Q

List the steps in the cardiorespiratory function starting with inhalation (9)

A 
Inhalation mafia nose and mouth
Through the bronchi
To the lungs to the alveolar sacs
Blood is pumped to the right ventricle 
Thought the pulmonary arteries to the lungs
Blood becomes oxygenated 
Pumped out through the pulmonary vines to left atrium
Pumped to left ventricle
Pumped out of body to body tissues

Q

Adenosine triphosphate (ATP)

A

A cellular structure that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis

17
Q

The energy needed for muscle contraction

A

ATP

18
Q

ATP has the ability to store large amounts of energy, however the supply of ATP in each cell is limited, therefor cells must have a means of producing more. There are 3 main bioenergetic pathways that produce ATP, what are they?

A

ATP-CP creatine phosphate (anaerobic)
Glycolysis (lactic acid) (anaerobic)
Oxidative (aerobic)

19
Q

Collectively ATP-CP creatine phosphate (anaerobic)

Glycolysis (lactic acid) (anaerobic) Oxidative (aerobic) are known as the

A

bioenergetic continuum

20
Q

Together ATP and CP (creatine phosphate) are called

A

Phosphagens system

21
Q

Which system provides energy for high intention, short intensity duration bouts of exercise (10 seconds) example, heavy weight training

A

ATP-CP

22
Q

Which energy system is used for power and strength training using heavy loads, few reps, or a short sprint

A

ATP-CP

23
Q

Why is the ATP-CP system limited in it’s capacity to sustain energy production (10) seconds

A

Because it must rely on minimal storage of ATP and CP within the cells

24
Q

Which energy system utilizes the breakdown of carbohydrates (glucose) to rapidly produce ATP

A

Glycolysis (anaerobic lactic acid)

25
Q

One glucose molecule will produce 2 ATP through anaerobic glycolysis, what is the byproduct of this?

A

Pyruvate

26
Q

What happens if the muscle cell can not utilize the pyruvate fast enough?

A

A build up of lactic acid will occur

27
Q

What causes an increase of acidity of the muscle cell and interferes with muscle contraction?

A

Excess lactic acid

28
Q

The glycolysis (anaerobic lactic acid) energy system produces energy for how long?

A

30-50 seconds or 8-12 reps

29
Q

Most exercise programs use which energy system in the biogenetic continuum?

A

Glycolysis (anaerobic lactic acid)

30
Q

What does the oxidative (oxygen) system rely on for ATP

A

Carbohydrates and fat

31
Q

Why is the oxidative (oxygen) system the slowest of the three systems?

A

It requires increased amounts of oxygen to match the muscular requirements of the exercise, oxygen is supplied via respiration and takes a while to elevate and therefore consume the required amounts Of oxygen

32
Q

One glucose molecule produces how much ATP

A

2

33
Q

Which energy system produces the greater amount of ATP?

A

Oxidative (oxygen)

34
Q

In the oxidative system how much ATP does one molecule of glucose produce.

A

36 ATP

35
Q

Breathing dysfunction is a very common predecessor to kinetic chain dysfunction. It often results from breathing associated with what?

A

Stress or anxiety

36
Q

Common health complaints that are caused by breathing dysfunction (5)

A

Headaches, anxiety, fatigue, poor sleep patterns, poor circulation

37
Q

If breathing patterns become more shallow (breathing dysfunction) the body uses secondary respiratory muscles more than the diaphragm. How does this negatively effect the body?

A

Negatively effects posture

38
Q

Short shallow breaths can lead to altered carbon dioxide oxygen blood content resulting of feelings of what?

A

Anxiety

39
Q

What is the effect of inadequate oxygen and retention of metabolic waste within muscles?

A

It can created stiff muscles and joints
