Fatigue can be defined as 'muscle tiredness when the body has a lack of energy'.
True
False
When we exercise, our muscles feel warmer due to increased blood flow to muscles
True
False
What waste product is generated in the muscle during aerobic exericse?
Carbon dioxide
Lactic acid
What waste product is produced at the muscle during anaerobic respiration which causes muscles to stop working?
Carbon dioxide
Lactic acid
What happens to heart rate and breathing rate during exercise to remove carbon dioxide and lactic acid?
They stay the same
The decrease
They increase
When we exercise, blood is redistributed to the working muscles from organs of a lesser priority. This is called...
Vascular shift
Vasocontriction shift
Vascular shunt
Vascular buffer
During exercise, more oxygen is delivered to the working muscles. What acts as a 'backpack' for the oxygen and is attached to a red blood cell?
Iron
Calcium
Vitamin D
Haemoglobin
Vasodilation is the process of blood vessels getting smaller to restrict blood flow.
True
False
During exercise, why does tidal volume increase?
To restrict the amount of air going into and out of the lungs.
To enable more air to enter and leave the lungs per breath
Breathing rate x tidal volume =
(a)

Heart hypertrophy
Increase in resting heart rate
Decrease in likelihood of heart disease
Increase in cardiac output
Increase in minute ventilation
Identify 3 effects of exercise on the lungs
Decrease in lung volume
Increase in minute ventilation
Increase strength of respiratory muscles

Which of the following are not long term effects of a 3 month training programme on the muscular system?
Increased rate of removal of lactic acid
Decreased speed of contraction
Decreased recovery rate
Helps with injury prevention
Increased strength of connective tissue (tendons and ligaments)
Which of the following are the short term effects of pre-season training on a players' heart?
