Analysis of rhythmic movement techniques in female college long jump athletes: Insights from athletics open
Year: 2025
Type: article
Abstract: This study aims to investigate the kinematic characteristics of the long jump in female college athletes. Video data from 10 Asian female college athletes in the Athletics Open Long Jump Competition were analyzed using high-speed digital cameras with a 240 Hz sampling rate. The captured footage was processed through motion analysis software, with joint markers manually digitized. The results showed that during the rhythmic movement phases, both the horizontal and resultant velocity of the center of gravity and the hip joint angle increase at the heel strike of the swing leg. However, at the toe-off of the swing leg, vertical velocity, angle, and height of the center of gravity decrease, leading to a reduction in flight distance. At the heel strike of the take-off leg, the center of gravity height decreases, and the ankle joint angle increases. At the toe-off of the take-off leg, both the resultant velocity of the center of gravity and the hip and ankle joint angles increase. This method allows coaches to use video analysis to guide athletes in refining their technique, ultimately improving performance and coaching efficiency.
