Why do muscles get warmer when you exercise?
Because muscle contractions release heat as a byproduct of metabolism (especially ATP breakdown).
What is the maximum heart rate of a 67 year old?
153bpm (beats per minute)
The amount of air breathed in and out per minute is measured in?
(L/Min) - Litres per minute (Ventilation)
What is the acute response to the body's increase in muscle temperature?
Sweating
At what state does the oxygen supply exceed the demand?
EPOC - Excess Post-Exercise Oxygen Consumption
What is the muscle found on the front of the lower leg between the knee and the ankle?
Tibialis Anterior
What role does vasodilation play in acute cardiovascular response during exercise?
Blood vessels widen in active muscles, increasing blood flow and oxygen delivery while helping remove waste like CO₂ and lactate.
What is the increased tidal volume definition and what is the equation?
The total volume of air moved in and out of the lungs per breath (L/Breath)
The muscles use/extract more oxygen from the blood during exercise because of...
increased demand for energy. (ATP)
Which stage of exercise involves a plateau?
Steady State

Fast Twitch Fibre
Blood is ejected through the contraction phase of the heart cycle - What is this phase called?
Systolic Phase
__ = RR x TV - What is missing?
V - Ventilation
The human body has 3 fuel types for exercise... they are?
PC - (Phosphate Creatine)
Glycogen - (Glucose)
Triglycerides - (Fats)
