Physical Activity Guidelines for Americans - 2008 Implications for Cardiovascular Disease Prevention & Management William L. Haskell, PhD Stanford Prevention Research Center & Division of Cardiovascular Medicine School of Medicine, Stanford University Presentation Outline Evolution of Physical Activity & Public Health Guidelines Physical movement rules for general wellbeing change versus rules for ideal body weight administration Physical Activity Guidelines for Americans - 2008 Guidelines - CVD counteractive action & administration A methodology in light of late research & incorporation

Slide 2

The Exercise Training Paradigm Early rules & proposals ( AHA 1972, 1975, ACSM 1978, 1990 ) were construct fundamentally with respect to continuance activity to improve execution - particularly cardiorespiratory wellness . Overwhelming activity ≥ 20 min ≥ 3 x week TRAINING PERFORMANCE RATIONALE: Increases in vigorous limit are most quickly accomplished by expanding the force of continuance activity and higher oxygen consuming limit is connected with lessened danger of CVD

Slide 3

Background - Physical Activity and CVD Prevention In 1992 the American Heart Association made physical latency their fourth. major CHD hazard element (added to cigarette smoking, hypertension and elevated cholesterol). In 1996 a NIH Consensus Development Panel presumed that physical latency was a noteworthy, free hazard element for CHD. In 1996 in Physical Activity and Health: A Report of the Surgeon General it was reasoned that physical latency was a noteworthy, autonomous danger variable for CHD.

Slide 4

The Physical Activity - Health Paradigm Public wellbeing focused rules subsequent to 1995 (CDC/ACSM, Surgeon General Report, NIH accord board). incorporate the aggregation of ≥ 30 minutes of moderate force action on most days of the week & overwhelming proposal still applies. ACTIVITY HEALTH RATIONALE: Data from observational and exploratory studies exhibit wellbeing related results from moderate force movement amassed for the duration of the day.

Slide 5

Rationale to Update 1995 and 1996 Recommendations Since 1995 significant measure of new research distributed on medical advantages of physical movement - some of it invigorated by 1995 proposals. There were various inquiries raised by how the 1995 suggestions were expressed. Proposals from different associations were making disarray, particularly about the measure of activity prescribed - particularly suggestions managing basically with anticipation of undesirable weight pick up, weight reduction and weight recover.

Slide 6

Dietary Guidelines for Americans - 2005 USDHHS & USDA, January 2005 PHYSICAL ACTIVITY To lessen the danger of unending malady in adulthood take part in no less than 30 minutes of moderate-power physical movement, above common action on most days of the week. For a great many people, more prominent medical advantages can be gotten by taking part in physical movement of more vivacious power or more length. To oversee body weight and counteract slow, unfortunate body weight pick up in adulthood: Engage in around a hour of moderate-to energetic force movement on most days while not surpassing caloric admission necessities.

Slide 7

Dietary Guidelines for Americans - 2005 USDHHS & USDA, January 2005 PHYSICAL ACTIVITY (proceeded) To maintain weight reduction in adulthood: Participate in no less than 60 to a hour and a half of every day moderate-force physical action while not surpassing caloric admission prerequisites. A few people may need to counsel with a medicinal services supplier before partaking in this level of movement. Accomplish physical wellness by including CV molding, extending practices for adaptability, & resistance activities or workout for muscle quality & continuance.

Slide 8

CDC and DHHS - an Issue Regarding Federal Physical Guidelines In 2002 advancement of redesign to 1995 PA & PH proposals began by CDC and ACSM. In 2006 when cutting-edge draft of the two original copies were evaluated by CDC, they were required to get DHHS endorsement. DHHS & CDC chose not to issue new suggestions since Federal Physical and Health Recommendations existed - as a major aspect of the Dietary Guidelines for Americans - 2005. ACSM and AHA continued with distributions of the upgraded suggestions in 2007.

Slide 9

Physical Activity & Public Health - 2007 Recommendations for Generally Healthy Adults To advance and keep up great wellbeing and anticipate incessant malady, grown-ups ought to perform moderate-force (3.0 - 6.0 METS) vigorous (perseverance) physical movement for at least 30 minutes on five days every week. On the other hand, this proposal can be met by performing lively force action for no less than 20 minutes on 3 days every week. Blends of moderate-and overwhelming force continuance activity can be performed to meet this suggestion. This movement is notwithstanding the required exercises of every day living that are of light power or brief span.

Slide 10

Physical Activity Recommendations (cont.) Given the general measurement reaction connection between physical movement and interminable malady anticipation, more noteworthy advantages will come about because of surpassing these proposals. The ≥ 30-minute focus for moderate-force activity can be amassed for the duration of the day in episodes of ≥ 10 minutes. All grown-ups ought to incorporate a regimen of resistance (quality creating) exercise 2 x week comprising of maybe a couple sets of 8-10 practices with 10-12 reiterations at close maximal exertion including all real muscle gatherings of the body.

Slide 11

Physical Activity Recommendations for Healthy Adults ≥ 65 Years of Age Aerobic Activity: ≥ 30 minutes of moderate power on 5 days/week or ≥ 20 minutes of lively force on 3 days/week. Muscle-strengthing movement: 8-10 practices @ 10-15 reps performed on 2 non-successive days Flexibility works out: 10 minutes on ≥ 2 days/week Balance advancing action: ought to perform exercises that keep up parity and avert falls. Other: more movement = more noteworthy advantage, can consolidated moderate with fiery to meet objectives, wellbeing should be considered

Slide 12

CDC and DHHS - an Issue Regarding Federal Physical Guidelines Lobbying inside and outside DHHS brought about the DHHS Secretary approving advancement of Physical Activity Guidelines for Americans - 2008 IOM workshop held October 2006 to build up that there was sufficient proof to continue. Physical Activity Guidelines Advisory Committee selected in February 2007 to set up a broad report on the proof connecting physical action and wellbeing between 1995-2007. DHHS staff to get ready rules and approach explanations. CDC approved to direct broad writing look on key wellbeing results - information distributed subsequent to 1995.

Slide 13

Outcome Areas All-cause mortality Cardiorespiratory wellbeing Musculoskeletal wellbeing Metabolic wellbeing Energy parity & upkeep of solid weight Cancer Functional wellbeing - particularly in more seasoned grown-ups Mental wellbeing Youth Adverse occasions & security Understudied populaces

Slide 14

Cardiorespiratory Health Summary - Review of Observational Studies Observational concentrates on giving an account of PA in essential counteractive action distributed between January 1996 and August 2007 CVD: 21 observational investigations of PA Men = 18 considers, >75,000 members Women = 17 thinks about, >300,000 members CHD: 23 observational investigations of PA Men = 14 studies, > 200,000 members Women = 16 examines, >275,000 members Stroke: 21 observational investigations of PA Men = 15 contemplates, >120,000 members Women = 17 ponders, >175,000 members

Slide 15

PAGAC Report - Cardiorespiratory Health What observational studies distributed following 1996 give - Improved procedure - better appraisal of PA, results and conceivable perplexing components Larger study populaces and more occasions More information on ladies and more established men More differing ethnic/race populaces Many studies give clinical result information on at any rate slightest three classes (levels) of action subsequently give some data on measurements reaction.

Slide 16

PAGAC - Consensus on Amount of Aerobic Activity "For some studies, the measure of moderate and lively force action connected with altogether bring down rates of malady or enhancements in biomarkers and wellness is in the scope of 500 to 1,000 MET-minutes every week." Note: the absence of exactness of the science crosswise over populaces and results manages wide range "A grown-up can accomplish an objective of 500 MET-minutes every week by strolling at around 3.0 miles for each hour for approximately150 minutes every week (7.5 miles), strolling quicker at 4.0 miles for each hour for 100 minutes (6.6 miles) or running or running at 6 miles for each hour for around 50 minutes for each week (5.0 miles). "

Slide 17

Physical Activity and Cardiorespiratory Health What is the connection between physical movement and cardiovascular malady bleakness and mortality? Conclusions Data from imminent companion studies and case-control studies (1995-2007) support a solid and predictable backwards relationship between level of physical action and CHD or CVD horribleness and mortality. Men and ladies who report moderate levels of physical action encounter a 20% - 25% lower hazard than their minimum dynamic partners, while those reporting larger amounts of action experience a 30% - 35% lower hazard than the slightest dynamic. In view of 68 study bunches in imminent associate studies and case-control thinks about with around 872,000 subjects.
