The Study
Unknown Title
This study looked at lots of experiments where soccer players did different kinds of training and measured how fast they ran or how high they jumped. Because the players were randomly assigned to groups, we can say that the training probably caused the improvements — not just that they happened together.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
Soccer players need to jump high, sprint fast, and run long — but you can't train for all of them at once without hurting your speed.

Key takeaways
Summary
Based on the study abstract and findings.
- 1These changes are meaningful: jumping higher and sprinting faster helps players win duels and break away, but too much endurance training can make you slower in short bursts — which is bad for soccer.
- 2Strength training makes you jump 2.5–2.8 cm higher and squat 31 kg more.
- 3Endurance training boosts oxygen use by 1.94 mL/kg/min.
- 4But if you train too much — over 300 MET-min/week — your jumps and sprints get worse.
- 5Sprinting and agility get worse the more you train.

In soccer players, endurance training produces a larger increase in maximal oxygen uptake than other types of training, with an average improvement of 1.94 mL/kg/min compared to regular training.
For soccer players, training between 297 and 352 MET-minutes per week produces the highest improvements in explosive power and maximal strength; training more than this reduces those gains.
Soccer players who do strength training show measurable increases in jump height and squat strength, and faster sprint times over 5, 10, and 30 meters, along with improved agility test performance compared to their baseline.
Soccer players who combine strength training and endurance training improve their explosive power, sprinting speed, and aerobic fitness more than those who do only one type of training.
