本研究目的在探討不同等級蛙泳選手聯合、劃手、蹬夾腿和協調效率的差異情形。以臺北市游泳代表隊男性選手24位爲研究對象，經百公尺蛙泳測驗後，依成績優劣順序，分成三個等級，每一等級中有八位選手，幷以重複量數之設計及「對抗平衡法」進行蛙泳聯合、劃手、蹬夾腿三種方式作單位公斤推進功率之測驗。推進功率是以滑輪負重牽引器Power-Rock測試。其結果經分析討論後，得到下列結論： 1.第一級蛙泳選手的推進功率[8.42±0.82^(10-2)kg（上標 w）.M/sec／體重（公斤）]，顯著大於第二級[6.72±0.73^(10-2)kg（上標 w）.M/sec／體重（公斤）]和第三級[5.05±0.90^(10-2)kg（上標 w）.M/sec/體重（公斤）]的蛙泳選手；在協調效率方面，第一級[1.10±0.54^(10-2)kg（上標 w）.M/sec／體重（公斤）]顯著大於第二級[0.02±0.95^(10-2)kg（上標 w）。M/sec／體重（公斤）]的蛙泳選手；顯示較高水準的蛙泳選手不但推進力較大，協調效率也較佳。 2.第二級蛙泳選手如果要晋升爲第一級選手訓練的重點應放在增加協調效率方面，結果顯示第一級選手優於第二級選手的主要原因是在於協調效率的差異。 3.第三級蛙泳後選手如果要晋升爲第二級選手訓練的重點應放在蹬夾腿推進功率方面，結果顯示第二級選手優於第三級選手的主要原因是在於蹬夾腿推進功率的差異。

This study aims to investigate the propulsive force and coordination efficiency of arm strokes (AS), leg kicks (LK) and whole strokes (WS) among breaststroke swimmers of different levels. Twenty-four male swimmers of the Taipei Swimming Team were studied. The subjects were divided into 3 levels, each consists of 8 members, according to their performance in 100-meter breaststroke tests. An identical-subject with repeated-measure design and a balanced-order testing sequence were used. Power-Rack (Total Performance, USA) was used to determine the propulsive force per unit weight for AS, and WS. Results and conclusions are as follows. 1.Level A swimmers generated the highest propulsion (8.42±0.82^(10-2) kgw M/sec/weight), which is significantly greater than the propulsion of Level B(6.72±0.73^(10-2)kgw M/sec/weihgt) and Level C(5.05±0.90^(10-2)kgw M/sec/weight). The coordination efficiency of Level A(1.10±0.54^(10-2)kgw M/sec/weight) is also significantly greater than that of Level B(0.02±0.95^(10-2)kgw M/sec/weight). This indicates that better swimmers can not only generate higher propulsive force but also achieve better coordination efficiency. 2. To be promoted to Level A, breaststroke swimmers in Level B must improve not only the propulsive force of their arms and legs but also their coordination efficiency. The improvement of coordination efficiency is even more important than propulsive force. 3.To be promoted to Level B, breaststroke swinmmers in Level C need to raise the propulsive force not only of their arms but also of their legs, and the latter is more important than the former.
