Fitness Physical Activity Fitness Surgeon Generals Report (Centers for Disease Surgeon Control, 1996) Effects of Regular Exercise Effects Improved cardiorespiratory function Reduction in Heart Disease Risk Factors Decreased Mortality (death) and Morbidity (disease) Improved psychological functioning What are the risks of exercise? What Injury? Injury? Myocardial Infarction Myocardial (heart attack)? Death? Death? How do you minimize risk? How ESTABLISH A PLAN! Medical Clearance and Follow-up Health Screening Health Physical exam Proper warm-up and cool-down Take special consideration to the Take environment environment How do I screen myself? How Physical Activity Readiness Questionnaire (PAR-Q*) Also referred to as Health Status Questionnaire See also Laboratory 2.1 Do I need a physical exam? What other aspects should I consider? Diagnoses Hospitalizations/ Surgery Medications (action, dose) Taking meds regularly Family History Physical Activity History Revised Physical Activity Readiness Questionnaire (PAR-Q) Yes 1. Has a doctor ever said that you have a heart condition and recommended only medically supervised activity? Yes No 2. Do you have chest pain brought on by physical activity? Yes No 3. Have you developed chest pain in the past month? Yes No 4. Have you on one or more occasions lost consciousness or fallen over as a result of dizziness? Yes No 5.

If you answered "yes" to any of these questions, call your personal physician or healthcare provider before increasing your physical activity. No How do we measure cardiorespiratory fitness? fitness? Concept of VO2max (VO2max) Criterion measure of cardiorespiratory fitness “endurance capacity of the cardiorespiratory endurance system and the exercising skeletal muscles” system How is VO2max measured? Maximal Test – VO2max and Stress Testing Maximal VO Submaximal Tests – Use heart rate response to exercise Submaximal (assumptions) to predict VO2max VO VO2max and Stress Testing VO Terminology specifically refers to an exercise test Terminology usually conducted on a cycle ergometer or treadmill lasting approximately 8 to 12 minutes in length in which an individual must exercise to “maximal” point. VO2 max: Amount of oxygen consumed, highest heart rate reached, Amount subjective rating of effort, amount of lactate produced subjective Stress Test Looking for abnormal responses in heart rate and rhythm Looking (ECG) , blood pressure, and symptoms (ECG) Physician is usually present VO2max and “Stress” Testing VO2max and “Stress” Testing VO Electrocardiogram (ECG/EKG) – tells abou Electrocardiogram (ECG/EKG) (ECG/EKG) - tells about the electrical activity in the heart and is used as a tool for diagnosing some types of heart disease tool How exercise ECG is used in stress testing How exercise ECG is used in stress testing testing How do we measure cardiorespiratory fitness? Submaximal tests for measuring cardiorespiratory fitness cardiorespiratory 1.5 mile run test (Table 3.1) - idea is to complete the distance in the shortest time possible the 1 mile walk test (Table 3.2) – idea is to walk the distance as fast as possible distance Cycle ergometer tests (Table 3.3-.4-.5) - base Cycle ase fitness on heart rate response to exercise fitness Step Test (Fig. 3.6) – fitness is based on recovery heart rate from 3 minutes of stepping heart Cardiorespiratory Fitness: What do I do with the results? What Use normative percentile values to give Use you and idea of your fitness (Table 3.1 - 3.6) Superior rating for any of the tests Superior equates to the top 15% for your age and gender and Discussion: Who or what has the highest cardiorespiratory fitness? highest ...
