Article Synopsis
- Eccentric exercise (ECC) is gaining popularity as it enhances muscle performance with lower metabolic demands, but its effects on vascular responses are not fully understood.
- This study analyzed the changes in blood flow patterns and endothelial shear stress (ESS) during ECC at low, moderate, and high intensities using a sample of eighteen healthy individuals.
- Findings revealed that both antegrade and retrograde ESS increased significantly according to exercise intensity, indicating that ECC could help maintain endothelial health and improve blood flow dynamics.
Background: This study aimed to examine the effects of a six-week of concurrent training using high-intensity interval plus resistance training on flow-mediated dilation and pulse wave velocity in hypertensive, elevated blood pressure, or normotensive. A secondary goal was to analyze the inter-individual variability.
Methods: A randomized controlled clinical trial was executed with 60 adult participants distributed across six groups: three control groups of hypertensive, elevated blood pressure, or normotensive and other three experimental hypertensive, elevated blood pressure, and normotensive groups, each comprising n=10 individuals.
Article Synopsis
- This study investigates how intramuscular stiffness in the hamstrings affects muscle strain during passive hip flexion, aiming to understand why strains occur.
- Researchers measured the stiffness of three hamstring muscles in healthy participants and found that the proximal area (closer to the hip) was the least stiff and contributed the most to muscle strain.
- The findings suggest that variations in stiffness within the hamstrings may increase the risk of strain injuries, especially in the proximal region during activities that involve hip flexion.
The aim of this systematic review was to assess the effects of plyometric-jump training (PJT) on the physical fitness of youth with cerebral palsy (CP) compared with controls (i.e., standard therapy).

- Passive hamstring stiffness changes along different parts of the muscle, which can lead to uneven strain during stretching and impact adaptations and injury risk.
- A study with 30 active participants measured the effects of static stretching on the stiffness of three hamstring muscles: biceps femoris, semimembranosus, and semitendinosus, both immediately after stretching and after 4 weeks of stretching or no stretching.
- Results showed that static stretching acutely decreased stiffness in the biceps femoris and semimembranosus but not in the semitendinosus, while chronic effects led to increased stiffness in the biceps femoris and semitendinosus but not in the semimembranosus, suggesting contrasting
