Starts

• Need to be fast and rigid at a straight angle.
• The faster one gets into a straight angle, the
  faster the start is, thus a faster time.
• A good start usually is an acute angle measuring
  30-40 degrees between the water and swimmer.

Streamline Position

• Another necessary straight angle.
• If a swimmer moves their head, it slows them
  down, and creates an unwanted obtuse angle
  between the head and arms.

An impeccable straight angle.
5
Stroke Technique

• In breaststroke, the arms move to a acute angle,
  to a right angle, to a straight angle between the
  upper arm and forearm in a manner of seconds.
• In freestyle, the arms go from an acute angle to
  an obtuse angle in less than a second.

Conclusion

• To be a good swimmer, one must be able to
  demonstrate good angles in their starts,
  streamline position and stroke technique. One
  must also love to sport, and be able to have fun.

With great angles, Michael sweeps another race.
