Adaptive rowing is a sport for people with physical abnormalities. At present there are many disability peoples interested in this sport. Since the competition in the world championships began in 2002
and Paralympic Games 2008 in Beijing. The competition is divided into three categories: LTA - Legs, Trunk, Arms by athletes can use legs, torso and arms, which is a group of athletes with visual
problems or have impaired brain and the seats can slide like a regular athlete group, TA - Trunk and Arms is the only body and arm unable to use a sliding seat and the last group, AS - Arms and
Shoulders this group body cannot use and unable to use a sliding seat the body will be strap to a seat at the chest level, arms and shoulders so that only use. The key to success in the race is to
make the boat past the distance 1000 meter as fast as possible from the start to the finish line. For adaptive rowing, there are many factors that affect the rowing performance. For example,
adjustments on oar angle will have effect on the boat velocity. Especially The changing style of rowing. Adaptive rowing is the sport which requires a high level of technical. There are several
techniques that make the boat move faster through the water and who is a champion also used a different technique. In adaptive rowing the rowers should use techniques that are most effective.
Therefore the purpose of this paper was to study the difference rowing style (the shape of the force curve) of AS adaptive rowing. Mathematical modeling and computer simulation of adaptive rowing were
developed for study two styles of Thailand national adaptive rower.
The mathematical model includes variables for moving boats such as rowing techniques (the shape of the force curve), boat weight, rower weight, oars angle, oar length, paddle size, and drag
coefficient. The output of simulation is boat velocity.
The Simulation result indicated that when the rower use different style the boat velocity change.
. It is confirmed that if rower use optimal style the boat will move faster.
