摘要：

背景：能量代谢是健身、减重、行军、假肢评定、医疗诊断等比较关注的热点之一。康复师与健身教练根据具体情况以及不同目的选择不同的运动方式、运动量与运动强度，有关同等运动速度不同走跑步态模式的能量消耗差异研究较少。
目的：探讨相同运动速度两种步态模式下走跑步态特征以及能耗差异，为大众健身以及运动处方的制定提供理论支持。
方法：受试者为男性健康大学生志愿者20名，使用H/P/COSMOS Gaitway跑台控制走跑运动的速度，测量走跑的步频和步长，使用气体成分分析仪VO2000间接测试人体的能量代谢。在人体第一骶椎放置两维加速度传感器采集前后方向以及垂直方向的加速度原始信号。
结果与结论：相同速度跑模式的步频明显高于走模式下的步频。随着速度的递增，行走主要依靠步频的增加，而跑动时主要依靠步长加大来维持速度。同等速度下跑的能耗明显高于行走的能耗。相同速度下跑明显大于走的人体质心垂直方向加速度均方根值。建议根据不同目的选择不同的步态模式，如需要减重健身时可选择跑模式，而在长距离行军时为了节省能量可以选择快走模式。

Abstract:

BACKGROUND: Energy metabolism is one of the focuses of fitness, weight loss, marching, prosthetic assessment, and medical diagnosis. Rehabilitators and fitness instructors specify movement patterns, amount of exercise and exercise intensity according to the specific conditions and different purposes. Research of energy consumption differences between different movement patterns at the same velocity is less.
OBJECTIVE: To explore gait characteristics and energy consumption differences between two gait patterns of walking and running at the same velocity, providing theoretical support for the public health and the formulation of exercise prescription.
METHODS: The subjects were 20 healthy male college student volunteers. H/P/COSMOS Gaitway treadmill controlled the speed of walking and running. Gas composition analysis instrument VO2000 was used indirectly to test the body's energy expenditure. Tow-dimensional acceleration sensor was placed on the first sacral vertebra to collect anteroposterior and vertical original signals of acceleration.
RESULTS AND CONCLUSION: Step frequency of running pattern was significantly higher that of walking pattern at the same speed. With the speed increments, walking mainly relied on the increase in the step frequency, but running mainly depended on the step length increase to maintain the velocity. The energy expenditure of running was significantly higher than that of walking at the same speed. When running, the root mean square of the centre of mass vertical acceleration was significantly greater than that when walking at the same speed. It is suggested to choose different gait patterns according to different purposes, such as, select the running pattern such as weight loss fitness, and select fast walking pattern in order to economize energy in the long-distance march.
