questions with answers
Physical Activity - CORRECT ANSWERS ✔✔Any bodily movement produced
by contracting skeletal muscles, with an increase in energy expenditure.
Exercise - CORRECT ANSWERS ✔✔Planned, purposeful, repetitive
Physical Fitness - CORRECT ANSWERS ✔✔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 - CORRECT ANSWERS
✔✔1. Creatine Phosphate
2. anaerobic glycolysis
3. 0xidative system
Claudication - CORRECT ANSWERS ✔✔pain in the leg is induced by exercise,
usually because of an artery obstruction.
Creatine Phosphate system - CORRECT ANSWERS ✔✔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 - CORRECT ANSWERS ✔✔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) - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔The volume of oxygen the body
consumes. VO2 max is the highest volume of oxygen the body can consume.
Define Stroke Volume - CORRECT ANSWERS ✔✔the volume of blood the
heart ejects with each beat.
How does SV increase with workload? - CORRECT ANSWERS ✔✔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? - CORRECT
ANSWERS ✔✔it decreases, as more blood being pumped per beat allows the
heart to beat less often.
,What is cardiac output? - CORRECT ANSWERS ✔✔a measure of blood
pumped per minute. The product of stroke volume and heart rate.
What does Diastolic Blood pressure do during exercise? - CORRECT
ANSWERS ✔✔Remains stable or decreases slightly.
What is rate pressure product? - CORRECT ANSWERS ✔✔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? - CORRECT
ANSWERS ✔✔VO2max = HRmax X SVmax X a-VO2 difference max
(arteriovenous oxygen difference)
What is the gold standard to measure Cardiorespiratory fitness? - CORRECT
ANSWERS ✔✔VO2 max during open circuit spirometry.
How does a submaximal exercise test work? - CORRECT ANSWERS ✔✔It
estimates VO2 max from the HR response to submaximal single stage or graded
exercise.
absolute oxygen consumption vs. relative oxygen consumption - CORRECT
ANSWERS ✔✔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? -
CORRECT ANSWERS ✔✔Occupational Physical Ativity
5 Health related physical fitness components - CORRECT ANSWERS
✔✔Cardiorespiratory endurance, body composition, muscular strength,
muscular endurance, and flexibility
6 Skill (performance) related physical fitness components - CORRECT
ANSWERS ✔✔Agility, coordination, balance, power, reaction time, and speed
cardiorespiratory endurance - CORRECT ANSWERS ✔✔ability of circulatory
system and respiratory system to supply o2 during sustained physical activity
Body composition - CORRECT ANSWERS ✔✔relative amounts of muscle, fat,
bone, and other vital parts of the body
Muscular strength - CORRECT ANSWERS ✔✔Ability of muscle to exert force
muscular endurance - CORRECT ANSWERS ✔✔ability of muscle to continue
to perform without fatigue
flexibility - CORRECT ANSWERS ✔✔ROM at a joint. as per the skeletal
muscles and not any external forces.
Agility - CORRECT ANSWERS ✔✔ability to change position of the body in
space with speed and accuracy
