| Question | Answer |
|---|---|
| Is there are target zone that is better for losing weight? | No, it is the overall calorie usage that determines weight lose, the body re balances itself after working out. |
| At a higher exercise intensity what is the most used fuel? | Muscle glycogen |
| Muscle glycogen, PCr as fuel | High intensity, Anaaerobic |
| Glycogen, triglycerides as fuel | Moderate exercise, 60-90% |
| Blood glucose, fatty acids as fuel | Low intensity |
| Speed walkers would not ingest | Creatine |
| What is the best fuel source, but not a lot is available due to osmotic reasons? | blood glucose (depleted at 2 grams/ minute at high intensity= 15 minutes worth) |
| Two Things Liver Does During Exercise: | 1. Glycogenolysis: breakdown of glycogen 2. Gluconeogenesis: de novo Synthese of glucose |
| Occurs early in exercise in the liver | breakdown of glycogen |
| As a person exercises ___________ decreases, while __________ and ____________ increase | insulin, glucagon, catecholamines |
| The liver uses (4 hormones) late in exercise to produce glucose | lactate, pyruvate, alaine, glycerol |
| Glycogenolysis | breakdown of glycogen |
| Gluconeogenesis | de novo synthesis of glucose |
| Eating sugar before exercising causes: | Glucose crash and earlier fatigue |
| Drinking an energy drink while exercising: | Prologues the ability to exercise |
| Exercise+High CHO intake | Gylcogen Supercompensation |
| Stage in Exercise: "top up" liver glycogen and plasma glucose | Pre-Exercise |
| Stage in Exercise: Sports drink, minimize drop in blood glucose during exercise | During Exercise |
| Stage in Exercise: Replenish Liver and Muscle Glycogen stores rapidly | Recovery |
| Diabetes Mellitus | Excessive Sweet Urine |
| Most Common type of diabetes, impaired tissue response | Type 2 |
| Insulin deficiency | Type 1 |
| Hyperglycemia | Primary sign of diabetes |
| Blood sugar levels stay high, and are above normal levels | Diabetes |
| Glucose uptake by contracting/exercising ________ impaired in diabetics. | DOES NOT Slide 35 |
| Glucagon administration may be neccesary, will lead to rapid hypoglycemia | Over-Insulinized (type 1) |
| Rapid hyperglycemia | under-insulinized (Type 1) |
| Exercise improves insulin sensitivity | Type 2 |
| Reduced performance in ____________ exercise but not in ______aerobic exercise | high intensity, aerobic exercise |
