500-1,000 met/mins/wk or more

7,000
type
A wide variety of aerobic exercises can be undertaken.
Types of Cardio (A-D)
A: endurance (walking); for all B: Vigorous (all active); jogging, running C: Endurance + skill ; adults with acquired skill - swimming, etc. D. Rec sports: adults with reg. exercise; basketball
general recommendation
Adults should get at least 150 minutes of moderate-intensity exercise per week, 75 minutes of vigorous intensity exercise or a combination of the two. This should be accumulated in bouts of at least 10 minutes with activity occurring on most days of the week.
aerobic exercise
Continuous exercise utilizing large muscle groups (i.e. legs/back). training stresses the cardiovascular and respiratory systems and leads to improvements in the body's utilization of oxygen. most effective way to improve cardiorespiratory fitness and VO2 max Improvements in VO2 max should be the goal Many of the cardiovascular and metabolic health benefits from exercise can be attributed to improvements in VO2 max.
time
Exercise sessions should last between 20-60 minutes per session depending on the intensity of the exercise session. Higher intensity exercise sessions should be shorter and lower intensity exercise should be longer.
intensity
For most adults moderate to vigorous intensity exercise should be performed for improving cardiorespiratory fitness Previously sedentary individuals should begin with light to moderate intensity activities when starting an exercise program.
calculating exercise intensity
Max HR HRR VO2 Max VO2 reserve METS RPE
frequency
Moderate intensity = at least 5 days a week. Vigorous intensity = at least 3 days a week. Vigorous intensity aerobic exercise >5 days/week should be avoided in most cases. However, it can be undertaken with highly trained clients who vary their activity type. A combination of moderate and vigorous= 3-5 days per week.
RPE
Simple, yet accurate Sometime's called Borg's RPE scale Measured as either 6-20 or 1-10 with 10/20 being the hardest possible exercise and 1/6 being no exertion at all.
HR max equation
Target HR = Max HR x intensity %
VO2 max equation
Target VO2 = MaxVO2 x intensity %
VO2 reserve equation
Target VO2VOR = (Max VO2-RestVO2) x intensity % + RestVO2
MET (metabolic equivalent)
The amount of oxygen required per minute under resting, sitting conditions. It is approximately 3.5 mL of oxygen consumed per kilogram of body weight per minute (mL ⋅ kg -1 ⋅ min -1).
VO2 Max
This intensity is expressed as a % of this You are less likely to use this value in actual training because it is difficult to obtain this, but you WILL see this on the test. To calculate you will just multiply % intensity by this.
METS
This method stands for metabolic equivalents. You will likely not use this in practice, but will likely see at least one question on the exam about it. 1 of these = 3.5 ml/kg/min. To determine this value of an exercise, you will divide VO2 by 3.5.
VO2 Reserve
This similar to HRR Intensity= VO2 at rest + % intensity x VO2R (VO2 max-resting) Resting VO2 is usually not measured, and the average resting VO2 is 3.5 ml/kg/min
MET-minutes
an index of energy expenditure that quantifies the total amount of physical activity performed in a standardized way
RPE intensities
light <11 mod 12-13 vigorous 13-17 near max >17
HRR intensities
light <40% mod 40-59% vigorous 60-89% near max >90%
VO2 reserve intensities
light <40% mod 40-59% vigorous 60-89% near max >90%
VO2 max intensities
light <46 mod 46-63 vigorous 64-90 near max >90
HR max intensities
light <64 mod 64-76 vigorous 77-95 near max >95
kilocalorie (kcal)
the amount of heat energy required to raise the temperature of 1 kg of water by 1°C.
uphill running
will engage the back of the legs more (i.e. hamstrings, calves, glutes)
downhill running
will engage the quads more (eccentrically)
500-1,000 met/mins/wk or more is equivalent to _____ kcal/wk of moderate intensity PA (about 150 min/wk)
1,000
Max HR
HR max is the highest a person's heart rate will go. Intensity can be expressed as % of HR max HR goes down with age Predicted HR max 220-age
HRR
Intensity expressed as % of this Intensity=Resting HR + %intensity x HRR (HR max- resting heart rate)
HRR Equation
Target HR = (MaxHR-RestHR)x intensity % + RestHR
continuous training
refers to a type of aerobic exercise in which you maintain a consistent pace for the duration of the exercise. This is the traditional type of exercise that has been the most common form of aerobic exercise for decades.
interval training
refers to using training intervals of very high-intensity exercise followed by a lowered intensity/rest period.
