游自由式：手臂要提高，肩膀要露出水面，入水時要伸向前，盡量伸直，潑水成s型，此時必須用力潑水，完成一隻手的動作後，另一隻手重覆先前動作。
當手在水面時，腳踢水要有節拍，如果游短途，二下手六至八下腳。如果游長途，二下手四下腳。
呼吸要訓練，口露出水面不可多，已足夠呼吸便可，因為頭仰起呼吸，會減速，如果游短途，六至八下手一呼吸，如果游長途，四下一呼吸就差不多啦！如果比賽的選手，游50公尺，只呼吸兩三次的。身軀成一直線作為軸心，整個動作要左右平均一致。


Individual Medley (混合四式)
混合四式 (背，蛙，蝶，捷)：有個人混合四式 或 隊際混合四式。
因為游泳比賽場地有在 五十公尺 長池（Long Course）或 在二十五公尺 短池（Short Course）游泳池舉行兩種。
一百米 IM 是 短池（Short Course）二十五公尺 游泳比賽項目其中一項 （因在長池比賽一百公尺是兩次直池、不能準確地使運動員每二十五公尺游泳每一種泳式），正確名稱是 一百公尺個人混合四式，（100 Meter Individual Medley）運動員要在每一次直池 （二十五公尺）游泳一種 國際游泳聯會 認許的泳式，包括： 背、蛙、蝶、捷 合共一百公尺。



Individual Medley (混合四式) : 蝶、背、蛙、捷 四式。
Freestyle 只是其中一種泳式自由式。

Freestyle:
Freestyle is one of the official swimming competitions according to the rules of FINA. However, it is technically not a style, as there are very few regulations about the way freestyle has to be swum. Most swimmers choose to swim front crawl during freestyle, as this style is generally the fastest. In fact, freestyle is often confused to be the same as front crawl, whereas freestyle means any style.
Freestyle swimming competitions can be any of the unregulated strokes such as front crawl, dog paddle, or sidestroke. Individual freestyle competitions can also be swum in one of the officially regulated strokes (breaststroke, butterfly, and backstroke). For the freestyle part of medley competitions, however, one cannot use breaststroke, butterfly, or backstroke. Most competitive swimmers choose the front crawl during freestyle competitions, as this style provides the greatest speed. Freestyle competitions have also been swum completely and partially in other styles, especially at lower ranking competitions. During the Olympic Games, front crawl is swum almost exclusively during freestyle.

Freestyle 係自由式。
Medley 係混合式囉。
哈哈！
