Hypothesis Procedure - 1. Hypothesis 2. Level of Sig 3. Subjects & Data 4. Statistical Method 5. Fail to reject/reject null Hypothesis - null research (alternative) Level of Sig - p<0.05 Statistical Method - -excel gives you R-value (pearson correlation) -find degrees of freedom (npairs-2) -find critical correlation value -finally, compare R-value (absolute value) and critical value |R|>critical value - statistically significant correlation -if R is positive it's direct/vice ...

Where is muscle taken from for glycogen measurements? How much glycogen do we have total stored (g)? How much do we have in muscles and how much do we have in the liver? How much do we have in the legs? - Answer-Calf muscle. We have about 400g total, 350g in muscles and 50g in the liver. Most muscle is in the legs so we might have 250g of glycogen in the legs alone. What is the classic method of glycogen loading? - Answer-Day 1: exhaustive exercise Day 2 + 3: Fat and protein only. Day 4, 5...

Blood Distribution at Rest - Brain: 13%, 720 mL Muscle: 21% 1200 mL Skin: 8.5%, 500 mL Kidneys: 19%, 1100 mL Abdomen: 24%, 1400 mL Heart: 4%, 250 mL If you measure systolic blood pressure, when would it be highest, standing, sitting or lying down? - standing Systolic pressure - It is the maximum pressure your heart exerts while beating Diastolic pressure - The pressure in the arteries when the heart is at rest If you measure systolic, when would it be lowest, standing, sitting or lying...

Drug Categories - Answer-1. anabolic agents 2. stimulant 3. recreational drugs 4. diuretics Anabolic Agents - Answer-mimic testosterone; not available prior to 1960's Dianabol (Ciba labs) - Answer-first commercially available anabolic steroid (1959) Systems Affected (AA) - Answer-affect the liver/cardio system the most. HGH - Answer--Anabolic Agent -Human Growth Hormone; -not as potent as AS -decreases body fat, increase FFM -Body normally produces it's own -excessive amounts can c...

Number of times ventricles contract per minute - Heart Rate Volume of blood ejected by each ventricle Per beat (L/B) - Stroke Volume Volume of blood ejected by each ventricle per minute - Q (cardiac Output) HR (b/min) x SV (L/b) - Q (L/min) calculation 5L & goes around the body once at rest - How many liters of blood in body? 70 - Resting BPM 5 L/M = 70 bpm x ~ 72 ml/beat - Sedentary Values at Rest 5 L/M = 50 bpm x 100 ml/beat - Endurance Trained Values at res
