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: This study examined the impact of different intersession recovery periods on myoelectric activity, fatigue index, and volume load during repeated resistance training session. Results showed that longer than 24 hours recovery period between RT sessions can lead to higher volume load without negatively impacting fatigue index and myoelectric activity for upper body muscles.

Summary: This study analyzed the effect of 12 weeks of core muscle training on core muscle performance in rhythmic gymnasts. The findings showed that core strength training leads to improvements in body composition, trunk strength, and muscle electromyographic activity, which could enhance performance in competitive rhythmic gymnastics exercises.

Summary: This study investigated the effects of fatiguing bilateral dynamic constant external resistance (DCER) forearm flexion on muscle performance fatigability, coactivation, and neuromuscular responses in women. The results showed that fatigue performance was better at low relative loads (30% 1RM), and the initial muscle activity was higher at high relative loads (80% 1RM). Moreover, with increasing fatigue, there were increases in electromyographic (EMG) frequency and mechanomyographic (MMG) amplitude, while MMG frequency decreased. These findings provide insight into the adaptations to training performed at different relative loads.

Summary: This study aims to analyze the coactivation of antagonist muscles in the thigh and ankle in post-stroke subjects during the sit-to-stand task. The results show that the coactivation of ankle joint muscles in post-stroke subjects is more dysfunctional, indicating that the distal segment may more accurately reflect central nervous system dysfunction in post-stroke subjects.

Summary: Previous research has shown that acute caffeine intake can enhance speed and power during bench press exercises. However, this study found that pre-exercise caffeine intake did not affect improvements in 1RM during a 4-week bench press strength training program, but did induce more muscle performance adaptations over a wider range of loads.

Summary: This study compared the cross-transfer of muscle strength between high-load and low-load unilateral resistance training with external pacing of movement, finding that high-load URTEP seemed to enhance the cross-education effect more effectively. However, both approaches were effective in achieving cross-education of dynamic strength after 4 weeks.

Summary: The study aimed to compare the acute effects of different foam rolling periods on lower-body muscles and found that foam rolling did not have any effects on performance, myoelectric activity, and rating of perceived exertion during high intensity resistance training for lower limb exercises.

Summary: The effect of carbohydrate intake on strength training performance has not been systematically analyzed. Acute supplementation and short-term manipulation did not show beneficial effects, while long-term manipulation had inconsistent results. Carbohydrate intake has minimal impact on workouts consisting of up to 10 sets per muscle group, but may benefit performance during higher intensity workouts. More research is needed for further validation.

Summary: This study observed that physically connected pairs modify muscle coactivation to adapt to their partner's performance and visual feedback when tracking a moving target. They skillfully control muscle stiffness to guide arm motion and extract useful information from their partner's movement. This research reveals how humans use muscle activation to obtain accurate information during interaction.

Summary: The study aimed to investigate whether the effects of caffeine intake on resistance exercise and jumping performance are influenced by training status. The results showed that caffeine ingestion improved muscular strength, endurance, and jump height, with similar magnitudes observed in resistance-trained and recreationally active men.

Summary: This study aimed to investigate the association between trunk muscle endurance and change of direction, single leg squat, and power performance in the Special Military Police Force of Rio de Janeiro. The results showed weak associations between single leg squat and trunk extension, as well as right and left side bridge/trunk extensors ratios. The medicine ball throw was weakly associated with the left side bridge/extension ratio. There was a weak negative association between T test performance and the right side bridge/left side bridge ratio. Hip flexion endurance was the only predictor of performance on the single leg squat.

Summary: The study found that passive stretching of the triceps surae in a standing position was more efficient in increasing the myoelectric activity of the lateral head, rather than the medial head. While sitting without passive stretching promoted greater recruitment of the medial head muscle. The length/tension relationship of the gastrocnemius could be utilized as a variable in rehabilitation or conditioning programs.
