Main findings of the physical fitness outcomes.
| Study | Physical Fitness—Evidence of the Main Findings (Differences or Not after Training Programs in Terms of the Main Physical Fitness Outcomes) | General Effects of Soccer Training |
|---|---|---|
| [39] | 6-month soccer training improved maximal power output, balance, flexibility, jump ability, agility, and cardiorespiratory fitness in overweight children. | Favorable |
| [40] | 11-week soccer training improved the ability of a 20-m sprint and cardiorespiratory fitness performance in children. | Favorable |
| [41] | 12-week soccer training increased the VO2peak in obese adolescents. | Favorable |
| [42] | 8-week soccer training increased cardiorespiratory fitness and 20-m sprint performance in untrained adolescents. | Favorable |
| [35] | 12-week soccer training increased explosive power and flexibility of lower extremities in overweight children. | Favorable |
| [36] | 12-week soccer training increased agility and cardiorespiratory fitness in overweight and obese children. | Favorable |
| [43] | 8-week soccer training decreased time in sprint performance (10 and 20 m), and increased jump ability, balance, and cardiorespiratory fitness in adolescents. | Favorable |
| [38] | 10-month soccer training improved cardiorespiratory fitness, although without significant differences in children. | Favorable |
| [45] | 11 weeks of “FIFA 11 for Health” improved balance and cardiorespiratory fitness in both genders. Specifically, when only girls were analyzed, cardiorespiratory fitness and jump ability were improved, while boys only improved cardiorespiratory fitness in children. | Favorable |
| [37] | 10-week soccer training improved cardiorespiratory fitness, VO2peak, 50-m sprinting ability, jump ability, core muscle strength, and balance in children. | Favorable |
| [46] | 8-month soccer training improved resistance in the upper body and cardiorespiratory fitness in adolescents. | Favorable |
| [49] | 8-week soccer training improved abdominal strength and cardiorespiratory fitness in adolescents. | Favorable |
| [50] | An 11-week study of “11 for Health in Denmark” showed positive cardiorespiratory fitness and VO2max levels in children. | Favorable |
Abbreviations:VO2max: maximal oxygen uptake; VO2peak: the peak of oxygen uptake.
