Validity of posterior oblique Walking-Exercise by the use of an fixed Omnidirectional Walking Machine

目的：研制一种固定式全方位步行机，在一般情况下不可能进行后斜行，但利用该机成功地锻炼了老年人的后斜行，探讨了后斜行锻炼的有效性。设计：受试者29人，平均年龄68.8岁(男14，女15)。采用后斜肌步行练习，每周两次，每次2分钟，共19次。在研究开始和结束时，评估肌肉力量(髂腰肌、臀中肌和股四头肌)和五次椅子起立时间。结果：无论右、左斜向训练方向，所有肌力均显著提高(p&lt；0.0007)，5次坐姿起立时间显著改善(p=0.0012)。结论：短时间、短时间后斜行走可使肌肉力量增加，使坐姿上升时间提高5倍。

OBJECTIVES:We developed an fixed Omnidirectional Walking Machine.In general, it was impossible to do posterior oblique walking,but by means of this machine, we were successfully able to exercise the aged in posterior oblique walking.We investigated the validity of posterior oblique Walking-Exercise. DESIGN:Participants were 29persons average aged 68.8years(male14,Female15).Posterior oblique walking exercises were performed once two minutes, twice a week, for a total of 19 exercises. Muscular strength(iliopsoas,gluteus medius,and quadriceps muscle) and five times chair rise time were evaluated at the beginning and the end of this study. RESULTS:Regardless of right or left oblique training direction, all muscular strength increased significantly (p<0.0007), and five times chair rise time improved significantly(p=0.0012). CONCLUSION:Posterior oblique walking in a short time and in a short period has brought about increase of muscular strength and improvement on five times chair rise time.
