“…Thus, the training load has been determined from the relative load (% of the maximum load of one repetition, 1RM), being the main factor of control and determination of the intensity and fatigue relative to the strength training [4,5]. Although these variables are used to control training, their use can induce excess fatigue and mechanical and metabolic tension [6][7][8][9][10].…”

Background: Paralympic powerlifting (PP) presents adaptations that the training tends to provide, mainly concerning the mechanical variables. Objective: Our aim was to analyze mechanical, dynamic and static indicators, at different intensities, on the performance of paralympic powerlifting athletes. Methods: 23 athletes of PP, 11 national level (NL) and 12 regional level (RL) performed dynamic and static tests over a comprehensive range of loads. The study evaluated regional and national level athletes and the influence on the training level on the performance of strength. The study was carried out in four weeks, with the first week to familiarize with the one repetition maximum (1RM), day 1, and there was a 72-h rest and familiarization with dynamic and static tests carried out day 2. In week 2, the 1RM tests were performed (day 1 and 72 h later), and the static tests were performed with a distance of 15 cm from the bar to the chest, with the tests of maximum isometric strength, time to maximum isometric strength, rate of force development (RFD), impulse, variability and fatigue index (IF) taking place on day 2. In weeks three and four dynamic tests were performed, including means propulsive velocity, maximum velocity, power and prediction of one maximum repeat. Results: Differences were found, with better results than for RL in relation to NL in MVP (45%, 55%, and 75% 1RM), in VMax (50%, 55%, 75% and 95% 1RM). In power, the NL had better results (40%, 45%, 50%, 60% and 95% 1RM). Conclusion: RL athletes tend to present better results with regard to velocity, however in power, NL athletes tend to present better performances.

“…It is speculated that there might be an optimal level of induced neuromuscular fatigue after each RT session to maximize adaptation. Although some studies [1,8] suggest that muscle failure may be needed to maximize muscle mass and strength, increasing evidence seems to indicate that reaching repetition failure during an exercise set may not necessarily improve the magnitude of strength gains [9,10], especially when training is not solely aimed at muscle hypertrophy but, rather, it must serve to develop specific neuromuscular adaptations to improve athletic performance. It has been shown that performing repetitions to failure causes a marked disruption of cellular homeostasis, as reflected by a nearcomplete depletion of phosphocreatine stores, a significant reduction of adenosine triphosphate and muscle total adenine nucleotide pool, as well…”

Short-term Recovery Following Resistance Exercise Leading or not to Failure

et al. 2015

This study analyzed the time course of recovery following 2 resistance exercise protocols differing in level of effort: maximum (to failure) vs. half-maximum number of repetitions per set. 9 males performed 3 sets of 4 vs. 8 repetitions with their 80% 1RM load, 3?4(8) vs. 3?8(8), in the bench press and squat. Several time-points from 24?h pre- to 48?h post-exercise were established to assess the mechanical (countermovement jump height, CMJ; velocity against the 1?m?s?1 load, V1-load), biochemical (testosterone, cortisol, GH, prolactin, IGF-1, CK) and heart rate variability (HRV) and complexity (HRC) response to exercise. 3?8(8) resulted in greater neuromuscular fatigue (higher reductions in repetition velocity and velocity against V1-load) than 3?4(8). CMJ remained reduced up to 48?h post-exercise following 3?8(8), whereas it was recovered after 6?h for 3?4(8). Significantly greater prolactin and IGF-1 levels were found for 3?8(8) vs. 3?4(8). Significant reductions in HRV and HRC were observed for 3?8(8) vs. 3?4(8) in the immediate recovery. Performing a half-maximum number of repetitions per set resulted in: 1) a stimulus of faster mean repetition velocities; 2) lower impairment of neuromuscular performance and faster recovery; 3) reduced hormonal response and muscle damage; and 4) lower reduction in HRV and HRC following exercise.

“…Thus, there remains a dearth of literature considering the acute fatigue response and practical implications of exercising to momentary failure considering heavier and lighter load resistance training strategies. Further, because advanced training methods, such as forced repetition and breakdown set training, are commonly used and intended to increase fatigue from resistance training, these should also be investigated.…”
