• Skeletal muscle

• Smooth muscle

• Striated muscle

Which type of muscle is attached to bones and helps in voluntary movements?

• Cardiac muscle

• Skeletal muscle

• Smooth muscle

• Involuntary muscle

What is the primary function of muscle fibers in the body?

• To store energy

• To control physical forces within the body

• To produce hormones

• To transport oxygen

Which type of exercise uses oxygen to create energy?

• Anaerobic

• Aerobic

• Isometric

• Plyometric

What is a characteristic of anaerobic exercise?

• Low intensity, long duration

• Uses slow twitch muscle fibers

• Absence of oxygen

• Improves cardiovascular health

Which type of muscle fibers are primarily used in aerobic exercises?

• Fast twitch muscle fibers

• Slow twitch muscle fibers

• Intermediate twitch muscle fibers

• No muscle fibers

What benefit is associated with anaerobic exercise?

• Reduces cholesterol

• Builds strength and lean muscle mass

• Improves cardiovascular health

• Reduces diabetes

What does "Iso" mean in the context of muscle contraction?

• Different

• Equal

• Strong

• Short

In isotonic contraction, what happens to the tension in the muscle?

• Tension increases

• Tension decreases

• Tension stays the same

• Tension disappears
