“…Although the aforementioned studies implemented increases in training volume mainly by manipulating the number of weekly sets/muscle group, the relevance of volume progression was also confirmed by other investigations that achieved VL increases by keeping the same number of sets and repetition range but by regulating only the load lifted in each exercise throughout the intervention period [4,25]. Damas et al [4], for example, noted similar increases on muscle cross-sectional area of the vastus lateralis of resistance-trained men submitted to training protocols (8 weeks) differing for total VL but with an equal VL progression.…”

“…Damas et al [4], for example, noted similar increases on muscle cross-sectional area of the vastus lateralis of resistance-trained men submitted to training protocols (8 weeks) differing for total VL but with an equal VL progression. Additionally, a recent study also reported that, despite the larger VL accumulated over the training period, no significant differences for the increases in muscle thickness of both lower and upper limbs muscles emerged between experimental groups that presented similar VL progression over the weeks [25]. Therefore, based on these findings, it can be suggested that VL progression, rather than accumu-lated VL, might be a more suitable variable to be controlled by programs that aim to potentiate muscle hypertrophy outcomes.…”

Muscle Hypertrophy Responses to Changes in Training Volume: A Retrospective Analysis

This study assessed associations between changes in the weekly number of sets performed and the percentage change in muscle thickness of the biceps (MTBB) and triceps (MTTB) brachii muscles. Through a retrospective analysis, sixty-eight resistance-trained subjects that participated in previous studies had their previous training volumes analyzed and compared to the volume imposed during each individual study. The relationship between variables was determined through Spearman correlation and a k-cluster analysis was performed to subdivide the participants into three groups and classified as:<0%; 0–50%, and >50% increase in the number of sets for both muscle groups. Moderate and weak correlations were observed between the alterations in training volume and changes in MTBB (rs=0.44, p=0.001) and MTTB (rs=0.35, p=0.002), respectively. A significant difference was noted between<0% to >50% for MTBB and MTTB (p=0.017; p=0.042, respectively), while no significant difference was observed between<0% to 0–50% and 0–50% to >50% (both p >0.05) for both muscle groups. In conclusion, muscle hypertrophy of the upper limbs is only weakly to moderately associated with changes in training volume of trained subjects.

“…A recent investigation (7) into training frequency (i.e., number of sessions per muscle group per week) and muscle hypertrophy in resistance-trained individuals found that 8 and 4 training sessions per week (4 and 8 sets/session, respectively i.e., 32 total sets/wk) resulted in similar increases in muscle size. These findings are consistent with the meta-analysis of Schoenfeld et al (29), which concluded no additive effect of increased training frequency on muscle hypertrophy, provided that the higher- and lower-frequency training programs were volume matched throughout the week.…”

Resistance training volume has been suggested to be one of the most effective variables for developing muscular hypertrophy. Meta-analyses have concluded that there exists a dose-response relationship between weekly resistance training volume (i.e., the number of sets performed over the training week) and muscle mass accrual in nonresistance-trained individuals; however, experimental data in resistance-trained individuals have shown conflicting results. Current literature suggests that the performance of additional sets of resistance exercise within a single training session and training week does not inherently result in greater increases in muscle size compared with groups or conditions that perform lower volumes of resistance training. Notwithstanding these results, it has been suggested that controlling for each individual's previous training volume could improve the precision of the muscle hypertrophic response to resistance training and that failing to do so would disregard the principle of progressive overload. Herein, we explore the evidence for the suggestion that a higher-volume approach to training, in comparison to what an individual has been accustomed to, would improve the precision of the muscle growth response to resistance training and the physiological rationale that may (or may not) underpin this phenomenon.

Background Climbing is an intricate sport composed of various disciplines, holds, styles, distances between holds, and levels of difficulty. In highly skilled climbers the potential for further strength-specific adaptations to increase performance may be marginal in elite climbers. With an eye on the upcoming 2024 Paris Olympics, more climbers are trying to maximize performance and improve training strategies. The relationships between muscular strength and climbing performance, as well as the role of strength in injury prevention, remain to be fully elucidated. This narrative review seeks to discuss the current literature regarding the effect of resistance training in improving maximal strength, muscle hypertrophy, muscular power, and local muscular endurance on climbing performance, and as a strategy to prevent injuries. Main Body Since sport climbing requires exerting forces against gravity to maintain grip and move the body along the route, it is generally accepted that a climber`s absolute and relative muscular strength are important for climbing performance. Performance characteristics of forearm flexor muscles (hang-time on ledge, force output, rate of force development, and oxidative capacity) discriminate between climbing performance level, climbing styles, and between climbers and non-climbers. Strength of the hand and wrist flexors, shoulders and upper limbs has gained much attention in the scientific literature, and it has been suggested that both general and specific strength training should be part of a climber`s training program. Furthermore, the ability to generate sub-maximal force in different work-rest ratios has proved useful, in examining finger flexor endurance capacity while trying to mimic real-world climbing demands. Importantly, fingers and shoulders are the most frequent injury locations in climbing. Due to the high mechanical stress and load on the finger flexors, fingerboard and campus board training should be limited in lower-graded climbers. Coaches should address, acknowledge, and screen for amenorrhea and disordered eating in climbers. Conclusion Structured low-volume high-resistance training, twice per week hanging from small ledges or a fingerboard, is a feasible approach for climbers. The current injury prevention training aims to increase the level of performance through building tolerance to performance-relevant load exposure and promoting this approach in the climbing field.
