Summary: This study compared the effects of machine resistance training and elastic band resistance training on muscle adaptive remodeling. It found that elastic band resistance training increased myofibrillar protein synthesis in young males, but had limited effects in older males. Further research may be needed to optimize training programs for both age groups.

Summary: B-ultrasound measurement can quantitatively reflect muscle strength following gracilis transfer, and CR value could be a potential indicator for functional recovery of the transplanted gracilis muscle. Patients with higher CR1 values had better muscle strength and range of motion compared to those with lower CR1 values.

Summary: This study proposed a force-invariant intent recognition method based on muscle synergy analysis, which was found to significantly outperform traditional pattern recognition methods in accuracy under different force levels. Although there was a drop in classification accuracy among amputee subjects, the proposed method still holds potential for clinical applications.

Summary: The study aimed to assess the validity and reliability of a low-cost hand-held push dynamometer in measuring compressive forces in different ranges. The results showed that the dynamometer had excellent consistency and agreement, as well as high correlation and determination coefficients. The device was found to be a valid method for assessing knee isometric strength, with portability, cost-effectiveness, and user-friendly interface.

Summary: Higher levels of physical activity and reduced sedentary behavior in older adults are associated with better upper and lower body muscle strength and muscle power. These associations are particularly significant in the chair stand test.

Summary: This study combined a full-body musculoskeletal model with dynamic optimization theory to predict the biomechanics of maximum-speed sprinting and evaluate the effects of changes in muscle-tendon properties on sprint performance. The results showed that sprint performance was most sensitive to changes in muscle strength and least affected by changes in tendon compliance. Additionally, muscle fascicle length had a greater impact on sprint performance compared to muscle intrinsic maximum shortening velocity.

Summary: This study systematically reviewed the effects of exercise order on muscular strength and hypertrophy through meta-analysis, finding that starting with multi-joint exercises can increase dynamic muscular strength, and starting with single-joint exercises may be preferable for single-joint exercises. Both exercise order sequences could produce similar results for muscle hypertrophy.

Summary: This review evaluates the literature on the rate of force development scaling factor (RFD-SF), including its physiological mechanisms, assessment protocols, practical application, and other factors. The findings suggest that RFD-SF is sensitive to impairments associated with aging and neurological diseases, but its importance for athletes and its relationship with fatigue and sex are less clear.

Summary: The study investigates the impact of progressive whole-body hyperthermia on maximal and rapid voluntary torque production, indicating that late-phase voluntary rate of torque development is reduced under hyperthermic conditions, likely due to decreased neural drive and reduced maximum voluntary torque. In contrast, early-and middle-phase voluntary rate of torque development are unaffected by hyperthermia due to conflicting effects of reduced neural drive and faster intrinsic contractile properties.

Summary: This study aimed to evaluate the immediate clinical effects of superimposing EMS on strength training compared with conventional exercise in healthy non-athletic adults. The results showed that EMS was more effective in stimulating muscle contractions compared to conventional training. This suggests that EMS may be a safe and reasonable modality for improving physical fitness in healthy individuals.

Summary: This study investigated the effects of acute repeated hypoxia-hyperoxia preconditioning on resistance exercise-induced muscle damage in male athletes. The results showed that alternating hypoxic/hyperoxic air preconditioning could attenuate muscle soreness and damage after exercise, but had no effect on muscle strength recovery.

Summary: The study demonstrates that acute beetroot juice supplementation significantly improves mean and peak power output of muscles during half-squat movements, whether in concentric or eccentric phases. These findings contribute to understanding the impact of beetroot juice supplementation on skeletal muscle contractile function and its potential implications for enhancing muscle power output in sports performance.

Summary: The study aimed to investigate whether initial muscle-damaging exercise could confer a protective effect between different muscle groups. Results showed that, relative to the control group, the experimental group exhibited an exacerbating damaging effect on knee flexor isometric strength following the second exercise bout.

Summary: The study demonstrates that combined resistance and endurance training can improve muscle strength, reduce fatigue, alleviate depression, and enhance quality of life in individuals with MS. The effects of the training persisted even after cessation, indicating its potential preventive role in disease-related deterioration of muscular performance and quality of life.
