Abstract

Introduction: Hurdle events represent a complex athletic discipline requiring the integration of speed, power, technical skill, and specific physiological adaptations. Despite extensive research on sprint events, limited studies have comprehensively examined the multifaceted physiological demands specific to hurdle competitions. Purpose of the Study: This study aimed to investigate the physiological adaptations in endurance, strength, and flexibility among hurdle athletes and determine the correlations between these parameters and competitive performance. Materials and Methods: Twenty-four hurdle athletes (age: 17.2 ± 1.1 years) from SMA Negeri 2 Medan, Sumatera Utara, participated in this correlational study. Participants underwent comprehensive physiological assessments including VO₂max testing, isokinetic strength measurements, and flexibility evaluations. Performance data were collected from official competition records over a 12-month period. Results: Significant correlations were found between hurdle performance times and maximal oxygen uptake (r = -0.68, p < 0.01), lower limb power output (r = -0.74, p < 0.001), and hip flexibility measures (r = -0.56, p < 0.05). Athletes demonstrated superior anaerobic power (738.4 ± 67.2 W) and enhanced range of motion in hip flexion (118.7 ± 8.4°) compared to age-matched controls. Conclusions: Hurdle events demand specific physiological adaptations encompassing aerobic capacity, explosive power, and enhanced flexibility. These findings provide evidence-based guidelines for targeted training interventions in hurdle athletes.

Abstract

Purpose of the study: This research aimed to investigate the effectiveness of drill method training on improving starting technique and 100-meter running performance among elementary school students at SD Negeri 064006 in Medan City. Materials and Methods: A quasi-experimental study was conducted with 60 elementary school students (ages 10-12 years) randomly assigned to experimental (n=30) and control (n=30) groups. The experimental group received 8 weeks of structured drill method training focusing on starting technique, while the control group followed conventional physical education instruction. Pre- and post-intervention measurements included starting reaction time, 30-meter split time, and total 100-meter sprint time. Results: Significant improvements were observed in the experimental group compared to the control group. Starting reaction time improved from 0.65±0.12s to 0.48±0.09s (p<0.001), 30-meter split time decreased from 6.8±0.7s to 5.9±0.5s (p<0.001), and 100-meter total time reduced from 18.2±1.4s to 16.1±1.1s (p<0.001). The control group showed minimal improvements (p>0.05). Conclusions: The drill method training significantly enhanced starting technique and 100-meter running performance in elementary school students. This structured approach can be effectively implemented in physical education curricula to improve fundamental movement skills and athletic performance.
