What the publication reports
Pooled effects favoured complex training for countermovement jumps, squat jumps, agility and sprint performance. The countermovement-jump effect size was 0.58; the authors rated overall certainty moderate. Responses varied with athlete characteristics and programme parameters.
Limits and interpretation
Heterogeneity was substantial for several outcomes. Dose-response analyses compare different studies and should not be treated as randomized proof of an optimal number of sets or repetitions. Performance-test improvements do not automatically translate into better match outcomes or reduced injury risk.
