This study aimed to determine the relationship between lower-limb explosive strength and selected morphological characteristics in soccer players aged 13, 14, and 15 years, as well as to identify differences between the age groups. The sample consisted of 45 youth soccer players (n = 45), with 15 participants in each age category, recruited from a local soccer club.
The morphological characteristics assessed included body height, body mass, leg length, body fat percentage, and muscle mass. Lower-limb explosive strength was evaluated using the following tests: squat jump, countermovement jump, drop jump, stiffness test, and standing long jump.
The results demonstrated that muscle mass and leg length positively correlated with explosive performance, whereas body fat percentage showed a negative correlation. Statistically significant differences were also found between the age groups for most variables, with the oldest players (15 years) achieving superior performance across all explosive strength tests.
