Aerobic
|
Means "with air" -relates to the energy process that occurs in the presence of adequate oxygen
|
|
|
Cardiovascular Fitness
|
This is a type of dynamic exercise involving large muscles during a moderate to high intensity exercise of a prolonged period
|
|
|
Cardiovascular Fitness reflects...
|
the lung taking in air and transporting it to the blood
the heart pumps the oxygenated blood to the tissues the blood vessels carry the blood the blood is saturated with oxygen the muscles extract the oxygen and utilize it |
|
|
Oxygen Consumption VO2MAX
|
V=volume of oxygen per a min
O2= Oxygen Max= the maximal rate at which the oxygen can be consumed during exercise or the maximal rate at which oxygen can be UPTAKE,DISTRIBUTED,UTILIZED by the body during PA. |
|
|
UPTAKE,DISTRIBUTION,UTLIZATION
|
the lungs take in the oxygen, transports it to the blood, to the tissues, skeletal muscle utilizes through the workout
|
|
|
Rick Equation
|
CO = VO2( A-VO2)
VO2= CO / (A-VO2) |
|
|
MAX O2 other names
|
VO2 max, peak aerobic power, maximal aerobic power, maximum voluntary oxxygen consumption, cardio-respiratory aerobic capacity, maximal cardio-respiratory fitness, maximal functional aerobic capacity
|
|
|
Best way of measuring VO2max
|
Direct measurment using a metabolic cart
|
|
|
Abosolute, Relative, and METS
units of VO2max |
Absolute = L/min
Relative = ml/kg/min BODY WEIGHT ml/kg of FFM/min relative to FFM 1 Met = 3.5 ml/kg/min MET= Metabolic Equivalents metabolic equivalent rate |
|
|
Validity
Reliability |
Valid- the degree of which the test measures what its suppose to measure ... greater than 0.90
Reliability- the degree of consistent repeated results..greater than 0.80 |
|
|
Percentages of Physical activity in the world
Obese percentage Sedentary percent REPS for young and older adults |
60% world pop meets the PA standard recommendation
50% of US adults meet it 25% US adults no PA 30% adults obese Younger adults 18-24 8-12 reps Older than 65 10-15 reps older = flexibility and balance |
|
|
The order of tests before the activity
|
-Resting body measurements = height,weight,blood pressure, heart rate
-Body composition %body fat -cardiovascular endurance -muscloskeletal endurance -balance and flexibility |
|
|
Vo2 max range
|
15 = sedentary with disease
75 = young endurance runner women about 10-20% lower than men or 15-30% even when body mass is taken into account due to men having larger lungs, oxygen capacity, differences enzymatic capabilites |
|
|
Weight vs. cardiorespirtory fitness
|
they may loose weight which changes the VO2max to higher but not a true improvement in fitness
|
|
|
1 L = 1000 ml
|
convert absolute to relative
|
|
|
1 MET =
|
resting metabolic rate 3.5ml/kg/min
it is a relative term due to the weight is included |
|
|
VO2 max depends on
|
Cardiac output = stroke volume, peripheral resistance, heart rate
Muscle mass Muscle fiber type -Hemoglobins -Oxygen Extraction = muscle mitochondrial density and oxidative ezymes - Muscle blood flow - capillary density |
|
|
Factors affecting VO2 max
|
Age - Child<Adult
- Older adult< young adult Hereditary - estimated 25-40% aerobic capacity has a genetic component Mode of the exercise = related to the amount of muscle utilized treadmill=bench stepping>cycling>arm ergometer -Think about the specificity of the mode -Body size and composition -Training status -Amplitude -Temperature |
|
|
Criteria of VO2max
|
VO2 does not increase by more than 150ml/min with increase in workload
-Lactate concentration increase 8mmol/L - RER- greater than 1.5 -RPE- increase 17 -HR plateaus |
|
|
VO2max can be assesed by using MAXIMAL V2. SUBMAXIMAL
|
maximal - clinical, diagnostic
may be directly measured using metabolic cart or may be estimated by time a treadmill SUBMAXIMAL- provide heart rate and blood pressure response to different intensities, estimated by using HR response, not diagnostic, less cost and time consuming Should i use max or submax Client and Setting, reasons for administering the test, equipment and personalell |
