Abstract
Precision, control, and seamless coordination between the eye, nervous system, and musculoskeletal system are essential in the sport of shooting. Foot alignment affects balance and stability, crucial for air rifle shooting. Clarke's angle measures foot alignment. Performance and injury risks to the lower extremity musculoskeletal system in sports can vary based on the diverse midsole characteristics of shoes, including hardness, materials, and structure, influencing their functions. Dominant leg is used to lead out in movement or to manipulate an object and non-dominant leg. The alignment and structure of the foot’s arches, especially the medial longitudinal arch, greatly influence an athlete's capacity to maintain a stable shooting stance. Methodology: A cross-sectional study. In this cross-sectional study, 80 participants (age: 17.78 ± 2.86) 35male and 45 female riffle shooters were included. They were asessed for foot dominance by waterloo footedness questionnaire and Clarke’s angle measurement using static foot print impression. Using ruler and protractor angle was measured. Clarkes angle were obtained of dominant and non-dominant foot and interpretation was made. Results: study found that the significant correlation of clarke’s angle in the dominant and non-dominant foot among air rifle shooters. these findings revealed a statistically significant correlation, with a p-value of < 0.0001, indicating a highly significant relationship. the correlation coefficient (r = 0.88) suggests a strong positive correlation, indicating that the arch of the dominant foot is closely related to that of the non-dominant foot. this suggests that shooters exhibit a balanced foot posture, which may contribute to stability and performance during shooting. Conclusion The study conducted among riffle shooters including participants aging from 12 to 24 years in riffle shooter academy reveals, that there is significant correlation of clarke’s angle in dominant and non-dominant foot in air riffle shooters The results of the study show that among air rifle shooters, Clarke's angle in the dominant and non-dominant foot has a significant positive correlation (r = 0.879). This implies a close relationship between the arch structures of the two feet, which could help with balance and postural stability while shooting. A symmetrical foot position is probably essential for maximizing effectiveness when shooting an air rifle, given the strong connection. These findings emphasize the importance of foot mechanics in sports requiring for precise balance and control. Future research should examine how foot asymmetry affects players' injury avoidance techniques and shooting accuracy.
