What the publication reports
Forty athletes were randomised across three sprint groups and an active control. Three-second bouts produced larger gains in jumping, sprinting, reactive strength and peak power than nine-second bouts, while nine-second bouts favoured change of direction and mean power.
Limits and interpretation
Each group contained only ten male athletes, the intervention lasted six weeks and no independent replication was reported. Results may not generalise to girls, adults or other sports.
