Abstract:

This study aims to analyze the level of selected physical and physiological capacities and their relationship with digital performance in the 400-meter hurdles event among second-year students of the College of Physical Education and Sports Sciences at the University of Diyala. The importance of the study stems from the fact that the 400m hurdles is a combined event requiring a high degree of integration between speed, strength endurance, and the functional efficiency of the cardiovascular and respiratory systems, making the assessment of these capacities essential for diagnosing and improving performance.

The experimental method was employed using two groups, experimental and control, consisting of (80) students. The experimental group underwent a specialized six-week training program that included speed drills, strength endurance exercises, and high-intensity interval training (HIIT), while the control group continued with their regular program. The measurements included strength endurance, speed endurance, post-exercise heart rate, heart rate recovery time, vital capacity, oxygen saturation, blood pressure, and the digital performance of the 400m hurdles.

The results revealed a significant improvement in all variables for the experimental group compared to the control group. Strength endurance improved by (19.59%), speed endurance by (29.82%), and performance time decreased by (-9.21%). Additionally, there was a meaningful reduction in post-exercise heart rate and recovery time, along with improvements in vital capacity and oxygen saturation, indicating enhanced functional efficiency. Correlation analysis also showed significant relationships between the physical and physiological capacities and digital performance, with strength endurance and speed endurance being the most influential variables.

The study concludes that the implemented training program was effective in developing the physical and physiological capacities necessary for optimal performance in the 400m hurdles. It further suggests that physical and physiological measurements can serve as predictive indicators of performance. The researcher recommends integrating field-based physiological assessments into training curricula and adopting training approaches that emphasize the interaction between muscular and functional capacities.
