The Kinematic Analysis On Complete Stroke Cycle Of Rowing Technique Of Lightweight Women Of Elite Athletes

This paper analyzes a complete stroke cycle of rowing technique of lightweight women of elite athletes who took part in the Rowing Spring Championship in QianDaohu, Rowing World Cup Munich and Rowing Championship in Xi'an in 2006. Combining in with the character of technique of elite athletes, it is to comparatively study the rowing technique of lightweight women of elite athletes in competitions in order to show the character of technique of Chinese lightweight women of elite athletes.The result shows that it takes the most time and the least stroke distance in drive prophase, the most stroke distance in recovery later on a complete stroke cycle which includes four phases.Stroke distance and stroke rate are the most important influences on the speed of boat. The most elite athletes performance well in the competition by increasing particularly stroke distance, the other elite athletes won the competition by particularly advancing stroke rate. According to the character of own technique, Athletes who take part in the competitions emphasize particularly on stroke distance or stroke rate to win the competitions. The best method to success is the highest stroke distance based on the high stroke rate.The average speed of all boats in every phases of a stroke cycle show the same curve feature. The average speed of boat is continually growing first, until the maximum, then gradually falling, but very small.In a stroke cycle the minimum speed of boat exists in drive phase, but the maximum exists in recovery phase. The speed of boat is first gradually falling until the minimum, and then gradually increasing until the maximum, decelerating until the starting of next stroke cycle. The second entry speed of boat is larger than the first.Regarding the styles of rowing, there is the fifth style of rowing, besides the Adam style, DDR style, Rosenbery style and Grinko style. According to the exist of the extreme angle of body joint, it divided into four styles. The style shows the individual character and tactics style. Above styles have their own features. Athletes should choose the style that benefit to the requirement of competition and individual trait. The important is to exert one style wonderfully.The stroke rate of National athletes is not perfect. According to the equitable stroke technique, quick drive and slow recovery. Athletes increase the speed of boat through decreasing the recovery time which must be equitable, or it will make boat unstable and keep the speed of boat difficultly.The entry technique after lift of National athletes is not perfect. The drive technique of elite athletes of LW1X and LW2X is very good. But the recovery technique of elite athletes of LW1X is not perfect. National athletes keep the wonderful drive technique and enhance gradually the recovery technique in order to get the best effect.
