caffeine — increases countermovement jump height
LimitedEvidence strength: limited. Human evidence with several recorded weaknesses, or a design that tops out at limited.Findingreplicated ×4“Caffeine significantly increased CMJ jump height (+5.0%, ES = 0.82, p = 0.012), peak power (+2.5%, ES = 0.70, p = 0.027) and peak velocity (+1.8%, ES = 0.67, p = 0.033) during the concentric phase of the jump.”

caffeine — no detected effect on handgrip strength (hand dynamometer)
LimitedEvidence strength: limited. Human evidence with several recorded weaknesses, or a design that tops out at limited.FindingNull result“There were not differences between caffeine and placebo for handgrip force in either the dominant hand (48.22 ± 12.18 vs 48.38 ± 13.01 kg, ES = −0.06, p = 0.843) or the non-dominant hand (43.35 ± 11.35 vs 42.86 ± 12.25 kg, ES = 0.13, p = 0.642).”
