“…The current study's findings revealed a similar trend of decreasing velocity from set to set with no difference between barbells. Considering that previous research on resistance training has shown that velocity loss may objectively quantify neuromuscular fatigue ( de-Oliveira et al, 2022 ; Sánchez-Medina and González-Badillo, 2011 ), it indicates that bench pressing with either a cambered or a standard barbell contributes to a similar increase in fatigue with each successive set. This confirms that using a cambered barbell may not require longer rest intervals between sets.…”

“…The cambered barbell's U-shape provides greater torso room and allows to reach a lower-end position of the barbell in the bench press movement in comparison to the standard barbell (Matykiewicz et al, 2021). One of the cambered bar's tenets is to help athletes extend their chest and shoulder muscles to a greater extent during the bottom phase of the bench press movement (Corey, 1991).…”

“…In addition, none of those studies were designed to compare the effects of bench presses on immediate and delayed fatigue, despite the fact that the ROM may have an impact on its magnitude. However, in the study by Krzysztofik et al (2021) , changes in barbell velocity, which is considered an indicator of neuromuscular fatigue ( de-Oliveira et al, 2022 ; Sánchez-Medina and González-Badillo, 2011 ), were assessed. Those authors compared the velocities obtained during successive sets of standard and cambered barbell presses until failure and found a similar decrease in peak velocity from set to set.…”

The objective of this study was to compare the impact of cambered and standard barbells used during the bench press exercise on the number of performed repetitions and mean velocity during a bench press training session that included 5 sets performed to volitional failure at 70% of one-repetition maximum (1RM) (for each barbell type). An additional objective was to determine whether there would be any difference in neuromuscular fatigue assessed by peak velocity changes during bench press throws performed 1 and 24 hours after the cessation of each session. The research participants included 12 healthy resistance-trained men. Participants performed 5 sets of the bench press exercise to volitional failure against 70% of 1RM with the cambered or standard barbell. The Friedman’s test showed an overall trend of a significant decrease in the mean velocity (p < 0.001) and a number of performed repetitions (p < 0.001) from the first to the fifth set (p < 0.006 and p < 0.02, respectively for all) under both conditions, yet neither bar showed significant differences between the corresponding sets. Two-way ANOVA indicated a significant main effect of time (p < 0.001) for peak velocity during the bench press throw. The post-hoc comparisons showed significantly lower peak velocity during the bench press throw one hour after the bench press compared to pre (p = 0.003) and 24-hour post intervention (p = 0.007). Both barbells caused a similar decrease in peak barbell velocity during the bench press throw performed one hour after the bench press training session, with values returning to baseline 24 hours later. This indicates that bench press workouts with either a standard or a cambered barbell present the same training demands.

“…Within the realm of research, there exist inquiries aimed at scrutinising the immediate impacts of these training configurations ( Gómez-Landero and Frías-Menacho, 2020 ), with a particular emphasis on factors such as fatigue levels associated with these methodologies ( De-Oliveira et al, 2022 ). Despite the difficulty in defining and controlling the training stimulus, given the variable characteristics of the programs ( Mangine and Seay, 2022 ), we will focus on the strength exercises that are usually part of these programs.…”

“…Despite the difficulty in defining and controlling the training stimulus, given the variable characteristics of the programs ( Mangine and Seay, 2022 ), we will focus on the strength exercises that are usually part of these programs. In this regard, the vast majority of the studies analyse the effects on similar absolute loads or, failing that, relative loads established with respect to the value of 1RM ( Maté-Muñoz et al, 2018 ; Silva-Grigoletto et al, 2020 ; De-Oliveira et al, 2021 ; De-Oliveira et al, 2022 ), which can present serious limitations ( Sanchez-Medina and González-Badillo, 2011 ; Elvar-Heredia et al, 2021 ; Maté-Muñoz et al, 2022 ). Thus, propulsive velocity has been identified as the most precise variable for evaluating the intensity of strength exercises ( Sanchez-Medina et al, 2010 ; Sanchez-Medina and González-Badillo, 2011 ).…”

Introduction: In recent years, a surge of interest in high-intensity training methods, associated with “cross” modalities has emerged as a promising approach for improving performance and overall health. Therefore, the main aim of this study was to compare the acute effects on heart rate, mean propulsive velocity and intra and inter-set velocity loss in “Cross” modalities.Materials and methods: Twelve athletes, 10 men’s and 2 women’s (age: 31.5 ± 6.74 years; height: 174.17 ± 6.05 cm; weight: 75.34 ± 7.16 kg) with at least 1 year of experience in “cross” training. The participants performed three different “cross” modalities, Rounds for Time (RFT), Every Minute on the Minute (EMOM) and As Many Rounds As Possible (AMRAP) across three separate days. In each modality participants carried out 10 repetitions of squat, pull-ups, and shoulder press with difference rates of work-rest. Mean propulsive velocity (MPV) and heart rate (HR) were recorded and analysed for each athlete. Repeated measures one-way ANOVA and repeated measures two-way ANOVA were performed to analyse the differences between modalities and subjects. Besides, a Bonferroni post hoc analysis was carried out to assess the differences between modalities in each subject.Results: Significant differences in MPV were observed among the modalities. The comparisons between RFT and AMRAP, as well as EMOM and AMRAP, revealed lower MPV in the AMRAP modality (p < 0.01). RFT exhibited the greatest intra-set velocity loss, while EMOM showed the least, with significant distinctions (p < 0.01) between them. Furthermore, significant differences in the HR results were noted among all modalities (p < 0.05).Conclusion: Findings consistently identify the AMRAP modality as having the lowest MPV values due to its prolonged duration, promoting self-regulated tempo for optimal performance and technique, while the RFT modality exhibits higher fatigue and intra-set MPV losses. These insights into propulsive velocity, intensity, fatigue, and pacing across various “Cross” modalities provide valuable guidance for athletes and trainers seeking to enhance their exercise programs.
