Fast twitch fibres are associated with explosive events.
Which feature is not associated with fast twitch fibres.
They contract with more force.
They tire easily
They are suited to activities requiring strength and power
They do not tire easily
Anaerobic respiration creates which waste product?
Oxygen
Lactic acid
Carbon dioxide
Water
Lactic acid is turned into carbon dioxide and water when oxygen supply is resumed.
Glycogen is the main form of carbohydrate storage in the body. It is stored in the following areas of the body, except?
Lungs
Liver
Muscles
During vigorous exercise lactic acid is created. Lactic acid is a waste product and is a mild poison.
The following are short term effects of exercise, except?
Breathing rate increases
Cardiac output increases
Blood pressure lowers
Stroke volume increases
Fatigue is a feeling of extreme physical or mental tiredness. When a muscle gets so tired that they can no longer continue to work properly. Which of these is not a sign of fatigue?
Deep breathing
Lower level of concentration
Increased pulse
Red skin
An oxygen debt is when the muscles are starved of oxygen. The body recovers by carrying out the following functions, except?
Increase the respiratory rate
Increase the depth of breathing
Continuing the activity
Stopping the activity
Which of the following facts is false in relation to muscle cramp.
It is a voluntary contraction
A muscle is locked in contraction
It is a result of intense exercise
The muscle is in spasm
The circulatory system consists of the heart, blood and blood vessels working together to supply oxygen to the working muscles and removing unwanted carbon dioxide.
The upper chambers of the heart are called the ventricles.
The right side of the heart is thicker as it transports oxygenated blood to the working muscles of the body.
The pulmonary circuit involves taking deoxygenated blood to the lungs and returning oxygenated blood to the heart.
Arteries always carry blood away from the heart.
Arteries always carry oxygenated blood.
White blood cells contain a substance known as haemoglobin.
Which of these functions is not a role of the circulatory system.
Temperature regulation
Energy production
Protection
Transportation
Which of these answers is a waste product and removed by the circulatory system.
Heat
Hormones
Glucose
Arteries have thin outer walls and a thin layer of muscle.
Which blood vessel is only one cell thick?
Veins
Arteries
Capillaries
Arteries contain valves.
Which defintion relates to stroke volume?
One contraction and relaxation of the heart
The amount of blood pumped out of the left ventricle per minute
The number of times the heart beats in a minute
The amount of blood pumped out of the left ventricle per beat
Which artery is located in the groin?
Radial
Femoral
Temporal
Carotid
The cardio vascular systems involves the working of the following organs.
Heart and Liver
Lungs and Kidneys
Liver and Lungs
Heart and Lungs
Maximum heart rate is calculated using which formula?
220 plus age
220 multiplied age
220 divided age
220 minus age
The aerobic training zone is 80 - 90% maximum heart rate
The training zone is the range of the heart rate within which a specified training effect will take place.
Which definition relates to the threshold of training.
The maximum heart rate needed to have a training effect
Training at 60-80% MHR
Training above 90% MHR
The minimum heart rate needed to have a training effect
