The Dose-Response Relationship Between Training Load and Aerobic Fitness in Academy Rugby Union Players.

abstract：PURPOSE:To determine if the mathematical model used to derive critical power could be used to identify the critical resistance (CR) for the deadlift; compare predicted and actual repetitions to failure at 50%, 60%, 70%, and 80% 1-repetition maximum (1RM); and compare the CR with the estimated sustainable resistance for...
