BACKGROUND: This study aims to explore the effects of plyometric training (PT) and strength training (ST) on the physical attributes of male adolescent team sports athletes, and further analyze the moderating variables that may have a potential impact on training effectiveness. METHODS: This study searched PubMed, Web of Science, Cochrane, Embase, and SPORTDiscus databases from the establishment of the databases to August 28, 2024. To determine a randomized controlled trial evaluating the impact of ST and PT on the physical fitness attributes (0-10 m accelerate speed, linear sprint speed, change-of-direction speed, vertical jump, horizontal jump and muscle strength) of male adolescent team sports athletes. The risk of bias was evaluated using the latest version of the Cochrane risk-of-bias tool for randomized trials. Meta-analysis used the random effects model in Stata 15.0. Subgroup analyses were conducted based on the characteristics of the participants (age, height and weight) and the variables of the training program (training duration, training frequency, number of sets, total sessions, repetitions, rest between sets, mean session duration). RESULTS: A total of 69 studies were included, involving 2051 male adolescent team sports athletes. Meta-analysis indicates that both PT and ST have significant but varying effects on male adolescent team sports athletes. Specifically, they showed small to moderate improvements in 0-10 m acceleration (PT, ES: -0.60, moderate; ST, ES: -0.71, moderate), linear sprint speed (PT, ES: -0.56, small; ST, ES: -0.41, small), change-of-direction speed (PT, ES: -0.79, moderate; ST, ES: -0.92, moderate), vertical jump (PT, ES: 0.86, moderate; ST, ES: 0.58, small), and horizontal jump (PT, ES: 0.68, moderate; ST, ES: 0.61, moderate). ST notably impacts (ES: 1.49, large) muscle strength, whereas PT does not have a significant effect. Subgroup analysis of PT shows that the training program with sets (>/= 6 sets, for 0-10 m accelerate speed; >/= 4 sets, for vertical jump), total sessions (>/= 16 sessions, for 0-10 m accelerate speed and for change-of-direction speed; >/= 13sessions, for horizontal jump), frequency (> 2 sessions per week, for linear sprint speed), rest between sets (< 90 s, for linear sprint speed), or repetitions (>/= 9 repetitions, for horizontal jump) were more effective; The effect was better for those who are older (16-18 years) (for 0-10 m acceleration, and change-of-direction) and taller (>/= 171 cm) (for 0-10 m acceleration). Subgroup analysis of ST indicated that the training duration was shorter ( 6 repetitions, for 0-10 m accelerate speed), shorter rest between sets (/= 120 s, for change-of-direction speed), the mean session duration was relatively short ( 8 weeks, for horizontal jump), or have shorter total sessions (
