The purpose of this study was to investigate the validity taking one's pulse rate during postexercsie as a means of estimating the heart rate (HR) during exercise. The subjects were 12 collegiate women who were not currently involved regular physical activity. HR was recorded during and following exercises performed at an intensity of 40, 50, 60, or 70% maximal oxygen uptake. The 4 methods of estimating exercise HR were done by measuring postexercise pulse rate for : (1) 6 sec and multiplied by 10, (2) 10 sec and multiplied by 6, (3) 15 sec and multiplied by 4, and (4) 15 sec and multiplied by 4 and plus 10 (15 + 10 - Method) . The results showed that the 15 + 10 - Method estimated the exercise HR most accurately among these 4 methods.

BACKGROUND : Several large studies of obesity and the risk of adenomatous colorectal polyps have found no association among women but a reasonably consistent positive association among men. In women, a positive association that is stronger among or limited to those who are premenopausal has been suggested by studies that stratified analyses by age, although no previous study has examined the association according to menopausal status.
SUBJECTS AND METHODS : The risk of developing colorectal polyps was studied in 4, 053 of our female‘Human Dry Dock’subjects. They constitute a subset of 4, 053 (2, 476 premenopausal, 1, 577 postmenopausal) women originally examined from April 1998 to March 2004 and who underwent colonoscopy. Eligible women were 26-84 years old (mean age±SD : 48.1±7.9) and were free of invasive cancer, hyperplasia and familial polyposis. Adenomatous polyps were found in 235 (117 premenopausal, 118 postmenopausal) subjects but not in the remaining 3, 818 (2, 359 premenopausal, 1, 459 postmenopausal) subjects.
RESULTS : We found that obesity (body mass index : BMI ≥ 25) was associated with an approximately two-fold increased risk of colorectal polyps among premenopausal women compared with non-obese subjects (BMI < 25) (odds ratio 1.68, 95% confidence interval 1.18 - 2.53, p = 0.01) . There was no association between obesity and colorectal polyps among postmenopausal women (p = 0.89), and only a weak positive association in the entire cohort.
CONCLUSIONS : Our data suggest that obesity is associated with a two-fold increased risk of colorectal polyps in premenopausal women but not in postmenopausal women. Effect modification by menopausal status may better explain the inconsistent or weak findings in previous studies than the presumed lack of an association among women. These results should be confirmed by additional epidemiological studies.

Results of annual health examination (2006) of the workers in a drug store chain were evaluated. This company has own health evaluation system. But these results were re-evaluated by the standard evaluation system by Japan Society of Ningen Dock for comparing results from various companies. Tests examined for ones over 35 years of age were different from those for ones below 35 years of age. Ones who had unhealthy results were 7% for men and women below 35 years of age, 76.5% of men over 35 years of age, and 63.2% for women over 35 years of age. Among these, ones who had newly found unhealthy results to visit doctors were 1.6% for men below 35 years of age, 0% for women below 35 years of age, 43% for men over 35 years of age, and 36.8% for women over 35 years of age. These results were almost similar for workers of a food processing company and about twice higher than those for workers of an IT company where the author works as a part-time health control doctor. Age dependent changes of average test data for each examination were also calculated and physical meanings of these changes were discussed.
