几种生化指标( C K、 B U N、 H B、 L A、尿蛋白和隐血、尿 P H、胆红素和尿胆原、尿肌酐) 在运动实践中的应用 总被引:3,自引:0,他引:3
在当前国际竞技水平不断提高的形势下, 千分之一秒的胜负都需要运动员付出极大的生理代价, 这就更加要求以科学合理的手段最大限度地挖掘人类的运动能力, 有目的地进行科学训练。下面就一些比较常用的生化指标的特性及其在运动实践中的应用作一综述。如对训练的适应, 机能状态的评定, 实际应用方法等, 使运动训练更具科学性。本理论对教练员和运动员有一定的参考意义。 相似文献

In this article, we examine philosophy of sport as a field of study in Japan, its history, characteristics, and future prospects, as part of a contribution to the international development of the discipline of sport philosophy. The Japan Society for the Philosophy of Sport and Physical Education has been holding an annual sport philosophy conference every year since its inception in 1978. Nevertheless, the trends of sport philosophy in Japan have not been conveyed abroad. The language barrier between Japanese and English as an international communication tool makes it difficult to spread our work on the philosophy of sport throughout the world. The question arises as to whether the philosophy of sport in Japan has the same trends as those in the Western countries. Is it reasonable to assume that it has different aspects and interests than philosophy of sport in English-speaking countries? We will also try to address these questions for our audience 相似文献

Abstract This study recorded the age, height, weight, and grip strength of 299 healthy adult males, representing college students newly enrolled in a body conditioning class, college athletes, recruit policemen and policemen. Analysis of the data showed that for men in condition and within the limits of the study, grip strength is significantly related to weight but not to height or age. 相似文献

运动即变化,太极即变化。太极拳即变化之拳。太极拳运动就是要把种种变化在拳中演练出来。太极拳以拳为形式,其目的在于要达到“太极”状态。拳是小“道”,“太极”是大“道”,习拳明理,以小“道”通大“道”,是太极拳最重要的意义。变化即是太极、太极拳最根本的意义。误解了太极拳“变化”的真意,只会将太极拳引入歧途。 相似文献

Abstract Subject performed a five-choice reaction time (RT) and movement time (MT) task while walking on a treadmill at heart rates (HR) of approximately 80 (standing still), 115, 145 and 175 beats per minute (bpm). Five-choice RT was optimal at a HR of 115 bpm and worst at 175 bpm, thereby supporting the hypothesis of an inverted U relationship between activation and choice RT. On the other hand, MT improved linearly with increased levels of HR, showing that these two parameters are affected quite differently by concomitant physical exertion. 相似文献

In this article, I will examine a difficult subject in competitive sports: loss and defeat. Defeat is painful because we do not enter into competitive games to be defeated, although defeat is a strong possible outcome of the game, especially among more or less equal contestants. If losing a game is an existential condition that lies ahead of every athlete and team, even the best ones, why is defeat difficult to accept, especially in modern times in contrast to ancient times? I will explore recent studies and ideas on sacrifice, especially those of Bataille, and discuss Heidegger’s notion of being-toward-death within the context of defeat in sports. Every defeat presupposes a form of sacrifice, understood in the loose sense, and every sacrifice presupposes a certain disposition toward death. Not only is defeat an inevitable condition in sport-making, but it is intrinsically linked to regimes of victory. Nietzsche acknowledges this intrinsic connection between defeat and victory. I will detour into this area to show that Nietzsche’s agonistics does not dismiss the necessity of loss, defeat, sacrifice, and death in competition; on the contrary, and this may not be obvious to modern readers, he sees them as necessary in the practices of self-transformation toward higher goals and states. 相似文献

Abstract The incidence of orthopedic problems was examined in 5, 582 men and women who attended the Cooper Clinic in Dallas, Texas between 1974 and 1982. The effects of age, physical activity, physical fitness, and body mass index (EMI) on the occurrence of these problems were examined using a proportional hazards approach. The expected risk of orthopedic problems per person-year was 0.045 for men and 0.046 for women. For men, physical fitness, BMI, and physical activity were associated with orthopedic problems, while for women, physical activity was the main predictor. Age was not a factor for either gender. The effect of change in physical fitness, physical activity, and BMI was examined in a subset of 2, 325 persons with more than one visit to the clinic. For women, physical activity and a decrease in BMI were associated with orthopedic problems, while for men none of those factors were significant. Again, age was not a factor in either group. The absence of any age effect on the occurrence of problems suggests that with regard to orthopedic problems, moderate amounts of physical activity in generally healthy persons may be recommended without special consideration as to age. 相似文献
