Q

Diastolic BP

A

Heart Dilating 80

17
Q

Respiratory system Flow

A

Nose, pharynx, larynx, trachea, bronchi, bronchi oles

18
Q

Metabolism

A

sum of all the chemical processes necessary to maintain the body

19
Q

Metobolic rate

A

the rate at which your body uses energy

20
Q

ATP

A

form of energy our cells use for energy , most efficient for our body to use

-come from glucose, glycogen and fat

21
Q

immediate energy system

A

EXPLOSIVE- provides immediate energy, but for short amount of time

  • up to 10 seconds of activity
  • ATP and Creatine Phosphate
22
Q

Non-oxidative energy system

A

anaerobic- does not require oxygen
-start of high intensity exercise
-lasts 10 -120 seconds
Creates ATP by breaking down glucose and glycogen

23
Q

Limitation of Anaerobic system

A

bodys supply of glucose and glycogen is limited
creates metabolic acid–> fatigue (lactic acid)
-improved fitness allows to exercise longer at higher intensity.
-delays lactic threshold

24
Q

Oxidative System

A

aerobic- requires oxygen in order to create more ATP

  • greater than 120 seconds
  • Does not produce ATP quickly but does create ATP for longer
  • Takes place in the mitochondria
  • Fats are burned during lighted exercise
  • Carbs are burned during more intense exercise
25
Q

VO2 max

A

highest rate of oxygen consumption an individual is capable of during maximum physical effort

26
Q

Benefits of Cardiorespiratory Endurance

A

Improves:

  • Cardiorespiratory functioning
  • Cellular metabolism
  • Immune Function
  • Psychological +Emotional wellbeing
27
Q

Reduces risk of what?

A

Chronic Diseases including:

  • CVD
  • Cancer
  • Type 2 Diabetes
  • Osteoprosis
  • Death from all causes
28
Q

Max Target Heart rate equation?

A

207- (age*0.7)

29
Q

What is the Target Heart Rate Range?

A

65% - 90% Multiply Target Heart Rate by 0.65 and 0.90 to create a range to work in.

30
Q

What is the equation for Heart Rate reserve?

A

HRR= Max HR- Resting HR

31
Q

METs

A

1 MET represents body’s resting metobolic Rate

32
Q

Low intensity in METs
Medium intensity in METs
High intensity in METs

A

Low- 3 to 4 METs
Medium- 6-8 METs
High- Over 10 METs

33
Q

Warm-up

A

Enhances performance and reduces the chance of injury

34
Q

Cool Down

A

returns the body to a non-exercising state

35
Q

ALWAYS INCREASE _____ before ________

A

TIME before INTENSITY

36
Q

Heat Stress Includes

A

Dehydration–> Heat Cramps–> Heat Exhaustion–>Heat Stroke
