A

20-30%

117
Q

Physically active commuting (cycling/walking) decreases hazard ratio of CHD to what?

A

-Triglycerides
-Fasting glucose
and reduced CVD risk

Q

What must be combined with PA to lose weight and maintain it?

A

reduced caloric intake

PA levels = strong predictor of longterm wgt maintenance / stabilisation than diet alone!

How many years of life lost were demonstrated for:

a) overweight who met PA guidelines compared to normal weight physically active?
b) obese who met PA guidelines compared to normal weight inactive?

A

a) overweight PA vs Normal weight PA = 0 years lost

b) obese PA vs Normal weight inactive = same yrs lost
