Introduction

1 ASSESSMENT TASK # 2: BODY IN MOTION 1. Describe the fitness test performed in the lab that effectively measures cardio-respiratory endurance. (5 marks) The fitness test performed in the lab that was used to effectively measure cardio-respiratory endurance was the multi-stage fitness test otherwise known as the 20 metre shuttle run or the 'beep' test. Two cones were set up twenty metres apart. The participant must move between the cones back and forth throughout the duration of the test. This test is based under the instruction of a voice on a CD. The CD may be purchased from The Australian Coaching Council / Australian Sports Commission and it is important that the tape or CD is not damaged in any way as this could affect timing of the beeps due to stretches on the CD or stretching of the cassette. The volume of the tape must also be loud so that all participants can hear it. Prior to the test participants are advised to stretch and warm up to reduce the risk of injury. Appropriate supportive clothing and footwear is to be worn to maximise safety. The voice instructs participants of what they are required to do throughout the entire duration of completing the test. At the beginning of the test the voiceover instructs when there are 20 seconds and 5 seconds until the commencement of the test and then participants must begin the test. They must reach the opposite cone before a sounded beep. The pace of the participant is influenced by the beeps. The beeps begin at a considerably slow speed and gradually throughout the test the frequency of the beeps increase necessitating for the participant to gradually progress from a slow jog, to a run and then to a sprint. ...read more.

Our heart rhythmically contracts requiring a rich supply of blood and oxygen to do this. The cardio-respiratory system played a vital role in order for me to complete the beep test. Prior to the test both the respiratory and circulatory systems and the co-functioning of these making up the cardiovascular system were all at rest. They were functioning as normal because no extra stress was placed upon the heart. For example; my resting heart rate was measured at 60 beats and my respiration at 16 breaths. Both my heart rate and respiration rate however was evidently affected by exercise as was both of these bodily systems. I do not think that my demand for oxygen was increased prior to the commencement of the test because I really wasn't nervous or anticipant which for other people may have led to their heart rate to increase even before the physical aspects of the test had begun. During the test my respiratory activity increased to facilitate for my demand of increased oxygen consumption. Greater volumes of air were being consumed during the test. For example; I reached level 10, shuttle 2 in the test. My breathing rate had more than doubled over the intercourse of the test. The total output by the heart known as cardiac output also increased during the test and may have reached up to 25 litres per minute. During the test, the supply of oxygen was increased so that my muscles could continue working. While the test was occurring a greater demand was placed on the heart to pump and circulate blood around the body and to the muscles quicker. ...read more.

Conclusion

My respiration rate prior to the test was 16 and immediately after the test were 36 breaths. After completing the beep test I was very out of breath and the feeling of exhaustion embodied upon me. The circulatory and respiratory systems roles as described in question 2, had to work at a much faster pace to supply oxygen to the heart and pump blood around the body and the muscles so that the too could work effectively thus why my breathes rapidly increased to try to facilitate and consume as much oxygen and replace the oxygen from the process of oxygen debt.

These results display that I am able to take up a greater amount of oxygen to my muscles than the average female in the 10-19 year old age group. My absolute VO2 max is 3.0 L/min which categorised me in the excellent range. In conclusion I have an overall excellent individual level of cardio-respiratory fitness. My results indicate that when compared to the norms for my respiration rate, heart rates and level of achievement I am well above average and in the top category for each of these. This means that my respiratory and circulatory system work efficiently and partake their roles both as independent systems and when working together. ...read more.

    In this case, the habitual posture results in a relative shortening of certain muscles and a relative lengthening of others. This is known as a functional leg length discrepancy. Again, such a biomechanical compensation because of a real or functional leg length discrepancy is not necessarily a problem.

At exhaustion, blood pH can approach 6.8. Only after exercise stops does blood pH stabilise and return to its normal pH level of 7.4.

    The parasympathetic nervous system and the sympathetic nervous system. For the heart rate to increase an impulse is sent to the sympathetic nervous system were the accelerator nerve is situated. The hormone adrenaline is then produced by the accelerator nerve and is released onto the Sinoatrial node, which is the pacemaker of the heart.
