Effect of Dynamic Neuromuscular Stabilization (DNS) training on endurance and flexibility in adolescent sprinters - A Randomized Control Trial

This study aims to evaluate the impact of Dynamic Neuromuscular Stabilization DNS on endurance and flexibility in adolescent sprinters. DNS is based on developmental kinesiology principles and focuses on restoring innate stabilization patterns through core activation, intra abdominal pressure regulation, and coordinated muscle function. Sprinting demands high levels of biomechanics, neuromuscular control, and core stability, which are often challenged during adolescence due to rapid growth and physiological changes.

Current sprint training emphasizes power and speed but may overlook neuromuscular imbalances and flexibility deficits, increasing the risk of injuries such as hamstring strains. DNS addresses these deficits, potentially improving performance, injury prevention, flexibility, and endurance. Despite evidence in adults and college athletes, DNS effects remain underexplored in adolescent athletes.

This randomized controlled trial will recruit 36 adolescent sprinters aged 10 to 18 from schools and athletic clubs in Belagavi. Participants will be randomly assigned to an experimental group performing DNS exercises or a control group following a standard exercise program, each for 30 minutes three times a week for eight weeks.

Outcome measures include the Back Saver Sit and Reach Test for assessing flexibility of hamstrings, Yo Yo Endurance Test to assess endurance, and chest expansion measurement to assess respiratory function and thoracic mobility. Data will be analyzed using appropriate statistical tests depending on normality.

The expected result is that DNS training will significantly improve endurance and flexibility compared to standard exercises, offering a targeted approach for adolescent sprinters to optimize performance and reduce injury risks.
