FiTour terms in Metabolic, Cardiovascular, and
Respiratory Responses to exercises Exam GRADED A.
Energy - answers Energy comes from carbohydrates, fats, and proteins. Energy
must be converted to Adenosine Triphosphate (ATP) be used by nerves, muscles,
and other cells.
Oxygen uptake - answers The rate at which oxygen is utilized during a specific level
of an activity.
Oxygen Deficit - answers The difference between the theoretical oxygen requirement
of a physical activity and the measured oxygen uptake.
steady state - answers The point during exercise at which oxygen uptake is
unchanging or changed very little.
Oxygen Debt or Excess Postexercise Oxygen Consumption (EPOC) - answers The
amount of oxygen used during recovery from work that exceeds the amount needed
for rest.
VO2max - answers The greatest rate of oxygen utilization attainable during heavy
work. Expressed in L-min-1 or ml-kg-1 -min-1
heart rate - answers The number of beats of the heart per minute
Stroke volume - answers The amount of blood pumped in one beat of the heart
cardiac output - answers The amount of blood circulated by the heart in one minute.
Formula expressed as. Heart Rate x stroke Volume =cardiac Output
Blood pressure - answers The pressure exerted by the blood on the vessel walls,
measured in milliliters of mercury by The sphygmomanometer.
pulmonary ventilation - answers The process of oxygenating the blood through the
lungs.
Lactate Threshold (Ventilation Threshold) - answers The point during a graded
exercise test at which the blood lactate concentration suddenly increases; a good
indicator of the highest sustainable work rate.
Effects of Endurance Training - answers Increase in # of Mitochondria ( the
powerhouse of Cells)
Decrease time that it takes to achieve steady state
Size of the ventricle of the heart increases, increasing the amount of blood that can
be pumped with one beat of the heart.
Increased VO2 max
