Has maintained at the top of his sport ever since, currently winning Gold in both the K1500m, K15000 and K21000 at the World Cup in Europe.Wallace’s AttributesA well trained athlete, whose heart is very efficient, beating 42 bpm at rest, with the ability to beat up to 200bpm during competition. Ken is 188cm tall, and weighs 89kg.His VO2 max is extremely high (75 mls/kg/min)Low Body fat = 4% to 5%, therefore high lean muscle massHigh Lactate threshold, therefore low lactic acid levels during intense competition and trainingHigh muscle efficiency enabling him to harness more power52984406223000In the space below write down the impact of these adaptations on Wallace’s performance.Stroke Volume and Cardiac Output (Slide 7)Activity 5:Show your understanding of the graphs below by writing your interpretation in the space provided.431808699500349258445500Fox, E, Bowers RW & Foss, M, The Physiological Basis of Physical Education and Athletics, 4th Ed., Wm C Brown Publishers, DubuqueOxygen Uptake (Slide 8)Activity 6:Show your understanding of the graph by writing your interpretation.420878013081000How can Nutrition Affect PerformanceThe Overcompensation Model (Slide 9)Activity 7:Ruskin, R, Proctor, K., &Neeves, D., Outcomes 2 HSC Course: Personal development, Health and Physical Education, 3rded.Wiley, Brisbane, 2007In the space below write down your interpretation of this diagram. (HINT – Role of Recover)Recovery Strategies (Slides 10, 11, 12)Activity 8:Match the type of recovery strategy with the description. Then identify whether the strategy is Physiological (Ph), Neural (N), Tissue Damage (TD) or Psychological (Ps). StrategyNo.Type1.2.3.4.5.6.7.Decreases skin, subcutaneous and muscle temperature, causing narrowing of the blood vessels (vasoconstriction), which dulls and reduces the sensation of pain, limiting the amount of swelling, reducing muscle spasm and clearing metabolites from superficial skin tissue.Gradually reduces heart rate and metabolism to pre-exercise state. Ventilation rate, blood distribution, adrenalin levels are gradually reduced.Involves a range of different techniques including progressive muscular relaxation, flotation, meditation visualization etc. Choice of technique is very individual.Replenishment of depleted glycogen and blood sugar in the first 30 minutes to 2 hours after exerciseInvolves the use of water to relax, sooth pain and assist metabolic recovery.Helps relieve swelling, reduce muscle tension, assist in eliminating toxic by-products, and promotes flexibility. Focus on body and mental relaxation.Replenishment of fluid lost through exercise.Cool-downHydrationFuel RecoveryHydrotherapyMassageCryotherapyRelaxationRecovery Strategies – Ken Wallace (Slide 14)Activity 8:Complete the following question: Why would elite athletes use a range of recovery strategies?Take Home ActivitiesTypical Exam-style QuestionsExamine the physiological adaptations in response to training.Explain how increased stroke volume advantages an endurance athlete.Discuss the changes to the cardiorespiratory system, as a result of training, that cause increased stroke volume.Discuss how performance improves as a result of physiological adaptations to training.Investigate the benefits of neural strategies to recover from intense pare the physiological adaptions of an elite athlete and an untrained person in response to training.Justify why elite athletes would use a range of recovery strategies.An athlete has a series of high intensity competitions over a 3 day period. Recommend three recovery strategies that they could employ to assist with their performance.2082800211455-355602603500222253746500Supplementary MaterialCalder, Angela.
