What the study found
Caffeine improved jump height and power at some later measurements but did not improve the measured neuromuscular-fatigue outcomes or sprint performance.
Participants and protocol
Eleven male jumpers and sprinters completed eccentric-emphasis squat sessions and received caffeine or placebo during assessments one to three days later.
What this cannot establish
An improvement in a jump test does not show faster muscle repair or full recovery. The findings do not justify masking symptoms with caffeine or returning to hard training early.
