Muscle Physiology and Training Effects

How does aerobic training affect the heart?

• It makes the heart weaker.

• It thickens and strengthens the left ventricular wall.

• It decreases the heart's efficiency.

• It reduces the heart size.

What happens to haemoglobin levels with increased training?

• They decrease.

• They remain the same.

• They increase.

• They fluctuate randomly.

What does VO2 Max refer to?

• Maximum heart rate

• Maximum oxygen uptake

• Maximum blood pressure

• Maximum muscle strength

What type of muscle fibers are associated with explosive movements?

• Slow twitch

• Fast twitch

• Intermediate twitch

• Static twitch

What is muscle hypertrophy?

• Decrease in muscle size

• Increase in muscle size

• No change in muscle size

• Muscle atrophy

What does C.O. stand for in the context of cardiac output?

• Cardiac Output

• Circulatory Output

• Cellular Output

• Capillary Output

What happens to the heart muscle with aerobic training?

• It undergoes atrophy.

• It undergoes hypertrophy.

• It remains unchanged.

• It becomes less efficient.

What is the primary function of the heart in the context of training?

• To decrease blood flow

• To pump blood

• To store blood

• To filter blood

What is the primary function of the heart as a muscle?

• To decrease blood pressure

• To undergo hypertrophy and increase strength

• To reduce oxygen uptake
