Tonga at the 2011 Commonwealth Youth Games: Tonga competed in the 2011 Commonwealth Youth Games held in the British Crown Dependency of Isle of Man from 7 to 13 September 2011.  Their participation marked their second Commonwealth Youth Games appearance.  The delegation of Tonga consisted of three officials and four competitors (two men and two women) participating in three different sports— athletics, boxing and swimming.  This was a decrease in the number of athletes from the nation's last appearance at the Games, when nine athletes were sent to the 2008 Commonwealth Youth Games in Pune.  Heamasi Sekona won a bronze in the light heavyweight class of boxing without winning a single bout.  Sekona was the only medalist from Tongan side.  None of the rest three athletes advanced past the qualifying stages, and thus did not win any medals.  Katiloka ranked eighth overall in the qualifying round for triple jump; middleweight boxer, Pomale, lost to Cody Crowley of Canada in his first round match.  Additionally, Prescott ranked 18th and 13th in the heat rounds of 50 m and 100 m backstroke events respectively.  Sekona's was the first medal for Tonga in the history of the Games.

She specialized in 100 metres hurdles, Long Jump, Pentathlon, and once held national records in all the three and high jump and heptathlon.

Women's pentathlon: The pentathlon or women's pentathlon is a combined track and field event in which each woman competes in five separate events over one day (formerly two days).  The distance or time for each event is converted to points via scoring tables, with the overall ranking determined by total points.  Since 1949 the events have been sprint hurdling, high jump, shot put, long jump, and a flat race.  The sprint hurdles distance was 80 m outdoors until 1969 and thereafter 100 m; in indoor pentathlon the distance is 60 m.  The flat race was 200 m until 1976 and thereafter 800 m.  In elite-level outdoor competition, the pentathlon was superseded in 1981 by the heptathlon, which has seven events, with both 200 m and 800 m, as well as the javelin throw.  Pentathlon is still contested at school and masters level and indoors.

110 metres hurdles: The 110 metres hurdles, or 110-meter hurdles, is a hurdling track and field event for men.  It is included in the athletics programme at the Summer Olympic Games.  The female counterpart is the 100 metres hurdles.  As part of a racing event, ten hurdles of 1.067 metres (3.5 ft or 42 inches) in height are evenly spaced along a straight course of 110 metres.  They are positioned so that they will fall over if bumped into by the runner.  Fallen hurdles do not carry a fixed time penalty for the runners, but they have a significant pull-over weight which slows down the run.  Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks.

Themis Zambrzycki: Themis Zambrzycki (married name Glatman) (born October 20, 1960) is a retired Brazilian multi-sport athlete.  She was the 1976 South American Junior Champion in the long jump, shot put and  pentathlon, plus the silver medalist in the 100 metres hurdles.  In 1977 she competed at the senior level South American Championships, taking silver in the hurdles, long jump and pentathlon.  In 1979, she won the long jump and pentathlon, with a silver in the shot put.

Lloyd Cowan: Lloyd Cowan (born 8 July 1962) is a former British track and field athlete, who specialised in the 110 and 400 metres hurdles.  He was selected for the 1984 Los Angeles Olympics, but he could not go because of illness; competed at the 1994 Commonwealth Games and won his last medal at the AAA nationals in 1999.  He retired from athletics at the age of 39 and now coaches 18 athletes, including Christine Ohuruogu, the former 400 metres Olympic, World and Commonwealth Champion; Simeon Williamson, the former British 100 metres champion; and Andy Turner, the former European and Commonwealth 110 metres hurdles champion.

100 metres hurdles: The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women (the male counterpart is the 110 metres hurdles).  For the race, ten hurdles of a height of 83.8 cm are placed along a straight course of 100 m .  The first hurdle is placed after a run-up of 13 metres from the starting line.  The next 9 hurdles are set at a distance of 8.5 metres from each other, and the home stretch from the last hurdle to the finish line is 10.5 metres long.  The hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous.  Fallen hurdles do not count against runners provided that they do not run into them on purpose.  Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks.

Athletics at the 2004 Commonwealth Youth Games: At the 2004 Commonwealth Youth Games, the athletics events were held at the La Trobe University Athletics Complex in Bendigo, Australia from 2–3 December.
