Flashcards in Phys: excercise & sports phys Deck (15)
1

strength dteremined by

size of muscle

2

power determined by

measured by total amt of work in a period of time

3

endurance determined by

measured by nutritive support

4

high energy phosphate bond?

decomposes to creatine & phopshate ions, releasing large amounts of energy

5

ATP

energy transfer from phosphocreatine to ATP occurs quickly

6

phospagen energy system

cell ATP+phosphocreatine, quick bursts of energy 8-10 seconds

7

glycogen-lactic acid system

stored glycogen in muscle splits into glucose for energy

8

glycolysis

anaerobic met. each glucose molecule splits into 2 pyruvic acid molecules= 4 ATP

9

Lactic Acid

lack of air, pyruvic acid converted to lactic acid, causes considerable amount of ATP formation, 1.3-1.6 min

10

aerobic system

oxidation foodstuffs in mitochondria for energy: glu, FA, carbs, AA

11
