Type one was dressed inswimming pants, type two was dressed in long training wear and sports shoes, and type three wasdressed in shirts with long sleeves, winter jacket, long pants and sports shoes.
The results were as follows.
The Breaststroke was easy to swim putting on every type of wear and was supposed to be the beststroke for dressed swimming. The Sidestroke was difficult to swim in the three types of wear and wassupposed to have no strong point of the three kinds of strokes.
