Introduction: In sports, athletes use various types of energy pathways to perform their best and achieve their goals. These pathways are essential in providing energy for the body to carry out different functions during physical training or competition. In this answer, I will provide an example of an athlete who uses all three major energy pathways during competition and explain the individual demands that elicit their use.
Answer: An excellent example of an athlete who uses all three major energy pathways during sports competition is a 400-meter sprinter. A 400-meter sprint is a high-intensity exercise that requires the athlete’s body to produce energy for an extended period. The three major energy pathways used by the 400-meter sprinter are the phosphagen system, glycolysis, and oxidative system.
The phosphagen system is the primary energy pathway used during the first few seconds of a 400m sprint. This system provides energy through the breakdown of creatine phosphate stored in the muscles. As the athlete continues running, the body’s demand for energy increases, and the glycolytic system takes over. Glycolysis breaks down glucose to produce energy that is used to fuel muscle function, and it occurs in the cytoplasm. The glycolytic system is the primary pathway used for energy production in the 400-meter sprinter during the middle part of the competition.
As the race progresses, the oxidative system becomes the dominant pathway. It works by breaking down carbohydrates, fats, and proteins in the presence of oxygen to produce energy. It is the most efficient pathway, providing prolonged energy production that allows athletes to stay active for an extended period without fatigue.
The utilization of all three major energy pathways is necessary for the athlete to perform at their best during the competition. Without the phosphagen system for quick energy production at the start of the race, the athlete would struggle to keep up with the rest of the pack. The glycolytic system, providing energy for the middle part of the race, enables the athlete to maintain their speed. Finally, the oxidative system allows the athlete to finish the race by providing energy continually over an extended period. Therefore, the utilization of all three pathways by a 400-meter sprinter is necessary to compete at the highest level and maintain their high level of performance throughout the race.
