Hypothesis: Even though the 1.5 mile run test will not produce the highest average VO2 max, the results of the 1.5 mile run will produce the most accurate VO2 max results as the test puts the most physiological demand on the body compared to the Queens College/McArdle Step Test and the Rockport One Mile Walk Test.
Discussion:
The Queens College/McArdle Step Test, the Rockport One Mile Walk Test, and the 1.5 Mile Run Test are three different field tests that were performed in this lab that were used to measure and predict an individual’s aerobic capacity. The measurement of aerobic capacity, or VO2 max, is a valid way to assess an individual’s cardiorespiratory fitness level. VO2 max refers to the maximal amount of oxygen an individual utilizes during intensive exercise. A higher VO2 max demonstrates a more efficient cardiorespiratory system as an individual with a higher VO2 max can sustain a higher intensity for a longer

Overall, the data collected from this lab supported the hypothesis that even though the 1.5 mile run test will not produce the highest average VO2 max, the results of the 1.5 mile run will produce the most accurate VO2 max results as the test puts more physiological demand on the body compared to the Queens College/McArdle Step Test and the Rockport One Mile Walk Test. Even though theoretically all three of the field tests should have produced the same estimate of aerobic capacity, the three tests produced different results due to various reasons. Since the 1.5 mile run placed the most physiological demands on the body, this test was a better indicator of individual VO2 max. Overall, all three of the field tests proved that males had a higher average VO2 max compared to women. In addition, individuals who are aerobically trained tend to perform better considering these individuals are able to sustain a higher intensity level for a longer amount of
Submaximal and maximal exercise testing are two analytic methods that can be used to examine the cardiovascular, and cardiorespiratory fitness/health levels of the individual being examined. Submaximal testing is usually preferred over maximal mainly because the submaximal exam is more practical in a fitness/health environment. Both test require the individual being examined to perform controlled exercise on a(n) treadmill/ergometer until either steady state has consecutively been reached (submax), or the individual reaches their max (close to it). Being that both test are set to exceed time limits of more than 3 minutes we examine the use of the ATP-PC, Glycolytic, and Oxidative energy systems. Although a huge portion of the test involves the use of the oxidative energy system, we must remember that the three systems are co-occurrent.
In a similar study, researchers determined VO2 max using four different methods of treadmill running, cycle ergometer, step test and prediction2. The results found that the treadmill had the highest VO2 max followed by the ergometer, and the step test and prediction were the lowest2. This supports the findings of our experiment, showing that VO2 max will be higher2 depending the tests mode of exercise and how trained the subject is in that exercise.
The higher a person’s VO2max, the longer they can sustain endurance events at higher training intensities. Conclusively, the experiment proved that the trained participant had a higher VO2max (higher oxygen consumption) and was indeed more fit than that of the untrained participant.
Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold. (Simon and Levisohm 1987). Cardiovascular fitness helps to improve a healthy lifestyle.

VO2 max is defined as the maximum volume of oxygen that can be consumed per minute as a measure of fitness (Marlin). To accurately measure VO2 max a maximal amount of physical effort will be needed to fully tax the aerobic energy system. Exercise intensity will be increased while measuring ventilation and oxygen and carbon dioxide concentration of the the inhaled and exhaled air. VO2 max is achieved when oxygen consumption remains at steady state despite an increase in work intensity. Those who are deemed fit will have a higher VO2 max. Proper exercise and training can influence your VO2 max while age can cause your vo2 max to decrease. The mean value of VO2 max for male athletes is estimated at 3.5 litres/ minute and for a female athlete is about 2.7 litres/minute these number are referred to as the absolute value. Physical limitations and physiological factors will affect the Vo2 max testing. Using the modified Bruce protocol and analysis the results, Dr. Burt Staniar and Abby Hughes determined their respective VO2 maxes. VO2 max is reported
Interval training brings many benefits to the aerobic system. Perhaps the most important benefit is an increase in its capacity to produce energy. This is brought about by increased capacity to consume oxygen during exercise. Several experiments have yielded results demonstrating that interval training increases both VO2 peak (Perry, 2008) and VO2 max (Sloth, 2013). Oxygen is necessary for the conversion of sugar, protein, and lipids into usable energy. The chemical processes involved in aerobic metabolism are not possible without oxygen, particularly the electron transport chain, the mechanism responsible for 95% of the ATP needed to keep cells alive. Oxygen is necessary to capture the large amount of energy locked in the chemical bonds of pyruvic acid, the product of the anaerobic process glycolysis. Thus, the more oxygen the body is able to consume, the greater production of ATP via the aerobic system.
Run Lola Run is a German film created in 1999. The film is set in Germany, or more specifically Berlin and follows Lola, and her difficulty in collecting up 100,000 marks to save her boyfriend from Ronnie (Manni’s boss). The film reruns the same story three times, each course highly influenced by a small change of time. Each ‘run’, affects almost everything, including the characters that appear
There are many tools to assess functional exercise capacity most of which provide good information about body system. The most popular clinical exercise tests are stair climbing, a 6MWT, a shuttle-walk test, detection of exercise-induced asthma, a cardiac stress test and a cardiopulmonary exercise test) (ATS, 2002). In the past, the functional exercise capacity was assessed by asking patients “How many flights of stairs can you climb or how many blocks can you walk?”; but, this assessment was a subjective measurement. In addition, the first objective tool was in 1960s which was 12 minute walking test; however, it was so exhausting for patients. As a result from that, a 6 minute walking test (6MWT) was found to be used as an objective measurement tool for functional exercise capacity in patients with mild or moderate respiratory diseases and cardiac diseases (ATS, 2002). Many studies have concluded that 6MWT is inexpensive test and“… it is easy to administer, better tolerated, and more reflective of activities of daily living than the other walk tests” (ATS, 2002). Therefore, this essay will describe the 6MWT and comment on administration, application, reliability and validity based on the literature reviews.

After that, the subjects were ready to begin testing. During the first eight visits, the participants performed the exhaustion ride (ER) at the same time of day. Most of the ERs were performed on a week by week premise, but sometimes it went up to 3 weeks in between test sessions. The first phase of the ER involved 5 min of non-stop cycling at around 50% VO2max with a pedal frequency that was between 60 and 100 rev/min. During the second phase, subjects rode until they felt exhausted at roughly 80% VO2max at the same pedaling frequency. Once the pedal frequency fell below 50 revs/min they had to stop. The data revealed that supplements of caffeine remarkably increased total exercise time, even if the caffeine in capsule form was taken right

Cardiorespiratory endurance: This includes the ability to sustain cardiorespiratory exercise such as running or riding a bike for an extended amount of time. This makes your heart, blood, lungs work together to provide enough energy, oxygen, and nutrients, to the working muscles to avoid fatigue.
Endurance running is a rewarding experience that puts to test an athlete’s courage, perseverance and determination. It is a marvelous wonder how the human body, with the proper conditioning and mental focus, could achieve such tasking running distance. Elite runners complete the marathon course in just over 2 hours, while the average runner completes it in about 4.5 hours. It’s difficult to comprehend how someone could run, consistently, for 4.5 hours.The actual marathon is simply a formality as the journey starts the day training begins. The outcome, the day of the marathon, is dependent on how successful the training program was executed. Long distance runners are the biggest advocates of the sport, always convincing others to jump on the training wagon. However, some runners, while they refuse to admit it, ponder if the effects of long distance running could be doing more damage than good. It is true that long distance running is potentially dangerous to the heart; however, research suggests that physician examination, as well as proper mechanics and posture during the training phase would ensure an enjoyable journey towards reaching an endurance goal injury free and would even benefit the heart in the long run.
Aerobic exercise involves improving the cardiovascular system. It increases the efficiency with which the body is able to utilize oxygen (Dintiman, Stone, Pennington, & Davis, 1984). In other words, aerobic exercise means that continuous and large amounts of oxygen are needed to get in order to generate the amount of energy needed to complete the workout. The most common type of aerobic exercise is long-distance running, or jogging. While running, the body requires large amounts of energy in order for the body to sustain energy. “During prolonged exercise, most of the energy is aerobic, derived from the oxidation of carbohydrates and fats” (Getchell, 1976).
