury.
