Abstract: The study was investigated on 389 Jat boys of Delhi rural population. It was a cross sectional study ranging in age from 10 to 20 years. The subjects were belonged to a single endogamous genetic group of Jat boys of Delhi (rural area). All were studying in educations institutions of Delhi rural areas. For growth pattern and norms of sports motor ability, 30 meters test related to fast running capacity (un-aerobic) was taken for data collection. Descriptive statistical calculation was used for tabulation work. The mean value of the samples depicts the growth patterns of Jat boys in tables. Age wise of 11 groups were made to view the growth and norms to show the motor ability. The study of of Delhi Jat boys has been made on Mean and ‘V’ (velocity) values given in tables. Hence, the comparison of ‘V’ values computed and describes the percentage differences between from age to age. Findings proved the pattern of changes continuous in all ages from 10 to 20 years. Big changes were noticed in the motor ability at the age of 15 years and followed in 13 years. Percentiles were calculated as norms to be used for standardization the data. The norms may be used to compare the motor ability of other population.
