The Claim

Strength training significantly improves counter movement jump height by 2.55 cm (95% CI: 1.17–3.92), squat jump height by 2.81 cm (95% CI: 1.29–4.32), 1-repetition maximum squat strength by 31.23 kg (95% CI: 24.17–38.30), reduces 5-meter sprint time by 0.09 seconds (95% CI: 0.06–0.12), 10-meter sprint time by 0.09 seconds (95% CI: 0.05–0.13), 30-meter sprint time by 0.18 seconds (95% CI: 0.09–0.27), and improves T-test agility time in soccer players, with the highest probability of being the most effective intervention across all measured physical outcomes.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative
1 study reviewed
In plain English

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.

See the scientific wording

Strength training significantly improves explosive power, sprint performance, and agility in soccer players, increasing counter movement jump height by 2.55 cm (95% CI: 1.17–3.92), squat jump height by 2.81 cm (95% CI: 1.29–4.32), 1-repetition maximum squat strength by 31.23 kg (95% CI: 24.17–38.30), reducing 5-meter sprint time by 0.09 seconds (95% CI: 0.06–0.12), 10-meter sprint time by 0.09 seconds (95% CI: 0.05–0.13), 30-meter sprint time by 0.18 seconds (95% CI: 0.09–0.27), and improving T-test agility time, with the highest probability of being the most effective intervention across all measured physical outcomes.

Why this might work

Lifting heavy weights makes muscle fibers thicker and trains the nervous system to activate more muscle fibers at once, which lets the body push harder and move faster during jumps and sprints.

    This study found that when soccer players do strength training, they jump higher, run faster over short distances, and change direction better than when they do other kinds of exercise. It’s the best workout for these skills.
