GCSE PE EDEXCEL: Long Term Effects of Exercise

Which of the following is an adaptation of the skeletal system due to exercise?

• Increased bone density

• Increased number of alveoli

• Increased size of mitochondria

• Increased elasticity of veins and arteries

What is the benefit of stronger ligaments and tendons?

• Reduced resting blood pressure

• Increased tolerance to lactic acid

• Increased strength and power

• More stable joints and less chance of dislocation or overuse injury

Which of the following is an adaptation of the respiratory system due to exercise?

• Increased tidal volume & vital capacity

• Increased myoglobin content

• Increased size of mitochondria

• Increased tolerance to lactic acid

What is the function of alveoli in the respiratory system?

• To increase bone density

• To strengthen ligaments and tendons

• To exchange oxygen and carbon dioxide

• To increase strength of intercostal muscles

Which type of muscle fibers get bigger through aerobic exercise?

• Fast twitch muscle fibers

• Slow twitch muscle fibers

• Muscle fibers with increased myoglobin content

• Muscle fibers with increased size of mitochondria

What is the benefit of increased myoglobin content in muscles?

• Increased bone density

• Increased strength and power

• More oxygen can reach the working muscles

• More carbon dioxide can be removed from the body

Which of the following is an adaptation of the cardiovascular system due to exercise?

• Increased elasticity of veins and arteries

• Increased size and strength of the heart

• Increased strength of intercostal muscles

• Increased tolerance to lactic acid

What is the benefit of hypertrophy of the fast twitch muscle fibers?

• Reduced resting blood pressure

• Increased tolerance to lactic acid

• Increased strength and power

• More stable joints and less chance of dislocation or overuse injury

What is the benefit of increased resting stroke volume?

• Increased tidal volume & vital capacity

• Reduced resting blood pressure

• More oxygen can reach the working muscles

• More carbon dioxide can be removed from the body

What is the function of capillaries in the cardiovascular system?

• To increase bone density

• To strengthen ligaments and tendons

• To exchange oxygen and carbon dioxide

• To increase strength of intercostal muscles
