“…After 48 h, participants underwent 15RM testing and retesting with a rest period of at least 48h between each testing session. Following a RT session, there is a decrease in the function of the neuromuscular and autonomic nervous system that can be restored or increased above baseline value after 48 h ( Chen et al, 2011 ; Kassiano et al, 2021 ). The testing session comprised four exercises, namely squatting (SQ), bench press (BEP), barbell bent-over row (BR), and deadlift (DL).…”

The purpose of this study was to compare blood pressure and heart rate variability responses in physically active men after performing resistance training sessions with rest intervals of 1 min, 2 min and 3 min. Eighteen men (age, 21.6±1.1 years; body mass, 74.1±8.1 kg; body height, 175.3±7.1 cm) who performed 180min of physical activity per week participated in this study. After determining the 15RM loads for the squat, bench press, bent-over row and deadlift, participants performed a resistance training session. Participants performed three resistance training protocols in randomized counterbalanced order. Each experimental protocol comprised different rest intervals between sets of resistance training exercises (1min, 2min or 3min). During each experimental session, participants performed three sets with a 15RM load. Blood pressure and heart rate variability were measured before and for 2h after each session. The results demonstrated a greater blood pressure (p<0.05) reduction with a longer rest interval. There was no statistically significant difference in heart rate variability changes between groups. These results indicate that 2min and 3min rest intervals while using a 15RM load provide the best stimulus for a blood pressure reduction response after a resistance training session. Our findings suggest that strength and conditioning professionals should prescribe 2min or 3min rest intervals when resistance training is performed with a 15RM load if the aim is to obtain an acute reduction in blood pressure after a resistance training session.

“…In this study, we assessed the time domain HRV indices including the square root of the mean squared differences of successive RR intervals (RMSSD) and the standard deviation of the R-R intervals (SDNN). These HRV indices were evaluated before participants engaged in any experimental conditions since it has been consistently reported that low-HRV indices are related to fatigue status (Kassiano et al., 2021; Nakamura et al., 2021).…”

Mental Fatigue From Smartphone Use Reduces Volume-Load in Resistance Training: A Randomized, Single-Blinded Cross-Over Study

We investigated the acute effects of mental fatigue induced by 30-minute use of smartphone social network apps on volume load in resistance training among recreationally trained adults. Sixteen (n = 16) adults of both sexes performed three sets of a half back-squat exercise to failure with 80% of 15RM, interspersed with 3-minutes of passive recovery between sets, before and after two different cognitive tasks: (a) use of smartphone social network apps; and (b) watching a documentary. We assessed mechanical variables and ratings of perceived exertion during the strength exercise. Relative to the documentary-viewing control condition, a 30-minute exposure to smartphone social network apps led participants toward increased perception of mental fatigue ( p = 0.004) and lower volume-load during the strength exercise ( p = 0.006). There were no significant differences in perceived exertion between conditions ( p = 0.54), participants’ motivation ( p = 0.277), intra-set mechanical variables ( p > 0.05), or blood lactate concentrations ( p = 0.36). Our findings of an isolated possible higher-than normal RPE without changes in physiological variables, accompanying the lower volume-load in the mentally-fatigued participants support psychological, rather than physiological, bases for mental fatigue effects.

“…All participants performed the 15RM test in two sessions separated by 48 h to determine the RT loads for experimental protocols. The procedures for this test are described in more detail in Kassiano et al [3]. The resistance training sessions were planned to equalize the volume-load.…”

“…Resistance training is characterized by a systematic organization and manipulation of prescription variables (external load, number of repetitions, muscle action velocity, and rest intervals between sets), adjusted according to each training session objective [1][2][3]. In this context, some set configurations have been adopted to mitigate the reduction in neuromuscular performance, with the premise of optimizing short-and long-term muscular adaptations [4,5].…”

We compared the acute effects of parallel back squat performed from different resistance training configurations on neuromuscular performance. Twenty-eight young adults underwent 4 experimental conditions: inter-repetition rest, traditional, traditional to failure, and rest-pause in the parallel back squat in a randomized, counterbalanced, and cross-over design. The neuromuscular performance was assessed through peak torque of knee extensors and flexors at two angular velocities (90 and 120 º/s) in three moments (before, post, and post-30 min). The peak torque of the knee extensors and flexors at 90 and 120 º/s decreased immediately after training for traditional, traditional to failure, and rest-pause (–8.1% to –17.7%, P<0.001). A greater reduction in the extensor peak torque was found at 120 º/s (P<0.05) in the rest-pause (–17.7%) when compared to traditional (–10.8%). The peak torque returned to baseline values only at post-30 min for the traditional configuration for the knee flexion action at 120 º/s. The peak torque remained similar for the muscular actions and angular velocities for the inter-repetition rest (P>0.05). Our results suggest the inter-repetition rest configuration seems to be a more appropriate strategy for maintaining the lower limb neuromuscular performance after a resistance training session.
