ATP by itself can keep muscles active for about?

when you add the energy of ATP + CP (creatine triphosphate) how long can your physical activities be supported?

3-15 seconds

the first 0-3 seconds of a sprint is powered 100% by?

ATP

after creatine phosphate is used, what is the next source of energy for ATP production?

glucose

glucose supports exercise lasting about how long?

30 seconds-3 minutes

how does glucose provide ATP?

through glycolysis

what is the primary end product of glycolysis?

pyruvate

in anaerobic conditions (limited oxygen) pyruvate is converted too?

lactic acid

if you have excess lactic acid what happens to it?

it is converted back into glucose in the liver (cori cycle)

what is the Cori Cycle?

when excess lactic acid is converted back into glucose within the liver

what are the 4 stages of the Cori Cycle?

lactate

pyruvate

glucose

glycogen

how long are anaerobic activities?

activities lasting up to 3 minutes

36-38

How long are aerobic activities?

3 minutes- 4 hours

after glucose are broken down to produce ATP what is metabolized to produce ATP?

triglycerides or fats

What kind of activities do triglycerides mainly support?

long-term, low intensity activities

hiking/ long distance walking

marathon

what is the primary energy source during sitting resting and standing in place?

triglycerides

how much energy is in triglycerides compared to carbohydrates?

muscle spasms that occur several hours after strenuous exercise

excessive sweating, weakness, nausea, dizziness, headache, and difficulty concentrating are symptoms of?

heat exhaustion and heat stroke

_________ significantly increases our risk for heat illness

dehydration

what are the circumstances i which you should start drinking sports drinks during exercise?
