Total questions: 10
Worksheet time: 8mins
Adrenaline is released causing an anticipatory rise. Why does this occur?
To increase glucose metabolism
To increase blood flow for glucose delivery
To decrease the removal of waste products
To increase the removal of waste products
Q is
The amount of blood pumped out of the heart
The amount of blood pumped out of the heart in one beat
The amount of blood pumped out of the heart in a minute
Q = SV + HR
The heart rate remains elevated after exercise has finished. This is to;
Repay the blood debt
Repay the oxygen deficit
Continue to deliver H+
Because it takes time for the heart to reduce its beating speed
Redistribution of blood is;
The shunt of blood from an area of inactivity to an area of activity for improved oxygen and nutrient delivery
To distribute oxygen to the muscles
Vasodilation and constriction (opening and closing of the blood vessels)
Vasicular shunting
Complete the term ventricular ? (contraction of the ventricles)
(a)
Complete the term ventricular ? (relaxation of the ventricles)
(a)
Exercise produces heat. This is redistributed to the ? to allow heat to be radiated out.
(a)
Isometric contraction increases blood pressure. This occurs when
blood flow increases due to high intensty
blood flow decreases due to non aerobic activity
blood flow is prevented due to increased resistance
blood flow is resistant
What is the name for the receptors detecting blood pressure?
(a)
If cardiac control systems (redistribution, blood flow) were not regulated, performance would deteriorate and players would not be able to sustain their level of intensity. What is the terms used to describe this?
(a)
