Abstract
Background and Aim: This study examined the effects of a body‑weight post‑activation performance enhancement (PAPE)‑based warm‑up on knee kinematics during single‑leg landing in male basketball players.
Methods: Twenty semi‑professional male basketball players (Kerman, Iran) participated in this quasi‑experimental, within‑subject crossover study. Each participant completed a general warm‑up and a body‑weight PAPE warm‑up (general warm‑up plus 3 × 10 body‑weight squats, 30‑s rest, followed by 2‑min rest). Participants then performed three single‑leg landings from a 30‑cm height with the dominant leg. Kinematic data were captured using a six‑camera motion analysis system (Motion Analysis Raptor‑H) with Cortex 5.2 software and processed in MATLAB. Outcome measures were maximal knee flexion, eccentric knee angular velocity, and knee valgus angle. Data were analysed using Shapiro–Wilk and paired t‑tests (α = 0.05).
Results: No significant difference was observed in maximal knee flexion between conditions (d = 0.02, p = 0.96). However, PAPE significantly reduced eccentric knee angular velocity (d = 0.52, p = 0.03) and knee valgus angle (d = 0.94, p < 0.001) during landing.
Conclusion: A body‑weight PAPE‑based warm‑up effectively lowered eccentric knee angular velocity and knee valgus without significantly altering maximal knee flexion. This simple, equipment‑free strategy may serve as a practical approach to improve knee motor control during single‑leg landing in male basketball players.
