The Claim
Caffeine ingestion is associated with improved vertical jumping performance across doses of ≤3 mg/kg and >3 mg/kg, with no significant difference in effect size between low and high doses (g = 0.21 vs. g = 0.37) in females.
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.
In females, consuming caffeine improves vertical jump performance at both low doses (≤3 mg/kg) and high doses (>3 mg/kg), and the improvement is similar regardless of dose.
See the scientific wording
Caffeine ingestion is associated with improved vertical jumping performance across a range of doses (≤3 mg/kg and >3 mg/kg), with no significant difference in effect size between low and high doses (g = 0.21 vs. g = 0.37), suggesting dose-response may not be linear in females.
Caffeine blocks signals that slow down brain activity, making the brain send stronger and faster signals to the muscles, which makes the legs push harder and higher during a jump.
What the research says
1 studyThis study found that women who took caffeine—whether a small or large amount—jumped higher than when they didn’t take it, and the bigger dose didn’t help much more than the smaller one. So, caffeine helps jumping, but more isn’t necessarily better.
