What are the immediate short term responses?
Heart rate, Breathing, Skin colour, Perspiration Feeling
Stroke Volume, Size of Heart, Breathing
Size of Heart, Heart Rate, Perspiration
Heart Rate, Skin Colour, Stroke Volume
Why does the heart rate increase? (There is more then ONE correct answer)
Exercise places an increased demand on the cardiovascular system - altering the heart rate.
To perform as efficiently as possible the cardiovascular system must regulate these changes and meet the bodies increasing demands
Oxygen demand by the muscles increases sharply.
Heart rate increases to make you perform better
Blood is also responsible for the removal of waste products, like carbon dioxide. If the heart pumps more blood, waste products are removed quicker.
Our breathing rate increases and you start to breathe heavily, this happens because
More blood gets circulated around the body
We have started to perform a physical activity
To break down Lactic Acid and replenish energy supplies.
Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
Skin coloured during exercise is called
Cholesterol
Vaccimulgence
Vasodilation
Palpitations
The burning sensation you feel during and shortly after exercise is largely due to
Proteins
Lactic Acid
Hormones
Acids
Immediate effects of Physical Activity include:
Increased Cardiac Output
Increased Stroke Volume
Increased Ateriovenous O2 Difference
Muscle Hypertrophy
Increased Stroke Volume occurs as a result of:
More venous blood is being returned to the heart
Increased blood pressure
Selective redistribution of blood
All of the above
Selective Redistribution of Blood occurs when:
To prevent the overheating of muscle tissue
Because of the increased need for oxygen and removal of Carbon Dioxide
Arteries dilate or constrict selectively to direct blood flow from non working muscles
Cardiac Output increases
Long Term Adaptations include:
More efficient Respiratory Rate
Greater Aerobic Capacity
Decrease in cardiac Output
Muscle Hypertrophy
Increase in Blood Volume
Decreased Resting Heart Rate
Increased Resting Heart rate
Decreased Stroke Volume
Greater Aerobic Capacity
Faster recovery from exercise
Improved Posture
Decreased oxygen extraction

Which of these defines the word 'predominantly'?
Taking place by itself / independently

Present as the strongest or main element
More important than anything else
Which of these defines the word 'replenish'?
Return to a normal state of mind or strength after a period of exertion
Resume (an activity) after an interruption
Use up (resources or reserves) completely
Restore (a stock or supply) to a former level or condition
Why does the body require the three different energy systems?
