Effects of Exercise on the Body Systems

What are the short-term effects of exercise on the cardiovascular system?

• Decreased heart rate, decreased blood flow, and decreased oxygen delivery to the muscles.

• No effect on heart rate, blood flow, or oxygen delivery to the muscles.

• Increased heart rate, decreased blood flow, and decreased oxygen delivery to the muscles.

• Increased heart rate, increased blood flow, and increased oxygen delivery to the muscles.

How does exercise affect the respiratory system in the long term?

• Exercise damages the respiratory system and reduces lung capacity.

• Exercise improves lung capacity, strengthens respiratory muscles, and improves oxygen exchange efficiency.

• Exercise weakens lung capacity, weakens respiratory muscles, and decreases oxygen exchange efficiency.

• Exercise has no effect on the respiratory system in the long term.

What are the benefits of exercise on the muscular system?

• Exercise on the muscular system can cause muscle damage.

• Exercise on the muscular system helps to increase muscle strength, improve muscle tone, enhance muscle endurance, and promote overall muscle health.

• Exercise on the muscular system can lead to muscle weakness.

• Exercise on the muscular system has no benefits.

How does exercise impact the skeletal system?

• Exercise impacts the skeletal system by increasing bone density, strengthening muscles and improving joint flexibility.

• Exercise only impacts the muscles, not the skeletal system.

• Exercise weakens the bones and joints.

• Exercise has no impact on the skeletal system.

What are the different energy systems used during exercise?

• phosphagen system, glycolytic system, aerobic system

• endocrine system, immune system, digestive system

• muscular system, cardiovascular system, nervous system

• anaerobic system, aerobic system, respiratory system

How does exercise improve cardiovascular endurance?

• Exercise improves cardiovascular endurance by increasing the risk of heart disease.

• Exercise improves cardiovascular endurance by decreasing the efficiency of oxygen delivery to the muscles.

• Exercise improves cardiovascular endurance by reducing the body's ability to use oxygen during physical activity.

• Exercise improves cardiovascular endurance by strengthening the heart muscle, increasing the efficiency of oxygen delivery to the muscles, and improving the body's ability to use oxygen during physical activity.

What happens to the respiratory rate during exercise?

• Fluctuates

• Stays the same

• Increases

• Decreases

How does exercise strengthen muscles?

• Exercise causes microscopic damage to muscle fibers, which are then repaired and strengthened.

• Exercise has no effect on muscle strength.

• Exercise reduces the number of muscle fibers.

• Exercise increases the size of muscle fibers.

What are the long-term effects of exercise on bone density?

• Exercise increases bone density and reduces the risk of osteoporosis.

• Exercise only increases bone density temporarily and does not have long-term effects.

• Exercise decreases bone density and increases the risk of osteoporosis.

• Exercise has no effect on bone density.

How do the energy systems contribute to exercise performance?

• The energy systems have no impact on exercise performance.

• The energy systems only provide energy for short bursts of exercise.

• The energy systems are responsible for muscle growth during exercise.

• The energy systems provide fuel and sustain energy levels during exercise.
