The purpose of this study was to determine the relationships between lower and upper extremity muscle strength and endurance, speed, and repeated sprint ability (RSA) in young soccer players. Twenty-two young soccer players (age: 16.20±.77 years) participated in the study. The player’s strength, endurance, speed, and RSA were measured. Correlations between variables were performed with Pearson product-moment correlation analysis. A significant moderate negative correlation (MNC) was found between right leg extension strength (LES) and 10m and 30m sprint performances (SP). A moderate MNC was determined between left LES and 30m SP. A moderate MNC was determined between shoulder press strength and 10m, and 30m sprint, and the best result of repeated SP. A significant MNC was determined between squat strength and 30m SP. The MNC between muscle strength and SP showed that any increase in quadriceps and hamstring muscle strength in young soccer players would positively affect SP.

Keywords: Young soccer, motor performance, strength, endurance, sprint, and repeated ability.
