What the publication reports

Five players exceeded a smallest-worthwhile-change threshold for next-day sprint improvement after priming, but the between-condition differences were not statistically clear. Countermovement-jump performance did not improve at 24 hours.

Limits and interpretation

The very small sample and variable individual responses leave the average benefit uncertain. Within-condition changes do not establish superiority over control, and the study did not measure match performance or longer-term training adaptation.
