Energy Systems and Aquathon

The human body is composed of three different energy systems that “provide energy for muscular work and exercise, including two anaerobic systems and one aerobic.” (Amezdroz, Dickens, Hosford, Stewart, and Davis,2010) (Refer to Appendix A). Our bodies need a continuous supply of energy in the form of ATP (Adenosine Phosphate) to do work. All three systems produce ATP to fuel our bodies with energy depending on the conditions of the activities, such as duration and intensity. An aquathon is “the simplest form of multisport, it consists of swimming and running” (Triathlon.org, 2018). This analytical exposition will justify how the contribution of energy from the aerobic system supports my aquathon capacities.

All three energy systems produce ATP in the form of energy. ATP is composed of the nitrogen base adenine, the pentose (5C) sugar ribose, and three phosphate groups. ATP’s primary source is carbohydrates (Refer to Appendix B). “They are obtained from foods known as complex carbohydrates.” (Amezdroz, et al, 2010) (Refer to Appendix C). When energy is required, “ATP works by losing the endmost phosphate group when instructed to do so by an enzyme.” ATP molecules can be found in all cells(Bris.ac.uk, 2018) (Refer to Appendix D). When the body is at rest there is a “low demand for ATP all energy is produced aerobically.” (Amezdroz, et al, …show more content…

Heart rate is an indicator to demonstrate the intensity and duration of exercise. The aerobic system falls under the aerobic threshold. The aerobic threshold is “the heart rate above which you gain aerobic fitness, at 60% of our MHR.” (Bbc.co.uk, 2018). Towards the end of the Aquathon the aerobic system can no longer keep with the intensity, so the anaerobic threshold begins in the last few minutes of exercise. The anaerobic threshold “is the heart rate above which you gain anaerobic fitness. You cross your anaerobic threshold at 80% of your MHR.” (Bbc.co.uk, 2018). The anaerobic systems function without the use of oxygen. “They burn through ATP and then turn to anaerobic glycolysis, using glucose and glycogen for fuel with a by-product of lactate.” (Verywell Fit, 2018). When working anaerobically it creates oxygen debt and can only continue to keep working for a few minutes. Oxygen Debt is the oxygen consumption post exercise to replenish creatine
