Singapore government does not actually support the national
athletes. So they will go through the normal BMT and be posted like
any other boys.
For example, the national waterpolo team, the boys actually
volunteered for the training after work. The team is only formed
during competition times.They will collect the names and
registered.
For Martial Arts such as muay thai, TKD, wushu, a selection is
held near the SEA games. The uncles will decide who shall go.
For Bodybuilding, winner of the national championship will
ultimately respresent Singapore.
There is no official national team for soccer, volleyball or
whatever. They are actually "volunteers".
However, a lot of people know how to keng, especially when you
are sportsmen. Frequent injuries are common. They will usually end
up as clerk, in SAFSA and always training.
