“…Several recent studies conducted on strength-trained athletes have reported minor (2-5%; effect size, ES = 0.20-0.85) but significant muscle strength and/or power output enhancements not only against the one-repetition maximum (1RM) load but also at different submaximal loading intensities (% 1RM). These performance improvements were obtained, for instance, following different interventions such as short-term resistance training programmes (García-Pallarés, Sánchez-Medina, Carrasco, Díaz, & Izquierdo, 2009;Izquierdo-Gabarren et al, 2010), acute ingestion of ergogenic aids (Astorino, Martin, Schachtsiek, Wong, & Ng, 2011; or manipulation of time of day (i.e. circadian rhythm effect) (MoraRodríguez, García Pallarés, López-Samanes, Ortega, & Fernández-Elías, 2012;Pallarés, López-Samanes, et al, 2013).…”

This study analysed the effect of imposing a pause between the eccentric and concentric phases on the biological within-subject variation of velocity- and power-load isoinertial assessments. Seventeen resistance-trained athletes undertook a progressive loading test in the bench press (BP) and squat (SQ) exercises. Two trials at each load up to the one-repetition maximum (1RM) were performed using 2 techniques executed in random order: with (stop) and without (standard) a 2-s pause between the eccentric and concentric phases of each repetition. The stop technique resulted in a significantly lower coefficient of variation for the whole load-velocity relationship compared to the standard one, in both BP (2.9% vs. 4.1%; P = 0.02) and SQ (2.9% vs. 3.9%; P = 0.01). Test-retest intraclass correlation coefficients (ICCs) were r = 0.61-0.98 for the standard and r = 0.76-0.98 for the stop technique. Bland-Altman analysis showed that the error associated with the standard technique was 37.9% (BP) and 57.5% higher (SQ) than that associated with the stop technique. The biological within-subject variation is significantly reduced when a pause is imposed between the eccentric and concentric phases. Other relevant variables associated to the load-velocity and load-power relationships such as the contribution of the propulsive phase and the load that maximises power output remained basically unchanged.

“…Lack of attention to this issue is likely due to an assumption that RT should always be performed to muscular failure. However, increasing evidence seems to suggest that reaching repetition failure may not necessarily itnprove the magnitude of strength gains (10,14,20,21). Furthermore, in the case of not exercising to failure, the optimal number of repetitions to perfomi under different loading conditions to achieve certain training goals has not been established.…”

Velocity loss and metabolic stress clearly differs when manipulating the number of repetitions actually performed in each training set. The high correlations found between mechanical (velocity and countermovement jump height losses) and metabolic (lactate, ammonia) measures of fatigue support the validity of using velocity loss to objectively quantify neuromuscular fatigue during resistance training.

“…This phenomenon may occur due to the negative influence of endurance training performance on strength training-induced neuromuscular adaptations (Dolezal and Potteiger 1998;Kraemer et al 1995). Although several studies have focused on concurrent training in young populations García-Pallares and Izquierdo 2011;Izquierdo-Gabarren et al 2010;Cadore et al 2012c;Silva et al 2012), a limited number of studies have explored the effects of concurrent training on strength and endurance performance in older individuals (Izquierdo et al 2004;Cadore et al 2010Cadore et al , 2012aHolviala et al 2010;Sillampää et al 2008;Karavirta et al 2011). Certain studies have recently examined the influence of volume and intensity manipulation and the effects of the intra-session exercise sequence on concurrent training adaptations (Izquierdo et al 2004(Izquierdo et al , 2005Cadore et al 2010Cadore et al , 2011aCadore et al , 2012a.…”

The purpose of the present study was to review the scientific literature that investigated concurrent training adaptations in elderly populations, with the aim of identifying the optimal combination of both training program variables (i.e., strength and endurance) to avoid or minimize the interference effect in the elderly. Scielo, Science Citation Index, MEDLINE, Scopus, SPORTDiscus, and ScienceDirect databases were searched. Concurrent training is the most effective strategy by which to improve neuromuscular and cardiorespiratory functions as well as functional capacity in the elderly. The volume and frequency of training appears to play a critical role in concurrent training-induced adaptations in elderly subjects. Furthermore, new evidence indicates that the intra-session exercise order may influence the magnitude of physiological adaptations. Despite the interference effect on strength gains that is caused by concurrent training, this type of training is advantageous in that the combination of strength and endurance training produces both neuromuscular and cardiovascular adaptations in the elderly. The interference phenomenon may be observed in elderly subjects when a moderate weekly volume of concurrent training (i.e., three times per week) is performed. However, even with the occurrence of this phenomenon, the performance of three concurrent training sessions per week appears to optimize the strength gains in relative brief periods of training (12 weeks). Moreover, performing strength prior to endurance exercise may optimize both neuromuscular and cardiovascular gains.
