Q

VO2

A

Volume of oxygen consumed at a given workload. ONLY WHAT HAS BEEN CONSUMED BY LUNGS. Measures aerobic fitness (mlO2/kg/min)

Q

Anaerobic Threshold

A

Onset of blood lactate accumulation. It is the point at which the extra energy for exercise must come from anaerobic sources and therefore increase blood lactate

Q

MET

A

One MET is equal to the resting metabolic rate of 3.5 ml O2/kg/min.

To get mets from VO2 divide your VO2 by 3.5

19

A 
Cardio Respiratory Fitness
Musculoskeletal Strength 
Musculoskeletal Endurance 
Musculoskeletal Flexibility 
Body Comp
21
Q

Current ACSM/AHA Recommendations

A

Mod Cardio 30 mins 5 days a week
Vigorously intense Cardio 20 mins a day 3 days a week
8-10 strength training exercise for 8-12 reps 2x a week

22
Q

C.G Douglas

A

Douglas Bag

23
Q

Dr. Dudley Sargent

A

Harvard Hired him to help improve fitness of students

24
Q

Acute Responses

A

How body responds to individual bouts of Physical Activity

25
Q

Chronic Adaptations

A

Mark how the body responds over time to the stress of repeated bouts of exercise, referred to as training effects

26
Q

Carbohydrate

A

Short and long term systems

27
Q

Protein

A

Function depends on amino acid

28
Q

Fat

A

Glycerol: Short and long term systems

Fatty Acids: Long term system only

29
Q

Oxygen Deficit

A

The difference between oxygen uptake of the body during early stages of exercise and during a similar duration in a steady state of exercise

30
Q

Oxygen Debt

A

the extra oxygen that must be used in the oxidative energy processes after a period of strenuous exercise to reconvert lactic acid to glucose and decomposed ATP and creatine phosphate to their original states.

31
Q

Ventilatory threshold…

A

Predicts anaerobic threshold

32
Q

Relative Oxygen Consumption

A

Dividing oxygen consumption by your body weight

33
Q

Absolute Oxygen Consumption

A

However much oxygen you can put into your body

34
Q

Maximum oxygen consumption

A

The total amount of oxygen you can take in your body

35
Q

Total daily energy expenditure

A

10% feeding
60-75% RMR
15-30% Physical Activity

36
Q

Cell Structure

A

Cell Membrane: Semipermeable (Glucose)
Nucleus: Genetic Material
Cytoplasm: Anaerobic Processes
Mitochondria: aerobic processes (POWER HOUSE)

37
Q

Substrates

A

Carb(4 kcal/g)/Fat(9 kcal/g)/Protein(4kcal/g)

38
Q

Bioenergetics

A

Converting substrates to energy and what happens in the cell at this time

39
Q

Metabolism

A

Chemical Reactions in the body

40
Q

1,000 cal

A

= 1 kcal = 1 Calorie (Dietary)

41
Q

Endergenic Reaction

A

Requires addition of energy in order to proceed

storing

42
Q

Exergonic reaction

A

Gives off energy (takes stored and uses it to move and stuff)

43
Q

All Carbohydrate are converted to…

A

Glucose. We use that for energy.

44
Q

Where do you store glucose?

A

Liver and muscle (some in blood)

Most concentrated is in the liver in the form of glycogen
Most total is in the muscle
