To elucidate the phenomenon of central fatigue, we investigated the changes in the plasma amino acid level and false neurotransmitter (FNT) level during ultra-endurance exercise. Twenty-one male Japanese participants of the 1993 Ironman Japan Contest, held at Lake Biwa, were examined. Blood sampling and a questionnaire on the Profile of Mood States (POMS) test were collected two days before, immediately after and one-day following the race. The POMS questionnaire showed various changes especially due to fatigue. Indeed, the fatigue score significantly increased after the race. Although the confusion score significantly increased after the race, it quickly recovered to the pre race level the following day. The plasma concentration of the branched-chain amino acids (BCAA) decreased after the race, while the level of aromatic amino acids (AAA) increased, thus resulting in a significant decrease in the BCAA/AAA ratio. The plasma level of octopamine, one type of FNT, significantly increased after the race (p<0.01) . The blood ammonia level increased after the race, but recovered to the pre-race level one-day after the race. Although no change was observed in the total tryptophan (Trp) level, the level of free Trp significantly increased during the race. The significant increases in the plasma 5-hydroxyindoleacetic acid (5HIAA), homovanillic acid (HVA) and HVA/dihydroxyphenylacetic acid (DOPAC) ratios thus suggest the serotonin (5 HT) and dopamine (DA) neuron systems activated after the race. In conclusion, ultra-endurance exercise caused a disorder of both the amino acid and monoamine metabolisms. Furthermore these changes were also related with mood changes, especially fatigue, i. e. central fatigue. These results suggest that the measurement of both the plasma BCAA/AAA ratio and FNT may therefore be useful in quantifying exercise induced central fatigue.

We examined the relationships between exercise, eating disorders, weight loss-related concerns/behaviors and weight-cycling (weight loss and regain ≥10%) . The subjects were comprised of 1123 female college students (aged 18.9 ± 1.1 yrs.) who each completed a questionnaire on eating attitudes [Eating Attitude Test (EAT) ], dieting behavior [Dieting Behavior Scale (DBS) ], purging behavior (self-induced vomiting and use of laxatives) and previous weight-cycling. Subjects were divided into four groups on the basis of their current regular exercise behavior as follows non-exercisers (Ns) (N=704), low-intensity, low-frequency exercisers (LLs) (N=106), moderate/high-intensity, low-frequency exercisers (MLs) (N=184) and moderate/high-intensity, high-frequency exercisers (MHs) (N=129) .
Analyses of variances showed significant differences among the four groups for weight and eating concerns, and weight loss behavior. Not only MHs, but also MLs exhibited higher Dieting subscale score ratings on the EAT than Ns. MHs and MLs also showed higher Structured- and Extraordinary-Diet subscale score ratings on the DBS than Ns and LLs. Significantly more MHs used self-induced vomiting than the other three groups, whereas significantly more MHs and MLs used laxatives than Ns. MHs who had experienced weight-cycling were by far more likely to have unhealthy weight loss behaviors and eating disorders than Ns.
These findings suggest that vigorous exercise in female college students is associated with eating disorder- and weight loss-related concerns/behavior even though the students do not exhibit frequent exercise habits. Though regular exercise is desirable, careful attention must be paid to behavioral factors related to eating and weight loss in exercising female college students.

Background: Epidemiological findings suggest that weight fluctuations are associated with unfavorable health outcomes compared with stable weight. However, the interrelationship between the weight cycling history and dieting status in a non-clinical male trial on the risk for bio-behavioral health is unclear. Objective: The purpose of this study was to examine the relation between weight cycling history as a result of intentional weight loss and bio-behavioral health in Japanese adult males. Method: A cross-sectional study was performed on a group of 146 Japanese working males (47.5±9.3 yr.). Each subject completed a series of self-reported questionnaires in which information about weight cycling history, current dieting practices, life-styles, and social background were assessed. Results of the physical check up were used to assess biological parameters. Self-reported weight cycling was defined as intentionally losing 10% of one's weight and regaining the lost weight. Results: Cyclers reported a significantly greater incidence of current dieting and recent weight gain compared with non-cyclers. Taking regular meals, eating breakfast everyday, and not eating snacks between meals every day were significantly less frequent among cyclers compared with non-cyclers after controlling for BMI. The adjusted odds ratio for AST abnormality was 5.46 (95%CI: 1.08 −27.67), ALT abnormality was 3.31 (95%CI: 1.24−8.78), and γ-GTP was 3.38 (95%CI: 1.07−10.67) among cyclers, compared with non-cyclers. Conclusion: These findings suggest that a history of weight cycling in men, regardless of current weight status, is associated with adverse bio-behavioral health. The risk for several liver enzyme abnormalities associated with weight cycling history was substantial, independent of relative body weight and lifestyle factors.

Previous studies showed associations of sedentary behavior with cardiovascular risks, independent of moderate-to-vigorous physical activity. However, few studies have focused on Japanese workers. This study examined the joint association of television viewing time (TV) and walking time (WT) with overweight/obesity among Japanese municipal office workers. A cross-sectional survey collected height, weight, and time spent in TV and WT from 2,175 Japanese workers, aged 22-62 years-old, by self-administered questionnaire. Participants were classified into four categories according to TV (dichotomized into long (>2 hours/day) and short (≤2 hours/day) by the median) and WT (dichotomized into long (≥30 minutes/day) and short (<30 minutes/day) by 30 minutes/day). Odds ratios (OR) for overweight/obesity (body mass index ≥25kg/m2) were calculated according to the four TV/WT categories, adjusted for potential confounders. Overweight/obesity accounted for 30.5% of men and 15.3% of women. Among men, the adjusted ORs (95% CI) of overweight/obesity were 1.14 (0.76, 1.70) for long TV/long WT, 1.13 (0.77, 1.65) for short TV/short WT, and 0.97 (0.67, 1.42) for short TV/long WT, compared with the reference category (long TV/short WT). Among women, the adjusted ORs (95% CI) were 0.70 (0.39, 1.13) for long TV/long WT, 0.55 (0.33, 0.94) for short TV/short WT, and 0.54 (0.33, 0.89) for short TV/long WT. Spending a long time watching television was associated with a higher risk of being obese in Japanese female municipal office workers, independent of WT. Further studies using prospective designs are warranted to develop an effective weight control program for Japanese workers.

Objective : To translate the Abbreviated Neighborhood Environment Walkability Scale into Japanese (ANEWS-J) and to examine its reliability.Methods : One hundred sixty three community residents (male: 38.7%, age: 21-69 years old) of 600 who were randomly selected from the registry of residential addresses of Taitoh Ward in Tokyo and Fujinomiya City in Shizuoka Prefecture, responded to mail survey including ANEWS-J. Seventy-seven of 163 answered same questionnaire twice with ten days interval to examine the test-retest reliability.The questionnaire was translated into Japanese and fixed through the processes of preliminary test, backtranslation into English and discussion with authors of original version.Intraclass correlation coefficients (ICCs) were calculated for the evaluation of reliability of ANEWS-J.Results : ICCs of the eight subscales of ANEWS-J were residential density; r=0.95 (95% confidence interval; 0.93-0.97), land use mix - diversity; r=0.96 (0.94-0.98), land use mix - access; r=0.90 (0.84-0.94), street connectivity; r=0.83 (0.74-0.90), sidewalk / bike lane; r=0.82 (0.71-0.89), aesthetics; r=0.85 (0.76-0.91), traffic safety; r=0.81 (0.70-0.89), crime safety; r=0.76 (0.62-0.86).Stratified analyses by gender and residential district showed satisfactory reproducibility of the subscales (r=0.63-0.97). Conclusion : Acceptable reliabilities of all eight subscales of ANEWS-J were confirmed in this study.

Background: Perceived benefits and barriers to exercise are important correlates of exercise participation. Purpose: To develop a short version of the perceived benefits and barriers to exercise scale and to examine its validity and reliability. Methods: A population-based cross-sectional study of 865 participants (age: 20-69 years old, men: 46.5%) was conducted in four cities in Japan (Koganei, Tshukuba, Shizuoka, Kagoshima). Perceived benefits and barriers scale including five benefit subscales (physical benefit, psychological benefit, social benefit, weight management, self-improvement) with 10 items, five barrier subscales (discomfort, lack of motivation, lack of time, lack of social support, poor physical environment) with 10 items and stage of change for exercise behavior were assessed by self-administered questionnaire. Results: Confirmatory factor analyses to examine the construct validity revealed acceptable fit indices (benefit scale: GFI=.980, AGFI=.951, RMSEA=.058, AIC=151.669, barrier scale: GFI=.973, AGFI=.949, RMSEA=.060, AIC=166.084). Seven of ten subscales indicated significant linear associations with stage of change for exercise behavior, criterion-related validity was revealed. The reliability of the scale was found to be good as internal consistency and inter-rater reliability. Conclusion: The short version of the perceived benefits and barriers scale developed in this study demonstrated acceptable construct validity, criterion-related validity, internal consistency and inter-rater reliability.

The purpose of this study was to investigate the relationship between physical fitness and coronary risk factor profiles in Japanese women. The subjects were 1, 483 women (ages 30 to 69) who participated in a practical health promotion program. After medical examination, physical fitness was evaluated by conducting a symptom limited maximal exercise test by ergometer to measure maximum oxygen uptake (peakVO2) with an expired gas analyzer. The subjects were classified into 3 groups (high fitness, moderate fitness, and low fitness) according to age and physical fitness level. The results showed that the subjects in higher fitness groups had lower levels in: body mass index (BMI), percentage of body fat, waist−hip ratio, resting blood pressure, and atherogenic index, and higher HDL−cholesterol compared to those in lower fitness group. Even after adjustment for the effects of age and BMI, the subjects in the higher fitness groups had better coronary risk factor profiles. These results suggest that among Japanese women a high level of physical fitness is related to favorable coronary risk factor profiles.

The purpose of this cross-sectional study is to investigate the difference in physical activity among elderly living in different areas in Japan (“Bunkyo Ward in Tokyo” (Bunkyo) and “Fuchu City in Tokyo” (Fuchu) as urban areas, and “Oyama Town in Shizuoka” (Oyama) as a non-urban area). Participants were 1859 community-dwelling residents aged 65-74 years, randomly selected from the residential registry (response rate: 68.9%). A mail survey using self-administered questionnaires was conducted. Multivariate logistic regression analyses were used to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) of various types of physical activity (eg, walking (Walking), going out (Going-out), bicycling (Bicycling), exercise habits (Exercise)), according to residential areas (reference category: Fuchu), stratified by gender, adjusting for socio-demographic variables. There was a significant difference in Going-out (ORs = 0.61 (95% CI: 0.44-0.86) for men, 0.48 (0.33-0.69) for women)), and Bicycling (0.04 (0.03-0.07) for men, 0.04 (0.02-0.07) for women) in Oyama compared to Fuchu. Furthermore, for women, there was a significant difference in Walking (0.56 (0.38-0.81)) and Exercise (0.59 (0.41-0.85)) in Oyama compared to Fuchu. There was a significant difference in Bicycling and Going-out for men in Bunkyo compared to Fuchu, but there was not a significant difference in other items. Low physical activity levels were observed in the elderly in the non-urban area compared to urban areas. The association was stronger in women. Regional difference might need to be taken into account for an effective physical activity intervention.

Introduction: Our palliative care staff began the support activity in opioid introduction for outpatients with cancer at Komaki City Hospital in March 2018, because it was difficult to make them understand about proper use of opioid analgesics and misinterpretation about abuse at the time of opioid introduction in outpatient settings. This study aimed to evaluate the effects of the activity (patient education on pain control, telephone follow up, and assessment of the symptom). Method: Outpatients with cancer receiving strong opioids for pain relief from January 2017 to March 2019 were eligible. We retrospectively investigated the difference of the variables between baseline and after the activity as follows; the ratios of prescribing immediate-release opioids, antiemetics, and laxatives when opioids were prescribed and side effects due to opioid analgesics appeared. Results: The study included 122 patients. The prescribing ratios of immediate-release opioids antiemetics and laxatives all increased from 90.7 to 98.5%, from 63.0 to 70.6%, and from 61.1 to 70.6%, respectively. The side effect incidence due to opioids with STAS-J 2 or more decreased from 12 (22.2%) to 9 (13.2%). Discussion: The activity could contribute to the provision of drug treatments and counselling needed for opioid therapy.
