Aerobic Versus Anaerobic Respiration Assignment
Select one of the following: a triathlete, a football player, a gymnast, and one phase of their sport. For example, if you choose the triathlete you can choose the cycling phase of their activity, or if you choose the football player, you could choose the sprint phase of their activity, or if you choose the gymnast, you may choose the backflip phase of their activity.
- As your athlete performs the chosen activity, discuss whether rapid or slow glycolysis is the most effective means of energy transfer?
- What physiological factors contributed to your analysis (e.g. hydrogen release, lactate formation, glucose catabolism, etc.)?
- How did these factors influence your choice?
- Explain the benefits of lactate for optimal performance of the chosen activity.
Your research and claims must be supported by your course text and a minimum of two additional scholarly sources. Use proper APA formatting for in-text citations and references.
Guided Response: Review some of your classmates’ posts. Identify at least two classmates who chose a different athlete than you chose and analyze the appropriateness of the type of glycolysis they discussed. Then, explain if you agree with the benefits of lactate identified for their chosen activity. Support your reasoning for each response to your classmates with at least one scholarly source.

Aerobic Versus Anaerobic Respiration Assignment
Interval training is a method of training where one increases and decreases the intensity of his workout between aerobic and anaerobic training (KRAEMER & RATAMESS, 2004; Talanian, Galloway, Heigenhauser, Bonen, & Spriet, 2007). Interval training in Sweden, where some say it originated, is known as fartlek training (Swedish for “speed play”)(Ferraz et al., 2010). The protocol for interval training is a well-known method for improving fitness(Dunham, 2010). Technically, it is defined as high-intensity intermittent exercise. In an interval session, high-intensity periods of work are interspersed with rest intervals. The objective of this training is to improve muscle performance (speed, strength, and endurance)(Buchheit et al., 2009).
Interval training has been the basis for athletic training routines for years(Suh, Rofouei, Nahapetian, Kaiser, & Sarrafzadeh, 2009). The first forms of interval training, called “fartlek” involved alternating short, fast bursts of intensive exercise with slow, easy activity(KRAEMER et al., 2004).
Interval training works both the aerobic and the anaerobic system. During the high intensity effort, the anaerobic system uses the energy stored in the muscles (glycogen) for short bursts of activity(Wells, Selvadurai, & Tein, 2009b). Anaerobic metabolism works without oxygen. The by-product is lactic acid, which is related to the burning sensation felt in the muscles during high intensity efforts(Muscle & Production, 2009). During the high intensity interval, lactic acid builds and the athlete enters oxygen debt. During the recovery phase the heart and lungs work together to “pay back” this oxygen debt and break down the lactic acid. It is in this phase that the aerobic system is in control, using oxygen to convert stored carbohydrates into energy(Wells et al., 2009b).
Aerobic exercise and fitness can be contrasted with anaerobic exercise, of which strength training and short-distance running are the most salient examples(Delextrat & Cohen, 2008). The two types of exercise differ by the duration and intensity of muscular contractions involved, as well as by how energy is generated within the muscle. Initially during aerobic exercise, glycogen is broken down to produce glucose, which then reacts with oxygen (Krebs cycle) to produce carbon dioxide and water and releasing energy. In the absence of these carbohydrates, fat metabolism is initiated instead. The latter is a slow process, and is accompanied by a decline in performance level (Mansouri, 2009).
Aerobic exercise comprises innumerable forms. In general, it is performed at a moderate level of intensity over a relatively long period of time(Reid et al., 2010). For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity, while golf or two person team tennis, with brief bursts of activity punctuated by more frequent breaks, may not be predominantly aerobic.
The word ‘anaerobic’ literally means without oxygen. Anaerobic exercise means you’re working at such a high level of intensity, that the cardiovascular system can’t deliver oxygen to the muscles fast enough. Muscles, trained using anaerobic exercise, develop differently compared to aerobic exercise, leading to greater performance in short duration, high intensity activities, which last from mere seconds up to about 2 minutes. Any activity after about two minutes will have a large aerobic metabolic component(Scott, 2008).
