A Study of Comfortable and Warm Supplementary Gear for the Aged People -The Practical Use of Leg Warming Supplewmentary Gear (Leg Warmer) and It's Evaluation-

1.目的研究穿袜子对女性在26℃温度下休息和轻度运动时体温调节反应的影响，因为足部在散热机制中起着重要的作用，因此穿袜子可能会影响足部的体温调节反应。据我们所知，关于袜子与体温调节反应之间关系的研究还有待系统的研究。材料与方法4名年龄19 ~ 20岁的健康女大学生自愿作为研究对象。平均身高156.(]SY.+- . [)3.9 cm，平均体重47.5(]SY.+- . [)3.5 kg，平均体表面积1.41(]SY.+- . [)0.09 m<@D12@>D1。实验在月经周期的卵泡期进行。他们穿着长袖t恤、半长裤和短裤（分别是100%纯棉的）。使用100%安哥拉羊毛编织的袜子（条件A）。不穿袜子作为对照（条件B）。测量的生理参数有直肠温度、皮肤温度、心率和衣物微气候温度。进行两次20分钟的休息，然后进行20分钟的运动，最后进行40分钟的恢复。实验室温为26.0℃，相对湿度为50%。结果与讨论实验结果表明，a样品在40 min的恢复周期内直肠温度明显降低；在整个实验过程中，样品A的腿部皮肤温度保持在显著较高的水平，而样品A和样品b的腿部皮肤被衣服覆盖。样品A的大腿和手掌皮肤温度也保持在显著高于样品b的水平。样品A的四肢皮肤温度较高，可能是加速四肢干热流失的原因样品A中的周围空气，导致岩心温度降低。我们的研究结果表明，在中性环境温度下，久坐和轻度运动的受试者穿袜子可能有助于防止核心温度的升高。少

1.PurposeWe studied the effects of wearing socks on thermoregulatory responses in resting and lightly exercising women at 26ﾟC, because as feet could play a significant role for heat dissipating mechanisms, it might probably influence thermoregulatory responses to cover feet with socks. As far as we know, the studies on relationship between socks and thermoregulatory responses remain to be studied systematically.2.Materials and MethodsFour healthy female students, aged 19-20 yrs, volunteered as subjects. Their mean height was 156.(]SY.+-。[)3.9 cm, mean body mass 47.5(]SY.+-。[)3.5 kg and mean body surface area 1.41(]SY.+-。[)0.09 m<@D12@>D1. The experiments were carried out at follicular phase of the menstrual cycle. They wore long-sleeved T-shirts, half-length pants and shorts (100% cotton, respectively). Socks knitted out of 100% angora wool were used (condition A). Socks were not worn as control (condition B). Physiological parameters for measurements were rectal and skin tempe-rature … More s. heart rate and clothing microclimate temperature. Two 20 min periods of rest followed by 20 min exercise, and final 40 min recovery periods were performed. Experimental room temperature and a relative humidity were 26.0ﾟC and 50%.3.Results and DiscussionAs a result of the experiments, the rectal temperature was kept lower significantly in sample A during 40 min recovery periods, suggesting that heat dissipating mechanisms occurred more effectively in sample A.The leg skin temperature was kept higher significantly in sample A mostly throughout the experimental pe the leg skin was uncovered by clothing in sample A and sample B.Thigh and palm skin temperatures were also kept higher significantly in sample A than in sample B.These higher skin temperatures of the extremities in sample A might be prebably responsible for acceleration of dry heat loss from the extremities to surrounding air in sample A,resulting in reduced core temperature.Our results suggest that it might help the increase of core temperature be prevented to cover the feet with socks in the sedentary and lightky exercising subjects under neutral ambient temperature.
