Abstract: Head teacher are the key in school educations and they carry out their rights and obligations to students on behalf of the schools. But the previous related researches seldom focus on their sports ability, letting alone their influences on students in terms of their sports. Experimental approach is adopted in the paper to research the 4 classes(215 students) of senior 1. The head teachers are made to influence their students in out-of-class sports exercises and class activities in order to explore the intervention effect of the head teachers on the students’ KAP of sports and health and physical fitness. The research result shows that the head teachers’ mastery of sports ability, knowledge structure and their intervention by means of theme class meetings will help promote students in their sports and health knowledge, beliefs, behaviors and physical fitness. What is more, the intervention effect has nothing to do with the gender of the teachers and the head teachers of different genders should show no significant differences in their mastery of sports skills and knowledge structure.

Key words: students, sports and health, physical qualities, experimental research
