Swimming

Today i would like to intro a sports,swimming.

In competitive swimming, four major styles have been established. 

 

These have been relatively stable over the last 30–40 years with minor improvements. 

 

The four main strokes in swimming are

 

Freestyle,

 

This swim style is also the most common and has longer distances,

 

 such as 1500M or the 1650 yard swim.

 

 

Breaststroke,

Some people refer to breaststroke as the "frog" stroke

 

for your body moves like a frog swimming in the water.

 

 The stroke itself is the slowest of any competitive strokes

 

 and thought to be the oldest of all swimming strokes.

 

 

Backstroke,

 

The swimming style is similar to an upside down front crawl. 

 

Both backstroke and front crawl are long-axis strokes.

Butterfly stroke,

the butterfly is a more difficult stroke that requires good technique as well as strong muscles
