ABSTRACT
The purpose of the study was to establish the data of motion in different degree college rower. According to the data to establish the regression model that will be applied to assess different degree of rowing technique. In the experiment, bjects (includes collage’s students, players of ROC, players who obtain medals of world’s games) are forty-eight rowers who are age 22.39±1.72 years old, weight 60.44±10.29 Kilos, height 178.81±7.48 cm. The study analyze the motion of rowers in the ConceptⅡ by motion analysis systems and ConceptⅡ rowing systems. We set the of the video camera Shutter speed is 1/500, the frames speed is 30Hz, and the distance from camera to rowers is 15 meters, the stroke of the ConceptⅡ is set 30-31 times for one minute, and the air resistance is set on the level of 5, the rowing distance is 500 meters. The eleven body landmarks (includes head, shoulder, elbow, wrist, oar, hip, knee, ankle, heel, toe and chair) were digitized with the software of the Peak Motus 7.0,and the and body center of mass were estimated by using the Jin-cherng Wang data (1999), and the data of Fourier number were got through the Fourier series analysis. SPSS is tryout the efficient parameters and establish forecast model, and then we could authenticate the degree of the rowers.
The results of study show that we could use the efficient parameters [includes the Hand of first number (H1), Hand of second number (H2), wrist of second number (W2), knee of second number (K2), gravity of second number (M2), relative angle 0f hip joint third number (RH3)] and stepwise regression model (D=2.210 - 1.071H1 - 2.279 H2 - 5.630 W2 + 15.335 K2 + 7.907 M2 + 0.08025RH3) to predicate the degree of rowing technique for the collage’s students in Taiwan.
Key words：Biomechanics, Rowing, Fourier series, Degree, Technique.
