“…On the other hand, it has been shown that interruption of a set before failure improves mean power or velocity in subsequent repetitions (Lamotte et al ., ; Denton & Cronin, ; Haff et al ., ; Iglesias‐Soler et al ., ). Thus, faster performance may promote lower time under tension and, consequently, shorter periods of obstruction of the arterial flow.…”

“…An alternative set configuration consists of manipulating work and rest periods by breaking sets into small clusters of repetitions. This type of training has been termed cluster training (CT), inter‐repetition rest training or intraset rest loading (Haff et al ., , ; Lawton et al ., ; Hansen et al ., ,b) and has been proposed in order to improve mechanical performance during RE (Haff, ; Haff et al ., , ; Denton & Cronin, ; Hardee et al ., ; Iglesias‐Soler et al ., ), thus increasing mechanical stimuli (Crewther et al ., ; Denton & Cronin, ). Higher mechanical performance (e.g.…”

The aim of this study was to compare the effect of two different high-intensity resistance exercise (RE) set configurations on the following: systolic blood pressure (SBP), rate pressure product (RPP), heart rate (HR) variability (HRV), and HR complexity (HRC). Ten well-trained males performed three parallel squat sets until failure (traditional training; TT) with the four repetitions maximum load (4RM), and a rest of 3 min between sets. Thereafter, participants performed a cluster training session (CT) of equated load but with resting time distributed between each repetition. Dependent variables were recorded before, during, and after RE. Mean SBP (25·7 versus 10·9% percentage increase; P = 0·016) and RPP (112·5 versus 69·9%; P = 0·01) were significantly higher in TT. The decrease in HRV after exercise and the drop of HRC during exercise were similar in CT and TT. Change of standard deviation of normal RR intervals after TT correlated with change in SBP (r = 0·803; P = 0·009) while the change of Sample Entropy during exercise correlated with the increment of RPP during CT (ρ = -0·667; P = 0·05). This study suggests that set configuration influences acute cardiovascular responses during RE. When intensity, volume and work-to-rest ratio are equated, CT is less demanding in terms of SBP and RPP. A greater hemodynamic response during exercise would be associated with a faster parasympathetic recovery.

“…If the percentage of body fat was within 0.05%, the two tests were averaged. A third test was performed and the Set configuration in resistance-training 8 average of the three trials was used for all body composition variables, if the two tests were not within that agreement. The test-retest intra-class reliability for the two tests was excellent with R >0.980 (95% confidence intervals of 0.985 to 0.996).…”

“…In this context and as an effective neuromuscular adaptation for increasing mechanical power in athletes, the National Strength and Conditioning Association advises to train with the maximal movement velocity ending each set with only Set configuration in resistance-training 4 half of the corresponding repetition-to-failure range (34). Conversely, completing every set near or at muscular failure increases both mechanical and metabolic stress which provides an optimal stimulus for increasing muscle mass but with a concomitant decline in movement velocity, a training setting which can be detrimental in sports involving fast actions (8).…”

The present study compared the effects of two weekly-equalized by volume, loading zone and frequency resistance training designs, performed to failure (RTF) or not to failure (NTF), on body composition, strength and mechanical power. Based on individual baseline maximal strength, eighteen recreationally resistance-trained men were pair-matched and consequently randomly assigned to an RTF (n=9) or an NTF (n=9) protocol. Participants trained for 6 weeks using two different routines performed once per week (2 workouts per week). The RTF protocol comprised 4 sets of 10 repetitions per exercise with 2 min rest and the NTF involved 8 sets of 5 repetitions per exercise with 1 min rest. Participants were tested pre-and post-intervention for maximal strength, upper and lower body power, fat-free mass, limb circumferences and muscle thickness. Compared to baseline, both groups improved (p<0.01) the maximal loads lifted in the bench press (RTF +9.44 ± 3.00 kg; NTF +7.22 ± 4.41 kg) and the squat (RTF +9.44 ± 4.64 kg; NTF +11.1 ± 10.33 kg) exercises but only the NTF group increased (p<0.05) upper body power (+15.73 ± 12.59 W). Conversely, only the RTF group showed significant (p<0.05) increase of the elbow flexors (+3.44 ± 5.11 mm) and vastus medialis (+3.28 ± 2.32 mm) thickness while both groups enhanced anterior deltoid thickness (RTF +1.84 ± 1.68 mm, p<0.05; NTF +2.76 ± 2.63 mm, p<0.01). Although both training strategies improved strength, the RTF group elicited better hypertrophic outcomes while the NTF protocol resulted in more favorable improvements for upper body power.

“…Kinematical [48][49][50][51][52][53][54][55] and dynamical [56][57][58] aspects of the system are related to the linear motor's calibration [59,60] that is performed by changing PID parameters and by overlapping the obtained law of motion on the desired one, for a heart rate of 60 beats per minute. When the deviation between two laws is acceptable, durability tests are performed by varying heart's frequency or by setting a random frequency and then by analyzing the heart valve's behaviour.…”

Abstract. The objective of this research is the creation of a testing bench prototype for comparing different types of heart valves, taking into account the variability of some important parameters involved in cardiovascular events. Thanks to performed tests and to obtained data, the comparison between the different valves allows physicians to make the most appropriate choice of heart valve for each patient. The study is still in preliminary stage: it is necessary to do many tests in order to obtain a large amount of data with which it is possible to proceed with the development and implementation of a testing bench stable and easily programmable.
