CSEP CEP CORE MAIN EXAMINATION SET
QUESTIONS AND ANSWERS SURE A+
✔✔What is the normal response to submaximal exercise? - ✔✔Oxygen demand and
production of waste products increases and prompts the body to increase cardiac
output (Q) which is the product of stroke volume X HR
Q will increase from 5 L/min at rest to about 20-30 /min during submaximal exercise.
Heart rate - as oxygen uptake increases in response to increased demands from the
working tissues, the heart rate increases
Stroke Volume - as oxygen demands from the working tissues increase, the stroke
volume increases linearly up to an intensity of 50% of VO2 max at which point the HR
continues to rise to meet the increased O2 demands
Blood pressure - systolic BP increases as the body attempts to force blood through the
active contracting muscles (increased vascular resistance from the contraction of the
muscles)
✔✔What is a abnormal response to submaximal exercise? - ✔✔Heart rate that does not
increase
Systolic Blood pressure that does not increase
, ✔✔What is the response of the cardiorespiratory system to acute exercise? (A single
bout) - ✔✔Oxygen demand and production of waste products increases and prompts
the body to increase cardiac output (Q) which is the product of stroke volume X HR
Q will increase from 5 L/min at rest to about 20-30 /min during submaximal exercise.

Blood pressure - systolic BP increases as the body attempts to force blood through the
active contracting muscles (increased vascular resistance from the contraction of the
muscles)
✔✔What is the response of the cardiorespiratory system to chronic exercise? (Ongoing
consistent exercise training) - ✔✔Longer term physiological adaptations:
> cardiac output
>stroke volume
>blood volume
>hematocrit (higher ratio of red blood cells which carry O2 to total volume of blood)
>heart volume
>size/number of mitochondria
>mitochondrial enzymatic activity
>capillarization
>in fat oxidation enzyme capacity
>blood supply/vascularization to the heart muscle
>left ventricular volume
>ventricular wall thickness (hypertrophy of the heart muscle)
< peripheral resistance (decreased resting BP)
✔✔What are the 3 energy systems? - ✔✔Aerobic Alactic (ATP-PCr) system
Anaerobic Lactic (CHO) system
Aerobic (CHO, Fats, Proteins <5%) system
✔✔Anaerobic Alactic energy system - ✔✔- AKA: High energy phosphate system
- dominant source of energy for the high rate of energy supply needed at the onset of
any movement
-provides immediate energy
-does not require energy
-does not produce lactic acid
-does not require oxygen
-uses ATP already stored in the muscle and converts Cp - phosphocreatine into usable
ATP.
