Performance and Physiological Mechanism in the Aerobic Training - Case Study Example

Title Name Institution Tutor Date Client’s report We performed a V02 test to determine the maximal aerobic capacity and recorded it as in the table below. We tookthe aerobic capacity as an important parameter for determining the cardiorespiratory system functioning capacity. We measured by use of a respirometer to determine the oxygen consumed during exercise. We observed that the V02 rate increased as power increased. power V02 75 1.52 100 1.8 125 2.1 205 2.85 Estimated VO2 & Power 0.4 1.14 35 0.5 1.43 63 0.6 1.71 91 0.7 2.00 119 0.8 2.28 147 0.9 2.57 174 1 2.85 202 power 0 50 70 90 110 130 150 170 lactate 2.2 2.2 2.4 3.1 3.8 3.8 5.9 7 Abstract In our group, we carried out an aerobic training study on one of our members who was initially unfit. The aerobic training constituted of some low intensity physical exercises. In the beginning of the training, we concentrated on very light exercises and later started using moderate activities. He could not even keep up a jogging period of five minutes before the training begun. Although the training, we recorded the changes in performance. We had 3 training sessions every week for six weeks. Each session was lasting for a period of three hours without a break. Some of the aerobic exercises we embarked on running for a long distance but at a pace that was moderate, involving activities such as playing tennis and aerobic dancing classes. Other exercises were involving muscles in the body such as leg muscles, abdominal muscles and arm muscles. During the training, we recorded testing done for maximal aerobic capacity, thresholds, heart rate relationship, time to exhaustion and anthropometrics. I noticed that all these testing that were carried out had changes as the training continued. Therefore in this report I explain the changes, I observed in performance and physiological mechanism. Introduction It is not easy to note which of the physiological processes causes changes in aerobic performance. An example is the relationship that exists between metabolic responses in training and the functioning capacity of a human. In the study, we carried out during the training I noticed that any improvement in the aerobic capacity (v02) combined with metabolic control enhance the aerobic performance. The client took cycling training, which we used to monitor the progress in performance. The performance was recorded every 10 minutes in a training exercise and 10 minutes after the training. The increase in V02 shows that there was an increase in aerobic fitness (Astrand, 2001). With continued exercise, there was an improvement on the aerobic capacity which shows that our client was responding to training positively. However, with the statistics collected it is notable that the improvement in aerobic performance on the client is not at all related to capacity of oxygen transport. Muscle metabolism provides a connection between the stimulus in training and the improved performance. Metabolic parameters change in a way that they do not relate to changes in aerobic capacity. This is because the trial performances related at baseline while the v02 change did not relate to the aerobic performance (Elia, 2000). In exercise physiology, the most obtained variables is the Aerobic Capacity (vo2). In the setting of a laboratory, it is the maximum rate of oxygen that one can consume. It has implications on an individual’s health as well as exercise performance. High levels of V02 reduce chances of individual getting metabolic diseases and cardiovascular ailments. If the changes are induced through training they still relate to reducing the risks. V02 is an important determinant of change in aerobic performance. If there is an increase in V02 during training it shows that there is some training effect taking place. In our case, the client showed some gradual change in v02; therefore, it demonstrates the effect of the training we gave. V02 is commonly used to show the quantity and standards of exercise in most training studies both in performance trial and metabolic responses studies (Gabriel, 2000). The connection that exists between V02 and aerobic exercise performance is strong. Therefore, researchers need to do research on how to improve training techniques to increase the levels of V02, so that performance also increases. This is how athletes achieve different abilities with training that is relevant toV02 and positive aerobic performance. However, this can be had to achieve in the athletes who have been well trained because their V02 does not change. It is stable even though performance changes thus in such athletes the correlation does not exist. In our training, we noticed that the correlation existed since there were great improvements on aerobic performance with an increase in V02 (Gibbons, 2000). It is a surprise how no study has been developed towards determining of metabolic control in the skeletal muscle in training intensities. Therefore, it has not yet been evaluated if change in energy metabolism leads to a change in human performance. We, therefore carried out this study to training of an individual who previously had no training at all. This helps in knowing if there exists any relationship between aerobic performance and V02 and to know what determines performance of the human physiology. Methods The subject was a student who previously had no training in aerobics. He was initially unfit, and that is the reason we chose him. During the training, the body mass remained constant at 76 kg. The mean when at rest of the blood pressure was at 124/72 mmHg and the heart rate was at 70 beats per minute. Procedures The subject went through a six weeks training which was fully supervised by the group members. It took place in three sessions. Part of the training we took 30 minutes in cycling in every session. Before training started the subject had to go through four tests in cycling. At this time maximum, aerobic capacity, thresholds, heart rate/power relationship, time to exhaustion and anthropometrics were determined. The respiratory ratio of gaseous exchange always was above 1.0, and for every parameter, the maximum value was taken. Next, the subject took a 15 minutes cycling test that was submaximal. Muscle biopsies were recorded before the cycling begun, and after it ended. The heart rate was taken at the same time with respiratory gases to help in the determination of the V02. Finally, we measured the aerobic performance when the work done was at its highest level. This test was repeated 24 hours after a training session. In the days that followed the tests were subsequently added and time trials performed. This was done to be able to determine the changes that took place as a result of training. Statistical analyses All data that was collected was presented as a mean. Statistical analyses were carried out. The subject had periods when he responded highly, medium, and at times the response was very low. The differences between the means before the training begun and after the training were calculated using some sample t-tests. Also, the difference between the high training response and low response time was calculated. The linear regression was determined by the percentage change in V02 as a dependent variable and the baseline values. The correlations of Bivariate were assessed through the use of Pearson’s coefficient and significance only acceptable at p Read More
