Exercuse Physiology

Question 1

Acute responses of fitness on the cardiovascular system

Answer 1

• heart rate = number of times the heart beats per minute
• stroke volume = the volume of blood pumped per beat
• cardiac output = amount of blood pumped around the body per minute
• systolic blood pressure = the pressure placed upon the arteries during contraction of the heart
• diastolic blood pressure = the pressure placed upon the arteries during relaxation of the heart

Question 2

Acute responses of fitness on the respiratory system

Answer 2

• breathing rate = the amount of times we breathe in a minute
• tidal volume = the volume of air inhaled each breathe
• minute ventilation = the volume of air inhaled we inhale
• gas exchange rate = the rate at which diffusion occurs to exchange oxygen and carbon dioxide

Question 3

Food sources and their role in energy production

Answer 3

Carbohydrates - digest very quickly so can be used to rebuild ATP fast, therefore they are a primary source of food
Fats - high and long lasting energy source, slow to digest and to be converted into a usable form of energy, used hen carbohydrates are depleted
Proteins - primary function of proteins is to build and repair tissues - very important in recovery from intense training

Question 4

Aerobic vs anaerobic

Answer 4

Anaerobic is fats working, it requires oxygen, fuel source is carbohydrates and the byproduct is lactic acid.
Aerobic is the opposite
