Flashcards in Semester 1 exam revision Deck (27):
1

Define pulmonary ventilation

Breathing

2

Define respiration

The process of gas exchange between lungs and the blood

3

Define ventilation

The volume of air breathed in and out per minute (tidal volume x breathing frequency)

4

Define tidal volume

Amount of air breathed in or out per breath

5

Define vital capacity

Volume of air forcibly expired after maximum inspiration of one breath

6

Define ventilation breakpoint

The point during intense exercise at which ventilation increases disproportionally to the oxygen consumption

7

What is Dalton's law of gases?

The partial pressure of nitrogen, oxygen and carbon dioxide add up to atmospheric pressure

8

What is Henry's law of gases?

Gases dissolve in liquids in proportion to their partial pressures, depending on there solubility in the specific fluids and depending on temperature

9

When are the internal intercostals used?

Expiration during exercise

10

What causes the Bohr effect?

Lower pH during exercise

11

Blood pressure equation

Cardiac output x total peripheral resistance

12

Define cardiac output

Total volume of blood pumped by the ventricle per min
HR x SV

13

Define steady state heart rate

Heart rate plateau reached during constant rate of sub maximal work

14

What is the PCr system equation

PCr + ADP + H ----> ATP + Cr

15

Define glycogenesis

Creating glucose

16

Define glycogenolysis

Creating glycogen

17

Define anaerobic power

The peak rate at which ATP can be replenished anaerobically

18

Define anaerobic capacity

The total amount of ATP that can be replenished anaerobically

19

What are the three main ways of assessing biological maturation?

Skeletal, sexual, somatic

20

What is the equation for V02

Q x a-v02 diff

SV x HR x arterial o2- venous 02

21

Order of carbohydrate size smallest to largest

Monosaccharide
Diaccharide
Oligosaccharide
Polusaccharide

22

Define hyperinsulinaemia

The consequence of eating a pre exercise snack which is high in simple carbs

23

Define strength

The ability to produce force

24

Name the 4 primary ways which the neurones adapt from resistance training

Motor unit synchronisation, increased rate coding of motor units, increased neural drive, autogenic inhibition

25

Factors which effect the velocity of an action potential

Large diameter neurons conduct nerve impulses faster
They present less resistance to current flow
Saltatory conduction: potential travels quickly from one break in myelin to the next

26

What is excitation contraction coupling?

The process of converting the electrical signal from a motor neuron into a muscle contraction

27

Where is calcium released from?

Sarcoplasmic reticulum
