什么是寬蹬腿

1

寬蹬腿代表性特點是膝蓋外翻,腳掌寬度明顯小于膝蓋寬度,然后向兩邊蹬,之后再夾腿。

什么是窄蹬腿

2

膝蓋內扣,小腿外翻,兩膝外分寬度不應超過肩寬,否則會增大阻力。然后直接向自己的后方蹬去,腿蹬直了,兩條腿也就并攏了,而不是蹬完了再夾,蹬夾一氣呵成。

膝蓋距離不同

3

寬蹬腿和窄蹬腿看上去最大的不同是膝蓋之間的距離不同,寬蹬腿夾水主要靠大腿內側肌肉發力,時間長了容易造成大腿內側肌肉酸痛。

腿部動作不同

4

寬蹬腿翻腳后,倆腳踝距離窄,發力蹬出去的動作是:先向兩邊,蹬直再并攏。夾水幾乎不產生動力。

窄蹬腿翻腳后,倆腳踝距離遠,發力蹬出去的動作是:向后并同時夾在一起,蹬夾同時,夾水產生動力大,游的速度快。
