in my hometown, dogstyle is a kind of freestyle but with head always above
the surface of water.
It is a freestyle, but keeping your head above the surface of water.
So you don't need to change breath.
You can swim longer and faster.
When you rescue other people, it shows its power and usability.
Freestyle is just a show, and it is useless in real swimming.

发帖数: 45267 | 11 你到底会不会游泳？脸埋在水里比水上速度快，只是不能持久，所以埋头划五六下抬头
呼吸是比较常见的。奥运会应该还规定了运动员头在水里待的时间的上限，不然大家的
成绩还要提高一截

发帖数: 1877 | 13 自由泳其实也不是完全自由。速度最快的泳姿其实是潜泳，像海豚式的摆动身体前进。
这种姿势几乎部产生水花，所以效率最高，速度也是最快的。游泳比赛对这种泳姿有严
格限定，比如连续摆动的次数不能太多。

发帖数: 415 | 21 From Wikipedia:
Freestyle means "any style" for individual swims and any style but
breaststroke, butterfly, or backstroke for both the individual medley, and
medley relay competitions. The wall has to be touched at every turn and upon
completion. Some part of the swimmer must be above water at any time,
except for the first 15 metres after the start and every turn. This rule was
introduced (see History of swimming) to prevent swimmers from using the
faster underwater swimming to their advantage, or even swimming entire laps
underwater. The exact FINA rules are:
Freestyle means that in an event so designated the swimmer may swim any
style, except that in individual medley or medley relay events, freestyle
means any style other than backstroke, breaststroke, or butterfly
Some part of the swimmer must touch the wall upon completion of each length
and at the finish
Some part of the swimmer must break the surface of the water throughout the
race, except it shall be permissible for the swimmer to be completely
submerged during the turn and for a distance of not more than 15 metres
after the start and each turn. By that point the head must have broken the
surface[3] |
