aerobic fitness - - atp for longer than 3 minutes - 1 min-3 min - both systems - tests walk, jog, run, step, cycle - >60 minutes (long) 3-30 minutes (short) • cardiorespiratory fitness (VO2max) • cardiovascular function • respiratory function •nutrition and hydration anaerobic fitness - - atp - 3 systems: stored ATP, phasphagen (PC system), & glycolytic system - produce atp at Faster rates, but Lower quantities - phasphagen < 15sec immediate effort - glycolytic 30-120se...

A FEV1.0% below 70% indicates the patient likely has - obstructive lung disease A FEV1.0% greater than 80% indicates the patient likely has - restrictive lung disease electrical flow through the heart - SA node -> atria -> AV node -> bundle of His -> purkinje fibers elevated - 120-129 and less than 80 high bp stage 1 - 130-139 or 80-89 high bp stage II - 140 or higher or 90 or higher How can you find stroke volume based on cardiac output and heart rate? - SV = Q/HR how is DBP ...

Energy expenditure from VO2 and VCO2 - Answer-on paper How do you calculate BMI? - Answer-(weight (lbs) * 703)/(ht(inches)^2) How many calories is in a pound? Why is that important? - Answer-3500. If a person knows how many calories they're burning, it could be a good tool for weight loss. How would you define resting metabolic rate? - Answer-The calories being burned outside of physical activity What are the seven skin fold sites and what are their directions? - Answer-1. Abdomen (vertic...

1 lbs = - 0.454 kg 1 MET = - 3.5 ml/kg/min Age predicted max HR = - 220-age BMI eq. - kg/height (m) FEV1.0 % = - FEV1.0/FVC x 100 Fick eq. - VO2= Q x a-vo2 diff MAP = - DBP + (SBP-DBP)/3 Q = - HR x SV RER = - VCO2/VO2 RMR = - VO2 x Caloric equivalent of O2 TPR = - MAP/Q

Anaerobic pathway - a fermentation pathway that operates in the absence of oxygen; glycolysis and lactic acid formation Anaerobic vs Aerobic - Anaerobic: stored ATP, creatine phosphate sytem, glycolysis Aerobic: Krebs cycle, electron transport chain Creatine phosphate system - The energy pathway that consists of adenosine triphosphate (ATP) and phosphocreatine (PC); provides immediate energy (between 10 and 15 seconds) through the breakdown of these stored high-energy phosphates.
