Exercise Physiology is at the core of every champion. Every one of our training courses, every performance enhancement, comes first from a solid understanding of how the body responds to exercise and stress. Athletic Republic in Santa Ana, CA would like to take this opportunity to give you a short study into the physiology of an athlete in training.

Definition of Fitness

There are five components to being fit. Muscular endurance, muscular strength, cardiovascular endurance, flexibility and body composition (fat to muscle ratio.) A good balance of these five components marks being fit to someone who is not an Olympic athlete. But athletes are specialists. They train on the aspects of fitness they most need for their sport.

How Does Your Body React During Athletic Training?

  • Muscles: This part of your body uses glucose and chemical energy for contraction and movement. Extra oxygen creates more chemical energy that starts you heart pumping which moves more blood to your muscles.
  • Lungs: While working your muscles calls for more oxygen, your breathing rate increases. Once the muscles around your lungs can't move any faster, you have reached VO2 max. This is your highest capacity of oxygen use. The higher your VO2, the fitter you are.
  • Heart: To supply oxygenated blood to your muscles, your heart rate increases with physical activity. The fitter you are, the better your heart can do this which will allow you to workout for a longer amount of time and harder. As new blood vessels form, your resting blood pressure will be lower.
  • Brain: Increased blood flow benefits your brain. As a result, you will tend to feel more focused after a workout. Exercising on a regular basis will promote the growth of new brain cells which will help boost memory and learning. Your brain also needs water. Keeping hydrated during workouts is very important.
