“…This study is part of a large project, and data related to neuromuscular measures after 12 weeks of training (ie, maximum strength, torque development rate, maximal neuromuscular activity, and muscle thickness) have been published elsewhere . Data on functional capacity, muscle power output, blood pressure, lipid profile, and glucose after 12 weeks of training have also been published . In the present manuscript, we only included the comparisons between pre‐ to post‐20 weeks in order to focus in the long‐term adaptations.…”

“…Participants in the ENFG performed concurrent training with the ST workout performed at 50% of the possible RM in the target exercises, but with double the number of sets to be equal to the total ST volume as the RFG in these exercises. The strength and endurance training period from weeks 1 to 12 has been published previously . All the training sessions were carefully supervised by at least three experienced personal trainers.…”

“…In addition, Cadore et al have shown that CT using repetitions to failure and not to failure induced similar enhancements in sit‐to‐stand ability, muscle power output, VO 2peak , body composition, and serum HDL in older men. However, these studies verified adaptations following 12 weeks of training, while studies involving young populations investigated this issue across training periods ranging from 6 to 16 weeks . Thus, it remains unclear if the same findings (ie, similar adaptations to maximal and submaximal repetitions) would be observed over longer training interventions (ie, 20 weeks).…”

“…The magnitude of adaptations induced by CT fundamentally depends on the manipulation of acute training variables . Regarding strength training (ST), performing exercises leading to concentric failure (repetition maximum—RM) has received considerable attention from researchers; however, the additional benefits that this type of training can promote are still questionable, especially in the context of CT …”

“…Moreover, it seems that ST with maximal repetitions per set does not induce further muscle size gains in young subjects . Nevertheless, most of the above‐mentioned studies have investigated this issue in young adults, and to the best of the authors’ knowledge, only two studies have focused on the effects of ST using repetitions to failure or non‐failure in older men . Recently, Da Silva et al demonstrated that CT performed using repetitions not to failure (ie, submaximal repetitions) promoted similar gains in the maximal strength, muscle thickness, maximal neuromuscular activity, rate of torque development (RTD), and jumping performance in older men when compared to the repetitions to failure approach.…”

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.

Purpose There is a lack of information on the effects of power training (PT) as an alternative to traditional strength training (TST) during concurrent training (CT) in older individuals. This study aimed to verify the neuromuscular adaptations that occurred following 16-week interventions with two CT models in older men: high-intensity interval training (HIIT) combined with either TST or PT. Methods Thirty-five older men (65.8 ± 3.9 years) were randomly assigned into one of two training groups CTS: TST + HIIT (n = 18) or CTP: PT + HIIT (n = 17). CTS performed resistance training at intensities ranging from 65 to 80% of 1 RM at slow controlled speed, whereas CTP trained at intensities ranging from 40 to 60% of 1 RM at maximal intentional speed. Lower body one-repetition maximum (1 RM), isometric rate of force development (RFD), countermovement jump (CMJ) muscle power output, quadriceps femoris muscles thickness (QF MT), and peak oxygen uptake (VO 2peak ) were assessed before training and after 8 and 16 weeks of CT. Results Groups improved similarly in all primary outcomes (P < 0.05), with mean increases ranging: 1 RM (from 39.4 to 75.8%); RFD (from 9.9 to 64.8%); and CMJ muscle power (from 1.8 to 5.2%). Significant increases (P < 0.05) were observed in all secondary outcomes (QF MT, specific tension and VO 2peak ) with no differences between groups. Conclusion CT models were effective for improving maximal and explosive force (1 RM, RFD, and CMJ power), QF MT, and VO 2peak . Moreover, despite that using lower loading intensities, PT induced similar adaptations to those of TST.

The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living - experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent.
