Environmental and cultural aspects are known to influence particular characteristics of an ethnic group and, as such, are partially responsible for distinguishing an ethnic group from others. This study was designed to compare non-athlete young Japanese and American males on a variety of physiological and fitness characteristics in order to locate and quantify the magnitude of any physiological and fitness differences between the two races. Aerobic capacity based upon bicycle ergometer, resting heart rate, and resting blood pressure, vertical jump, grip strength, and flexibility as measured by sit-and-reach, and trunk-and-neck extension tests were obtained for 20 Japanese and 20 American males whose ages ranged between 19 and 25 years. Cardiovascular and aerobic capacity data indicated that the Americans had higher blood pressure (both systolic and diastolic blood pressures) and higher absolute VO2max than the Japanese. However, the Japanese had a higher relative VO2max value than the Americans. The Japanese had higher values than those of the Americans in the vertical jump and for trunk-and-neck flexibility. Within the limitation of the present study, it can be concluded that the Japanese had a higher lower extremity power and better flexibility in the trunk-and-neck extension compared with the American.
已知环境和文化因素会影响一个族群的特定特征，因此，它们在一定程度上导致了一个族群与其他族群的差异。本研究旨在比较日本和美国非运动员年轻男性在各种生理和体能特征方面的差异，以便找出并量化这两个种族之间在生理和体能上的差异程度。对20名年龄在19至25岁之间的日本男性和20名美国男性进行了基于自行车测力计的有氧能力、静息心率、静息血压、垂直纵跳、握力以及通过坐位体前屈和躯干与颈部伸展测试所测量的柔韧性测试。心血管和有氧能力数据表明，美国人的血压（收缩压和舒张压）和绝对最大摄氧量高于日本人。然而，日本人的相对最大摄氧量高于美国人。日本人在垂直纵跳以及躯干与颈部柔韧性方面的值高于美国人。在本研究的局限性范围内，可以得出结论，与美国人相比，日本人的下肢力量更强，躯干与颈部伸展的柔韧性更好。
