The Claim
In male academy soccer players, one weekly session of resistance training, regardless of whether it is high-intensity low-volume or moderate-intensity high-volume, significantly improves lower-body strength and power compared to soccer training alone, but does not affect 10-meter, 20-meter, or 30-meter sprint performance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Male academy soccer players who add one weekly resistance training session to their regular soccer training become stronger and more powerful in their legs, but their sprint times over 10, 20, and 30 meters do not change.
See the scientific wording
In male academy soccer players, one weekly session of resistance training—whether high-intensity low-volume or moderate-intensity high-volume—significantly improves lower-body strength and power compared to soccer training alone, but has no effect on 10-, 20-, or 30-meter sprint performance.
Lifting heavy weights trains the nervous system to activate more muscle fibers faster, making the legs stronger and more powerful for jumping and squatting, but does not change how fast the legs can move during short sprints because sprint speed depends on different muscle timing and coordination patterns.
What the research says
1 studyAdding one weekly weight-training session made these young soccer players stronger and better at jumping, but didn’t make them run any faster over short distances. The study proves this exactly as the claim says.
