Abstract

Objectives: This study aims to enhance the orientation and mobility skills of blind students at SLB Tanjung Morawa in 2024. Visual impairments significantly impact the ability of blind children to navigate their surroundings, leading to limitations in orientation and mobility. As an intervention, soccer was utilized as an active movement strategy to stimulate physical engagement and improve students’ spatial awareness, ultimately fostering greater independence in daily activities. Materials and Methods: This study employed a pre-experimental design with a one-group pre-test–post-test approach. The research subjects comprised six blind students with low vision characteristics, selected through purposive sampling based on specific criteria, including the degree of blindness and initial mobility competence. Data collection involved standardized orientation and mobility assessments conducted before and after the intervention. The soccer-based intervention was implemented through structured training sessions. Data were analyzed using non-parametric statistical methods, specifically the sign test, to evaluate the effectiveness of the intervention in enhancing students’ orientation and mobility skills. Results: The findings indicate a significant improvement in the orientation and mobility skills of blind students following the intervention. Pre-test scores ranged from 42 to 75, whereas post-test scores increased to a range of 67 to 90. Statistical analysis revealed a Z_H value of 2.05, exceeding the critical value at the 5% significance level (Z_H = +1.96), leading to the rejection of the null hypothesis. These results confirm that soccer-based intervention has a statistically significant positive impact on the orientation and mobility skills of blind students. Conclusions: The study concludes that soccer-based interventions significantly enhance the orientation and mobility abilities of blind students at SLB Tanjung Morawa. This method presents a viable alternative in special education curricula to improve movement and spatial navigation skills in visually impaired children. Future research should explore the long-term effects of soccer-based training on orientation and mobility development, as well as investigate the integration of other sports-based activities that may yield similar benefits. Additionally, expanding the study to include a larger and more diverse sample, incorporating various age groups and degrees of visual impairment, would provide more comprehensive insights into the efficacy of this approach.

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.
