Exercise Prescription

Question 1

types of experiements
1. in vitro
2. in vivo
3. ex vivo

Answer 1

1. outside in an artificial environment
2. conducted in a living creature
3. intact bio unit outside of creature

Question 2

general PA recommendations
1. overview
2. ACSM guidelines for individuals with chronic health conditions and disabilities

Answer 2

1. recommendations from American College of Sport Med (ACSM) and Canadian Soc of Exercise Physiol (CSEP) for lifestyle habits such as sleep, diet, and exercise, >150 min of mod to vigorous PA and breaking up sitting with light PA such as standing; 2+ days of whole body strength. and balance for fall risk and older adults
2. similar to healthy, 150-300 min mod PA or 75-150 vigorous, 2+ days strength, if not able to do what you are able, something is better than nothing

Question 3

clinical exercise program
1. evaluating physical functioning and performance
2. clinical exercise programming

Answer 3

1. use exercise tolerance test for how well person can perform physically using tests that simulate tasks performed in daily life
2. use tests to determine capabilities and limitations; Bruce test is progressive exercise test by Dr. Robert Bruce to safely id physiological limits in individual with pathophysiology to prescribe near but sub maximal threshold activity to improve health without risk; no safe way to asses prior, patients often assigned rest which worsens disease progression

Question 4

exercise stress testing: contraindications

Answer 4

determine if benefit of answering clinical questions are greater than risk of test
1. absolute contraindications are serious events that could cause more harm immediately with exercise are not worth risk
2. relative contraindications are serious but are worth the risk since they are not immediately harmful

Question 5

prescribing exercise: adverse events

Answer 5

1. activity dependent due to poor form or overuse, solve with supervision, instruction, and training
2. disease dependent related to pathophysiology, solve with lowered intensity in line with disease specific testing

Question 6

measuring exercise intensity
1. RPE
2. ventilatory symptoms

Answer 6

1. Borg RPE using HR is linear and accurate (scale 6-20 since RHR is 30) but accessing monitor, drugs, and heart conditions make it hard to use it as measure
2. ventilatory symptoms using Borg Dyspnea scale comp exertion vs. ventilationis non linear relation, less accurate but more convenient, light intensity normal breathing can be sustained for 60+ mins, moderate can carry convo and sustained for 20-30 mins; vigorous fail talk test; high heavy breathing near maximal <10 mins

Question 7

terminology
1. exercise
2. PA
3. sedentary behaviour
4. physical fitness
5. physical function

Answer 7

1, planned, structured, and repetitive PA following FITT, vol, pattern, and progression
2. any movement above resting level
3. sitting or lying with little to no movement
4. ability to carry out daily tasks with E; cardioresp, strength and endurance, body comp, flexibility, and neuromotor control
5. Capacity to carry out daily tasks, reflect fitness and function, predict ability to live independently
