Exercise Science Flashcards

Which muscle group is the primary driver of the breaststroke kick?

Answer: Hip adductors and quadriceps

The whip kick sweeps the legs together with the adductors and extends the knees with the quadriceps.

Which ankle action is needed for an effective flutter kick?

Answer: Plantar flexion

Which sign suggests a swimming student may be developing hypothermia?

Answer: Shivering and blue lips

Increasing the distance of a swim set gradually from week to week applies which principle?

Answer: Progressive overload

What is the most common trigger of muscle cramps during swimming?

Answer: Fatigue and overexertion of the muscle

Cramps most often come from muscle fatigue, often worsened by dehydration or cold water.

Why can swimmers become dehydrated even though they are in water?

Answer: They still sweat and lose fluid through breathing

Swimmers sweat and lose fluid through respiration, which often goes unnoticed in the water.

Which component of fitness is most improved by regular stretching routines for swimmers?

Answer: Flexibility (range of motion)
