Spontaneous Physical Activity Before To Start With The Exercise As Prescription Program

Introduction: In subjects at high risk level, a correct investigation of the daily Spontaneous Physical Activity (SPA) as time, frequency, intensity and kind of exercise can play a relevant role to start with the “exercise as prescription” program. The aim of the study is to evaluate, in a group of obese - hypertensive patients the real SPA at the beginning of the exercise as prescription by the accelerometer report. Methods: The daily life style has been evaluated in a group of 30 obese –hypertensive patients (20 male and 10 female) aged 57.48±12.77 for 6 days by the accelerometer (AiperView 440). It has been positioned on the waist circumference of every subject analyzed. A PA more than 3 hours a week represents the point to distinguish sedentary from active subjects, however several else parameters were analyzed: the Physical Activity Level (definite as EE /resting Energy Expenditure), medium daily distance and intensity of the PA expressed as slow (up to 3 Km/h) or fast (up to 5/km/h) walk , and also the number of total daily steps. Results: The PAL (Physical Activity Level) observed was 1.57±0.16 , medium daily distance was 6300.27±2525.15 m. The amount of time in 6 days spent as sedentary were 50±8.52 hours; the hours as exercise corresponding to 3 METS were 22.5±6.13, the time practicing exercise as 3-4.5 Mets was 11.23±3.89 hours, and the minutes spent for jogging were 72.41±80.67. The time of hours corresponding to the different degree of the daily PA were 8h 15 min sedentary, 3h 45 min slow walk, 1h 50 min fast walk. The number of the daily steps was around 9413.25±4003.12 in all the subjects analyzed. The daily calories spent were 889.5±272.02. Conclusions: The data obtained demonstrates the accelerometer can typify the intensity and the kind of exercise performed including information related to the SPA with a good definition of the LS. The identification of the presence moderate PAL in a group at high risk level, could therefore play a relevant role inducing to start with a “more adequate” PA program in these subjects balancing the moderate with intense exercises.
