“…Apart from the question of degree of exercise, it remains uncertain whether exercise itself is protective or whether it results in a favorable clustering of other factors associated with reduced risk. Among the latter are a decreased total serum cholesterol level (including decreased low density lipoproteins and increased high density lipoproteins), a decreased serum triglyceride level (Lopez-S et al, 1974;Fletcher and Cantwell, 1974;Wood et al, 1976;Cantwell, 1978), reduced systolic and diastolic blood pressure levels (Scheuer and Tipton, 1977), and increased vital capacity (Kannel, 1967). Similar decreases in serum lipids and blood pressure with swimming or running activity have been described for the rat (Papadopolou° et al, 1969;Tipton et al, 1977).…”

SUMMARY It is possible that one of the consequences of regular physical activity could be a change in vascular metabolism. We studied the effects of regular swimming activity on specific activities of aortic hydrolases of male rats. Enzymes included: neutral a-glucosidase and lysosomal /3-galactosidase, JV-acetyl-/}-glucosaminidase, cathepsin C, acid a-glucosidase, and acid cholesteryl esterase. After 8 or 16 weeks of a 1-hour/day swimming protocol, specific activities of four of the six aortic enzymes studied were increased over control levels, increases ranging from 7 to more than 42%. Acid cholesteryl esterase was one of the enzymes most affected by the exercise, increasing 25-30% above control levels. An 8-week sedentary period, after 8 weeks of a swimming regimen, resulted in return of the activity of acid cholesteryl esterase, but not those of the other hydrolases, to control levels. Decreases in body weight, blood pressure, and serum lipid levels also occurred in the swimming rats. Weight reduction per se was excluded as an explanation for the increases in aortic enzymes or decrease in serum cholesterol found with swimming. These findings show that regular physical activity is yet another factor with discrete and significant effects on the catabolic activity of vascular tissue.

Apart from the question of degree of exercise, it remains uncertain whether exercise itself is protective or whether it results in a favorable clustering of other factors associated with reduced risk. Among the latter are a decreased total serum cholesterol level (including decreased low density lipoproteins and increased high density lipoproteins), a decreased serum triglyceride level (Lopez-S et al., 1974;Fletcher and Cantwell, 1974;Wood et al., 1976;Cantwell, 1978), reduced systolic and diastolic blood pressure levels (Scheuer and Tipton, 1977), and increased vital capacity (Kannel, 1967). Similar decreases in serum lipids and blood pressure with swimming or running activity have been described for the rat (Papadopolou° et al., 1969;Tipton et al., 1977).We recently (Wolinsky and Fowler, 1978) have emphasized the importance of understanding the direct effects of putative risk factors for vascular disease on cellular metabolism of the blood vessel wall in addition to noting the levels of certain circulating lipoprotein classes, the blood pressure

“…As cigarette smoking, excessive alcohol intake and overeating are associated as major risk factors with hyperlipidemia and other cardiovascular diseases89 , 11-'3), and physical activity has been shown to be significantly negatively associated with these diseases-5, 1720, [27][28][29] periods of exercise in daily prison life isolated from these risk factors may be of benefit in preventing the diseases.…”

This prospective study of female prison inmates assessed the effects of prison labour life style on the blood pressure (BP), serum lipids, and body mass index of pre-and postmenopausal female prisoners. This study was carried out in the largest women's prison, located in a town in the North East of Japan. The prison serves a reasonably large community. Three hundred and twelve premenopausal female prisoners and 88 postmenopausal female prisoners in a women's prison participated in this study. Weight and height were measured to calculate the body mass index, and systolic and diastolic blood pressure were measured with a sphygmomanometer.Serum samples were collected for serum lipid estimations. Base-line data of two groups were compared by unpaired t-test, and changes in these data from the initial values were tested by paired t-test. From our limited data, both the pre-and postmenopausal female prisoners showed decreases in systolic and diastolic pressure, total cholesterol, triglycerides, LDL-cholesterol, and body mass index. Both also showed increases in HDL-cholesterol. Given that almost all the women in this prison had the same labour life style, the findings of this study suggest that BP, the serum lipids concentration and obesity can be changed effectively by prison labour life, but are less readily changed in postmenopausal than in premenopausal women.

“…Numerous studies confirm a connection between other types of aerobic exercise, besides walking, and favorable levels of serum cholesterol. [2][3][4][5][6] Because subjects in the present study had relatively high socioeconomic status and education levels, generalization to poorer, less educated groups will necessitate further research.…”
