This report aims to generate an evidence-based debate of the Critical Power (CP), or its analogous Critical Speed (CS), concept. Race times of top Spanish runners were utilized to calculate CS based on three (1500-m to 5000-m; CS1.5-5km ) and four (1500-m to 10000-m; CS1.5-10km ) distance performances. Male running world records from 1000 to 5000-m...

... In light of the ongoing debate about how to best characterize the highest PO at which whole-body physiologic variables stabilize, i.e. the H/VH border e.g. [26,27], it is worth noting that the H/VH borders determined on the basis of CP, maximal lactate steady-state (MLSS) or respiratory compensation point (RCP) do not have to overlap. The reason is that CP is a property of, and generated within, active muscles (see [14] for discussion), while MLSS and RCP are systemic events not only related to the muscle-generated CP but also influenced by other factors (the balance of lactate appearance and clearance, the senstitvity of the carotid body to an acidosis, or the absence of mechanical constraints limiting ventilation; [21,28,29]). ...
... In addition to their usual running training, we referred participants to follow the advice given by Stryd for an accurate CP: threshold itself. It has also been suggested that CP is simply a mathematical artefact [17]. ...
... Lower intra-set neuromuscular fatigue (i.e., lower velocity loss thresholds) may be superior for optimizing neuromuscular adaptations such as power output and shifts towards velocity-oriented force-velocity profiles; whereas higher intra-set neuromuscular fatigue (i.e., higher velocity loss thresholds) may be superior for optimizing muscular endurance [26]. The available evidence remains unclear which velocity loss thresholds optimize chronic strength and hypertrophy adaptations [27][28][29][30][31][32][33][34][35][36]. ...
... At the beginning, at the exercises (e.g., percentage of the 1 repetition maximum) (González-Badillo & Sánchez-Medina, 2010). Therefore, velocity-and power-load relationship in half squat has been studied, including the optimal load for reaching maximal power (Martínez-Cava et al., 2019). Further, vertical jumps as countermovement jump (CMJ) require brief contraction times and high RFD (Lago-Rodríguez et al., 2021), and are associated with sprint performance (Stanton, Wintour & Kean, 2017), and success in other sport modalities. ...
... Alternatively, when sets and percentage of 1RM are matched, autoregulating intra-set volume with velocity loss thresholds (i.e., reducing neuromuscular fatigue) also results in significantly greater 1RM strength adaptations [28]. When equated for intra-set fatigue, the time course of recovery is similar regardless of the proximity to failure and relative intensity; however, when proximity to failure is equated, training with greater intra-set fatigue results in greater elevations in indirect measures of muscle damage compared to lower intra-set fatigue [44]. Crucially, excessive acute muscle damage attenuates high-threshold motor unit recruitment and motor skill learning; thus, impairing overall performance, training quality, and skill practice [45]. ...
... Proximity to failure and neuromuscular fatigue is of paramount importance when considering the design of RT programs [37]. Although training to failure has traditionally been promoted for overload [38,39], this practice elevates muscle damage and elongates recovery time considerably compared to not training to failure [40]. Importantly, two recent systematic reviews and metaanalyses demonstrated no difference in hypertrophy between training to failure compared to not training to failure when volume was equalized [41,42]. ...
... Specifically, subjective load autoregulation involves implementing the repetitions in reserve-based rating of perceived exertion scale (RIR-based RPE scale) in an attempt to quantify proximity to failure, which is commonly referred to as RPE-based training [10]. However, due to the inaccuracy in intra-set RPE predictions [11], objective velocity-based training (VBT) [12] has emerged as a novel load autoregulatory strategy to rectify the limitations of subjective RPE-based training [13] and standardized PBT [14]. VBT load autoregulation involves either prescribing an average concentric velocity (ACV) zone corresponding to the force-velocity continuum [15,16] or an individualized first repetition average concentric velocity (FRV) corresponding to a specific percentage of 1RM via an individualized load-velocity profile [17][18][19]. ...
... The total rest period (15 minutes for each exercise) was the same for both groups. The load (75% 1RM) was prescribed to match an initial MV of 0.70 m·s 21 in the SQ and 0.61 m·s 21 in the BP (11,27,33). Of note is that subjects in the TRG approximately performed half of the maximum number of repetitions in each set that could be completed before reaching muscular failure. ...

The available evidence remains unclear which velocity loss thresholds optimize chronic strength and hypertrophy adaptations [27][28][29][30][31][32][33][34][35][36]. ...
