someones with sedentary jobs have been shown to have an increased risk of cardiovascular morbidity and mortality compared with those who have active do job-works Because of the movement in the piece of work environment to more sedentary activities, the amount of self-reported activity during leisure time has been shown to have a positive purport on cardiovascular risk. Even light to moderate physical activity in women has been shown to provide more [i]or[/i] less cardiac protection. Results of studies examining the protective impact of physical activity in succession subclinical atherosclerosis have been mixed. Nordstrom and colleagues evaluated the relationship between physical activity during work and leisure time forward the progression of subclinical atherosclerosis in middle-aged men and women

The trial was a longitudinal cogitation of utility company employees between 40 and 60 years of age. The exclusion criteria were a self-reported history of cardiovascular disease and popular treatment for cancer. Participants in the meditation were randomly selected from all employee and assessed for intima-media thickness of the public carotid arteries by B-mode ultrasound scans at baseline and at 15 years and 3 years after the start of the subject of attention Physical activity was assessed at the three examinations at a nurse-assisted questionnaire. Physical activity evens were divided into three categories--sedentary, moderate, and vigorous. The sedentary assemblage included those who were in the lowest quartile of the general activity measure. Vigorous activity included those who participated in aerobic activity 35 times through week or more. Moderate activity included those who did not befitting the sedentary or vigorous activity definitions. Other measurements included family pressure, anthropometric measures, and fasting serum and plasma samples.

Of the 500 [i]role[/i]s who participated in the subject of attention 54 percent (268 persons) were men and the average age of the participants was 50 years. Twenty-four percent (120 persons) of the participants were identified as rife smokers, and 27 percent (135 persons) as former smoker Vigorous activity flushs were correlated with total and leisure activity still not with work activity. The intima-media thickness through the three-year period was 55 microns among those in the vigorous activity assign places to 10.2 microns in the moderate assemblage and 14.3 microns in the sedentary assemblage This was a significant difference for the sweep when controlling for sex and age variables.

The vigorous activity cluster had a lower body mass index, a slower resting heart rate, and an increase in high-density lipoprotein cholesterol compared with living bodys in the moderate activity form into groups The sedentary group had a higher resting heart rate compared with somebodys in the moderate activity group

The authors end that physical activity during leisure time has a efficient inverse relationship to the progression of subclinical atherosclerosis in the carotid arteries. They add that vigorous activity provides the best consequence s but that even moderate activity provides benefits. Therefore, level moving patients from a sedentary leisure lifestyle to moderate activity flushs would reduce the progression of atherosclerosis.
