It is assumed that oxygen consumption is proportional to energy expenditure, assuming that everyone uses 3.5mL oxygen/kg/minute
So, 1 MET = 3.5mL/kg/min.
Disadvantages:
- This is only an approximation of energy expenditure because each individual will have varying metabolic efficiencies and different rates at which energy is burnt. Will not be specialised for the individual.
- Does not account for individual variations like age, gender, muscle mass, risk of disease/sickness and other environmental factors. 

Advantages:
Provides a generalised way of measuring exercise intensity and can be used as an overall guideline/indicator ]]> 2018-03-12 01:40:05 UTC https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240669167 Definitions https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240669353  
  1. Physical Activity: Any bodily movement produced by skeletal muscles that results in energy expenditure.
 
Exercise: Physical activity that is planned, structured, repetitive and performed with the with the intention of improving or maintaining one or more components of physical fitness. 
 
Fitness: A set of measurable attributes that a person has achieved.

The drivers of London double-decker buses were more likely to die suddenly of heart complications than conductors, who spent most of their time walking the aisles of the buses and climbing up and down the stairs to collect fares.]]> 2018-03-12 01:41:20 UTC https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240669386 Measures of Exercise Intensity https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240669472 Maximal oxygen (V ˙ O 2max )

Secondary: Intervention after onset of disease and controlling the effects of the disease (e.g. CVD, Diabetes, Anxiety/Depression).]]> 2018-03-12 01:44:27 UTC https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240669970 https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240671301
There appears to be a curvilinear relationship between physical activity and health, such that those individuals who are sedentary or get minimal physical activity benefit the most from relatively modest increases in physical activity and physical fitness in terms of improvements in health status ]]> 2018-03-12 01:54:05 UTC https://padlet.com/nutr1023nm/28fknwf9vig2/wish/240671301
