采用文献资料、专家访谈、录像观察等研究方法，对2019年男篮世界杯中国队在比赛中罚球进行了分析，并且从整体上，到球员不同位置上和本届比赛的前三名的罚球相关数据进行了研究。结果表明，中国队罚球命中率低，不能很好的把握罚球得分的机会，与世界强队（P<0.05）存在明显差异，是严重制约比赛成绩的重要因素；同时针对提高罚球命中率的方法和策略，提出了相应的措施和建议，旨在为中国篮球罚球的训练和比赛提供一定的借鉴和参考。

Effects of Eight Weeks of Head Down 'Tilt Strong Abdominal Breathing Training on Cardiac Function of Female College Students

Using methods of literature research, expert interviews, and video observations, we analyze free throws given to Chinese team in the games of 2019 Men''s Basketball World Cup. Data on free throws by top three players in the competition-Spain, Argentina, French, and overall free throws and those in different positions are studied. It is found that Chinese team has the lowest free throw hit rate and lose the chance to score free throws in many cases. There are obvious gaps between world''s top teams (P<0.05) and Chinese team. As a result, China''s performance is unsatisfactory. With respect to methods and strategies for improving Chinese team''s hit rate of free throws, we offer targeted measures and suggestions, which can be helpful to Chinese team in their trainings and competitions in free throws.
