Movement in the Body

Increasing physical activity helps speed up your body’s absorption of insulin. While exercising, your muscles contract, they get the energy to do so from glucagon, a form of glucose. In order to really grasp the concept of exercise and commit to it, it’s important to understand the effects of exercise on the body.


  • glucagon is created from glucose to give muscles the energy to contract
  • more blood is moved to the muscles to deliver the glucagon
  • breathing increases from oxygen in the increased blood flow
  • muscles tear and heal again to get bigger and stronger


  • breathing gets faster and heavier because more oxygen is needed in the body
  • VO2 max (max capacity for oxygen use) is increased


  • heart rate increases to pump blood filled with oxygen
  • routine exercise gets the heart in a routine, and with more “practice” the heart becomes stronger and more “skilled”
  • stimulated vessel growth, which decreases blood pressure


  • increased blood flow leads to higher functioning brain cells, making you more alert and focused after exercise
  • endorphins are released, increasing your mood


  • joints are toughened and stronger from adding weight to them
  • reduces chance of arthritis
