Tidal Volume x Respiratory Rate

Maximal exercise will result in the following acute respiratory response:

Increased rate of gaseous diffusion at the lungs

A result of participating in a bout of high intensity exercise, which statement is most correct

Increase lactic acid levels, increase muscle temperature

During exercise more blood is directed to the working muscles and this is achieved via:

Vasodilation of capillaries supplying muscle

30sec of maximal exercise would result in which muscular response?

decreased intramuscular glycogen

During exercise, the maximal stroke volume of an untrained individual is attained:

At sub-maximal exercise intensity

Myoglobin is responsible for:

Transferring oxygen from capillaries into the muscle cell

Platelets pupose in the blood is to:

Assist in forming clots to stop bleeding

Blood volume decreases during exercise as:

A consequence of sweating, therefore a decrease in plasma

Stroke Volume
Blood Volume
Cardiac Output
Venous Return
5
The redistribution of blood flow during exercise increases to the:
Muscles
Liver
Brain
Kidneys
6
What Cardiovascular Acute Response does not usually increase throughout exercise?
Diastolic Blood Pressure
Stroke Volume
Systolic Blood Pressure
Heart Rate
7
Maximal exercise will result in the following acute respiratory response:
Decreased production of CO2
Increased tidal wave output
Increased systemic gaseous exchange
Increased rate of gaseous diffusion at the lungs
8
Acute respiratory responses to exercise do not include:
Ventilation
Tidal Volume
Cardiac Output
Pulmonary Gas Diffusion
9
A result of participating in a bout of high intensity exercise, which statement is most correct
Increase lactic adic levels, decrease muscle temperature
Increase lactic acid levels, increase muscle temperature
Decrease lactic acid levels, decrease muscle temperature
Decrease lactic acid levels, decrease muscle temperature
10
Cardiac Output (Q) is:
Tidal Volume x Stroke Volume
Stroke Volume x Venous Return
Stroke Volume x Heart Rate
Heart Rate x Ventilation
11
The period at the beginning of exercise when O2 demand is greater than O2 supply is known as:
Oxygen deficit
Oxygen discrepancy
EPOC
Oxygen debt
12
During exercise more blood is directed to the working muscles and this is achieved via:
Vasoconstriction of capillaries supplying the heart
Vasodilation of capillaries supplying muscle
Vasodilation of capillaries supplying the heart
Vasoconstriction of capillaries supplying muscle
13
30sec of maximal exercise would result in which muscular response?
decreased intramuscular glycogen
Decreased lactate levels
Increased use of free fatty acids
Increased glycogen stores
14
Acute responses to exercise occur:
During exercise
In the recovery of exercise
Prior to exercise
All of the above
15
During exercise, the maximal stroke volume of an untrained individual is attained:
At maximal exercise intensity
At sub-maximal exercise intensity
Immediately as exercise begins
The stroke volume remains relatively unchanged
16
Myoglobin is responsible for:
Respiration and the aerobic production of energy / ATP
Breaking down glycogen
Transferring oxygen from capillaries into the muscle cell
Transferring CO2 back into alveoli from the blood
17
Platelets pupose in the blood is to:
Watery part of the blood
Transport O2 (haemoglobin), CO2, nutrients and waste
Assist in forming clots to stop bleeding
Fight disease
18
What is the only muscular acute response to decrease during exercise?
Blood flow to muscles
Motor Unit and muscle fibre recruitment
Lactate production
Energy substrates
19
What is the average persons breaths per minute at rest?
6-10
20-25
12-15
30-35
20
Blood volume decreases during exercise as:
There is an increase in O2 being delivered to working muscle
Lactate begins to accumlate faster than removal rate
There is an oxygen deficit
A consequence of sweating, therefore a decrease in plasma
