-Secondary tries to reduce the progression of a disease, focuses on unhealthy individuals. ]]> 2018-03-12 04:21:10 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240688585 Explain what was found in the early studies of London bus drivers and conductors in the 1950s. https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240688674 2018-03-12 04:21:53 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240688674 MET https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240688925 What are the limitations of using metabolic equivalents (METs) to measure exercise intensity? 
The limitations of MET's are: 
- it is only an approximation of energy expenditure. 
- There could be potential errors in using the 1.0 MET(resting metabolic rate) as the constant resting value. 
- Does not take into account age, sex, muscle mass or disease states. 
- Only be used as a guideline for training in a general sense. ]]> 2018-03-12 04:24:16 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240688925 Different methods of measuring exercise intensity https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689045 - Maximal oxygen consumption
- Oxygen consumption reserve
- Heart rate reserve
- Maximal Heart Rate
- Metabolic Equivalent ]]> 2018-03-12 04:25:05 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689045 https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689057 physical activity- any bodily movement produced by skeletal muscle that requires energy expenditure.]]> 2018-03-12 04:25:11 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689057 What types of studies are mostly used as evidence for the health benefits of physical activity? Describe the strengths and limitations of these types of studies. https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689182 Cohort studies (longitudinal studies)-typically observe large groups of individuals, recording their exposure to certain risk factors to find clues as to the possible causes of disease.
STRENGTHS:
-        Identify cohort, representative of population 
-        Follow over many years 
-        Collects data on exposures and outcomes 
-        Data rich 
-        Same people are measured, so minimises the effects of other variables 

LIMITATIONS:
-        Attrition (drop out/ mortality) 
-        Familiarity with the experiment 
-        Non equivalence of those who dropped out with those who stayed in 

Others include:
- Laboratory- based studies 
- Large scale population- based observation studies

individuals who already meet their minimum requirements of weekly physical activities are likely to derive some additional health and fitness benefits from becoming more physically active.]]> 2018-03-12 04:28:40 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689434 • List the different domains of physical activity. https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689466 - Leisure, sport, exercise, transport, occupation, house and yard ]]> 2018-03-12 04:29:02 UTC https://padlet.com/nutr1023nm/fhh2q3dao6w3/wish/240689466
