Abstract Background Even from a young age, modern soccer requires high levels of physical fitness development, particularly jumping and sprinting. Plyometric jump training (PJT), combined with young athletes’ regular soccer sessions, has the potential to improve jumping and sprinting. However, studies exploring the effects of PJT are generally limited by small sample sizes. This problem of underpowered studies may, thus, be resolved by pooling study results in a meta-analysis. Objective The objective of this systematic review with meta-analysis (SRMA) was to assess the effects of plyometric jump training (PJT) on jumping and sprinting among young male soccer players. Methods The SRMA included peer-reviewed articles that incorporated PJT in healthy players (i.e., 7-week duration and > 14 sessions, suggesting a greater return from exposure to longer PJT interventions, partially in support for the adoption of a long-term approach to athletic development in young athletes. However, with reference to the findings of the meta-regression, and those from the remaining subgroup and single factors analysis, a robust confirmation regarding the moderator role of participant’s age or PJT configuration effects on young soccer player’s fitness qualities needed.
Key Points Jumping and sprinting are key physical fitness proxies of soccer performance for young players. Plyometric jump training may improve both jumping and sprinting performance.

Plyometric jump training may be particularly effective after interventions > 7 weeks.

1 Introduction Even from a young age, modern soccer requires high levels of physical fitness development [1–3]. Although aerobic physical fitness is important during a soccer game [2], maximal- or near-maximal-intensity single-bout efforts are key factors for optimal physical performance [1, 4, 5]. Therefore, aside from endurance activity, soccer players must also perform numerous explosive actions [6], including jumping, kicking, accelerating, decelerating and changing of movement direction, with most of these preceding goal-scoring opportunities in competitive leagues [4, 7]. Specifically, the straight sprint (45%) and the vertical jump (16%) have been shown to be the two most frequent actions preceding goal situations in soccer [4]. Moreover, a significant relationship between team average for vertical jump height and the final league standi
