Hamstring muscle flexibility plays a vital role in functional movement and in the prevention of injuries. Reduced flexibility of the hamstring muscles is common and can lead to biomechanical dysfunctions, a limited range of motion, and poor posture. Interventions such as stretching exercises and myofascial release techniques are widely used to improve muscle flexibility. Dynamic stretching, which involves active muscle movements, has been shown to significantly enhance flexibility and may be more effective than static stretching. The use of a foam roller, which is a self-applied myofascial release technique, also improves flexibility and may offer additional benefits by increasing fascial mobility without impairing muscle strength. Peripheral muscle oxygenation reflects a muscle's ability to utilize oxygen and is increasingly used to assess physical performance and fatigue. Although some studies suggest that stretching exercises and foam roller applications may improve peripheral muscle oxygenation, the evidence remains limited. This study aimed to compare the effects of a single session of isolated dynamic stretching and foam roller application on hamstring muscle flexibility and muscle oxygenation. The hypothesis proposed that dynamic stretching would be more effective than foam roller application in enhancing muscle oxygenation, while both interventions would similarly improve muscle flexibility.

Electrical stimulation has a wide range of clinical applications in rehabilitation, being used for activities such as strengthening, pain control, management of edema, or control of inflammation after injury or surgery. One of the most classic forms of electrotherapy is direct current (DC), which stands out for its particular effects and which are not achieved with other forms of electrical stimulation. A new therapeutic alternative through DC is Percutaneous Microelectrolysis (MEP), which began to have a significant boom in Latin America a couple of years ago. MEP is a minimally invasive procedure in which a low intensity DC is used. MEP has been proposed as a therapeutic resource to reduce muscle contractions and shortenings, thus favoring flexibility, although research to support this effect is lacking. Muscle flexibility is an important component in rehabilitation and training programs. In lower limbs, tightness hamstring muscles is a common condition that limits flexibility and affects sedentary and athletic people. Loss of flexibility of hamstrings has been reported for different sports disciplines, showing a decrease in a high percentage with the exception of sports such as rhythmic gymnastics and dance where flexibility is essential for good performance. Loss of hamstring extensibility has been associated with a higher incidence of muscle tears, patellar tendinopathy, low back pain and alterations in lumbopelvic rhythm associated with compensatory biomechanical changes such as limb shortening, pelvic retroversion, and increased thoracic kyphosis, among others. It is interesting to investigate the effectiveness of MEP in hamstring tightness. A increase in hamstring flexibility can contribute to increased joint range, muscle strength, and lower limb agility.
