Surface: type of surface on which training intervention were performed; dose: studies that reported total dose used in their training intervention (could be reported as foot contacts per leg, number of jumps, time, velocity, strength, etc.); habitual training: studies that reported if intervention period was added or replaced by their usual training; combined?: studies in which PJT was combined with another type of training; duration: intervention duration; frequency: total number of training used per week during training interventions; intensity: PJT training intensity reported; progressive overload: overload followed during PJT intervention period; tapering: reduction of any training variables previous post-tests; rest/sets: rest between sets during PJT exercises; rest/sessions: rest between PJT training sessions; NCR: not clearly reported among eligible articles.
