1

list 8 health benefits associated with regular exercise

lower risk of coronary heart disease,lower risk of high blood pressure, type 2 diabetes, breast cancer risk reduced depression, improved cardiorespirtatory and muscular fitness, prevention of weight gain

2

how can interval training improve aerobic preformance

maximize aerobic power and minimize boredom

3

list 3 physiological adaptations that occur to improve xercise preformance

increased max blood flow (increases stroke volume), increased oxygen delivery and CO2 removal, increaed maximal oxygen uptake and aerobic power

4

define energy and its food source

the ability to do work and source is sun

5

what is an intercellular carrier of chenical energy produced by the body for mulscar work

adenosine triphosphate ATP

6

list 2 energy pathways

Anaerobic and Aerobic

7

anaerobic path way ATP CP- Fuel source, intensity, duration, 3 examples of activites that utilize this system

creatine phosphate, very high intensity, 1-15secs,sprinting, jumping, kicking

8

anaerobic pathway lactice acid system fuel source, intesnity, duation, example

carbohydrate only, high intensity, 45-90sec, prolonged sprints, swimming, cycling

9

Aerobic pathway fuel source, intensity, duration, example

carbs, protein, fat, moderate to low intesnity, >5 mins, cross country, walking, sleeping, biking

10

define aerobic

requires oxygen

11

define anaerobic

does not require oxygen

12

Steady State

After beginning exercise, the oxygen uptake meets the oxygen demands, usually 3-4 mins after exercise, cardiac output and heart rate and pulmonary ventilation are constant

13

Excess Post oxygen COnsumption

after exercise has stopped, there is still elevated intake of oxygen for several minutes during recovery

14

Oxyge Deficit

period in which the level of oxygen consumption is below what is necessary to supply ATP production

15

Anaerobic threshold

when body can no longer meet its demand for oxygen and must undergo anaerobic metabolism

16

Aerobic Capacity

ability of body to remove oxygen from the air and transfer it to working muscles (related to cardiorespiratory endurance)

17

Lactic ACid

Byproduct of anaerobic metabolic pathway

18

Aerobic vs. Anaerobic

Aerobic-complete breakdown of glucose, use of carbs, fat, protein, long duration activity, smaller EPOC. Anaerobic-partial breakdown of glucose, only carb, short duration, greater EPOC

19

Stroke Volume

Amount of blood pumped per heart beat-volume of blood ejected by each ventricle of te heart during asingle systole

20

Cardiac output

volume of blood pumped by each ventricle in one minute

21

Venous Return

Pumping action of the muscles in extremeties and respiratory system along with venoconstriction to moe oxygen poor blood back to heart

22

Blodd Polling

condition caused by ceasing vigorous exercise too aburptly so that blood reamins in the extremities and not deliverd to heart

23

Vital Capacity

Greatest volume of air that can be forcibly exhaled after deepest inhalation

24

Valsalva Maneuver

Danverous condition that can occur if an individual holds their breath forming an unequal pressure in the brain

25

Blood pressure for normal person? too high?

120/ 80 is good. 140/90 is bad!

26

Joint

Where two bones meet

27

Ligament

attaches bone to bone, fibrous tissues

28

Tendon

Attaches muscle to bone,dense fibrous tissue, not very elastic

29

Cartliage

connective tissue that cushions the articular surfaces

30

Anterior/Posterior

Front and back of body
