Additional factors affecting the muscular system

Question 1

How does age affect the muscular system?

Answer 1

As you get older, muscle mass decreases.

The onset of this muscle mass loss begins around the age of 50 and is referred to as sarcopenia. Muscles become smaller resulting in a decrease in muscle strength and power.

Question 2

How does cramp affect the muscular system?

Answer 2

Cramp is the sudden involuntary contraction of your muscle. The sensation of muscle spasm where you have no control of the tightening of the muscle fibres can be painful and can be prompted by exercise. The muscles of the lower leg are particularly susceptible to cramp during exercise. Cramp can last from a few seconds up to 10 minutes. Dehydration due to lack of blood flow to the muscles is the most common factor causing cramp.
