WHO DEFINITIONS OF CONCEPTS USED IN THE RECOMMENDED LEVELS OF PHYSICAL ACTIVITY • TYPE (WHAT TYPE). THE MODE OF PARTICIPATION IN PHYSICAL ACTIVITY. THE TYPE OF PHYSICAL ACTIVITY CAN TAKE MANY FORMS: AEROBIC, STRENGTH, FLEXIBILITY, BALANCE. • DURATION (FOR HOW LONG). THE LENGTH OF TIME IN WHICH AN ACTIVITY OR EXERCISE IS PERFORMED. DURATION IS GENERALLY EXPRESSED IN MINUTES. • FREQUENCY (HOW OFTEN). THE NUMBER OF TIMES AN EXERCISE OR ACTIVITY IS PERFORMED. FREQUENCY IS GENERALLY EXPRESSED IN SESSIONS, EPISODES, OR BOUTS PER WEEK. • INTENSITY (HOW HARD A PERSON WORKS TO DO THE ACTIVITY). INTENSITY REFERS TO THE RATE AT WHICH THE ACTIVITY IS BEING OF PHYSICAL ACTIVITY PERFORMED OR THE MAGNITUDE OF THE EFFORT REQUIRED TO PERFORM AN ACTIVITY OR EXERCISE. VOLUME (HOW MUCH IN TOTAL). AEROBIC EXERCISE EXPOSURES CAN BE CHARACTERIZED BY AN INTERACTION BETWEEN BOUT INTENSITY, FREQUENCY, DURATION, AND LONGEVITY OF THE PROGRAMME. THE PRODUCT OF THESE CHARACTERISTICS CAN BE THOUGHT OF AS VOLUME. • MODERATE-INTENSITY PHYSICAL ACTIVITY. ON AN ABSOLUTE SCALE, MODERATE INTENSITY PHYSICAL ACTIVITY .

MORE TIMES FOR CHILDREN AND YOUTH. ON A SCALE RELATIVE TO AN INDIVIDUAL’S PERSONAL CAPACITY, VIGOROUSI NTENSITY PHYSICAL ACTIVITY IS USUALLY A 7 OR 8 ON A SCALE OF 0–10. • AEROBIC ACTIVITY. AEROBIC ACTIVITY, ALSO CALLED ENDURANCE ACTIVITY, IMPROVES CARDIORESPIRATORY FITNESS. EXAMPLES OF AEROBIC ACTIVITY INCLUDE: BRISK WALKING, RUNNING, BICYCLING, JUMPING ROPE, AND SWIMMING. • SCALA DI PERCEZIONE DELLA FATICA PUBLIC HEALTH SIGNIFICANCE OF PHYSICAL ACTIVITY IT IS ESTIMATED CURRENTLY THAT OF EVERY 10 DEATHS, 6 ARE ATTRIBUTABLE TO NCDS PHYSICAL INACTIVITY IS ESTIMATED AS BEING THE PRINCIPAL CAUSE FOR APPROXIMATELY 21–25% OF BREAST AND COLON CANCER BURDEN, 27% OF DIABETES AND APPROXIMATELY 30% OF ISCHAEMIC HEART DISEASE BURDEN IN ADDITION, NCDS NOW ACCOUNT FOR NEARLY HALF OF THE OVERALL GLOBAL BURDEN OF DISEASE.

PREGNANT, POSTPARTUM WOMEN AND PERSONS WITH CARDIAC EVENTS MAY NEED TO TAKE EXTRA PRECAUTIONS AND SEEK MEDICAL ADVICE BEFORE STRIVING TO ACHIEVE THE RECOMMENDED LEVELS OF PHYSICAL ACTIVITY FOR THIS AGE GROUP. INACTIVE ADULTS OR ADULTS WITH DISEASE LIMITATIONS WILL HAVE ADDED HEALTH BENEFITS IF MOVING FROM THE CATEGORY OF “NO ACTIVITY” TO “SOME LEVELS” OF ACTIVITY. ADULTS AGED 65 YEARS AND ABOVE SHOULD DO AT LEAST 150 MINUTES OF MODERATE-INTENSITY AEROBIC PHYSICAL ACTIVITY THROUGHOUT THE WEEK OR DO AT LEAST 75 MINUTES OF VIGOROUS-INTENSITY AEROBIC PHYSICAL ACTIVITY THROUGHOUT THE WEEK OR AN EQUIVALENT COMBINATION OF MODERATE- AND VIGOROUSINTENSITY ACTIVITY. AEROBIC ACTIVITY SHOULD BE PERFORMED IN BOUTS OF AT LEAST 10 MINUTES DURATION. FOR ADDITIONAL HEALTH BENEFITS, ADULTS AGED 65 YEARS AND ABOVE SHOULD INCREASE THEIR MODERATE INTENSITY AEROBIC PHYSICAL ACTIVITY TO 300 MINUTES PER WEEK, OR ENGAGE IN 150 MINUTES OF VIGOROUS INTENSITY AEROBIC PHYSICAL ACTIVITY PER WEEK, OR AN EQUIVALENT COMBINATION OF MODERATE-AND VIGOROUS-INTENSITY ACTIVITY. ADULTS OF THIS AGE GROUP, WITH POOR MOBILITY, SHOULD PERFORM PHYSICAL ACTIVITY TO ENHANCE BALANCE AND PREVENT FALLS ON 3 OR MORE DAYS PER WEEK. MUSCLE-STRENGTHENING ACTIVITIES SHOULD BE DONE INVOLVING MAJOR MUSCLE GROUPS, ON 2 OR MORE DAYS A WEEK. WHEN ADULTS OF THIS AGE GROUP CANNOT DO THE RECOMMENDED AMOUNTS OF PHYSICAL ACTIVITY DUE TO HEALTH CONDITIONS, THEY SHOULD BE AS PHYSICALLY ACTIVE AS THEIR ABILITIES AND CONDITIONS ALLOW. FOR ADULTS OF THIS AGE GROUP, PHYSICAL ACTIVITY INCLUDES RECREATIONAL OR LEISURE-TIME PHYSICAL ACTIVITY, TRANSPORTATION (E.G WALKING OR CYCLING), OCCUPATIONAL (I.E. WORK), HOUSEHOLD CHORES, PLAY, GAMES, SPORTS OR PLANNED EXERCISE, IN THE CONTEXT OF DAILY, FAMILY, AND COMMUNITY ACTIVITIES. IN ORDER TO IMPROVE CARDIORESPIRATORY AND MUSCULAR FITNESS, BONE HEALTH AND REDUCE THE RISK OF NCDS AND DEPRESSION THE FOLLOWING ARE RECOMMENDED: 1. ADULTS AGED 18–64 SHOULD DO AT LEAST 150 MINUTES OF MODERATEINTENSITY AEROBIC PHYSICAL ACTIVITY THROUGHOUT THE WEEK OR DO AT LEAST 75 MINUTES OF VIGOROUS-INTENSITY AEROBIC PHYSICAL ACTIVITY THROUGHOUT THE WEEK OR AN EQUIVALENT COMBINATION OF MODERATEAND VIGOROUS-INTENSITY ACTIVITY. 2. AEROBIC ACTIVITY SHOULD BE PERFORMED IN BOUTS OF AT LEAST 10 MINUTES DURATION. 3. FOR ADDITIONAL HEALTH BENEFITS, ADULTS SHOULD INCREASE THEIR MODERATE-INTENSITY AEROBIC PHYSICAL ACTIVITY TO 300 MINUTES PER WEEK, OR ENGAGE IN 150 MINUTES OF VIGOROUS-INTENSITY AEROBIC PHYSICAL ACTIVITY PER WEEK, OR AN EQUIVALENT COMBINATION OF MODERATE- AND VIGOROUS-INTENSITY ACTIVITY. 4. MUSCLE-STRENGTHENING ACTIVITIES SHOULD BE DONE INVOLVING MAJOR MUSCLE GROUPS ON 2 OR MORE DAYS A WEEK. OVERALL, ACROSS ALL THE AGE GROUPS, THE BENEFITS OF IMPLEMENTING THE ABOVE RECOMMENDATIONS, AND OF BEING PHYSICALLY ACTIVE, OUTWEIGH THE HARMS. AT THE RECOMMENDED LEVEL OF 150 MINUTES PER WEEK OF MODERATEINTENSITY ACTIVITY, MUSCULOSKELETAL INJURY RATES APPEAR TO BE UNCOMMON. IN A POPULATION-BASED APPROACH, IN ORDER TO DECREASE THE RISKS OF MUSCULOSKELETAL INJURIES, IT WOULD BE APPROPRIATE TO ENCOURAGE A MODERATE START WITH GRADUAL PROGRESS TO HIGHER LEVELS OF PHYSICAL ACTIVITY. AMSE NO STRATEGIES HAVE BEEN ADEQUATELY STUDIED TO EVALUATE THEIR ABILITY TO REDUCE EXERCISE-RELATED ACUTE CARDIOVASCULAR EVENTS. MAINTAINING PHYSICAL FITNESS THROUGH REGULAR PHYSICAL ACTIVITY MAY HELP TO REDUCE EVENTS BECAUSE A DISPROPORTIONATE NUMBER OF EVENTS OCCUR IN LEAST PHYSICALLY ACTIVE SUBJECTS PERFORMING UNACCUSTOMED PHYSICAL ACTIVITY. OTHER STRATEGIES, SUCH AS SCREENING PATIENTS BEFORE PARTICIPATION IN EXERCISE, EXCLUDING HIGH-RISK PATIENTS FROM CERTAIN ACTIVITIES, PROMPTLY EVALUATING POSSIBLE PRODROMAL SYMPTOMS, TRAINING FITNESS PERSONNEL FOR EMERGENCIES, AND ENCOURAGING PATIENTS TO AVOID HIGH-RISK ACTIVITIES, APPEAR PRUDENT BUT HAVE NOT BEEN SYSTEMATICALLY EVALUATED. Physiological alterations accompanying acute exercise and recovery and their possible sequelae. THE FOCUS OF THE GLOBAL RECOMMENDATIONS ON PHYSICAL ACTIVITY FOR HEALTH IS PRIMARY PREVENTION OF NCDS THROUGH PHYSICAL ACTIVITY AT POPULATION LEVEL THE PRIMARY TARGET AUDIENCE FOR THESE RECOMMENDATIONS ARE POLICY-MAKERS AT NATIONAL LEVEL.

HABITUAL PHYSICAL ACTIVITY REDUCES CORONARY HEART DISEASE EVENTS, BUT VIGOROUS ACTIVITY CAN ALSO ACUTELY AND TRANSIENTLY INCREASE THE RISK OF SUDDEN CARDIAC DEATH AND ACUTE MYOCARDIAL INFARCTION IN SUSCEPTIBLE PERSONS. Relative risk of MI associated with vigorous exertion (>6 METs) according to habitual frequency of vigorous exertion. "The paradox of physical exercise" HABITUAL PHYSICAL ACTIVITY REDUCES CORONARY HEART DISEASE EVENTS, BUT VIGOROUS ACTIVITY CAN ALSO ACUTELY AND TRANSIENTLY INCREASE THE RISK OF SUDDEN CARDIAC DEATH AND ACUTE MYOCARDIAL INFARCTION IN SUSCEPTIBLE PERSONS. EXERCISE-ASSOCIATED ACUTE CARDIAC EVENTS GENERALLY OCCUR IN INDIVIDUALS WITH STRUCTURAL CARDIAC DISEASE. HEREDITARY OR CONGENITAL CARDIOVASCULAR ABNORMALITIES ARE PREDOMINANTLY RESPONSIBLE FOR CARDIAC EVENTS AMONG YOUNG INDIVIDUALS, WHEREAS ATHEROSCLEROTIC DISEASE IS PRIMARILY RESPONSIBLE FOR THESE EVENTS IN ADULTS.

THERE APPEARS TO BE A GRADED LINEAR RELATION BETWEEN THE VOLUME OF PHYSICAL ACTIVITY AND HEALTH STATUS, SUCH THAT THE MOST PHYSICALLY ACTIVE PEOPLE ARE AT THE LOWEST RISK. HOWEVER, THE GREATEST IMPROVEMENTS IN HEALTH STATUS ARE SEEN WHEN PEOPLE WHO ARE LEAST FIT BECOME PHYSICALLY ACTIVE.

Sponsored by: EXERCISE IS MEDICINE ‘THE BENEFITS OF REGULAR PHYSICAL ACTIVITY ON HEALTH, LONGEVITY AND WELLBEING EASILY SURPASS THE EFFECTIVENESS OF ANY DRUGS OR OTHER MEDICAL TREATMENT.’ SIR LIAM DONALDSON ‘‘In a word, all parts of the body which were made for active use, if moderately used and exercised at the labor to which they are habituated, become healthy, increase in bulk, and bear their age well, but when not used, and when left without exercise, they become diseased, their growth is arrested, and they soon become old.’’ Hyppocrates Medicine’s view of exercise did not progress much in the subsequent two millenia, and exercise was primarily viewed as an activity for healthy people, but not for the chronically ill. The use of exercise as a medical treatment is an old concept, but one that did not start gaining acceptance until the 20th century. Today, exercise scientists are exploring the limits of exercise as a therapy—of exercise as a medicine. Br J Sports Med 2004;38:6–7. The first recorded anecdote of exercise as a treatment for heart disease is thought to be from William Heberden,who wrote of a man with angina pectoris in 1772: ‘‘I knew of one who set himself the task of sawing wood forhalf an hour every day, and was nearly cured’’.Ironically, Heberden did not know that angina pectoris is a cardiac disorder.‘‘ Physicians of the 1800s were interested in the role of exercise in maintenance of health, but the modern notion of exercise as a medical treatmentis thought to have originated with R Tait McKenzie. McKenzie perceived exercise as a technique to rehabilitate people with disabling injuries’’ William Osler, in the 1909 edition of The principles and practice of medicine, wrote that bed rest and baths at spas like Bad Nauheim were the optimal treatment for heart disease. In 1939, Paul Dudley White, the first cardiology professor at Harvard Medical School, co-authored a manuscript showing cardiac dilatation through aneurysm formation after myocardial infarction, and this was used as an argument against exercise after myocardial infarction. By 1958, Dr White had changed his views and coauthored a textbook on cardiac rehabilitation in which low level exercise was promoted.Then in 1968, the concept of bed rest was finally put to rest by the landmark paper of Bengt Saltin et al. In 60 years, physicians had learned that exercise was useful in rehabilitation of people with both musculoskeletal injuries and cardiovascular disease. ‘‘Our current understanding of exercise prescription is limited for most chronic diseases’’ Il concetto di “esercizio fisico come terapia”, nato in America già dal secolo scorso, si identifica con la pratica regolare e costante di questo, opportunamente stabilito e dosato come “intensità, frequenza e durata”, all’interno di un atto medico diagnostico – terapeutico complesso del quale la Medicina dello Sport, come disciplina internistica, ha la piena ed esclusiva competenza. La prescrizione dell’esercizio quindi ha effetti positivi sulla salute attraverso azioni specifiche sui meccanismi della malattia stessa , che rappresenta, a differenza dell’Attività Fisica Adattata, un atto sanitario con finalità terapeutiche.

ADVERSE EFFECTS ARE RELATED TO THE TYPE OF EXERCISE-FOR EXAMPLE, DELAYED ONSET MUSCLE SORENESS-AND THE SPECIFIC CHRONIC DISEASE-FOR EXAMPLE, CHEST PAIN IN ANGINA PECTORIS, JOINT PAIN IN ARTHRITIS, FATIGUE IN FIBROMYALGIA. La medicina dello sport è ad una svolta: dalla valutazione dei soggetti che possono far sport,gli idonei; alla valutazione dei soggetti che devono fare sport all’interno di un piano terapeutico,i pazienti.
