Effects of exercise on the body

Lactic acid is produced is a short term effect of which system

• cardiovascular system

• respiratory system

• muscular system

• skeletal system

Does muscle temperature increase or decrease when we exercise?

(a)  

What does the term vascular shunt mean

• The redistribution of blood to the working muscles

• The redistribution of blood to the resting muscles

• The redistribution of blood to the vital organs

• Taking blood away from the working muscles

Which of the following are short term effects of exercise on the cardiovascular system (tick all that are correct)

• Heart rate increases

• Stroke volume increases

• Cardiac output increases

• Heart hypertrophy occurs

What is the equation to work out cardiac output

• Cardiac output = tidal volume x stroke volume

• Cardiac output = heart rate x stroke volume

• Cardiac output = minute ventilation x heart rate

• Cardiac output = breathing rate x tidal volume

What are the three short term effects of exercise on the respiratory system

• Respiratory rate decreases

  Respiratory rate increase

  Cardiac output increases

• Respiratory rate decreases

  Minute ventilation decreases

  Tidal volume decreases

• Respiratory rate increases

  Minute ventilation increases

  Tidal volume increases

• Respiratory rate increases

  Stroke volume increase

  Cardiac output increases

What is the definition for minute ventilation

• The volume of air inspired

• The volume of air inspired or expired in one minute

• The volume of air inspired or expired in one breath

• The volume of air inspired or expired in per second

What is the definition of tidal volume

• The volume of air inspired

• the volume of air either inspired or expired during three breaths

• the volume of air either inspired or expired during one breath

• The volume of air expired

What are the short term effects of exercise on the skeletal system

• Increase in the number of bones in the body

• Bone density increases

• None

• Bone hypertrophy

Which four are the long term effects of exercise on the muscular system

• Muscle hypertrophy occurs

  Muscular strength increases

  Muscular endurance increases

  Resistance to fatigue increases

• Muscular endurance decreases

  Muscular strength decreases

• Muscle hypertrophy does not occurs

  Muscular strength increases

  Muscular endurance decreases

  Resistance to fatigue decreases

• No effects at all
