Concurrent training performed with and without repetitions to failure in older men: A randomized clinical trial

Abstract

This study compared the effects of 20 weeks of concurrent training with and without repetitions to failure on neuromuscular and functional adaptations in older men. Methods Thirty‐six older men (67.1 ± 5.1 years) were randomized into three groups: one performing repetitions to failure (RFG, n = 13), another performing repetitions not to failure and 50% of the repetitions of the RFG (NFG, n = 12), and a third performing repetitions not to failure with equal training volume of the RFG (ENFG, n = 11). Training was performed twice a week for 20 weeks at intensities ranging from 65% to 80% of maximal strength. In each session, the individuals started with strengthening exercises and then performed aerobic exercise on a treadmill. Before and after the intervention, individuals were assessed for their one repetition maximum (1RM) for leg press (LP) and knee extension (KE) exercises, knee extensors’ isometric peak torque (PTiso), and rate of torque development (RTD) at 50 ms, 100 ms, and 250 ms, muscle thickness of the quadriceps, as well as functional performance on sit‐to‐stand, and timed up and go tests. Results After training, there were significant (P < 0.001) increases in the LP and KE 1RM, PTiso, and RTD outcomes in all groups. Also, there were significant increases in muscle thickness of the quadriceps and in the sit‐to‐stand test (P < 0.05) in all groups. No significant differences were observed between groups in any outcome. Conclusion Concurrent training using repetitions to concentric failure did not promote additional benefits for neuromuscular function, muscle thickness, or functional capacity of older individuals.

Effects of high-intensity interval training combined with traditional strength or power training on functionality and physical fitness in healthy older men: A randomized controlled trial

“…Likewise, marked gains in TUG and stair-climbing performance were observed after 16 weeks of concurrent training (i.e., approximately +7% and +11%, respectively). These findings are in agreement with previous study reports investigating the translational benefits of strength training (Sayers et al, 2007;Bottaro et al, 2007;Bean et al, 2002;Ramirez-Campillo et al, 2014;BeltranValls et al, 2014) or concurrent training (Wood et al, 2001;Wilhelm et al, 2014;Cadore et al, 2018;Teodoro et al, 2019) on functional capacity in older populations, showing similar magnitudes of improvements produced by the two exercise paradigms.…”

Efectos de un programa de Aprendizaje-Servicio sobre Ejercicio Físico concurrente con personas adultas-mayores: Pilates y juegos de socialización (Effects of a Concurrent Physical Activity Service-Learning program with older adults: Pilates and socializa

“…Actualmente, múltiples estudios recientes (Barajas-Galindo, González, Vicente, Ballesteros-Pomara, , 2021; Fougner et al, 2018;Giovanni et al, 2022;León-Olivares, Capella-Peris, Chiva-Bartoll, & Ruiz-Montero, 2019;Müller et al, 2021;Pothier et al, 2021), en la línea de la presente investigación, tratan de averiguar los posibles beneficios que el ejercicio físico puede proporcionar a los adultos-mayores. Específicamente, los programas de entrenamiento concurrente, que, como nos explica Teodoro et al (2019), son programas donde la combinación de fuerza y resistencia aeróbica simultáneamente, son un instrumento ideal para la mejora de la salud mental y física en personas adultas-mayores.…”

“…Un programa de entrenamiento concurrente consiste en combinar el trabajo de dos capacidades físicas: fuerza y resistencia. Se ha evidenciado que el entrenamiento concurrente es una estrategia ideal para minimizar las deficiencias neuromusculares y cardiovasculares que aparecen con el envejecimiento (Teodoro et al, 2019), ya que se trata de un modelo de entrenamiento ideal para el mantenimiento de la capacidad funcional a medida que envejecemos, además de mejorar la función neuromuscular, la capacidad cardiorrespiratoria e índices de composición corporal en adultos-mayores (Müller et al, 2021). Dicho estudio realizó un programa de entrenamiento con personas mayores combinando entrenamiento de fuerza junto con entrenamiento interválico de alta intensidad (siglas en inglés, HIIT) y concluyó que las mejoras fueron similares entre los adultos sanos y los adultos que tenían adaptaciones psicológicas y/o funcionales, por lo que, si un adulto mayor (como es el caso en este estudio) tiene dificultades para realizar algunos ejercicios es esencial adaptar las sesiones a sus capacidades, ya que puede mejorar tanto como un adulto que no necesite adaptaciones.…”

Strength Training Volume to Increase Muscle Mass Responsiveness in Older Individuals: Weekly Sets Based Approach

“…Third, dose–response should be investigated through within-subject experimental protocols and long-term interventions. On the latter, if, on the one hand, the duration of the intervention has been considered one of the most relevant ST variables for elderly individuals (Nicola and Catherine, 2011 ; Radaelli et al, 2014b ), on the other hand, prolonged interventions could minimize the influence of the training volume on the hypertrophic response (Da Silva et al, 2018 ; Teodoro et al, 2019 ). In future investigations, it is imperative to separate the true interindividual response variance from other sources of variance, since the individual observed changes are the sum of the change caused by the training program, plus the change that would have occurred in the absence of intervention (in the control group), plus measurement error and day-to-day biological variability (Ross et al, 2019 ).…”
