5.1 Aerobic Exercise Flashcards
What is the following a definition of?
- A measure of the body’s capacity to use oxygen
- maximum amount of oxygen consumed per minute when the individual has reached maximum effort
- expressed as mL/kg per minute
- dependent on the transport of oxygen
- INDICATOR of physical fitness
Maximum Oxygen Consumption (VO2 Max)
What is the ability of an isolated muscle group to perform repeated contractions over a period of time
Muscular Endurdance
What is the ability to perform large muscle dynamic exercise
Cardiovascular Endurance
What is the enhancement of the energy utilization of the muscle by means of an exercise program
- increased levels of oxidative enzymes in muscles
- increased mitochondrial density and size
- increase muscle fiber capillary supply
Aerobic Exercise Training
What is the cardiovascular system and the muscles used to adapt to the training stimulus over time
Adaptation
Which system has the following characteristics?
- PC and ATP are stored in the muscle cell
- PC is the chemical fuel source
- No oxygen is required (anaerobic)
- When muscle is rested, the supply of ATP-PC is replenished
- max capacity of the system is small
- max power of the system is great
- system provides energy for short, quick bursts of activity
- major source of energy during the first 30 seconds of intense exercise
Phosphagen or ATP-PC System
Which system has the following characteristics?
- glycogen (glucose) is the fuel source (glycolysis)
- no oxygen is required (anaerobic)
- ATP is resynthesized in the muscle cell
- Lactic acid is produced
- max capacity of the system is intermediate
- max power of the system is intermediate
- provides energy for activity of moderate intensity and short duratin
- major source of energy from the 30th or 90th second of exercise
Anaerobic Glycolytic System
Which system has the following characteristics?
- Glycogen, fats, & proteins are fuel sources & are utilized relative to their availability and the intensity of the exercise
- Oxygen is required (aerobic)
- ATP is resynthesized in the mitochonidria of the muscle cell; ability to metabolize oxygen and other substrates is related to the number & conc. of the mitochondria and cells
- max capacity of the system is great
- max power of the system is small
- predominates over the other energy systems after the second minute of exercise
Aerobic System
What is the oxygen consumed (milliliters) per kilogram of body weight per minute (mL/kg)
Metabolic Equivalent (MET)
What age group are field tests limited to?
Young persons are middle aged
Which exercise test is this?
- Warm-up consisting of static stretching and walking on the treadmill; find the pace the client can walk vigorously one mile
- have client walk at established pace for one mile; record time
- Palpate pulse for 10 sec
- Multiply pulse by 6
- Plug results into VO2 formula below
Rockport
Which exercise test is this?
- Pt should be sitting at start
- Read off of prompt exactly
- Patient can take as many standing rests as needed, record number of rests taken and total rest time
- May use assistive device
- Don’t walk in front or next to pt
6 Min Walk Test
What type of exercise test is this?
- Record pt’s body weight and resting HR
- Start metronome with a frequency of 45 beats per minute
- Start stopwatch and have your patient step up on box
- Record your patient’s heart rate each minute for total of 6 minutes
Harvard Stop Test
What is this test called?
Evaluates cardiovascular functional capacity as a means of clearing individuals for strenuous work or exercise programs
Stress Testing
What type of training method is this?
Sub-max energy requirement, sustained throughout the training period
Continuous Training
