“…The standard checklist has 27 items, which refer to: reporting (items 1-10); external validity (items 11-13); internal validity (items 14-26); and statistical power (item 27). However, given the specificity of included studies (i.e., exercise interventions), we added two items that refer to reporting of compliance (item 28) and supervision of the exercise programs (item 29), as done by others [29][30][31]. With the adjusted checklist, the maximum score was 29 points.…”

“…With the adjusted checklist, the maximum score was 29 points. The following classification was used for scoring the studies: (1) good methodological quality (>20 points); (2) moderate methodological quality (11-20 points); and (3) poor methodological quality (<11 points) [29][30][31]. Two authors (JG and FS), independently performed the quality assessment, and any observed differences were resolved via discussion and agreement.…”

“…The rest interval can be operationally defined as the time taken between sets. Traditionally, rest intervals are spent passively (i.e., without any additional physical activity) and therefore, most of the current recommendations for rest intervals exclusively focus on its optimal duration (American College of Sports Medicine, 2009;Grgic et al, 2018). Mohamad et al (2012) highlighted that in an RT session comprising six to eight exercises performed for three to four sets with a rest interval of 60-90 s, the total amount of time spent in rest is ∼24-40 min per session.…”

We aimed to investigate the effects of resistance training (RT) combined with noload isometric actions (iso-holds) during the inter-set recovery period versus RT that involves passive inter-set rest on muscular strength, muscular hypertrophy, and muscular endurance in resistance-trained men. Twenty-seven resistance-trained male volunteers were randomly assigned to either a traditional group (TRAD) that performed a hypertrophy-oriented RT routine with the rest intervals spent passively (n = 13) or to a group that supplemented traditional RT with iso-holds (ISO) for the working muscle group between each set (n = 14). Training for both routines consisted of three weekly sessions performed for 8 weeks. Three sets of 8-12 repetitions were performed per exercise. A 2-min rest interval was afforded between sets; the ISO group performed iso-holds for the first 30 s of each rest interval and then recovered for the final 90 s. Maximal strength was assessed using the one repetition maximum (1RM) tests in the leg press and bench press. Upper-body muscle endurance was assessed by performing the bench press to failure at 50% of 1RM. Muscle thickness (MT) of the elbow flexors, elbow extensors, mid-thigh, and lateral thigh was assessed using B-mode ultrasound. Results indicated a favorable effect of ISO on MT in the mid-thigh. Alternatively, there was a possible detrimental effect for ISO on leg press strength. No other notable differences were seen between conditions. In conclusion, the use of inter-set iso-holds may be a time-efficient strategy to enhance development of the quadriceps femoris; conversely, it may be detrimental to maximizing lower body strength.

“…Mitochondria not only generate energy for cells but also induce oxidative stress and apoptosis if ROS accumulation; hence cells develop multiple mechanisms to maintain the mitochondrial OXPHOS [9]. OXPHOS within mitochondria is an important metabolic process whereby electrons are transferred through the electron transport chain across the inner mitochondrial membrane to reduce oxygen into water.…”

Objective: Mitochondrial impairment in the skeletal muscle contributes to useless of limbs in spleen qi deficiency; however the genesis of such impairment is not clear. Herein, PTEN-induced putative kinase 1 (PINK1)-Parkin pathway and mitophagy were studied to explore the machinery of mitochondrial impairment. Methods: 16 male SD rats were randomly divided in the control group and spleen qi deficiency group (model group); transmission electron microscope was used to observe mitochondrial morphology; mitochondrial oxidative phosphorylation was assessed by testing mitochondrial membrane potential (MMP) and levels of ATP and ROS; western blot was used to analyze expressions of PINK1, Parkin, microtubule-associated protein 1 light chain 3-II (LC3-II) and p62. Results: Compared with those in the control group, mitochondria became small, less and scattered, MMP and the ATP level were reduced, the ROS level was elevated, PINK1 expression was decreased, p62 expression was increased, but Parkin and LC3-II expressions were not altered, in the model group. Conclusions: Suppression of mitophagy might be related to the mitochondrial damage in the skeletal muscle when spleen qi deficiency develops.
