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
coordination correct answers ability to use the senses together with body parts to perform tasks smoothly and accurately balance correct answers maintenance of equilibrium while stationary OR moving
reaction time correct answers time elapsed between stimulation and the beginning of the reaction
to said stimulus
speed correct answers ability to perform a movement within a short period of time
ACSM's weekly/daily physical activity recommendations correct answers 150 minutes Moderate PA per week (30 min or more most days of the week), 75 minutes of vigorous intensity
Can most sedentary individuals safely begin a low-to moderate intensity PA Program without the
need for baseline testing or medical clearance? correct answers Yes indeed
Most common musculoskeletal injuries occur in what area of the body? correct answers lower body- particularly the knee or foot
Who is most at risk for sudden cardiac death? correct answers Sedentary individuals performing infrequent exercise
Light PA is defined as correct answers <3 MET's
Moderate PA is defined as correct answers 3 to <6 MET's
Vigorous PA is defined as correct answers >/=6 MET's
What is 1 MET? Why do we use METs? correct answers 1 MET = the relative oxygen consumption at rest. or, 3.5 mL per kg per minute. It is an easy way for the general public to gauge their exercise intensity. Also used to calculate energy expenditure over time.
What is a kilocalorie? what is it also known as? correct answers AKA: Calorie. estimate of energy cost that can be directly related to physical activity and exercise. Weight gain, loss and maintenance can be estimated remembering that 3,500kcal =1 lb of fat.
Is the ACSM's weekly recommended PA sufficient to prevent weight gain in the typical american lifestyle? correct answers Hell na! They must go beyond these recommendations.
Two types of pre-participation self-guided screenings correct answers 1. PAR-Q (physical Activity Readiness Questionnaire)
2.Fitness Facility Pre-participation screening questionnaire
What is the PAR-Q? Limitation? correct answers 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.
