Exercise Recommendations for Weight Loss
1. 減少慢性病發生的建議量 --每天至少 30分鐘的中等強度運動2. 減肥或維持體重的建議量 --每天 60分鐘的中等到激烈強度的運動3. 減肥後的體重維持或要繼續減肥 --每天 60 ~ 90分鐘的中等到激烈強度

Definition
Physical activity, is any bodily movement produced by the contraction of skeletal muscles resulting in caloric expenditure, includes LTPA and OPA.
Exercise, is a sub-category of physical activity and is activity which is planned, structured and repetitive.
Metabolic Calculations
BMR=BM × 24 × 1.05 kcal/day (H-B equation or indirect measure maybe needed for specific individuals)
TEE = BMR × activity factor activity factor = 1.2 for sedentary activity factor = 1.4 for moderately active
Based on energy deficit of 1,000 kcal/day Diet control = TEE – 600 kcal/day Exercise prescription = 400 kcal/day or 2,800 kcal/wk
Losing Weight through Structured Exercise
Pre-test screen (PAR-Q) Chronic condition Build up gradually for sedentary individuals Cross train to reduce overuse injuries
Exercise prescription for weight loss Primary cardiovascular (aerobic) activities 200-300 min per week or >2000 kcal/wk 55-70% of maximal heart rate

Exercise Prescription
What intensity? Too low
Takes too long to achieve energy expenditure target Inadequate stimulus for aerobic fitness
Too high Premature cessation of exercise
55-70% of HRmax
How frequent? At least 5 days/wk 7 days/wk for diabetics

Exercise Recommendations for Increase of Physical Activity
Assessment1) Medical and psychological readiness (PAR-Q)
2) Physical limitations (eg. knee OA, poor fitness etc.)
3) Current activities
4) Barriers to activity
Develop physical activity plan, LTPA or OPA Start activity slowly and gradually increase planned
aerobic activity to 300 min/wk Enhance compliance
Programmed vs lifestyle activity At-home vs onsite activity Multiple short bouts vs single long bout of activity
