In this study, the relationship between the gait condition and foot temperature distributions inside footwear was investigated using subject experiments. Mechanical, physical, and physiological variables such as the foot contact force, landing speed, and metabolic heat generation were also measured. Gait motion measurements showed that a large contact force was concentrated in the small area of the heel at the initial contact and later at the forefoot. A faster gait produced a larger contact force, higher landing velocity, higher skin temperature, and larger metabolism during gait. The temperature at the bottom of the foot increased, and the temperature on the upper side decreased. The metabolic heat generation had a basic impact on the temperature profile, and skin temperatures tended to increase gradually. In addition, high-temperature-elevation regions such as the big toe and heel coincided with regions with high-contact loads, which suggested a relationship between the temperature elevation and contact load.
在本研究中，通过受试者实验研究了步态状况与鞋内足部温度分布之间的关系。还测量了诸如足部接触力、着地速度和代谢产热等机械、物理和生理变量。步态运动测量表明，在初始接触时，较大的接触力集中在脚跟的小区域，随后集中在前脚掌。较快的步态在步态过程中会产生更大的接触力、更高的着地速度、更高的皮肤温度和更大的代谢率。脚底温度升高，而上侧温度降低。代谢产热对温度分布有基本影响，皮肤温度往往会逐渐升高。此外，诸如大脚趾和脚跟等高温度升高区域与高接触负荷区域重合，这表明温度升高与接触负荷之间存在关联。
