Technique Sheet Activity - Swimming Front Crawl

Extracts from this document...

Introduction

Week Week Beginning Timetable Monitoring 1 December 31st 2001 Come to a decision on two activities to examine. Swimming and Hurdles Swimming activity - Front crawl Hurdles - Technique up to and over first hurdle 2 January 7th 2002 Prepare data collection sheets for making note of the strengths and weaknesses performed 3 January 14th 2002 Observation of front crawl 4 January 21st 2002 Observation of hurdles 5 January 28th 2002 Identification of major strengths and weakness of both subjects 6 February 4th 2002 Select sport to be analysed Selected swimmer 7 February 11th 2002 Research physiological and psychological reasons as to why the performer shows these strengths and weaknesses. 8 February 18th 2002 Give an explanation using research to justify strengths and weaknesses. Choose area for further development Chosen swimmer's conditioning ability to improve on 9 February 25th 2002 Make plan to improve swimmers conditioning, subsequently improving performance. Plan to make a swimming routine that will commence twice a week and will increase in load weekly 10 March 4th 2002 Week one of training programme 11 March 11th 2002 Week two of training programme 12 March 18th 2002 Week three of training programme 13 March 25th 2002 Week four of training programme 14 April 8th 2002 Week five of training programme 15 April 15th 2002 Week six of training programme 16 April 22nd 2002 Week seven of training programme 17 April 29th 2002 Week eight of training programme 18 May 6th 2002 Conditioning retest 19 May 13th 2002 Produce an account on the intended procedure and method. Explain the desired outcome Coaching Programme A1 - Planning B1 Technique Sheet Activity - Swimming Front Crawl Using video evidence and a digital camera to record the performances, this is a description of the ideal technique in order to perform the stroke that will significantly reduce wasted energy output through less drag in the water and a cleaner execution of hand and arm entry and recovery. ...read more.

- As the swimmers method of breathing did not require a breath for the recovery of the left arm, the head should not rotate along with the body. Instead the eyes always look straight down until the swimmer decides to breathe although this swimmer clearly turned his head despite not even taking a breath. - The rolling like a log movement continued although the arm was not as straight as it should have been, the head should also have rotated with the body. - The fingers were also spread which weakened the force applied from the whole arm movement. - The hand should also have passed closer to the body although this could be put down to the flexibility of the swimmer. - It was clear that the swimmer rotated too far (more than 45 degrees) which could have affected the propulsive force applied. - The feet dropped too far below the body's depth altering the slope that should be kept, causing a resistance to the forward motion and causing problems with the rhythm of the breathing. - The feet dropping also caused problems when the left arm as it went through the recovery stage because the whole arm would be so close to the surface of the water it would be difficult for the elbow to exit first and to keep it higher than the hand throughout. The main weaknesses were the over rotation and the timing at which the sweeps were carried out in proportion to the opposite arms. On the next pages I will explain these strengths and weaknesses with the use of photographs of a swimmer who performed the movement for me. C1 + C3 Activity - 110m Hurdles Strengths Here I will list the list the strengths that were recorded on my data collection sheet when the hurdler was being recorded: - Following the start, the athlete approached the hurdle with good sprinting style, hips high. ...read more.

Conclusion

Main: 150 full, 100 full, 50 full at 1,500m pace with 10 seconds rest intervals (300m) Warm-down: easy swim to complete the session Week 7 - 1000m Warm-up: Set C (300m) Strokes: 25 front-scull, 25 full, 25 back-scull, 50 full, 25 full-scull, 25 full (30 seconds rest) 25 ripple, 25m full, 25 fist, 50 full, 25 ripple, 25 full (350m) Main: 25 full, 50 pull, 100 full, 50 pull, 25 full at 1,500m pace with 10 seconds rest intervals (250m) Warm-down: easy swim to complete the session Week 8 - 1,050m Warm-up: Set D (300m) Strokes: 25 alternate 1-arm, 25 full, 25 catch-up, 50 full, 25 ripple, 50 full (200m) Main: 500m timed swim Warm-down: easy swim to complete the session Each session should be performed to the best of the swimmers ability throughout each session. A recovery period of a couple of minutes will be allowed between the warm-up, the variations of strokes and the main part of the session. After the eight week period has commenced, the swimmer will be re-tested in the same way that he was tested previously to measure the improvements made. E3 The interval training routine I have devised would without doubt bring about an outcome which would assist the process of becoming a more efficient and effective swimmer in the front crawl. Here are some of the physiological benefits that occur: * Maintains, tones, and strengthens the muscles as well as increasing the muscular endurance needed for swimming. * Decreases your blood pressure. * Increases the oxidation (breakdown and use) of fat. * Increased aerobic capacity (fitness level), giving the ability to go through the front crawl movement with less relative energy expenditure. * Increases HDL cholesterol. * Increases the thickness of cartilage in joints which has a protective effect on the joints. * Makes the heart a more efficient pump by increasing stroke volume. * Increases haemoglobin concentration in blood. * Increases the strength of the bones. * Enlarges the arteries that supply blood to the heart. * Decreases blood levels of triglycerides. ...read more.
