The daily evaluation of the life style is funda- mental for the “exercise as prescription” to re- duce the cardiovascular risks factors. The reg- istration by an accelerometer can identify active from inactive subjects. The aim of the present study is to verify, in a small cohort of subjects at high risk level (obese–hypertensive), the health outcomes. A group of 22 subjects were evalu- ated by the questionnaire and also by an accel- erometer positioned on belt for 5 days to estab- lish the daily Physical Activity Level (PAL).The anthropometrics parameters, Body Mass Index (BMI), Waist Circumference, Hip Circumference, Fat Mass, Free Fat Mass, Total Body–Intracellular and Extracellular Water and Phase Angle (PA) were measured at the beginning and after 3 months of regular exercise. The amount of the exercise prescribed for three months and at least 3 times in a weak, was determined by the Cardiopulmonary test at the 60% of the VO2. Sta-tistical analysis included T-Student test for paired data with a significance at P < 0.05value. Respect of the questionnaire the accelerometer report showed a predominantly inactive life style (PAL = 1.49 ± 0.13). After three months the BMI was significantly reduced in all (p < 0.05) and in addi-tion a trend toward a reduction was also observed for Fatty Mass and for the body composition parameters. The employment of the accelerometer is therefore associated to an improvement of the parameters strongly related with the cardiovascular risk. The results obtained are suggestive for an educational role of this tool in subjects at high risk level
The assessment of the Spontaneous Motor Activity (SMA) of the life style (LS) is fundamental to establish the daily Physical Activity (PA) dose as therapy. The recent employment the accelerometer (AiperMotion 440 PC –Aipermon GmBH – Germany), can immediately distinguish “active” from “sedentary” subjects providing a larger adhesion to the exercise program. The study aims to verify the role of the accelerometer. 28 obese-hypertensive were evaluated either by the questionnaire or by the accelerometer. A larger sedentary LS in the population investigated was found by the accelerometer respect of questionnaire. After three months of regular physical exercise, the body compositions parameters, investigated principally, resulted to be improved. The accelerometer determines a real and objective visualization of the LS expressed as PAL resulting on a direct early improvement of the parameters strongly related with the cardiovascular risk. The results support the educational role of the employ of the accelerometer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
