1. 8名男性日本巴西人和11名男性日本人自愿参加了这项研究。每个人坐在椅子上45分钟，40摄氏度（r.h.）。50%）。然后，他们使用自行车测力计在半卧位进行45分钟的运动，最大摄氧量为40%。热感觉和舒适感证实了巴西日裔人在40摄氏度的环境中比日本人感觉更凉爽和舒适。两组的摄氧量、出汗率和体重减轻量无显著性差异.巴西人的前臂血流量和心率明显低于日本人。巴西人胸部皮肤温度显著高于日本人.因此，在日本巴西人中观察到的体温调节反应可能在很大程度上归因于他们位于南回归线的家乡的气候。这些结果表明，环境条件是决定体温调节反应的重要因素。
1. Eight male Japanese Brazilians and 11 male Japanese volunteered for this study. Each one sat on a chair for 45 min at 40 degrees C (r.h. 50%).2. Then, they exercised using a bicycle ergometer in a semi-reclining position for 45 min at 40% of maximal oxygen uptake.3. Thermal and comfort sensation confirmed that Japanese Brazilians felt cooler and more comfortable in 40 degrees C environment than the Japanese.4. Oxygen uptake, sweat rate and body weight loss for both groups were not significantly different.5. Forearm blood flow and heart rate for Brazilians were significantly lower than those for Japanese.6. Skin temperature at chest region for Brazilians was found to be significantly higher than that for Japanese.7. Thus the thermoregulatory responses observed in Japanese Brazilians may be largely attributed to the climate in their native places located on the Tropic of Capricorn.8. These results may indicate that environment condition is the important factor in determining the thermoregulatory responses.
