title: The influence of a physical ability intervention program on improved running time and increased sport motivation among Jerusalem schoolchildren.
abstract: Several studies have demonstrated an inverse relationship between physical activity and coronary heart disease (CHD). Other studies have reported a negative correlation between aerobic capacity and obesity and CHD risk factors among adolescents. In this study, the possibility of modifying physical ability in adolescents aged 13 has been examined through a physical ability intervention program. During 1984-1985, all eligible eighth graders from five Jerusalem public schools participated in the program. Physical ability was defined in the biological dimension by the running time for 1000 meters, and in the psychological dimension by sport motivation. The intervention program involved a periodic and progressive increase of physical effort of children in 16 gym lessons during the regular curriculum. The major findings were that the test group improved their running time and had better sport motivation than did the control group, and there were differences between boys and girls and an influence of sexual maturation on running time in girls.
