德国体育教学法专家海克尔教授在评价体育课的质量时提出了这样的标准:一是出汗,二是笑。他认为,上体育课,学生要从事各种身体活动,体内产热比安静时高出5倍～15倍。为了维持正常体温,绝大部分的热量要通过皮肤蒸发汗液。因此,出汗与否,出汗多少,是学生运动量大小的标志之一。 Professor Haeckel, a German sports pedagogy expert, put forward such criteria when evaluating the quality of PE lessons: one is sweating, the other is laughter. He believes that physical education, students should engage in a variety of physical activity, the body heat than quiescent 5 times to 15 times. In order to maintain normal body temperature, most of the heat to sweat through the skin sweat. Therefore, sweating or not, how much sweating, is one of the hallmarks of the amount of student movement.
