Exercise Physiology - Effects of Exercise and Energy Systems

The amount of air entering and leaving the lungs with each breath.

• tidal volume

• total lung capacity

• residual volume

• inspiratory reserve volume

The greatest amount of air that can be expired after a maximal inspiration.

• tidal volume

• total lung capacity

• vital capacity

• residual volume

The amount of air remaining in the lungs after a maximal expiration.

• tidal volume

• total lung capacity

• vital capacity

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
