During a 200- to 400-meter run, the dominant energy system is the anaerobic glycolysis system. This system provides energy for high-intensity efforts lasting from about 30 seconds to 2 minutes, relying on the breakdown of glucose without oxygen. As the distance increases, the reliance on aerobic metabolism also begins to play a role, but for this middle-distance range, anaerobic energy production is key.
The dominant energy system during exercise is determined by the duration and intensity of the activity. For short, high-intensity efforts (like sprinting), the body predominantly relies on the ATP-PC system and anaerobic glycolysis. In contrast, longer, moderate-intensity activities (such as distance running) primarily utilize aerobic metabolism. Additionally, factors like fitness level and the availability of oxygen also influence which energy system is most active.

During recovery, the body primarily relies on the aerobic energy system. This system utilizes oxygen to convert carbohydrates and fats into ATP, the energy currency for cellular processes. The aerobic system becomes dominant as the body aims to replenish energy stores, clear metabolic byproducts like lactate, and restore homeostasis following physical activity. Adequate rest and nutrition further support this recovery process.
The aerobic system is the dominant energy system for the whole beep test. This is because the intensity is sub-maximal and the duration is longer than 90 seconds. As the athletes glycogen stores depletes the anaerobic glycolysis system increase its contribution to the synthesis of ATP. The ATP-PC system is making minimal contribution for the whole duration of the beep test.
The primary energy system used during the bench press is the phosphagen system, also known as the ATP-PCr system. This system provides immediate energy for short-duration, high-intensity activities, typically lasting up to 10 seconds. As the sets continue or the duration increases, the body may also begin to utilize anaerobic glycolysis, which generates energy for up to 2 minutes of sustained effort. However, for maximal lifts, the phosphagen system is the dominant source of energy.
Depending on how intense the game and competitor, all energy systems are used in basketball (ATP - PC, Lactic Acid and Oxygen systems). The Oxygen system would probably dominate in a slower, more controlled game of basketball (possibly NBA) but the ATP-PC system (with some assistance from the Lactic Acid system) would probably dominate in a faster, more aggressive game (NCAA or college ball) where the players would need to recover either by playing predominantly either offense or defense (but not both) and / or subbing off and on the court during the game.
During exercise, the body utilizes three main energy systems: the phosphagen system, glycolytic system, and oxidative system. The phosphagen system provides immediate energy for short, high-intensity activities, while the glycolytic system supports moderate-intensity efforts lasting from about 30 seconds to 2 minutes. The oxidative system becomes dominant during prolonged, lower-intensity activities, such as aerobic exercise. Regardless of the type of exercise, all three systems work together to supply the energy needed for performance, with contributions varying based on intensity and duration.
The autonomic nervous system is dominant during sexual arousal, specifically the parasympathetic division. This division promotes relaxation, blood flow to the genital area, and increased sensitivity, which are all important for facilitating sexual response.

The anaerobic energy system is the primary source of energy during a 200-meter run. This system relies on stored energy in the muscles and does not require oxygen for energy production. It provides a quick burst of energy for short bursts of intense activity like sprints.
The dominant parasympathetic system refers to the state in which the parasympathetic branch of the autonomic nervous system is more active than the sympathetic branch. This system is primarily responsible for promoting "rest and digest" functions, which include slowing the heart rate, enhancing digestion, and conserving energy. When the parasympathetic system is dominant, the body is in a relaxed state, allowing for recovery and maintenance of bodily functions. This state contrasts with the sympathetic system, which prepares the body for "fight or flight" responses.
