5 Activity 3: AFL Musculoskeletal Pre-screening Discuss what the AFL is doing to prevent injuries. Use the following questions as cues: Why does the AFL conduct musculoskeletal pre-screening in junior players? How does this benefit junior players? What impact does this have further in the elite athlete s career? Page 69

6 Skill and Technique Slide 10 Activity 4: Skill and Technique to Prevent Injury. Use the images as cues to provide sporting examples of how adequate and correct skill and technique can prevent injury. Image 1: Image 2: Page 70

7 Physical Fitness Slide 11 Activity 5: Skill and Technique to Prevent Injury. Construct a mind map outlining the various components of physical fitness. Provide an example of sports that require an adequate level of each component. Page 71

8 Warm Up, Stretching and Cool Down Slide 12 General Body Warm-up Phase Activities Benefits increased blood flow raised muscle temperature Stretching Callisthenics Skill Rehearsal increased elasticity increased muscle extensibility strengthens muscle draws blood from internal organs to skeletal muscle increased agility game readiness maintenance of body temperature Page 72

9 Activity 6: Warm up and stretching. Complete the table with activities that can be used by athletes for each of the phases of warm up and stretching. Stretching Slide 13 Activity 7: Stretching Complete the following questions to develop a deeper understanding of the purpose of stretching: Why stretching is important? How it is done/what elements are involved? What movements should be avoided? Page 73

10 Temperature Regulation Slide 16 PDHPE HSC Enrichment Day 2016 Sports Medicine Activity 8: How heat is lost in athletes. In pairs, brainstorm when each form of heat transfer may occur in an athlete, in a particular sport. Add an example of a strategy the athlete in each scenario can use to manage heat loss. Page 74

11 Climatic Conditions Slide 18 Activity 9: Climatic conditions and their impact on performance. In pairs, discuss how each of the 5 climatic conditions impact on the safe participation of an athlete? What may each result in? Page 75

12 Guidelines for Fluid Intake Slide 19 Acclimatisation Slide 20 Page 76

13 Activity 10: Acclimatisation to hot, humid conditions. In groups of 3-4, use examples to state the techniques that can be used by athletes to acclimatise to hot, humid conditions. Page 77

19 Take Home Activities The following activities can be done at home as part of your study in preparation for the HSC: Activity 1: Physical Preparation. Complete the following table to comprehensively determine the importance of each of the elements of physical preparation for athletes in a range of sports. Element of physical preparation Sport 1 Sport 2 Sport 3 PRE-SCREENING SKILL AND TECHNIQUE PHYSICAL FITNESS WARM UP, STRETCHING AND COOL DOWN Analyse the role of physical preparation in enhancing the wellbeing of the athlete 8 marks. Students learn to: Analyse different sports in order to determine priority preventative strategies and how adequate preparation may prevent injuries. What does analyse mean? What elements from the dot point need to be included? Acronym? What sport example/s will you use? What needs to be identified? Described? Explained? Have you created links between each element to ensure it is an analysis? Page 83

20 Activity 2: Read the Beat the Heat fact sheet produced by Sports Medicine Australia. This can be found at What is heat stress? Signs/Symptoms? Outline factors that increase the risk of heat illness? What can be done by players and coaches to reduce the risk of heat stress? Why are children more at risk of heat related illness? How is heat illness treated? Page 84

21 Activity 3: Read the following article outlining the measures that Tennis Australia took at the Australian Open in 2014 when temperatures soared to 43 degrees celcius. Research Tennis Australia s current heat policy and outline the current changes. that have been made? Australian Open tournament referee implements extreme heat policy January 16th 2014 Michael Chammas, Beau Donelly Almost 1000 tennis fans have been treated for heat exhaustion at the Australian Open as soaring temperatures forced the suspension of nearly all matches on day four. Tournament referee Wayne McEwen applied the extreme heat policy at Melbourne Park about 1.52pm on Thursday, suspending all play on outdoor courts. Not long after 6pm play was resuming on the outside courts. Temperatures hit 43.3 degrees on day four of the grand slam and Mr McEwen deemed the conditions unsafe for players. It is the first time the extreme heat policy has been applied at the Australian Open since 2009, when the tournament was suspended on consecutive days with temperatures reaching as high as 45 degrees. Victorian Emergency Services Minister Kim Wells said St John s Ambulance staff had treated 970 people for heat exhaustion at the tournament so far. While players on the outside courts retreated to the shade once they had finished the sets under way, matches on Rod Laver Arena and Hisense Arena continued once the roofs on both courts had been closed. This year the extreme heat policy was modified to give the tournament referee more discretion about stopping play when the temperature has exceeded a predetermined threshold. At the time the suspension was announced, No.3 seed Maria Sharapova and Italian Karin Knapp were locked in a tense final-set decider, having been on court for nearly three hours. They played for a further 50 minutes after the announcement before Sharapova eventually triumphed 10-8 in the third set. The extreme heat policy is applied when the Wet Bulb Globe Temperature exceeds a predetermined threshold, allowing the tournament referee to suspend play at his discretion. Given the extreme heat in Melbourne, women in the singles draw have already been allowed a 10-minute break between the second and third sets and ice vests are being provided on all courts. Matches interrupted because of the extreme heat policy included Jo-Wilfried Tsonga's match against Thomaz Bellucci and Andreas Seppi's match again Donald Young. The Tsonga-Bellucci match restarted when the roof was closed on Hisense Arena. Earlier, Mr McKewen had said that while conditions so far had not warranted the extreme heat policy to be implemented, today may be a different story based on forecasts. Speaking to Melbourne radio station 3AW, Mr McKewen said weather conditions were being continually reassessed and that he was in regular contact with the tournament's chief medical doctor and the Bureau of Meteorology, which has set up a temporary base at Melbourne Park. The forecast top for Melbourne on Thursday is 44 degrees. Friday is expected to reach 42 ahead of a gusty change. We've got staff in the tournament control who are continually monitoring the weather conditions, he said, adding that ambient air temperature, humidity and wind variation were all considered. Mr McKewen said he was confident the regulations protected players' health and safety, despite the phrase predetermined threshold being removed from the tournament's heat policy earlier in the week. I've got guidelines which I follow, he said. We don't want to have a hard mark as to, OK if it hits this we stop play. "Because we all know in Melbourne temperatures can fluctuate very quickly, and if we know it's going to cool down in the next half an hour or so we'll push through that period and then continue on into the cooler period. But if I know the temperatures will spike I would rather bring everyone in earlier rather than later. We want to have that little bit of flexibility for the players. Nine players retired in the first round, some due to heat. Page 85

22 Do you think this heat policy is adequate? Too harsh? Why? Considering the nature of the sport at the elite level, what are some of the consequences of players competing in extreme weather? Activity 4: Page 86
