The Effects Of Police Sports On The Health-related Fitness Of Police College Students

Police sport is a special form of physical education in our country. It originates from themilitary sports and finally became an independent subject. The study, using such testinginstruments as component analysis, MAX-II Metabolic System, electronic pressuremeasurement instrument, and distance cardio tachometer, investigated60freshmen (40malesand20females) from Jilin Police College. Experimental method, document method,mathematical statistics method, logic induction and expert interview were used in this study.The subjects’ height, weight, chest circumference, waist circumference, hip circumference,waist hip ratio, resting heart rate, vital capacity, maximal oxygen uptake,1000m,800m,systolic pressure, diastolic blood pressure, back strength, left-hand grip strength, right-handgrip strength, push-up, situps, standing long jump, crook before the seat body, lean body mass,fat content, muscle content were measured before college and after their graduation. Thestudy aims at revealing the effects of police sports on the body shape and the health-fitness ofpolice college students and providing some practical and theoretical reference for futurestudies.The major conclusions are listed below:(1) The3-year study of police sports had little effects on the body shape of males such aswaist and hip. However, it had a significant influence on females’ body shape except theirheight.(2) Police sports is able to improve the students’ cardiopulmonary. For instance, there is adecrease in their blood pressure, in heart rate when they were immovable and an increase intheir vital capacity and maximal oxygen uptake of the males and females in the experimentalgroup.(3)The experiment revealed that police sports can enhance the subjects’ muscle-fitness. Thereis a significant increase in the aspect of back strength, the right-handed grip strength, thestanding long jump,1min push-ups and1min sit-ups. However, little effects were showed inthe subjects’ left-handed strength.(4) Police sports can improve the subjects’ pliability-related fitness. For example, the subjects’performance in anterior curvaturein standing body increased significantly.(5)After the3-year participation of police sports, the subjects’ fat content, either males’ orfemales’, decreased, while the females’ weight and the males’ lean body mass, in some degree,increased. However, there was little change in the males’ weight and the females’ lean bodymass. Therefore, police sports have positive effects on the health-related fitness of policecollege students.
