简介:通过对大学生进行健身运动处方和常规体育教学两种教学模式的实验对比,探讨和研究大学生体质最优化的教学模式,为推进高校体育课程体系改革和促进大学生健身的科学化提供理论和实践指导方面的依据。本研究按随机抽样原则在柳州医学高等专科学校05级学生中,随机抽取4个班,其中两个班作为实验班,另两个班作为对照班,进行健身运动处方教学和常规体育课教学的对比,实验期为1年,以验证运动处方教学模式对大学生体质影响的效果。结果显示:实验班和对照班在身体素质、身体机能等指标上,存在非常显著性差异。健身运动处方教学模式能有效提高大学生体质健康水平,对增强、改善学生体质有显著效果,具有更强的实效性和科学性,是实现大学生体质最优化的一种有效可行、值得推广的教学模式,符合高校体育课程体系改革发展方向。
