Exercise prescription to induce muscle strength and hypertrophy utilizes loads greater than 60% of an individual’s 1-repetition maximum (1RM). 1 Following knee injury or surgery, quadriceps weakness is a common impairment that limits physical performance and self-reported function. 2 – 4 One of

and high levels of power. 1 , 2 Furthermore, James et al 3 found that improvements in performance of high-velocity sporting actions are associated with preexisting strength levels. The 1-repetition maximum (1RM) is considered as the gold standard for assessing the maximal strength during dynamic

needed to maximize neuromuscular adaptations. 4 The most common method utilized to quantify resistance exercise intensity requires the determination of the 1-repetition maximum (1RM). 5 Once the 1RM is known, the loads can be applied relative to the 1RM value (%1RM). As the direct determination of the

The 1-repetition maximum (1RM) is defined as the maximum load that can be lifted just once in a given exercise. 1 The 1RM is one of the variables most commonly reported to assess the efficacy of various training and rehabilitation interventions as it is considered a valid indicator of maximal

The absolute differences between the actual and predicted 1RM revealed a significant main effect for device ( F 2.2,21.9  = 15.3, P  < .001), but not

Traditional percentage-based resistance training (PBT) involves prescribing submaximal loads calculated from a 1-repetition-maximum (1RM) assessment. Strength and conditioning coaches can utilize PBT methods to periodize training load and volume to accommodate for recovery and improve sports

aim of the present study was to compare the effects of 2 upper-body strength training programs differing only in the set configuration (TR and RR) on the BP 1-repetition maximum (BP1RM), BP throw peak velocity against 30 kg (BPT30), and handball throwing velocity (HTV). As a secondary aim, we explored

For example, Lockie et al 18 observed greater peak power and velocity for the BP 1-repetition maximum (1RM) load using a close
