Tracking
Moderate activity according to CDC and ACSM guidelines
3.0 to 6.0 METs
Vigorous activity according to CDC and ACSM guidelines
Greater than 6.0 METs
Light intensity according to CSEP guidelines
≥1.5 – 4.0 METs
Example of light intensity
Light households chores, walking the dog
Moderate intensity according to CSEP guidelines
≥ 4.1 – 6.9 METs
Vigorous intensity according to CSEP guidelines
≥ 7.0 METs
Example of moderate intensity
Skateboarding, rollerblading, baseball, hiking
Example of vigorous intensity
Fast bike riding, running, jumping rope, basketball, soccer, cross country skiing
a MET of 1.0 = to what
Completely at rest
in words, what does 4 METs mean compared to 1 MET
Means that you are expanding 4 times the energy used at rest
3 methods used to measure, assess and monitor PA
HR monitor
Pedometers
Accelerometers
What is the best combination to measure PA
HR + accelerometer
Established link between PA and improvements in:
Cardiorespiratory fitness
Musculoskeletal fitness
Reduction in injuries
