Water Sports are sports that involve water. The categories are based on the relation of the sports to the water. Some of the sports include only one part related to swimming, as for example Triathlon. In-the-water sports include: Swimming which includes pool swimming and open water swimming; Triathlon is usually a combination of swimming, cycling and running; Modern pentathlon includes épée fencing, pistol shooting, swimming, a show jumping course on horseback, and cross country running; Rescue swimming is swimming with the goal to rescue other swimmers; Water polo is a team sport played in water; Synchronized swimming is a hybrid of swimming, gymnastics, and ballet; Water aerobics is aerobics in the water; Water gymnastics is gymnastics in the water; Snorkeling is the practice of swimming at the surface (typically of the sea). Underwater sports include scuba diving and underwater rugby. On-the-water sports include water skiing, rowing, rafting, jet ski racing, and kayaking. University Rowing in the United Kingdom began when it was introduced to Oxford in the late 18th century. The first University Boat Race (between Oxford and Cambridge) was held in 1829. Today, many universities have a boat club and at the collegiate universities, Oxford, Cambridge, Durham, and London, each college has its own club as well as a main university club. Most universities compete in the British Universities & Colleges Sport (BUCS) Championships with a number of events over the year. For non-indoor events, boats are separated into Championship (where \"[BUCS] points\" are available) , Intermediate and Beginner (for students in their first year of the sport). As of June 16, 2008, UCS (who represented the professional staff working in the sector) and BUSA (the lead body for competitive sport in the sector) have merged to form \"BUCS\" - British Universities & Colleges Sport. Events from 2008/09 onwards therefore come under the BUCS banner, rather than BUSA, e.g., BUCS Regatta. College Rowing is one of the oldest intercollegiate sport in the United States. However, rowers comprise only 2.2% of total college athletes. This may be in part because of the status of rowing as an amateur sport and because not all universities have access to suitable bodies of water. In the 2002-03 school year there were 1,712 male and 6,690 female collegiate rowers. This is compared to the 2,037 male and 2,049 female high school rowers who competed in the 2003-04 school year. Collegiate men\'s rowing consists of two squads, a varsity and a freshman team. The varsity squad typically fields a Varsity Eight (8+), a Second Varsity or Junior Varsity Eight (8+) and a \'\"Freshman\" (8+), but can also field additional Varsity or Frosh boats. Women rowers compete at the NCAA Rowing Championships in a Varsity 8, a Second Varsity 8, and a Varsity Four. Most teams also field one or more Novice Eights for novice rowers who have never competed at the collegiate level.
