“…Muscle strength is usually defined as the maximum force or torque of a particular muscle group developed during maximal voluntary contraction under a given set of conditions (Jaric, 2003). Some measurement procedures (tests) in addition to maximum strength and torque, also include rate of force development (RFD), which refers to the muscle's ability to develop maximum force in a shorter period of time (Wilson & Murphy, 1996;Andersen & Aagaard, 2006;Haff et al, 2015;Aravena-Sagardia et al, 2021;Krzyszkowski et al, 2022).…”

“…Today's technology allows us to measure the contractile characteristics of the most important muscle groups that relate to maximum strength, explosiveness, power, endurance, etc., as well as precise measurement of body composition, where absolute protein and muscle measurements can be defined along with segmental data (Kukic et al, 2018;Aravena-Sagardia et al, 2021).…”

The aim of this study was to determine the sensitivity of different methods of partialization, in terms of different body component indices in relation to indicators of strength and explosiveness. The research involved 187 subjects who were divided into two groups based on sex. This research consisted of measuring body composition characteristics by multichannel bioimpedance analysis (BIA) InBody 720, as well as contractile characteristics of different muscle groups with tenziometric Dinamometry method. Based on the results of the factor analysis we found that regardless of the sex the most sensitive variable for partialization of absolute body isometric strength variable (ABiS) is partialization by allometric scaling (0.964 for females and 0.947 for males explained factor variance). However, in the case of absolute body isometric explosiveness (ABiE), the results of this study have demonstrated that partialization relative to skeletal muscle mass according to the body longitudinality -skeletal muscle mass index (SMMI) is the methodological choice disregarding the sex (0.982 for females and 0.980 for males explained factor variance). The results of the study have shown that for the purpose of scaling the maximal strength relative to body composition, the allometric method can be considered as a choice, while for the partialization of maximal isometric explosiveness skeletal muscle mass index is the best choice insensitive of the sex.

“…This would supposedly occur due to the minimization of the effect of fatigue to the detriment of the optimization of the partial resynthesis capacity of muscle phosphocreatine, making it possible to increase the training volume, maintenance of force generation, and movement velocity for a longer time and, consequently, the increase in muscle mass 7,11,12 . However, the literature has demonstrated both the superiority 7,[13][14][15] and the disadvantage 16,17 of the clusterset system compared to the traditional training system, as well as similarities in their results 18 . The lack of consensus is based, among other factors, on the different configurations of the ISI used in the studies.…”

“…This has been verified in the literature studies that adopted ISI between 2.85 s 14 and 130 s 13 . However, intermediate ISI values (10 s to 40 s) seem to be more frequently used [16][17][18][19] . Most studies did not adopt clear criteria for choosing the magnitude of the ISI and only Ho et al (2021) 18 investigated the effects of two or more protocols with different ISI.…”

Objective: To compare the acute effect of two training protocols until concentric failure (CF) with different intra-set interval (ISI) configurations (20 s and 40 s) on total weight, the total number of repetitions, and time under tension in trained subjects. Methods: Ten men participated in the study (age = 25.1 ± 4.4 years; body mass = 76.5 ± 10.4 kg; height = 175.8 ± 9.3 cm). Two protocols were performed with 4 sets of bench press exercises and differentiated by the ISI: i) Protocol ISI-40 (40 s) - each set consisted of 6 repetitions followed by an ISI of 40 s and completed with repetitions up to CF; ii) Protocol ISI-20 (20 s) - each set consisted of 6 repetitions with ISI of 20 s every 3 repetitions followed by repetitions to CF. The intensity was 10 repetitions maximum, and the rest interval between sets of 80 s. A minimum interval of 48 h was adopted between protocols. Results: There was no significant difference in the number of repetitions (p = 0.074), in the time under tension (p = 0.353) and in the total volume (p = 0.083) between the protocols. Conclusion: The results indicate that the different ISI configurations did not distinctly influence the number of repetitions, time under tension, and total volume.
