“…Furthermore, immediately after the walking exercise, the participant was asked to express their perception of fatigue as a value based on the Borg scale (0 < 20). On a different day, each participant was assessed with regard to their maximal repetitions during the leg-press exercise (Padulo et al, 2017;Migliaccio et al, 2018) and the 1-RM based on the Brzycki method was calculated at the same time (Padulo et al, 2015). To ensure standardization of the procedure the following method was used.…”

The use of music during training represents a special paradigm for trainers to stimulate people undertaking different types of exercise. However, the relationship between the tempo of music and perception of effort during different metabolic demands is still unclear. Therefore, the aim of this research was to determine whether high intensity exercise is more sensitive to the beneficial effects of music than endurance exercise. This study assessed 19 active women (age 26.4 ± 2.6 years) during endurance (walking for 10 at 6.5 km/h on a treadmill) and high intensity (80% on 1-RM) exercise under four different randomly assigned conditions: no music (NM), with music at 90-110 bpm (LOW), with music at 130-150 bpm (MED), and with music at 170-190 bpm (HIGH). During each trial, heart rate (HR) and the rating of perceived exertion (RPE) were assessed. Repeated analysis of variance measures was used to detect any differences between the four conditions during high intensity and low intensity exercise. RPE showed more substantial changes during the endurance exercises (11%), than during high intensity exercise (6.5%), between HIGH and NM conditions. The metabolic demand during the walking exercise increased between NM and HIGH bpm conditions. This study indicates the benefits of music under stress conditions as well as during endurance and high intensity training. The results demonstrate that the beneficial effects of music are more likely to be seen in endurance exercise. Consequently, music may be considered an important tool to stimulate people engaging in low intensity physical exercise.

“…Furthermore, a significant relationship was observed between the RPE and SFI. These results indicated that RPE could be used as an exercise fatigue predictor, which makes sense because RPE integrates more physiological-related information induced by resistance exercises [ 18 , 34 ]. Conventionally, RPE is measured upon completion of required sets and/or sessions, as represents of subjective feelings of discomfort overall [ 25 , 41 ].…”

“…The relationship between RPE, velocity loss, and SFI during exercise was examined using Spearman’s correlation analysis. The non-overlapping part of the three conditions was used in the correlation analysis [ 28 , 34 ]. Statistical significance was acceptable at p < 0.05 in all analyses.…”

The rating of perceived exertion (RPE) scale has been found to reflect physiological responses, and this study aimed to assess the validity of using the Borg CR-10 scale and velocity loss to evaluate muscle fatigue quantified by surface electromyography during back squat (BS) exercise. A total of 15 collegiate male athletes underwent three non-explosive BS tasks comprising low, medium, and high volumes at 65% of their one-repetition maximum. RPEs, spectral fatigue index (SFI), and velocity loss during BS exercise were assessed throughout the trials. Significant differences in overall RPE (p < 0.001) and average SFI (p < 0.05) were observed between the conditions, whereas no significant difference was observed in average velocity loss. Significant increases in RPE and SFI (p < 0.001) were observed within the exercise process, whereas a significant increase in velocity loss was not observed. Correlation analyses indicated a significant correlation between RPE and SFI obtained during exercise (r = 0.573, p < 0.001). However, no significant correlation was observed between velocity loss and SFI. These results demonstrated that RPE could be used as a muscle fatigue predictor in BS exercise, but that velocity loss may not reflect muscle fatigue correctly when participants cannot and/or are not required to perform BS explosively. Furthermore, practitioners should not use velocity loss as a muscle fatigue indicator in some resistance exercise situations, such as rehabilitation, beginner, and hypertrophy programs.

“…A linear encoder (Ergotest Innovation AS R , Linear displacement sensor SKU 1260 MuscleLAb System, Norway) connected to an integrated data analysis system was used (Ergotest Innovation AS R , MuscleLAb System, Norway). The speed was used to calculate mean and maximum power using the Musclab R as described previously (Padulo et al, 2015a(Padulo et al, , 2017Migliaccio et al, 2018;Santos et al, 2018).…”

Research regarding the relationship between core muscle endurance and performance is limited. The purpose of this study was to analyze the association between core/trunk endurance and athletic performance. Seventy-four healthy participants between 18 and 45 years old participated in this study (Age: 26.0 ± 6.5 years; Mass: 74.6 ± 12.8 kg; Height: 1.74 ± 0.08 m; BMI: 19.0 ± 6.8 kg/m 2). The core endurance was measured using the McGill protocol, consisting of the following tests: trunk flexion, back extension, and side-bridge. Functional performance was evaluated with push-ups, sit to stand, T-run test, countermovement jump (CMJ), Yo-Yo test, maximum dynamic strengthone repetition maximum (1RM) and muscle power on the bench press, pull row, and leg press. The regression results between the McGill protocol (proxy for core/trunk endurance) and the dependent variables were: 1RM pull row: r 2 = 0.109 with p = 0.046; RM bench press: r 2 = 0.149 with p = 0.012; RM leg press: r 2 = 0.144 with p = 0.013 and power pull row: r 2 = 0.151 with p = 0.016; power bench press: r 2 = 0.136 with p = 0.026; power leg press: r 2 = 0.122 with p = 0.013), push-ups: r 2 = 0.157 with p < 0.001, sit to stand: r 2 = 0.198 with p < 0,001), functional movement score: r 2 = 0.209 with p < 0.001). Nevertheless, core endurance scores were not able to predict jump ability (r 2 = 0.014, p = 0.807) or agility (T-test: 0.036 with p = 0.497). In conclusion, core endurance exerted no significant influence the agility and jump performance but influenced the ability to run intermittently, exert maximum power and strength in different actions (push, pull, and lift exercises) related to the better quality of movement (FMS).
