Summary: This systematic review investigates the long-term neurophysiological adaptations to strength training. Findings suggest that strength-trained individuals exhibit greater maximal voluntary activation and reduced muscle activity during submaximal tasks. They also show lower co-contraction of antagonist muscles, and global intermuscular coordination plays an important role in long-term strength training adaptations.

Summary: Despite the well-known pathophysiologies associated with COPD, resistance training led to improvements in lower-limb muscle strength, muscle mass, muscle quality, and endurance performance in COPD subjects, resembling or exceeding responses seen in healthy controls. These findings highlight the largely unrecognized responsiveness of COPD patients to resistance training and suggest it as a potent measure to relieve disease-related impairments.

Summary: This study aimed to evaluate the feasibility of the surface electromyography (sEMG) parameters for estimating muscle mass. The results showed that sEMG parameters were positively correlated with maximal voluntary contraction strength, segmental lean mass, and appendicular skeletal muscle mass, but negatively correlated with segmental fat mass. Under controlled conditions, sEMG parameters can represent overall muscle strength and muscle mass in healthy individuals.

Summary: The current study aimed to compare the effects of volume-equated training frequency on muscle mass and strength gains. The results showed that there were no significant differences in muscle growth or muscle strength between different training frequencies when the weekly training volume was equal.

Summary: This study developed a new method to determine the spatial distribution of muscle fibers within human motor units using a flexible multi-channel electrode and a deconvolution method. The results demonstrated that human motor units spatially overlap and provided data on the spatial arrangement of muscle fibers.

Summary: All three resistance training programs led to significant improvements in muscle strength and endurance, with the 10% velocity loss group showing greater gains in vertical jump and sprint performance. This suggests that the magnitude of velocity loss in each exercise set can significantly influence training adaptations.

Summary: The study found that home-based weight-bearing squat training can improve lower limb function in older adults and performance in physical functional tests related to activities of daily living. Additionally, such training benefits older adults regardless of whether squats are shallow or deep.

Summary: This study investigated the effects of high-intensity exercise training on muscle-specific hypertrophy in females, finding increases in muscle strength and cross-sectional area after training. Individual changes in the slope of the motor unit action potential amplitude versus recruitment threshold relationship were moderately to strongly correlated with changes in muscle cross-sectional area and whole leg skeletal muscle mass.

Summary: This study investigated the effects of performing resistance training (RT) before endurance training (ET) and subsequent molecular adaptations. The results showed that RT improved body composition and strength, but did not provide additional benefits to ET adaptations. Moreover, prior RT seemed to impair mitochondrial adaptations to ET.

Summary: The study found that the rest-pause method slightly outperforms traditional resistance training in improving strength, but the hypertrophic adaptations are similar between the two. Muscle thickness in the proximal and middle parts of the quadriceps increased in all training groups, while there was no significant change in the distal part. Although modest, the effect sizes tended to favor the rest-pause method.

Summary: High-frequency BFR training can generate significant neuromuscular adaptations, but strength declines and muscle fiber atrophy were reported in resistance training to failure. There is a lack of studies comparing low-frequency and high-frequency in short-term BFR training. Comparisons between resistance exercises of similar intensities are also lacking, limiting conclusions on the specific effects of proximity to failure or BFR.

Summary: Resistance-based blood flow restriction training (BFRT) and heavy-load resistance training (HLRT) have similar effects on muscle strength and size, activating similar anabolic pathways. However, BFRT leads to minor muscle hypertrophy, suggesting that strength adaptation is primarily driven by neurological adaptation.

Summary: The study compared neuromuscular activation in different exercises for the gluteus maximus, biceps femoris, and erector spinae, finding that the Romanian deadlift and Roman chair back extension were more effective in activating the gluteus maximus, while the Roman chair had superior activation of the biceps femoris. The erector spinae activation did not differ significantly among the three exercises.

Summary: The study found no association between leisure time physical activity changes and subsequent BMI changes, whereas BMI change predicted subsequent physical activity change. These findings suggest that BMI change predicts subsequent physical activity change at the population level and not vice versa.

Summary: This study compared the effects of a 12-week upper/lower split training program and a full-body resistance training program on strength, muscle mass, and explosive characteristics. The results showed that there were no significant differences between the two programs in terms of maximal strength, muscle mass, and explosive muscle strength. Both programs led to improvements in these measures.

Summary: This study investigated the effects of different loads on the barbell back squat. The findings showed that increasing loads led to a decrease in barbell displacement and velocity in the sticking region, an increase in external hip extensor moment, and a decrease in hip and knee extension and myoelectric activity.

Summary: The study provides precise information on the physical work demands of home care workers in Norway, showing that they spend half of their workday sitting and the rest in various physical activities. The study also highlights the need for preventive measures due to the significant variation in physical workloads among home care workers and the high cardiovascular load during work.

Summary: This study compared the acute effects of performing a lower body resistance training program in one long or two shorter sessions in 1 day on training volume and affective measures. The results showed that a longer training session led to higher perceptions of effort, discomfort, and session pleasure, while shorter sessions resulted in greater training volume.

Summary: This study aims to alleviate musculoskeletal pain and sick leave among home care workers by redistributing work schedules to achieve a more balanced physical workload. The intervention will be tested using a cluster randomized controlled trial design, and outcomes such as musculoskeletal pain, physical behaviors, and fatigue will be assessed. The study also includes a process evaluation to gather qualitative data on the implementation of the intervention.

Summary: The study aimed to assess the physical work demands of onshore petroleum maintenance workers using body-worn sensors, in order to close the knowledge gap based on self-report. The findings showed that although on average half of the workday was spent sitting or lying down, the remaining work time involved long durations of arm elevation and forward bending. There was substantial variation in these work exposures among workers, indicating the need for preventive measures in work organization and performance.

Summary: This study evaluates the cost-effectiveness and cost-benefit of inpatient multimodal occupational rehabilitation (I-MORE) compared to outpatient acceptance and commitment therapy (O-ACT) for individuals sick listed due to musculoskeletal- or common mental disorders during two years of follow-up. Results show that despite higher healthcare costs, I-MORE is cost-effective due to lower production loss. Based on economic arguments, I-MORE should be implemented as a treatment alternative for individuals on long-term sick leave. Rating: 8 out of 10.

Summary: The study found that adding a workplace intervention to inpatient occupational rehabilitation did not significantly increase return-to-work self-efficacy. Participants with high self-efficacy scores at the end of rehabilitation had fewer sickness absence days in the future, indicating that self-efficacy is associated with work participation.
