青年手球运动员在为期六个月协调训练项目期间的团体凝聚力与唾液催产素：一项前瞻性非随机对照干预研究

Background/Objectives: Whether coordination-based training can develop group cohesion in youth sport, and how cohesion relates to peripheral oxytocin, is unclear. We examined cohesion and salivary oxytocin during a six-month coordination- and cohesion-oriented program in junior handball players. Methods: Sixty-four male players (12–14 years) from four clubs joined a prospective, non-randomized, within-club controlled study (not prospectively registered). In each club, one pre-existing training slot (eight players) formed the experimental group (EG; n = 32) and the other the control group (CG;
