Compare Countermovement Squat Jump performance and body composition between forward and back rugby players

<p dir="ltr">Dataset for research: <b>Evaluating countermovement squat jumps as a performance marker between different rugby positions</b></p><p dir="ltr">This study compared Countermovement Squat Jump (CMJ) performance and body composition between forward and back rugby players during pre- and in-season phases and examined position-specific relationships between these variables. Sixty male rugby players were analysed (backs: n = 22; forwards: n = 38).

CMJ performance metrics, including force, power, velocity, acceleration, total work, volume load per superset, and repetition duration, were recorded using a wearable accelerometer. Body composition variables (weight, height, body mass index (BMI), fat percentage, extracellular water ratio (ECW), skeletal muscle mass (SMM), and fat-free mass (FFM)) were assessed via bioelectrical impedance analysis in a subset of players (n = 37).
