VCE PE Unit 1 The Human Body in Motion Outline 2017UNIT 1 AOS 2Area of Study 2: How does the cardiorespiratory system function at rest and during physical activity?Outcome 2:On completion of this unit students should be able to collect and analyse information from, and participate in, avariety of practical activities to explain how the cardiovascular and respiratory systems function and the limitingconditions of each system, and discuss the ethical and performance implications of the use of practices andsubstances to enhance the performance of these two systems.Term/WeekKey knowledgeKey skillsTeaching and Learning ActivitiesChapter 51.8the structure and function of the cardiovascular system, including the structure and function of the heart andblood vessels and blood flow around the body at rest and during exerciseuse and apply correct anatomical terminology to identify the structures and function of the cardiovascular andrespiratory systemsRead p.97-99 NelsonWatch QUICKVID P.99Participate in continuous activity eg. 20 minute run, cycle or swim (6)components of blood, including red blood cells, white blood cells, platelets and plasma and their function atrest and during exercisedescribe the role and function of blood componentsRead p. 101-102 NelsonWatch QUICKVID p.102Read p.103 and watch QUICKVID p. 103Read p. 104-105 and watch QUICKVID p.105Participate in prac lab similar to LAB in Nelson p. 107vasodilation and vasoconstriction of the blood vessels to regulate blood distribution at rest and during exercisethe role of the cardiovascular system in thermoregulation: homeostasis, hyperthermia and hypothermiaexamine the role of the cardiovascular system in thermoregulation(Thermoregulation) Critique Sports Medicine Australia’s heat policy p.108-111 NelsonLook at INVESTIGATION Nelson p.111Watch QUICKVID p.111Chapter 61.9the relationship between stroke volume, heart rate and cardiac output at rest and during submaximal andmaximal exerciseanalyse the relationship between stroke volume, heart rate and cardiac output at rest and during submaximaland maximal exerciseParticipate in a submaximal activity (brisk walk for 20 minutes) and a maximal activity (sprints) (7)the structure and function of the respiratory system, including the structure and function of the lungs, mechanicsof breathing and gaseous exchange at the alveoli/capillary and the capillary/muscle interfacedescribe the process of gaseous exchangeBuild a working model of the lungs rate and exercise laboratory activityRead p.117-119Watch QUICKVID p.118 and 119Read p.120-121Watch QUICKVID p.121Read p.122-123Watch QUICKVID p.123the interrelationship of the cardiovascular and respiratory systems to transport oxygen around the body at restand during exerciseperform, measure and report on changes to the cardiovascular and respiratory systems at rest compared withexerciseMaybe do LAB p.1241.10physiological, social, cultural and environmental enablers and barriers of cardiovascular health (such asatherosclerosis, coronary heart disease, high cholesterol levels, hypertension and stroke) and respiratory health(such as chronic obstructive pulmonary disease)assess enablers and barriers to cardiorespiratory health and investigate strategies to enhance the capacity andfunctioning of cardiorespiratory systemLung function laboratory (link to COPD)Yoga breathing to improve respiratory health p.130-139 – Need to get some youtube clips and interesting stuff to break this up.ATHERSCLEROSIS - - LOWERING CHOLESTEROL - (Boring but informative) – students write out their daily diet and re-write it with suggested foods. OR access - SURGERY PREVENT HEART ATTACK - AND STROKE - HEART DISEASE - role of physical activity, sport and exercise to enhance the capacity and functioning of the cardiovascularand respiratory systemsParticipate in a community based exercise program such as Heart Foundation Walking (8) and perceived benefits and potential harms to the athlete of legal and illegal substances and methodsthat enhance performance of the cardiorespiratory system, such as altitude training, erythropoietin (EPO),beta-blockers and blood dopingcritically analyse the physiological effects of legal and illegal strategies that enhance the performance of thecardiorespiratory system on the individualChapter 82.1ethical and sociocultural considerations associated with the use of illegal practices associated with improvingthe function of the cardiorespiratory systemdiscuss the ethical, social and cultural considerations associated with the use of legal and illegal practicesassociated with improving the function of the cardiorespiratory system.Debate the perceived vs real benefits of altitude training for endurance athletes.Read p.145-147Watch INVESTIGATION p.147Read p.148-154 and watch some clips appropriate to these methods.IMPORTANT NOTE: CORE SAC task – written report analysing participation in at least four physical activities that demonstrate how the musculoskeletal, cardiovascular and respiratory systems work together to produce movement:-* practical activities 1–8 above provide appropriate contexts for students to collect data for analysis in the SAC task – i.e. volleyball game, baseball game, resistance circuit, force production lab, hockey/cricket/soccer game, continuous run/swim/cycle, brisk walk v’s sprints, community-based program (e.g. jump rope for heart.* What we’ve done so far: resistance circuit, basketball game, ................
