Picture analysis on the horse and rider's movements with respect to the riding for the normal and disabled

众所周知，骑马对正常人和残疾人的健康有更好的影响。采用三维图像分析的方法，从马的比例、腺体状况、有无骑手等方面研究了步行和快步骑马的马肩隆、左、右髋关节和骑手左腰部的运动。马匹各体位垂直运动量大，颈长、四肢长、躯干短、躯干周长小。这一趋势在坚固的大体上行走和小跑比在柔软的大体上更明显。站立阶段的垂直运动大于挥杆阶段。骑手的出现降低了垂直运动的幅度，缩短了步幅。骑手的动作接近马的臀部，这是受后肢运动影响最大的地方。骑手的心率和呼吸频率在步行时增加，在小跑时增加更多。这种反应在健康成年人中比在健康儿童中更明显。

The horseback riding has been known as producing preferable health effects for normal and disabled persons. The movement of the withers, left and right points of hip of the walking and trotting horses and left lumber portion (Os ilius) of rider was studied by the aid of three dimension picture analysis with respect to proportion of horses, gland conditions, the presence or absent of rider. The vertical movement of each position was large in horses with longer neck and limbs, short trunk and smaller circumference of the trunk. This tendency was apparent in walking and trotting on the solid grand more than the soft grand. The vertical movement was larger in the stance stage than in the swing one. The presence of rider diminished the magnitude of the vertical movement and shortened the stride. The movement of the rider was close to that of the point of hip in the horse, where it was most affected by the movement of hind limbs. The heart rate and respiratory rate in rider increased during walking and more during trotting. This response was apparent in healthy adults than in healthy children.
