Abstract

This study aims to analyze the relationship between biomechanical and physiological variables on sprint performance in short-distance runners. A total of 20 male athletes aged 18–21 years were the subjects. Biomechanical data were obtained through video analysis of sprint movements, including stride length, stride frequency, joint angles, and foot contact time. While physiological aspects were measured through vertical jump tests and Running-Based Anaerobic Sprint Test (RAST). Sprint times at distances of 30 and 60 meters were used as performance indicators. The results showed a significant correlation between stride length, foot contact time, cold muscle strength, and anaerobic capacity with sprint time (p <0.05). A negative correlation was found in stride length and muscle strength, while foot contact time showed a positive correlation. These findings confirm that sprint efficiency is greatly influenced by a combination of good biomechanical techniques and optimal physiological capacity. The conclusion of this study is that the development of an effective sprint training program must include an integrated approach between movement technique training and physical condition, to optimize running performance to the maximum.

Review

The paper "Optimalisasi Performa Sprint: Tinjauan Biomekanika dan Fisiologis" effectively investigates the critical interplay between biomechanical and physiological factors influencing sprint performance in short-distance runners. By analyzing data from 20 male athletes, the study successfully identifies key variables such as stride length, foot contact time, muscle strength, and anaerobic capacity as significant determinants of sprint speed. The findings underscore the multi-faceted nature of sprint efficiency, establishing that both optimal movement technique and robust physical capacity are indispensable for achieving maximal performance. This research provides a valuable framework for understanding the complex components contributing to sprint success and offers important insights for professionals in sports science and coaching. Methodologically, the study adopted a clear approach by collecting both biomechanical data via video analysis (e.g., stride length, foot contact time) and physiological data through established tests like the vertical jump and RAST. The identification of specific correlations, such as the negative relationship between stride length/muscle strength and sprint time, and the positive relationship with foot contact time, represents a significant strength. However, the abstract could benefit from a clarification of the term "cold muscle strength," which appears to be a mistranslation and likely refers to general muscle strength measured by the vertical jump. Further methodological details, such as the specific joint angles analyzed, the reliability and validity of the video analysis protocol, and a more explicit mention of the statistical methods used beyond the p-value, would enhance the paper's transparency and enable more comprehensive critical assessment. The study's conclusion, advocating for an integrated training approach that combines movement technique and physical conditioning, is a practical and well-supported outcome of its findings. This implication holds significant relevance for sports practitioners and coaches, emphasizing the need for holistic training programs that avoid isolated skill or strength development. Future research could expand upon these findings by investigating causal relationships through intervention studies, exploring potential gender differences in these correlations, or examining the specific impact of various training modalities on the identified biomechanical and physiological markers. Overall, this paper provides a solid foundation for understanding the intricate determinants of sprint performance and offers clear guidance for optimizing training interventions.
