Using 30-s Prone Back Extension Repetition Maximum Test to Predict Concentric and Eccentric 1 Repetition Maximum Squat Strength in Young and Older Adults

Discussion: Novel data from our study show that 30-s prone back extension repetition ivoryjinelle.com maximum can predict 1RM of concentric and eccentric squat strength in young and older adults, respectively.Thus, clinicians and rehabilitation read more professionals can use our novel equations to design concentric- and eccentric-biased resistive training programs in young and older adults, respectively, without testing for 1RM.
