7 Arteries Veins Blood pressure: What is it? Systolic (systole) Diastolic (diastole)

8 Resting Heart Rate (RHR) Maximum Heart Rate (HR Max or MHR) Heart Rate Reserve (HRR) Stroke Volume Cardiac Output VO2 Max (Maximal Oxygen Consumption) Frank Starling Law of the Heart

9 ATP (adenosine triphosphate) What? Where? How? Mitochondria

10 Immediate Energy System ATP-PCr phosphocreatine Nonoxidative (anaerobic) Energy System Lactic Acid System Anaerobic Glycolysis Oxidative (aerobic) Energy System

19 Bob weighs 220 lbs or 100 kg with 20 % body fat (2.2 lbs = 1 kg) Bob’s VO2 = 40 ml/kg · min What effect would a 10% weight lose have on Bob’s VO2 Max? 4L / 100 kg = 40 ml/kg · min 4L / 90 kg = 44.4 ml/kg · min Bob starts training and gains a 20% improvement. What is his VO2 Max? 44.4 X 20% = 8.88 + 44.4 = 53.3 ml/kg · min

20 WHAT? WHEN? WHY?

22 Two male runners are competing in a 10 K race (6.2 miles) Each has a VO2 Max of 40 ml/kg · min. Runner A’s lactate threshold is 70% of his VO2 Runner B’s lactate threshold is 85% of his VO2 All things being equal who will win? A. 40 ml/kg · min X 70% = 28 ml/kg · min B.40 ml/kg · min X 85% = 34 ml/kg · min Winner B !!!

24 2. Health Benefits a.  Risk of Heart Disease b.  blood pressure c.  high density lipoprotein (HDL) cholesterol d.  low density lipoprotein (LDL) cholesterol e.  body fatness (easier weight control) f.  risk Type 2 diabetes) g.  bone density h.  immune function i.  long term quality of life

25 3. Muscular adaptations a.  size and number of mitochondria b.  ability to use fat for energy c.  size of muscle fibers being trained d.  capillaries e.  muscle tone and endurance

26 4. Emotional Benefits a.  anxiety and depression b.  feelings of well being (self-esteem) c.  work, recreational, and sport performance d.  improved sleep e.  easier weight control
