Summary: This study aims to evaluate the effects of static and ballistic stretching on muscle-tendon unit (MTU) stiffness, work absorption, strength, power, and countermovement vertical jump performance. The results showed that acute static stretching reduced work absorption and isokinetic power, while ballistic stretching did not have these effects. The study also found significant positive correlations between MTU stiffness, work absorption, strength, and power. However, neither static nor ballistic stretching affected countermovement vertical jump performance.

Summary: Males have larger blood pressure responses to relative-intensity static handgrip exercise compared with females, but these differences can be abolished by controlling for absolute load (maximal voluntary contraction (MVC)). Sex differences in blood pressure responses during large muscle mass exercise or dynamic contractions vary depending on the intensity, and adjustments for absolute contraction intensity should be considered in cross-sectional comparisons of exercise blood pressure.

Summary: Following 8 weeks of isometric training, improvements in time-dependent measures (RTD, RVD) were observed to reduce power attenuation when ROM is restricted. Additionally, power output was greater in the unrestricted ROM compared to the restricted ROM, with strong relationships between RTD and RVD with peak power.

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: Inertial sensors are affordable and portable devices that can measure postural sway and balance in any setting. Studies have shown their reliability in measuring static standing eyes open and good reliability for dynamic balance. These sensors can distinguish between older and younger adults, as well as fallers and non-fallers, based on various parameters.

Summary: The purpose of this study was to compare the fatigue levels after trail running races ranging from 40 to 170 km. The study found that maximal power output, theoretical maximum force, and theoretical maximum velocity significantly decreased after the races. Dynamic parameters decreased more after longer races. While changes in isometric maximal voluntary contractions were significantly correlated with changes in force and power, the reductions in isometric force were larger than the reductions in power and force.

Summary: This study investigated the neurophysiological mechanisms of balance control in the elderly compared to younger adults during static and dynamic balance tests. The results showed that older adults exhibit different cortical and muscular activation patterns, particularly when cognitive tasks are involved, suggesting the use of preferential motor strategies for postural control. This knowledge could contribute to the development of age-specific rehabilitative and assistive interventions.

Summary: This study aimed to investigate the effects of non-extensible lumbar belts (NEBs) on static and dynamic postural stability. The results showed that NEBs had no significant effect on static postural stability tasks, but significantly improved dynamic postural stability in terms of Y balance test score and dynamic postural stability index (DPSI). These findings suggest that NEBs can enhance dynamic stability in healthy male participants.

Summary: This study examined the variability of isometric force-time characteristics in trained men at different angles. Results showed that there was low intersession variability in isometric peak force and late-stage isometric RFD and impulse measurements, while early-stage RFD and impulse measures had moderate to large variability.

Summary: This study aimed to evaluate the effectiveness of two protocols, slow tempo bodyweight squat combined with an isometric squat (ST-ISO) and an isometric squat alone (ISO), for enhancing jump height. The results showed that the ST-ISO group had decreased performance in the early minutes, but improved significantly in the final minute. However, there was no significant difference in jump height improvement between the two protocols. The study suggests that attention should be given to the rest period after activity and individualized approaches are needed.

Summary: Physical fitness measures, such as boat type, skeletal muscle mass, average power during a 2-minute bench pull test, and vertical jump height, were found to improve the prediction accuracy of race times in young kayak and canoe athletes. Adding these measures to demographic and anthropometric data resulted in better predictions compared to using demographic variables alone.

Summary: This study investigated the associations between biological maturity, body constitution, and physical fitness with rowing performance in young female elite rowers. The results indicated that there were significant correlations between these factors and rowing performance. Specifically, body constitution (lean body mass) and muscular endurance (Bourban test) had the largest explained variance for rowing ergometer performance.

Summary: The study found that foundation strength training is associated with weightlifting performance, suggesting the presence of a general strength component. Weightlifting exercises such as clean and jerk and snatch have a significant correlation with foundation strength exercises like overhead press, front squat, and deadlift. However, more research is needed to determine the effectiveness of using front squats and overhead presses to enhance weightlifting performance.

Summary: This study aims to investigate the combined effects of high-fat diets and exercise training on autophagy in mouse white adipose tissue. The results show that both the high-fat diet and exercise training groups had increased levels of autophagy-related genes and proteins. The combination of high-fat diet and exercise enhances autophagosome formation and modulates lysosomal degradation in white adipose tissue.

Summary: This scoping review examined the effects of balance and resistance training in youth and youth athletes. The findings suggest that sequenced balance and resistance training has a positive impact on balance and muscular fitness in young athletes. However, the effectiveness of metastable resistance training is inconclusive. Further research is needed to investigate the moderating roles of age, maturity status, and sex in these training methods.

Summary: Measuring and adjusting training load is crucial in resistance training to prevent injuries and ensure training effectiveness. This paper presents a novel dataset called PERSIST, which records multiple sensor modalities to predict perceived exertion during resistance training. Researchers can use IMU and ECG data from the dataset to predict perceived exertion.

Summary: This study aimed to examine the immediate and delayed effects of kinesio taping at different stretches on tuck jump performance in active individuals. However, the results showed no improvement in tuck jump performance after the application of kinesio taping, regardless of the stretch level. There were no significant differences in tuck jump performance between the different kinesio taping groups at any time point.

Summary: The purpose of this study was to examine the effects of plyometric jump training (PJT) on lower-limb stiffness. Systematic searches were conducted in PubMed, Web of Science, and Scopus, and the study participants included healthy males and females who undertook a PJT programme isolated from any other training type. The results showed that PJT had a small effect size on lower-limb stiffness, which was optimized with lower volumes (<250 jumps per week) over a relatively long period of time (>7 weeks).

Summary: It has been documented that listening to music can improve physical performance during intense exercise. This study aimed to investigate the effects of listening to preferred music during warm-up or during a test on repeated sprint sets (RSS) performance in adult males. The findings showed better performance in RSS when listening to music during the test compared to no music condition, but no significant effect was found during the second set of the RSS test.
