Summary: Both velocity-specific and isometric exercises were effective in promoting cervical muscle functions and performance, with no significant differences between the two in various muscle indicators. Velocity-specific exercise demonstrated greater enhancement in neuromuscular efficiency of the cervical extensors.

Summary: Assessing contractile function of skeletal muscle in murine models is commonly employed in laboratory research. This study aimed to characterize the functional properties of hindlimb muscles in different mouse strains. The data reveals both unique differences and similarities between the muscles in different genetic backgrounds. Additionally, the strain of the mouse could potentially influence the measured biological outcome and interact with any genetic manipulation or therapeutic intervention. Therefore, careful consideration of the genetic background and documentation of the strain of mouse is critical in experimental design and publication.

Summary: This study compared the effects of Nordic hamstring exercise (NHE) variations with different hip range of motion on the muscle-tendon unit (MTU) and fascicle function. The results showed a decoupling between fascicle and MTU length during the exercise, with hip flexion resulting in longer lengths of the MTU and fascicles. This suggests that the stretch of the elastic tissue of the MTU plays an important role in energy absorption during NHE.

Summary: Optimizing body composition with higher muscle and bone mass is crucial for maintaining metabolic activities and preventing various diseases. Poor dietary quality, especially in resource-limited settings, can negatively affect health due to high cereal intake and low animal protein consumption. In addition, deficiencies in vitamin D and calcium are prevalent. Improving diet quality and providing adequate supplementation can improve body composition, enhance overall health, and prevent metabolic diseases in young women in developing countries.

Summary: This study compared muscle swelling after low-intensity torque-matched isometric exercises at long and short muscle-tendon unit lengths. The results showed that active torque was significantly lower in the group trained at long lengths, but muscle swelling occurred in both groups. The study suggests that exercise at long muscle-tendon unit lengths can cause similar muscle swelling as exercise at short lengths, even with lower active torque production.

Summary: This study aimed to investigate the performance of critical torque (CT) in terms of sex and skeletal muscle mitochondrial level. The results showed no significant differences in CT and performance fatiguability between sexes, but some protein markers of mitochondrial content correlated positively with CT and performance fatiguability. These findings contribute to a better understanding of muscle metabolism and gender differences.

Summary: The study investigates the impact of reallocating time spent in different intensities of physical activity (PA) on sarcopenia risk in older adults. The results show that reallocating sedentary time to at least light-intensity PA is significantly related to a lower sarcopenia risk score (SRS), even after adjustment for PA type and protein intake. Similarly, reallocating time in light- to moderate-to-vigorous-intensity PA is also related to a lower SRS. These findings emphasize the importance of displacing sedentary behaviors for more active pursuits in older adults to alleviate age-related deterioration of muscle health.

Summary: The study found that menthol applied topically to the skin improves perception and increases force generation. Nine trained male subjects were tested after spraying menthol on their legs during different weightlifting tasks. The results showed an improved performance in the isometric and dynamic lifting tasks after the application of menthol.

Summary: This study aimed to determine muscle strength and fatigue in patients with ALS performing a unilateral exercise, and according to sex and type of ALS. The results showed more accentuated fatigue in men than in women, between the first and last contractions performed and especially on the dominant side. In addition, there was evidence of a coactivation effect on the muscles around the work joint. These findings support the use of systematic and extensive resistance exercise as a non-invasive option for maintaining the functional capacity of patients with ALS.

Summary: This study compared sex-related differences in knee extensor size, torque-velocity relationship, and fatigue resistance adaptations to 12-week SIT. The results showed that SIT significantly increased fatigue resistance and quadriceps muscle cross-sectional area similarly in men and women, but did not significantly affect torque in either gender.

Summary: The study found that downhill running led to a decrease in running economy which lasted for several days, but this decrease was not strongly correlated with a decline in muscle function. This suggests that strength loss is not a key factor affecting running economy.

Summary: This study aimed to investigate the HRV and HR kinetics during cycling exercise in different intensity domains. The results showed significant differences in HR between Delta 30 and Delta 60, with HRV markers accelerating at higher intensities. The findings suggest distinct cardiac autonomic response times for HR and HRV markers in various intensity domains.

Summary: The study found that muscle size and maximal strength have different influences on the parameters of the hyperbolic torque-time to task failure relationship, with larger muscle size and strength prolonging τ(IET') during intermittent isometric exercise. Additionally, muscle perfusion and O-2 delivery limitations play a significant role in defining the torque-time to task failure relationship.

Summary: After performing loaded resistance exercise, known as post-activation performance enhancement (PAPE), explosive performance is increased. This study investigated the effects of plyometric exercise on sedentary young men and found that PAPE disappeared after plyometric exercise induced minor muscle damage, but counter movement jump (CMJ) height increased during the recovery period, exhibiting a priming effect.

Summary: In experienced male runners with varying maximal oxygen uptake, aerobic parameters such as VO(2)max and vVO(2)max, running economy, blood lactate response, oxygen uptake kinetics, and critical velocity can predict endurance running performance. However, for well-trained runners, this relationship seems to be influenced by the duration of the race.

Summary: The study highlights the lack of understanding in eccentric cycling intensity continuum and emphasizes the importance of describing physiological responses based on maximal exercise capacity. It also notes the limited evidence on acute physiological and chronic adaptive responses to eccentric cycling, suggesting the need for further research in this area.
