24. National Physical Activity Guidelines for Ireland (Adults)  At least 30 minutes of moderate intensity physical activity on 5 days a week  30 mins can be accumulated over the day but you must be active for at least 10 mins each time to make it count  Also one min of vigorous activity counts as two mins of moderate activity, i.e. 15 mins of vigorous activity equals 30 mins of moderate activity needed each day  Same for older adults  Adults with disabilities - be as active as your ability allows, aim to meet adult guidelines

25. National Physical Activity Guidelines for Ireland (Adults)  It should be noted that to lose weight 60 – 75 mins of moderate intensity activity a day may be required  If you have lost a significant amount of weight, to maintain weight loss, 60 - 90 mins of moderate physical activity a day necessary to prevent weight gain.  45-60 mins (IASO 2004), 60-90 mins per day (ACSM & AHA 2008)  A combination of diet and exercise appears to be the optimal strategy both for reducing weight and for maintaining weight loss.

The prevalence of decreases in hypoglycemic medications were 15% in the control, 22% in the resistance training, 19% in the aerobic, and 26% in the combination training groups (P =.20). The prevalence of individuals who achieved the composite outcome of either decreasing hypoglycemic medication or reducing HbA 1c by 0.5% without increasing medications were 22% in the control group, 26% in the resistance training, 29% in the aerobic, and 41% in the combination training group

42. Stress Testing Vigorous For exercise more vigorous than brisk walking or exceeding the demands of everyday living, sedentary and older diabetic individuals will likely benefit from being assessed for conditions that might be associated with risk of CVD, contraindicate certain activities, or predispose to injuries, including severe peripheral neuropathy, severe autonomic neuropathy, and preproliferative or proliferative retinopathy

48. Physical Activity and Mortality DM Total PA was associated with lower risk of CVD and total mortality. Compared with physically inactive persons, the lowest mortality risk was observed in moderately active persons: Hazard ratios were 0.62 (95% CI, 0.49-0.78) for total mortality and 0.51 (95% CI, 0.32-0.81) for CVD mortality. Leisure-time PA was associated with lower total mortality risk, and walking was associated with lower CVD mortality risk. In the meta-analysis, the pooled random-effects hazard ratio from 5 studies for high vs low total PA and all-cause mortality was 0.60 (95% CI, 0.49-0.73).

51. METs3.5-4  Moderate  Walking at a brisk pace (1 mi every 20 min)  Weight lifting, water aerobics  Golf, not carrying clubs  Leisurely canoeing or kayaking  Walking at a very brisk pace (1 mi every 17 to 18 min)  Climbing stairs  Dancing (moderately fast)  Bicycling <10 mph, leisurely

52. METs4.5-6 Moderately Vigorous Plus Slow swimming Golf, carrying clubs Walking at a very brisk pace (one mi every 15 min) Most doubles tennis Dancing (more rapid) Some exercise apparatuses Slow jogging (one mi every 13 to 14 min)

53. Vigorous Exercise  Hiking  Rowing, canoeing, kayaking vigorously  Dancing (vigorous)  Some exercise apparatuses  Bicycling 10 to 16 mph  Swimming laps moderately fast to fast  Aerobic calisthenics  Singles tennis, squash, racquetball  Jogging (1 mile every 12 min)  Skiing downhill or cross country

56. Why Resistance Training? Improves metabolism – proven reduction in Insulin Resistance, incidence of D.M., additive effect to aerobic exercise in prevention and treatment of IHD Improves muscle strength – less falls/#s Reduced Osteoporosis 1year increase BMD 1.3% Controls loss 1.2% Arthritis – Reduced pain Improved function

57. Exercise that uses muscular strength to move a weight or move against a resistive load In diabetes resistance exercise of the major muscle groups on 2 non consecutive days in the week is recommended

58. Resistance Training Resistance can be own body weight Press Up / Sit Up Light Weights – Dumb Bells Resistance bands

62. Progression Over time and as the person achieves 3 sets of 10-15 reps the weight can be increased, as this produces impoved blood glucose effects As the weight increases the number of reps per set can be reduced to 8-10

63. 7 Investments that work for physical activity 1. Whole-of-school’ programs 2. Transport policies and systems that prioritise walking, cycling and public transport 3. Urban design regulations and infrastructure that provides for equitable and safe access for recreational physical activity, and recreational and transport-related walking and cycling across the life course 4. Physical activity and NCD prevention integrated into primary health care systems 5. Public education, including mass media to raise awareness and change social norms on physical activity 6. Community-wide programs involving multiple settings and sectors & that mobilize and integrate community engagement and resources 7. Sports systems and programs that promote ‘sport for all’ and encourage participation across the life span
