Question 1
The upcoming 2018 Tour De France race will be the 105th anniversary of the race and will begin on July 7, concluding on July 29. Throughout the race there will be 21 stages, where riders will have to face six mountain stages, three of six will be summit finishes, one independant time trial, one team trial and eight flat routes. All of the 21 stages total up to a staggering 3229 km, meaning preparation, training and nutritional requirements are key components if a cyclist is set on wearing the famous yellow jersey.

The Tour de France is one of the most famous cycling races in the world. Many competitors embark on a gruelling 23 day cycling race which consist of an average of 4-6 hours of intense riding daily. All riders would be using both anaerobic and aerobic energy systems throughout the race

The role of ATP-PC within the body is to provide immediate energy at any given time by breaking down the stored high energy phosphates. It is the only system that doesn’t require a blood supply and can function in the absence of oxygen. As a result, the ATP-PC system can provide a lot of energy quickly, for short bursts of time. Cyclists use this energy system when overtaking opponents or during the final sprint of the race to gain a better position. In the 2017 Tour de France, Marcel Kittel from Germany proved to be the ‘King of Sprints’ in Stage 10 of the race in Bergerac. Kittel was 500m from the finish line when he noticed his competitor, McLay started the sprint very early. Kittel seized this opportunity and began his sprint, reaching the front of the pack with 220m to go. The ATP-PC system average functional time is normally active for 10-15 seconds at most. It is free energy as the body stores ATP ready for immediate use. Once it is depleted, it can take up to 5 minutes to replenish, ready to sprint again. It is the only energy system that has no

    During strenuous exercise, such as lifting, muscles require glucose (and glycogen) as fuel faster than oxygen can be provided. Oxygen is important because it helps to do the lifting. Your muscles go into anaerobic cellular respiration because of low oxygen which causes lactate fermentation (lactide acid) to form. This is evident in the beginning of stage 2 because of the burning or aching sensation in the muscle fibres. During lactate fermentation in cells, the pyruvate which was produced during glycolysis is converted to lactide acid by oxidizing an electron…

    Introduction: Maximal oxygen uptake, or VO2 max represents the maximum amount of oxygen consumption attainable during all out aerobic exercise, most commonly running on a treadmill. The point at which oxygen consumption plateaus is the individual’s maximal oxygen uptake. If the individual does not plateau, that point is referred to as VO2 peak. VO2 max is measured in milliliters per kilogram of body weight per minute, and there are two ways to measure it, either direct or indirect. The direct method requires the subject to exercise to the extremes of their capability, and indirect methods use sub maximal exercise.…

    Cellular respiration is the process by which cells break down nutrients and produce ATP. The road through cellular respiration can somewhat vary, depending on the nutrient being processed; this article will focus on the pathway of breaking down glucose. There are three main stages of cellular respiration, Glycolysis, Citric Acid Cycle, and the Electron Transport System. For the chemical enthusiasts reading this, the chemical equation to describe cellular respiration is: C6H12O6 + 6O2 ®6CO2 + 6H2O + Energy (ATP and heat). Stage 1:…

    Ideally, a fast heart rate recovery shows that the body is functioning at the optimum level. High intensity anaerobic exercises typically cause high post-exercise oxygen uptake because the body is incapable of providing adequate oxygen during the physical activity. However, prior entering the Krebs Cycle, the insufficient activation of the pyruvate dehydrogenase complex (PDC) prevents pyruvate from converting to acetyl coenzyme A. The deficiency of PDC inhibits the Krebs Cycle and thus limits the amount of oxygen produced. The Krebs Cycle is a complex series of reactions that living organisms use to produce energy.…

    We found that cyclist Lance Armstrong was guilty of using EPO on several accounts. Erythropoietin, also know as EPO, is a drug used medically to treat anemia. This advancement in medicine has helped save lives but unfortunately professional athletes, like Armstrong, have used it to help improve their performance. The earliest claims of doping was with Gastone Nencini in the 1960 Tour De France. Around this time athletes would store blood and wait for the body to replace the loss blood.…

    For my microcycle project I was given the sport position of a baseball pitcher. Baseball pitching is an extremely explosive and sometimes an unnatural movement. The main parts of being a good pitcher is to have velocity, position, and movement. In order for there to be a successful pitch, Chris Blake of the New England Musculoskeletal Institute at the UConn Health Center says that there are 6 phases the body must go through. Phase 1 is the wind-up.…

    In one study, three males and two female thoroughbred racehorses were tested and compared to four males and one female riding horses. The racehorses averaged the age of five and the regular riding horses averaged the age of thirteen. The researchers examined the plasma malate, M/L ratio, and lactate dehydrogenase activities to figure out the energy metabolism in the horses. Plasma malate is incorporated in the ATP and NADH generation, but lactate dehydrogenase can convert NADH to NAD+ for the making of ATP. The increase of plasma M/L ratio can show a heightened metabolism energy in the skeletal muscle and liver of the horse when adapted to continuous and intensive training.…

    This system will breakdown and resynthesize ADP into ATP at a faster rate to perform the Wingate in 15 seconds. The ATP-PCR system is very immediate and stores higher energy bonds than glycoysis. ATP-PCr is used for the beginning of the exercise for a high intensity activity. Being that this duration is 15 seconds, the body will need energy at a faster rate to produce ATP. Glycolysis will not be included in this particular test, due to rapid amount of energy is needed.…

    5.0 Discussion 5.1 Adenosine Triphosphate System In touch football there are three systems used throughout the duration of the game these are the ATP system (Adenosine Triphosphate), the Lactic Acid system (anaerobic glycolysis) and the final system the Aerobic system. ATP doesn’t exist in the muscles and tissues waiting to supply abundant amounts of energy (Hede, Russell and Weatherby), ATP is a chain consisting of three phosphate groups. To produce energy the phosphate chain breaks and one phosphate group is broken off to produce this energy needed for movement. In breaking the phosphate chain, energy is used to allow the production of energy as the end product (Personal training direct, 2014).…

    Introduction A common form of athletic enhancement for athletes who compete in marathons or cycling is known as blood doping. Jeanna Bryner, Managing Editor of Live Science, states it is “an illicit method of improving athletic performance by artificially boosting the blood 's ability to bring more oxygen to muscles.” Marathonist and cyclists use this method over steroids because if there is more oxygen going into their muscles, then they are able to increase their stamina and performance. This increase allows athletes to travel long distances without becoming fatigued.…

    All three energy systems “make a contribution to exercise,” but the ATP-PCr system generates about fifty percent of the energy used in soccer. Together the glycolytic and oxidative systems are evenly responsible for the remaining sixty percent of energy used. In soccer, players alternate between sprinting and walking, so it is understandable that the ATP-PCr is responsible for such a vast amount of energy. The ATP-PCr system normally lasts for “3 to 15 s”, which would allow a player to “perform short bursts of intense running” (Kenney, W., Wilmore, J., Costil, D., 2015b, p.p. 58; Clark, 2016).…

    However, it is suggested that the player should develop a high aerobic system as it can help with processing lactic acid and increases the athletes’ ability to recover quicker when participating in high intensity sessions of sprinting in a game. It’s crucial to view and establish the energy systems that are required in a soccer game in order to train the athlete in the correct way. All three energy systems will most likely be used during a game of soccer by a defender. An example where this can be seen is if the player does a 50m sprint during a soccer match, they can use 50% of the ATP/PC system and 50% of the lactic acid which signifies that energy systems can be used together, it’s…
