Claudication - answer- pain in the leg is induced by exercise, usually
because of an artery obstruction.
What is the par-q? Limitation? - answer- a minimal standard for entry
into moderate-intensity exercise programs. Allows individuals to
gauge their own medical readiness to participate . Does not screen
well for those at low to moderate risk.
What is a pre-participation screening questionnaire? - answer- also
useful for clients to assess their health readiness. More comprehensive
and recognizes signs and symptoms of cvd and other risk-factor
thresholds.
Creatine phosphate system - answer- small amounts of cp are stored
within each cell. Simple one-to-one trade off that allows for the rapid
production of atp. Only for use during short bouts of exercise. Less that
10 seconds.
Anaerobic glycolysis - answer- no oxygen required. Next most
immediate energy source. Break down carbs (glucose or glycogen) into
pyruvate. Used during medium-duration exercise. No more than about 90
seconds.
,Aerobic glycolysis (oxidative system) - answer- oxygen dependent. As
exercise intensity decreases allowing for longer duration activities, use
of the oxidative system increases. (krebs cycle and etc). Produce atp in
the mitochondria of the cell--requires oxygen. Lasts longer than 1-2
minutes.
What is vo2? - answer- the volume of oxygen the body consumes. Vo2
max is the highest volume of oxygen the body can consume.
Define stroke volume - answer- the volume of blood the heart ejects
with each beat.
How does sv increase with workload? - answer- similar to hr, it
increases as workload increases but only up to ~40% to 60% of vo2max.
The percentages can be decreases in sedentary individuals and increased
with training.
What happens to resting hr as stroke volume increases? - answer- it
decreases, as more blood being pumped per beat allows the heart to beat
less often.
What is cardiac output? - answer- a measure of blood pumped per
minute. The product of stroke volume and heart rate.
What does diastolic blood pressure do during exercise? - answer-
remains stable or decreases slightly.
What is rate pressure product? - answer- serves as an estimate of
myocardial oxygen demand. Product of hr and systolic bp. Hr x sbp
What is the fick equation used to determine vo2 max? - answer-
vo2max = hrmax x svmax x a-vo2 difference max (arteriovenous oxygen
difference)
,What is the gold standard to measure cardiorespiratory fitness? -
answer- vo2 max during open circuit spirometry.
How does a submaximal exercise test work? - answer- it estimates
vo2 max from the hr response to submaximal single stage or graded
exercise.
Physical activity - answer- any bodily movement produced by
contracting skeletal muscles, with an increase in energy expenditure.
Exercise - answer- planned, purposeful, repetitive
Physical fitness - answer- attributes or characteristics that individuals
have achieved that related to their ability to perform physical activity
3 metabolic pathways the body uses to creates atp - answer- 1. Creatine
phosphate
2. Anaerobic glycolysis
3. 0xidative system
Absolute oxygen consumption vs. Relative oxygen consumption -
answer- absolute is the raw volume of o2 consumed by the body.
Relative is the volume of o2 consumed relative to body weight. Useful
to compare fitness levels between individuals.
What is one of the largest components of pa-related energy
expenditure? - answer- occupational physical ativity
5 health related physical fitness components - answer- cardiorespiratory
endurance, body composition, muscular strength, muscular endurance,
and flexibility
6 skill (performance) related physical fitness components - answer-
agility, coordination, balance, power, reaction time, and speed
Cardiorespiratory endurance - answer- ability of circulatory system and
respiratory system to supply o2 during sustained physical activity
, Body composition - answer- relative amounts of muscle, fat, bone, and
other vital parts of the body
Muscular strength - answer- ability of muscle to exert force
Muscular endurance - answer- ability of muscle to continue to perform
without fatigue
Flexibility - answer- rom at a joint. As per the skeletal muscles and not
any external forces.
