Introduction

Stage 2 Physical Education "Exercise Physiology Laboratory Tests" By Olivia Roberts 1201 1. Results: Test My Score My Rating Boys Average Girls Average Class Average Standing Long Jump 1.9 m Very Good 2.23 m 1.745 m 2.038 m 40m Sprint 6.7 sec Below Average 5.65 sec 6.598 sec 6.06 Sit Ups 61 Excellent 54.61 42.8 49.9 Sit and Reach 33 cm Excellent 22.44 cm 29.75 cm 25.36 400m Sprint - - 115 sec 152 sec 128 sec Grip Strength 40 kg Excellent 55.78 kg 36.17 kg 47.93 kg 20m Shuttle Run Level 6 Shuttle 1 Good Level 9 Shuttle 8 Level 6 Shuttle 2 Level 8 Shuttle 2 Although my 40m sprint and 20m shuttle run results were below average, my other results were much more positive. I am above average for girls in standing long jump, sit-ups, sit and reach and grip strength. I was unable to participate in the 400m sprint because of illness. Considering these factors, I would consider my present state of fitness moderately high. 2. Standing Long Jump 1. What are the main muscles being tested? The muscles being tested would predominately be the legs muscles. In particular, the quadriceps and calf muscle groups. 2. Name 2 actions from a sport that this test would be highly specific to 2 actions in a sport that this exercise relates to are: * Long Jump or Triple Jump, as the athlete jumps as far as he/she can from a specific point * High Jump, the same muscles are used to push off the ground at the start of a jump. ...read more.

For the rest of the run, the anaerobic glycolysis system will be most predominant. However, if the run outgoes 1 minute the aerobic system may take control. 2. Describe your feelings at the end of the run (muscles, breathing, etc) and explain in physiology terms why you felt this way. Use the terms O2 debt (alactacid and lactacid), stroke volume, heart rate etc. I didn't participate in this event, although I believe it would make the body feel tired and exhausted. Fatigue in muscles is due to a build up of lactic acid during anaerobic glycolysis. During the race tidal volume, heart rate, stroke volume and cardiac out put would have increased due to the extreme intensity and duration of the exercise. When finished, all four measures would slowly decrease to normal levels. 3.Why does light exercise (eg walking around or slow jogging) after this run, make u recover quicker? After the run, you should walk or slow jog to help your body recover quicker to increase the levels of oxygen and blood circulation in your body. This helps get rid of lactic acid build up in the muscles. 7. Muscular Strength 1. What muscle group was tested? This tested the strength of our handgrip. It therefore was using the flexors and extensors of the wrist and fingers. 2. Why are isometric strength machines able to produce greater gains in muscular strength? The isometric strength machine is easy to perform and reliable in providing an index of muscular strength because it has a reasonably high correlation with total body strength. ...read more.

Conclusion

2. 20 Metre Shuttle Run To improve aerobic power needs continuos training. Most highly trained athletes of aerobic power have a minimum of three sessions per week. Training to improve aerobic power may include: * Keeping the heart rate in the 'training zone' for at least 20 minutes for each session * Participating in sports that offer the best aerobic activity, such as swimming, running and cycling * Joining a local fitness centre that offers various forms of aerobic training such as aerobic classes, boxercise, spinning classes and pump circuits. b) What would the effects of a long term cardiac vascular training program have on heart rate etc. (Chronic effects of training) Sustained aerobic training results in the enlargement of the heart muscle itself. In endurance athletes, an increase in the size and volume of the ventricles of the heart occurs. This in turn significantly increases stroke volume. Long-term training also leads to an increase in the blood and oxygen supply of the heart muscle. This allows it to beat more strongly and efficiently during exercise and rest. Thus, giving the athlete a lower heart rate. 10. It is dangerous to make an assessment of a person's ability in any test on the basis of one performance. Suggest 8 possible reasons why an individual might under-achieve in any of all of these tests on a particular day. They might under achieve because of: 1. Illness 2. Injury 3. Lack of motivation 4. Lack of stretching which results in poor performance 5. Low energy, from lack of food or sleep 6. Lack of concentration 7. Lack of arousal 8. Lack of alertness ...read more.
