Final answer:
Anaerobic exercise increases power and strength.
Step-by-step explanation:
Anaerobic exercise is any physical activity that uses muscles at close to their maximum contraction strength, but for short periods of time. This type of exercise increases muscle and bone mass and strength. Examples of anaerobic exercises include push-ups and sprinting.
During anaerobic exercise, the body breaks down glucose without using oxygen, resulting in the production of lactic acid. This buildup of lactic acid can lead to fatigue.
Therefore, the correct answer to the question is option c) Improved power and strength.
