What’s In Class This Week?

With just a few weeks left in this quarter, we have wrapped up exercise physiology. Over the past 2 weeks, we have been exploring the cardiovascular system’s functions and anatomy. This week we focused on how it works.

Energy Systems

One of the major components of exercise science is understanding how the various energy systems provide fuel to our body. When our muscles are active during exercise, ATP (adenosine triphosphate) is broken down to provide the energy to allow our muscles to contract. While there is some ATP readily available, demands of exercise often require additional ATP to be produced.

ATP can be produced through the ATP-Phosphocreatine system which provides short but instantaneous bursts of energy. Following this system comes anaerobic glycolysis. This particular energy system generates ATP by breaking down stored glycogen. The anaerobic glycolysis system can also produce immense amounts of ATP nearly instantaneously, but eventually burns out and leaves muscles aching. Finally, the aerobic pathways kick into gear by using oxygen and other nutrient substrates to provide a slower, but steadier, production of ATP.

Understanding how the energy systems function is critical to a personal trainer or coach’s role in creating workouts. Clients seeking improvement in their athletic conditioning need to be pushed to their thresholds, but safely and efficiently. With proper knowledge of the various energy systems, a coach can prescribe workout routines that aim to improve one or more of the energy systems.

Next Week’s Classes

In the upcoming week, we will finish the quarter with a lesson on Neuromotor and Biomechanical principles.
