Differences between male and female in tennis and handball techniques

Sport technique of handball throws and tennis shots is important but also very difficult. Fortunately, high-speed video/camera technology provides a new way to study technique. In this study, two handball players (24 year old female and 25 year old male) and two tennis players (21 year old female and 22 year old male) were recorded by two synchronized video cameras doing three handball throws and three tennis shots. The recordings were to allow for capturing of three dimensional space acts, which is real and understandable for each sport performance. Three dimensional biomechanical analyses with Simi motion 3D software measures the exact values of kinetic parameters, including trajectories, angles, velocities and accelerations of each body segment. These main segments (points, joints) were taken into consideration: head, left arm, right arm, left elbow, right elbow, left wrist, right wrist, left hip, right hip, left knee, right knee, left ankle, and right ankle. In addition, two racket positions and the tennis ball were added and analyzed. All attempts by each tennis player were similar. Differences between tested tennis players were visible while some similar characteristics were observed. Higher sport performance is associated with better kinetic parameters.
