“…The diversity of systematic reviews in recreational soccer is clear from the extant literature [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. As can be seen from the available systematic reviews, some have focused on specific outcomes, such as bone health [ 26 , 27 ], fat mass [ 22 ], or maximal oxygen uptake [ 20 ], while others summarized the effects on different outcomes [ 21 , 23 , 24 , 25 ]. Additionally, half of these systematic reviews were exclusively dedicated to adult populations [ 21 , 22 , 26 , 27 ], while the remaining reviews focused on mixed populations, such as children, adolescents, adults, and older individuals (both healthy and unhealthy), thus making it difficult to determine a clear overview of the effects on children and youths [ 20 , 23 , 24 , 25 ].…”
