Repetitions to failure versus not to failure during concurrent training in healthy elderly men: A randomized clinical trial.

Repetitions to failure versus not to failure during concurrent training in healthy elderly men: A randomized clinical trial. Exp Gerontol. 2018 Mar 22;: Authors: da Silva Neves LX, Teodoro JL, Menger E, Lopez P, Grazioli R, Farinha J, Moraes K, Bottaro M, Pinto RS, Izquierdo M, Cadore EL Abstract This randomized clinical trial compared the neuromuscular adaptations induced by concurrent training (CT) performed with repetitions to concentric failure and not to failure in elderly men. Fifty-two individuals (66.2 ± 5.2 years) completed the pre- and post-measurements and were divided into three groups: repetitions to failure (RFG, n = 17); repetitions not to failure (NFG, n = 20); and repetitions not to failure with total volume equalized to RFG (ENFG, n = 15). Participants were assessed in isometric knee extension peak torque (PTiso), maximal strength (1RM) in the leg press (LP) and knee extension (KE) exercises, quadriceps femoris muscle thickness (QF MT), specific tension, rate of torque development (RTD) at 50, 100 and 250 ms, countermovement jump (CMJ) and squat jump (SJ) performance, as well as maximal neuromuscular activity (EMGmax) of the vastus lateralis (VL) and rectus femoris (RF) muscles. CT was performed over 12 weeks, twice weekly. Along with each specific strength training program, each group also underwent an endurance training in the same session. After training, all groups improved similarly and s...
