Tour De France Energy Systems Analysis

857 Words4 Pages

When a professional cyclist is competing in the Tour de France, they tap into all three of their energy systems while they are participating in the event. The three energy systems consist of the alactacid system, the lactic acid system (both of these two systems are anaerobic- meaning they do not require the intake of oxygen for the individual to be able to release energy) and the aerobic system (where body needs oxygen to supply it to the working muscles in order to sustain readily body movements). The three energy systems work in conjunction with each other, where the athletes differing intensity will determine the system in which they are using to maximise their performance to increase their chances of winning. The different systems used …show more content…

This particular system only last for a short period of time, that is, when the rider is exerting their maximal intensity levels at a specific time during the race, they tap into this system in order to obtain the short burst of energy their body needs. This explains why the duration of this particular system is very short, as the athlete’s short burst of energy only last for a minimal time as their ATP stores are accumulated by their muscles at a faster rate than which it is being produced. Muscles needing this quick burst of energy could be due to the athlete’s sharp change in intensity. This allows us to see why the Alactacid system’s duration last for only for 10-12 seconds, where the rider is at a current state of maximum intensity (95-100%). This particular system has no by-products, but your body does let off a certain amount of heat (like every other system in your body). When it comes to the race, this system plays a pivotal role in allowing the athlete to exert a short burst of energy which will allow them to take over other riders during the tour de France. The rider will tap into this system when they plan on riding at a high intensity for a specific purpose. During the actual race itself, the rider would tap into this system multiple times throughout the race when at a higher intensity than per usual. For example, a rider would rely on this system when they are sprinting to the finish line or they plan (tactically) to sprint away from the leading pack

Facilitated Diffusion Case Study

Also during exercise the amount of glucose produced by cells increases due the requirement for more ATP from working muscles, than from those at rest. The influx of glucose to the bloodstream after consuming a meal or snack shows how the components of the glucose homeostasis system work together to re-establish normal blood glucose concentration. The rainbow rage is a long and tiresome race, therefore, blood glucose levels may run low due to their depletion.

The Dangerous Delusions Of Energy Independence Analysis

375 Words | 2 Pages

In Robert Bryce’s article “The Dangerous Delusions of Energy Independence” he explains the depths of America’s delusional perception of energy independence and asserts his evident disapproval of the subject. He begins by mentioning past presidents and their verbal concerns of an upcoming energy crisis leading into the similar views held by America’s majority. The fact that energy independence will make America self-sufficient, create new jobs, keep U.S. soldiers out of the Persian Gulf, and result in a thriving economy has become a generally accepted attitude. Bryce claims that this attitude has escalated since the attacks of September 11th due to the numerous news stories proposing that “buying oil from the countries of the Persian Gulf

Cardiopulmonary System

486 Words | 2 Pages

If we imagine that an individual has begun exercising, the oxygen uptake increases because there is a higher demand for energy. Oxygen is the ultimate source of energy that allows ATP to be generated. More ATP must be made in order for homeostasis to be maintained. After a prolonged period of exercise, lactic acid accumulation begins to occur in the tissues of the body because the energy for oxygen uptake can no longer be supplied after a certain period of time of exercise. When the individual ends exercising, it takes time for the oxygen uptake to return to its resting level because the lactic acid that had accumulated in the tissues must be broken down into CO2 and H2O.

Vo2 Max Lab Report

296 Words | 2 Pages

VO2 max measure the maximum volume of oxygen consumed by the body to convert energy from the food that we eat into ATP that can be used at the cellular level of the body. VO2 max is important because it measures the ability of the body to produce ATP which enables the muscle to work during exercise. In order to generate ATP during aerobic exercise, the body requires oxygen. The VO2 max is a good indicator of an individual’s of cardiorespiratory capacity and endurance exercise is a way to significantly increase this capacity. VO2 max is important to the health of an individual because it measures the ability of the cells to extract and used oxygen.

Autonomic Nervous System Case Study

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

How To Maintain Homeostasis

1856 Words | 8 Pages

Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.

Aldosterone And Exercise

120 Words | 1 Pages

In the human body, exercise can be a source profound physiological changes. In particular, its impacts the release of fundamental hormones in the body. The adrenal glands is the body 's main site of steroid hormone release and it responds to increased physical activity through the release of hormones such as cortisol and aldosterone.(Buono & Yeager, 1991) Aldosterone is an essential hormone used by the body to maintain sodium and fluid balance. It exerts it effects by increasing sodium re-absorption and potassium secretion in the kidneys and in turn this also increases water resorption.(Garrett & Kirkendall, 2000)
