Factors Affecting The Beep Test Essay

1982 words - 8 pages

In this report, I will be writing about the data that was collected from the beep test, which tests the aerobic endurance of the participants who are performing the test. With the results collected I will be discussing the different factors that may have impacted on the participant’s results. Robinson (2010) states that there are different systems in the body such as the skeletal, muscular, circulatory, and respiratory. Despite the fact all these systems are separate, they are all linked together to help the functioning of the body when at rest and during exercise. When the body begins to participate in exercise, during physical activity changes start to occur in the cardiovascular system starts so that it can adapt to the physical activity, this links into Kenney et al, (2012) where they indicate that cardiovascular changes occur when the body starts to move during exercise, and that the main reason for this is so that the blood flow increases to the working muscles. Furthermore, there are other adjustments in the cardiovascular system, where the ‘blood flow patterns change significantly in the change from rest to exercise. Through the vasoconstrictor action of the sympathetic nervous system on local arterioles, blood flow is redirected away from areas where elevated flow is not essential to those areas that are active during exercise, only 15% to 20% of the resting cardiac output goes to muscle, but during high-intensity exercise, the muscles may receive 80% to 85% of the cardiac output.’ (Kenney et al, 2012:190)
I will also be writing how nutrition would be a key part for the participants performing the beep test as it affects the energy systems that are needed to work correctly. The energy system is what allows the participants to perform any form of physical activity. According to Fink et al, (2009) carbohydrates, fats, and proteins are known to be the body’s main source for energy. The energy that gets released is conserved to make another high-energy chemical called adenosine triphosphate (ATP); without a supply of ATP, muscles would not be able to generate force and therefore resulting athletes not being able to perform any physical activity. Furthermore, Shepard (2006 cited in Robinson 2010) has stated that the supply of ATP will only last for a limited amount of seconds, and there is a requirement to recapture ATP quickly, which is attained by the breakdown of creatine phosphate (CrP). For this physical activity, the main energy system would be the aerobic system, as it has an unlimited ability to make ATP and is the energy system most relied upon for longer-duration activities that can be performed for minutes to hours (Wilmore & Costill, 1994).
Kenney et al, (2012) indicates that with the help of oxygen it helps the body break down subtracts with to generate cellular respiration. Muscles need a steady supply of energy to continuously produce the force needed during long-term activity. The aerobic system has a larger...
