Does using a swimming cap make a swimmer swim faster?Featured science projectScience project video


This experiment was done to investigate if using a swimming cap can help a swimmer swim faster.


Using the swimming cap will help to increase the speed of the swimmer and he will be able to swim the 100m dash in a shorter time.

The swimming cap

The type of swimsuit a swimmer wears is important. Whether or not a swimmer wears a swimming cap is an important consideration as it affects his performance. A cap protects a swimmer’s hair from the chlorine in the pool. But more importantly, it improves the performance of a swimmer because it reduces the amount of drag/resistance.

There are many designs of swimming caps. Caps come in all sizes and colors. They are normally made of polyester, latex, nylon, silicon or Lycra. Competitive swimmers usually wear latex caps because such caps fit the head snugly. Competitive swimmers who are allergic to latex materials can use silicone swimming caps. Although silicon swimming caps are more expensive than latex ones, they are more durable and last longer.

Some swimming caps come with a chin strap. Such caps are suitable for swimmers who have long hair. Wearing a cap will ensure that their hair does not shift while they swim. Insulated swimming caps should be used when swimming in cold water. Swimming caps help us to maintain our body temperature. They reduce fatigue and help prevent us from falling ill.
