Q

What are health-related fitness components?

A

Health-related fitness components have been identified as those that are more important to health than to athletic or sporting ability.
These are aerobic capacity, anaerobic capacity, muscular strength, flexibility and body composition.

Q

What is anaerobic capacity?

A

The ability of the body to produce energy without using oxygen and hence the efficiency/power of the two anaerobic energy systems~ the
ATP-PC and anaerobic glycolysis systems.

Q

What is muscular endurance?

A

The ability of the muscle or muscle group to perform repeated contractions (concentric, eccentric, or isokinetic) for an extended period of time, or to maintain a contraction for an extended period of time (isometric contraction).

20
Q

What are factors affecting reaction time?

A

Optimal arousal and concentration
Number of responses
Noise

21
Q

What is agility?
