CSEP-CPT ExamCardiac Output - ANS-The amount of blood the heart pumps through the circulatory
system in a minute=HRxSV
Stroke Volume (SV) - ANS-The amount of blood pumped out of the heart with each
contraction.
Average cardiac output at rest and during exercise? - ANS-Rest: 4900 mL/min
Exercise: 22800-34200 mL/min
Average stroke volume during exercise and at rest? - ANS-Rest: 70 mL/b
Exercise: 120-190mL/b
Blood Pressure - ANS-Refers to the pressure blood exerts on walls of blood vessels,
and reflects efficiency of blood flow through the CV system
Diastolic blood pressure - ANS-the pressure remaining in the arteries when the left
ventricle of the heart is relaxed and refilling
Systolic blood pressure - ANS-the pressure created in the arteries when the left
ventricle contracts and forces blood out into circulation
Heart Rate and average values - ANS-number of heart beats/minute
- RHR average 60-80bpm
- higher RHR for women
- lower RHR with age
Normal Responses to short-term, light-mod Aerobic Exercise - ANS-CO: Increases
rapidly;
plateaus at steady
state within 2 min
SV: Increases rapidly;
plateaus at steady
state within 2 min
HR: Increases rapidly;
plateaus at steady
state within 2 min
SBP: Increases rapidly;
,plateaus at steady
state within 2 min
DBP: shows little or no change
Canadian's Physical Activity Guidelines - ANS-15% adults meet recommended 150mins
MVPA/week7% youth meet recommended 60mins MVPA/day with 3 days being
vigorous
Characteristics of Type 2A Muscle Fibers - ANS-Fast oxidative (FO) fibers have fast
contractions and primarily use aerobic respiration, but because they may switch to
anaerobic respiration (glycolysis), can fatigue more quickly than SO fibers.
Characteristics of Type 2B (2x) Muscle Fibers - ANS-Fast glycolytic (FG) fibers have
fast contractions and primarily use anaerobic glycolysis. The FG fibers fatigue more
quickly than the others[3].
Characteristics of Type 1 Muscle Fibers - ANS-Slow oxidative (SO) fibers contract
relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP. They
produce low power contractions over long periods and are slow to fatigue.
Antagonist muscles - ANS-opposing muscles that relax and lengthen
Antagonistic pairs of muscles - ANS-When one contracts the other relaxes (ex: biceps
and triceps)
Agonist Muscles - ANS-primary movers, that work with synergist (helper muscles) to
generate force required for movement-
Stabilizer muscles - ANS-stabilize joint so movement can occur at another joint
Global Stabilizers - ANS-stabilize trunk/"core" to create more solid foundation for
movement
Cardio respiratory Response to Acute Exercise - ANS-HR anticipatory response - HR
increases at the beginning of exercise
increased cardiac output
redistribution of blood to working muscles and heart
increased blood pressure
vasoconstriction to smooth muscles
vasodilation to skeletal muscles
, Cardio Respiratory Response to Chronic Exercise - ANS-- decrease in RHR
- decrease in SV at rest
- improved circulation
- BP decrease by up to 10mmHg
- increased blood volume
Aerobic energy systems - ANS-- Anaerobic Alactic
- Anaerobic Lactic
- Aerobic
What is the fuel of the Anaerobic (Alactic) energy system? By products? - ANS-Fuel:
ATP and CPDuration : 0-15 secs
By products: ADP, Cr, Pi
(creatine phosphate + inorangeic [hosphate
Activity: 100m sprint, jumping or lifting
What is the fuel of the Anaerobic (Lactic) energy system? By products? - ANS-CHO
incomplete breakdown
15-20s
Lactic acid, 2ATP/mol CHO
200m power, 800m endurance, resistance training
What is the fuel of the Aerobic energy system? By products? - ANS-CHO, Fats, <5%
protein and complete breakdown
120-several hours
CO2, water, heat, 36ATP
Distance running, 1500m (power)
Marathon (endurance or capacity
Aerobic Energy System Activity Examples? Timeframe? - ANS-Time Frame: 120s -
several hours
Activity Examples: distance running, 1500m (power), marathon (endurance or capacity)
Aerobic Energy System fuels? By Products? - ANS-Fuels: CHO, fats, protein (<5%)
"complete breakdown"
By-Products: CO2, water, heat, 36 ATP/mol CHO (net)
Most Valid and Direct measure of VO2 Max - ANS-Aerobic gold standard test is
considered to be a direct measurement of a client's maximal oxygen consumption (VO2
