Chapter 8 Cardiorespiratory Final Flashcards
(39 cards)
What is CARDIOrespiratory training PROGRAMS that SYSTEMATICALLY PROGRESS clients THROUGH various STAGES to achieve optimal levels of physiologic, physical, and performance adaptations by placing stress on the cardiorespiratory system.
INTEGRATED cardiorespiratory training
Studies show that cardio fitness level is important because…
It is ONE of the most reliable PREDICTORS of PREMATURE DEATH.
Describe 3 aspects of the movements in the cardio portion of the Warm-Up Phase.
How long does the cardio portion of the warm up last?
In what part of the warm up should the cardio portion occur?
- Uses WHOLE-BODY,
- Uses DYNAMIC movements
- Well BELOW the ANTICIPATED training INTENSITY threshold for conditioning
- Typically lasts between 5-10 minutes
- Should occur after the flexibility portion
List 8 mental and physical changes that occur from warming up?
INCREASES:
- (incr. heart rate) BLOOD flow
- (incr. respiratory rate) OXYGEN exchange capacity
- Rate of muscle CONTRACTION
- Efficiency of ANTAGONIST muscle contraction and relaxation
- METABOLIC rate
- FLEXIBILITY
- PSYCHOLOGICALLY PREPARES for high training intensities.
- Incr. tissue TEMPERATURE
List the 3 components of the warm-up for the: -STABILIZATION level, -STRENGTH level, -POWER level of the OPT model.
- Self Myofascial Release
- Stretching:
a. Static (stabilization)
b. Active-isolated (strength)
c. Dynamic (power) - Cardio
What is Integrated Cardiorespiratory Training?
Cardiorespiratory training programs that systematically progresses clients through various stages to achieve optimal levels of physiologic, physical, and performance adaptations by placing stress on the cardiorespiratory system.
How long should a person spend on each muscle during Active-Isolated Stretching (Strength Phase Warm-Up)?
How many reps?
- 1-2s
- 5-10 reps for each muscle
How many reps should be performed for each muscle during Dynamic Stretching (Power Phase Warm-Up)?
How can it be performed where it can eliminate the need for CRE Warm-Up?
- 10 repetitions of each side
- Can be performed in circuit format, one after another, which eliminates CRE!
What is a sufficient amount of time for the Cool-Down Phase?
List 3 suggested activities for the cool down phase in the correct order.
5-10 minutes
- Cardio
- SMFR
- Static stretching
What are 3 physiological changes to blood during exercise?
During intense, vigorous exercise:
- CIRCULATION of blood INCR. up to as much as 80-85% of cardiac output (at rest, usually only 15-20% of circulating blood reaches cardiac muscle)
- BLOOD is SHUNTED AWAY FROM major ORGANS (kidneys, liver, stomach and intestines) and REDIRECTED TO SKIN to promote HEAT LOSS
- BLOOD PLASMA VOLUME also DECR. with the onset of exercise and as exercise continues, INCR. BLOOD PRESSURE forces water from the vascular compartment to the interstitial space (during prolonged, plasma volume can decrease as much as 10-20%)
Define the concept of Maximal Oxygen Consumption (VO2max)?
What is it more mathematically?
The highest rate of oxygen transport and utilization achieved at maximal physical exertion.
(Maximal volume of oxygen per kilogram of body weight per minute)
Define Oxygen Uptake Reserve (VO2R)?
The difference between resting and maximal or peak oxygen consumption
Higher than __% of VO2max is generally required for IMPROVEMENT in overall fitness and conditioning.
60%, hard intensity, a level where breathlessness is experienced.
How is intensity chosen using the PEAK VO2 method?
What is the general opinion of this method?
- Have clients exercise at a percentage of their VO2max. (maximal volume of oxygen per kilogram of body weight per minute)
- Traditional gold standard for measuring cardiorespiratory fitness
- Difficult to measure because requires client to perform cardio at maximal effort with sophisticated equipment to monitor ventilation response (O2 consumed and CO2 expire)
If moderate intensity of cardiorespiratory fitness is desired, what VO2max percentage should a person strive towards.
Less than 60% of VO2max
What is the VO2 Reserve Method?
What is the opinion of this method?
What is its calculation?
What is the recommended desired intensity for this method?
- A method of identifying and monitoring Cardiorespiratory exercise
- Preferred method according to the American College of Sports Medicine
- Calculation of Target VO2Reserve =
[(VO2max - VO2rest) x intensity desired] + VO2rest
Where… - VO2max can be estimated or directly measured
- VO2 rest (usually predicted and estimated) = 1 MET or 3.5mL O2 x kg-1 x min-1)
- Intensity Desired between 50% - 85% of VO2R, or 40% - 85% for deconditioned people
What is the Peak Metabolic Equivalent Method (MET)?
Give an example.
What is an MET mathematically?
What is the average MET?
- Used to describe the ENERGY COST of physical activity AS MULTIPLES of RESTING METABOLIC RATE
- Example: individual with a MET of 4 (slow-paced jogging) would require 4 times the energy than that of a person at rest
- One metabolic equivalent or MET is equal to 3.5mL O2 x kg-1 x min-1 or the equivalent of the average resting metabolic rate (RMR) for adults
What is the Peak Maximal Heart Rate Method?
What is this opinion of this method?
Formula most commonly used to determine someone’s maximum heart rate
HRmax = (220 - age)
Should never be used as an absolute. (results can be + or _ 12 beats per minute off)
What is the HR Reserve Method (HRR)?
What’s another name for it?
What is the calculation used?
- Karvonen Method
- Method to establish target heart rate when the desired training intensity is known.
- Its based on the difference between the client’s predicted maximal heart rate and their resting heart rate (selecting THR [target heart rate] based on a given % of O2 consumption)
- Calculation:
THR = [(HRmax - HRrest) x desired intensity + HRrest
Example: 25yr old client with a desired training intensity of 85% of HRmax, with resting HR of 40bpm 220-25 = 195 HRmax THR = [(195 - 40) x 0.85) + 40 THR = [155 x 0.85] + 40 THR = [132] + 40 THR = 172 bpm
What is used to EXPRESS HOW HARD a client FEELS they are working (subjectively rates perceived difficulty) during exercise?
How is it determined?
What is the range of the scale?
- BORG scale, or Ratings of Perceived Exertion Method (RPE).
- Based off OVERALL physical sensations a person experiences during physical activity (Increase in heart rate, respiration rate, sweating, overall muscle fatigue…not just isolated areas in the body)
- Scale:
- 6 = No Exertion At All
- 20 = Max Exertion
tip A high correlation exists between a person’s perceived exertion rating times 10 and the actual heart rate during physical activity; so a person’s exertion rating may provide a fairly good estimate of the actual heart rate during activity. For example, if a person’s rating of perceived exertion (RPE) is 12, then 12 x 10 = 120; so the heart rate should be approximately 120 beats per minute.
What is the Ventilatory Threshold (Tvent)?
The point during graded exercise in which VENTILATION INCR. DISPROPORTIONATELY TO OXYGEN UPTAKE, (your breathing increases but your not getting enough oxygen) signifying a switch from predominately AEROBIC energy production (slow twitch muscle fibers) to ANAEROBIC energy production (fast twitch muscle fibers).
“Most of your training should be done below it; a modest amount right at it; and a small but consistent amount above it.”
What is the recommended intensity (low, moderate or vigorous) one should do aerobic activity at if they exercise at least 5 days per week?
What should their Vo2R range be?
What should their HRmax range be at?
How many minutes per week?
Give an example.
- Moderate intensity
- Vo2R: 40% to < 60%
- HRmax: 55-70%
- 150 min every week (30 minutes 5 x wk)
- Example: Brisk Walking
What is the recommended intensity (low, moderate or vigorous) one should do aerobic activity at if they exercise at least 3 days per week?
What should their Vo2R range be?
What should their HRmax range be at?
How many minutes per week?
Give an example.
Vigorous intensity
- Vo2R >60%
- HRmax: >70%
- 75 min every week (25 minutes 3 x week)
- Example: Running or Jogging
What are the three types of criteria that must be met for an activity or exercise to be considered “aerobic” exercise? Give examples.
- Rhythmic in Nature
- Use Large Muscle Groups
- Continuous in Nature
Examples:
- Running or Jogging
- Walking
- Exercising on Cardio Equipment
- Swimming
- Cycling
