Long Term Effects of Aerobic Endurance Training

Which of the following best describes the musculoskeletal system?

• The system that includes the heart and blood vessels

• The combined body systems involving muscles and skeleton

• The system responsible for breathing and gas exchange

• The system that regulates body temperature

What is one of the key adaptations of the musculoskeletal system due to regular exercise?

• Decreased muscle mass

• Increased bone density

• Weakened ligaments

• Reduced flexibility

How does exercise lead to muscle hypertrophy?

• By causing muscle fibers to shrink

• By creating small tears in muscle fibers that heal and thicken

• By reducing the number of muscle fibers

• By increasing fat storage in muscles

Which adaptation helps a gymnast prevent fractures during training?

• Increased muscle fatigue

• Increased bone density

• Decreased flexibility

• Increased heart rate

What role do tendons play in physical activity?

• They provide energy for muscle contractions

• They connect muscles to bones and stabilize joints

• They transport oxygen to muscles

• They regulate body temperature

Which of the following is NOT a long-term effect of aerobic exercise on the cardio-respiratory system?

• Increased stroke volume

• Decreased resting heart rate

• Increased muscle mass

• Increased number of red blood cells

What is cardiac hypertrophy?

• Decrease in heart size

• Increase in the size and strength of the heart

• Reduced efficiency of blood circulation

• Decrease in heart rate during exercise

How does an increase in the number of capillaries affect athletic performance?

• It decreases oxygen delivery to muscles

• It increases the efficiency of gas exchange

• It reduces the heart's pumping capacity

• It leads to muscle fatigue

Why is it important for athletes to have a higher number of red blood cells?

• They help in muscle recovery

• They carry more oxygen to working muscles

• They reduce blood pressure

• They increase body temperature

What is the impact of stronger diaphragm and intercostal muscles on breathing?

• Decreased tidal volume

• Increased vital capacity

• Reduced oxygen intake

• Increased resting heart rate
