caffeine/Finding
One finding, on its own
A single claim from the graph, with the evidence strength computed from its study, the sentence it was drawn from, and the paper. This address does not change.
No detected effect on lower-body muscular strength (pooled composite)
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.FindingNull resultreplicated ×1“A subgroup analysis indicated that caffeine significantly improves upper (SMD = 0.21; 95% CI: 0.02, 0.39; p = 0.026; Fig. 3) but not lower body strength (SMD = 0.15; 95% CI: -0.05, 0.34; p = 0.147; Fig. 4).”

- meta-analysis
- Dose
- Acute pre-exercise ingestion (capsule, liquid or gel), mean 4.8 mg/kg, range 0.9-6 mg/kg, 45-60 min before testing
- Population
- Healthy adolescent and young-adult participants, trained and untrained, of both sexes; LOWER-BODY SUBGROUP of the pooled 1RM maximal-strength analysis, not the overall estimate. Constituent tests: back squat, leg press.
