The Relationship Between Peak Power and Fatigue Index for Endurance vs Power Athletes.

ABSTRACT
The Wingate Anaerobic Test is used to evaluate anaerobic cycling performance. This study was undertaken to determine whether there is a relationship between peak power and fatigue index for endurance (n=9) vs power (n=4) athletes. A total of 13 subjects, including 8 males and 5 females, were included in the study. The subjects were divided into sporting types, such as endurance and power. Data collected from the Wingate test included peak power (W), mean power (W), time to peak (S), minimum power (W) and fatigue index (%). When the peak power and fatigue index were considered together for endurance athletes, a significant relationship existed, but when peak power and fatigue index were considered together for power athletes, no significant correlation existed. As a result, this study indicated that peak power and fatigue index had a significant relationship in endurance athletes but there was no significant relationship in power athletes.

INTRODUCTION
The Wingate Test is a maximal intensity cycle ergometer test lasting 30 seconds. It serves to evaluate anaerobic performance (Ayalon et al. 1974). It is commonly used and is a practical and handy method for measuring the muscle metabolism and anaerobic power (Francis, K. 1987). It measures three indices, peak power, mean power and fatigue index. Peak power is the highest mechanical power elicited from the test taken as the average power over any 5 seconds. Fatigue index is the amount of the decline in power during the test expressed as a percentage of peak power (Inbar et al. 1996). The ability to evaluate these measurements makes the Wingate test a valuable test for coaches, athletes and research scientists (Jordan et al. 2004). There has been an increased interest in anaerobic power production in sports due to the realisation that competitive athletic events largely depend on anaerobic power (Bulbulian et al.

    Maximal oxygen consumption (VO₂max) is an excellent indicator of a person’s physical fitness level. It can also be used for many other things including diagnostic tools for physicians. In this study, two different methods of collecting maximal oxygen uptake scores were compared. The first being the predicted VO₂max score attained via the Rockport test and the second being indirect calorimetry VO₂max score attained through cycle ergometer and an attached metabolic cart. Ten males and nine females of similar ages participated in both the Rockport and Indirect Calorimetry tests. It was found that the Rockport predicted tests significantly overestimated the VO₂max scores for males by 14% and females by 16% possibly due to the variability the test is subjected to. The Indirect Calorimetry was therefore deemed the more accurate test. It was also discovered that there were significant individual differences in the data due to many differing factors, including sex, body composition, heredity and physical prowess.…

    You may list, as students report out, the physiological changes to the respiratory, cardiovascular, neuromuscular, and urinary systems expected during strenuous exercise and as noted in the case of the cyclist, Joe. Students will respond with answers suggesting increases in heart rate, respiration, sweating and muscle fatigue, as well as muscle soreness as normal. However, in reality, in an effort to sustain maximum energy output over extended periods of time, endurance athletes train so that organ systems make the necessary physiological adaptations and are not subject to radical changes in function. Metabolic changes can occur with extensive endurance training in the muscles, hearts and lungs of the athlete, increasing efficiency of system utilization (Thompson, 2000).…

    Once the Creatine Phosphate stores have worn out, the body resorts to stored glucose for ATP. The breakdown of glucose or glycogen in anaerobic conditions results in the production of lactic acid. The build up of ions is the restrictive issue causing fatigue in runs of 300m – 800m. The lactic acid system is most affective around 30seconds to 2-3 mins. In touch football the use of the lactic acid system may be used when wrucking the ball, as it is a constant sprint with little or no rest.…

    Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner, their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon, the athlete is capable of using a combination of both anaerobic and aerobic pathways, but these different systems predominate at different intervals in order to increase the energy allowed for the muscles.…

    In this experiment, several physiological parameters were observed in three patients before, during, and after moderate exercise. One of these parameters was the pulmonary airflow, which was recorded utilizing an Airflow Transducer. This device measures airflow using slight pressure differences created by the resistance of a screen inside the device. Pulmonary airflow is the rate of movement into and out of the lungs, and is directly proportional to the pressure difference of the intrapulmonary pressure and the atmospheric pressure, and inversely proportional to the resistance of the lungs (elasticity/diameter of air pathways).1 The BIOPAC program then can convert the airflow to volume of air moved. Pulmonary ventilation is the movement of air in and out of the lungs. A more specific measurement of pulmonary airflow is the minute respiratory volume, which measures how much air is moved into and out of the lungs in one minute (tidal volume*breaths per minute).2 Since both deal with a volume moved per time, they are synonymous, although the parameter is referred to as airflow in this report.15E…

    VO2 Max

    In this lab it was studied what differences were present in VO2 Max according to the many variables for females and males. VO2 max is defined by the maximum amount of oxygen utilized during extreme exercise. It is known as the best indicator to the efficiency of athletes or persons cardiovascular capabilities during fitness. It is important to know the general VO2 max of an athlete because, philosophically of course, the more oxygen used during exercise, the more ATP that is produced. This translates into; the more oxygen that can be absorbed by the body, the more energy that is produced through cellular respiration, and in turn, an athlete would heighten the intensity of the workout for a longer period of time becoming a better athlete. The VO2 Max of a person can be affected by mass, time it took to walk necessary distance, and heart rate. Each variable is in turn varied be age and gender. The greater the value for VO2 Max the greater the efficiency of the cardiovascular system. VO2 max plays a major role in the aerobic energy system because an increased VO2 max permits more oxygen to the lungs which increases the amount of mitochondria available. On the mitochondria matrix is where 32 of the 36 ATP molecules are made and stored. This means that after 30 second of strenuous exercise, the aerobic system becomes the primary source of energy for the body and with VO2 max supplying the most energy, it permits the body to continue. All data that was collected was from people within the same age group, so it was decided that age would be removed from the results. Results were compared between men and females because of the different biological differences that can cause large variances in VO2 Max as variables increase or decrease. All data was acquired from classmates whom gathered personal data and released it for the use of this lab.…

    Touch & the Energy Systems

    The human body operate on three energy systems: Phosphate Energy System, (ATP/CP or CP SPLITTING), Lactic Acid Energy System (Anaerobic Glycolysis) and Aerobic Energy System (Oxygen System). ATP is when an enzyme splits one of the three phosphate molecules from Adenosine Triphosphate and this releases large amounts of energy that the muscle fibres use to create movement, this turns ATP into Adenosine di-phosphate (ADP), However, only a small amount of ATP is stored within the muscles cells, about 10-15 seconds and takes 2-3 minutes to fully replenish. When ATP is depleted the body turn to anaerobic Glycolysis for energy. This process breaks down glycogen and glucose (Sugar and Fat) to produce energy. This process creates a by-product called ‘pyruvic acid’ which converts into lactic acid if there is insufficient oxygen circulating in the muscles. If Lactic acid accumulates, the process of anaerobic glycolysis slows down, resulting in fatigue. This energy system takes 20-60 minutes depending on the fitness level to remove the accumulated lactic acid after maximal exercise. The third energy system is a much slower process of collecting energy, however; the energy produced lasts longer than the other two energy systems, and therefore it is…
