Summary: This study aimed to compare the effects of unilateral stretching intervention programs with two different intensities on range of motion, muscle stiffness, and muscle architecture. The results showed that high-intensity static stretching significantly increased the range of motion of the non-trained limb, while low-intensity static stretching had no significant effect. However, there were no significant changes in muscle stiffness and muscle architecture in both groups.

Summary: This study investigated the acute and chronic effects of static stretching at different intensities on flexibility. The results showed that stretching at 120% intensity led to significantly greater acute improvements in ROM, peak passive torque, and stiffness compared to stretching at 100% intensity. Additionally, four weeks of stretching increased ROM and peak passive torque but did not decrease passive stiffness, regardless of the stretching intensity.

Summary: Static stretching reduces maximal muscle force generation and also affects the generation of precise levels of force during submaximal contractions. In this study, the effect of acute static stretching on knee extensor force control was investigated. The results showed that prolonged static stretching led to decreased maximal force and increased fluctuations in force at moderate to high intensities, indicating negative effects on force control tasks.

Summary: The study aimed to investigate the acute effects of high-intensity jack-knife stretching on hamstring flexibility. Results showed that the stretching significantly increased knee extension ROM and passive torque at end ROM at both intensities. However, muscle-tendon unit stiffness decreased significantly only in the PODmax intensity, suggesting the method is effective in reducing stiffness but may cause discomfort during stretching.

Summary: High-intensity static stretching (HI-SS) is more effective than low-intensity (LI-SS) for increasing range of motion and decreasing muscle stiffness of the plantar flexor muscles in young men after a 4-week training period. However, neither HI-SS nor LI-SS training led to changes in muscle strength, jump height, or muscle architecture. The control group did not show significant changes in any variables.

Summary: Previous studies have shown that longer-duration static stretching interventions can decrease muscle strength and impair muscle control function. This study found that three 60-second static stretching interventions increased knee flexion range of motion but impaired explosive muscle strength and muscle control function up to 20 minutes after the intervention.

Summary: This study aimed to investigate the acute effects of prescribed and applied loads of static stretching on muscle-tendon unit stiffness. The results showed that high and moderate intensity static stretching decreased muscle-tendon unit stiffness, while low intensity stretching had no significant effect. The applied load of static stretching was found to be an important factor in decreasing muscle-tendon unit stiffness in low and moderate intensity stretching.

Summary: This study aimed to determine the factors associated with the time required for return to play (RTP) among young athletes with early-stage lumbar spondylolysis receiving conservative treatment. The factors investigated included spondylolysis laterality, symptom duration, lower-extremity flexibility, treatment interval, patient adherence, and residual lower back pain (LBP). The results showed that patient adherence to physician orders, treatment interval, and spondylolysis laterality directly contributed to shortened RTP.

Summary: This study built prediction models for the Post-COVID-19 Functional Status (PCFS) scale using sociodemographic data, clinical findings, lung function, and muscle strength. The results showed that worse general fatigue and handgrip strength were associated with more severe physical function impairments in patients with post-COVID-19 syndrome. Additionally, a history of prior hospitalization resulted in worse physical function. Prediction models incorporating objective measures can better assess the physical function of these patients and aid in the selection of candidates for a physical reconditioning program.

Summary: This study investigated the effect of scapular dyskinesis on pitching kinetics in the shoulder joint of baseball players. The results suggest that scapular dyskinesis causes an increase in anterior force during pitching, leading to excessive external rotation and insufficient posterior tilt of the scapula, which may result in shoulder injuries.
