Abstract: Efficient long-distance running depends on well-coordinated joint movements, especially during the landing and take-off phases. This study aimed to compare the joint angles of the ankle, knee, hip, and shoulder during running on a grass track versus a treadmill. Ten male athletes (aged 19–25 years, height 170–183 cm, weight 58.6–68.9 kg) from Aligarh Muslim University participated. Each athlete ran 750 meters on both surfaces recorded by a high-speed camera (Canon Legria HF S10, 1/1200 shutter speed, 50 Hz). Joint angles were measured during the landing and take-off phases using Silicon Coach Pro software. paired t-test was used to identify significant differences between the two surfaces. Results showed significant differences in ankle and hip angles at take-off, and shoulder angles during both landing and take-off. However, knee and hip angles during landing did not differ significantly. These results suggest that running surface affects certain joint movements, especially at the shoulder and ankle. Understanding these differences can help coaches and athletes tailor training strategies to improve performance and reduce injury risk.
