Swimming - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-11) |
 | | Swimming pools are popular venues for recreational swimming, as are beaches, lakes, swimming holes, creeks, rivers, and sometimes canals. |
 | | Swimming is also a crucial part of other sports, such as water polo, synchronized swimming, modern pentathlon and triathlon. |
 | | Swimming is an aerobic exercise due to the relatively long exercise times, requiring a constant oxygen supply to the muscles, except for short sprints where the muscles work anaerobically. |
