The present study aimed to examine the effects of Internet addiction on daily steps. A cross-sectional study was performed at the Osaka Institute of Technology. A total of 334 male college freshmen were analyzed. The participants were assigned to five groups according to Internet addiction levels. Internet addiction levels were assessed by Diagnostic Questionnaire, which has been reported by Young (1998), and we measured daily steps of the participants using a pedometer during usual 1 week. There were no significant trends or differences among five groups in physical characteristics of the participants, sleep duration, frequency of eating breakfast, and walking during commute time. However, with the level of Internet addiction increasing, daily steps showed a statistically significant decreasing trend. Therefore, Internet addiction levels might be related to reductions in steps in a dose-response manner. To clarify this point, further investigations will be required after considering confounding factors.

The present study was aimed to investigate the physical ability of javelin throwers among uni-versity students using the magnetic resonance imaging (MRI), and Capacity Test, compared with other throwers.The anatomical cross-sectional areas (ACCAs) of trunk muscles were determined using MRI. Capacity Test is composed of 30 m sprint, standing triple jump from a double-legged, backward over the head shot, forward over the head shot, sargent jump, snatch, and shoulder flexibility test with a javelin.Results are as follows:1. The male javelin throwers (MJT) group showed significant correlation between javelin throw records and ASCAs per body mass of body trunk extensor muscles (r=0.722, p<0.05) .2. There was significant correlation between the forward over the head shot, and javelin throw in MJT group (r=0.800, p<0.01) . And the same tendency was also seen in female javelin throwers (FJT) group (r=0.735, p=0.055) .3. The MJT group showed some correlation between javelin throw records and ASCAs per body mass of psoas major muscle (r=0.657, p=0.060) .By the above-mentioned results, it was considered that the trunk extensors are important for male javelin throwers.

The purpose of this study was to retrospectively examine the association of habitual exercise with “single fall (= 1)”, “multiple falls (≥ 2)”, and “injurious falls (≥ 1)” among community-dwelling older adults. A total of 1,683 community-dwelling older adults, aged 60-97 years (72.6 +/- 6.6 yr, 512 men and 1,171 women) were included in this study. Habitual exercises continued one year or longer (6.4 +/- 9.5 yr) were classified into twelve types. Exercise components (time, quantity, period of continuity, and number of exercises) were divided with median or tertiles. To assess the association between habitual exercises and fall status, multivariable logistic regression analyses with stepwise selection method, were applied. The multivariable logistic regression analyses showed that dance (odds ratio (OR): 0.30, 95% confidence interval (CI): 0.09-0.96) was negatively associated with “single fall”. Bicycling (OR: 3.72, 95% CI: 1.32-10.77) was positively associated with “multiple falls”, and the period of continuity (OR: 0.74, 95% CI: 0.60-0.91) was negatively associated with “multiple falls”. None of the exercise components were selected with regard to “injurious falls”. Results indicate that dance may be an effective type of exercise for fall prevention among community-dwelling older adults. However, caution about falling is warranted toward bicycling as an exercise. Moreover, a longer period of continuity (≥ 4 years) appears to be a positive factor of habitual exercise for fall prevention.

The purpose of the present investigation was to examine the relationships between the exercise history and the bone mineral density (BMD) and bone mineral content (BMC) in female Japanese young adults using dual X-ray absorptiometry (DXA). One-hundred twenty females, aged between 18 to 28 years, participated in the present investigation. The BMD at the lumbar spine (L-BMD), whole body BMD and BMC (WB-BMD and WB-BMC), lean body mass (LBM) and fat mass (FM) were measured by DXA. Using a self-administrered questionnaire, the exercise habits during preschool (4-6 years), primary school (7-12 years), junior high school (13-15 years), high school (16-18 years), and the current habits (>18 years) were eveluated. The L-BMD, WB-BMD and WB-BMC were significantly higher in the subjects with exercise habits during both the period of <18 years and >18 years compared with those in the subjects without an exercise history during all periods (p<0.05). In a separate analysis with the data stratified by the school age, the subjects with an exercise history during primary school, junior high school, or high school had significantly higher BMD and BMC values compared with the non-exercisers (each, p<0.05). In contrast, the BMD and BMC did not differ significantly according to either the exercise history during pre-school nor the current exercise status. A multiple stepwise regression analysis revealed that the body weight, LBM, FM, age of menarche, and exercise habits during high school were significant determinants of the L-BMD, WB-BMD and WB-BMC (p<0.001). The results of the present investigation show that both the exercise history during school age and the current exercise habits affect the BMD and BMC in young adults. In particular, high school females should be encouraged to participate in the regular exercise to increase their bone health. Future studies will be needed to confirm the targeted age-group(s) for participation in sports/exercise for the improvement of bone health, including an analysis of the type and intensity of exercise/sports.

Several studies have shown that low cardiorespiratory fitness (CRF) or heavy alcohol consumption is risks of total or certain types of cancer death. However, the combined influence of CRF and drinking habits on total cancer mortality is not clear. The purpose of this study was to investigate the joint effect of CRF and drinking habits on total cancer mortality among Japanese men. We evaluated the CRF and drinking habits on risk of total cancer mortality in 8,760 Japanese men (age: 19-59 yr) who were given a submaximal exercise test, a medical examination test, and questionnaires on their health habits. CRF was measured using a cycle ergometer test, and the men were classified into two categories by CRF levels based on the reference value of CRF (R-CRF) in “Physical Activity Reference for Health Promotion 2013” (Under R-CRF and Over R-CRF). Also, the men were assigned to Non Drinking, Moderate Drinking, and Heavy Drinking categories. There were 178 cancer deaths during the 20-yr follow-up period. Relative risk and 95% confidence intervals for total cancer mortality were obtained using the Cox proportional hazards model while adjusting for age, body mass index, systolic blood pressure, and smoking habits. Using the Under R-CRF & Heavy Drinking group as reference, the relative risk and 95% confidence intervals were 0.37 (0.16–0.85) for the Over R-CRF & Non Drinking group. This result suggests that Japanese male with a high CRF and a low drinking habit have a lower risk of total cancer mortality.

水中での作業であるが身体を冷しても作業後の採暖を行うので月経及び妊娠にはあまり影響がない。又早流産が少くなつたのは保健知織と公衆衛生施策の普及による成果であると思われる。分娩については水泳と云う全身運動が産婦体操の役目をしているように思われる分娩時間も短くしかも大部分が軽産である。産褥期間は21日で他の職業となんら変りはない。出生時の新生児の体重も変りはないが舳倉島海女の平均7.4人の出生数は多産であるが育児に関する関心が薄いと思われるのは50才以上の海女の子供の死亡率が49.1%と半数が死亡している事でもわかることであるがそれも消化不良とか栄養不良症であると云う。海女の年令が若いほど子供の死亡率が減少していると云う事は保健知識と育児知識が行きわたりつつある為とも云える。以上の事から海女業は婦人の生理に対して影響は少ない様に思われる。

Purpose: The purpose of this study was to determine whether the impact on the body during landing in dancers is less than in non-dancers by using accelerometers and motion analyzer.Method: Eleven ballet dancers and 11 non-dancers participated in this study. Each subject was instructed to perform 3 types of landing from a height of 30cm: landing, silent landing and raise up landing. Markers were put on the iliac crest, greater trochanter, knee joint, lateral malleolus. The peak vertical and horizontal accelerations of the lumbar, peak vertical acceleration of the greater trochanter and the peak flexion angles of the hip and knee joints were measured after the trials.Result: In the raise up landing, the peak vertical acceleration of the lumbar region in dancers was less than that in non-dancers (p < 0.01), and the peak knee-flexion angle in dancers was greater than that in non-dancers (p < 0.01). There were no differences between the peak hipflexion angles of dancers and non-dancers.Conclusion: The impact on the lumbar during raise up landing was less in dancers. In raise up landing, the trunk tends to be fixed when the dancer stands upright. Moreover, dancers attenuated the shock to the lumbar region by increasing the knee-flexion angle to a greater extent than the non-dancers did. This result may indicate the importance of the knee joint flexion in attenuating the shock during landing and show that dancers excel in using their knees flexibly.

In order to clarify the relationship between acute physical exercise and immunity, the numbers of overall leucocytes, lymphocytes and neutrophils, the concentrations of immunoglo-bulins and complements, the ratios of lymphocyte subsets (OKT 3, 4, 8, Leu 7, OKIa 1) and the levels of lymphocyte transformation response to PHA were measured in nine untrained male subjects (18-22 years old) before, immediately after, along with 24 and 72 hours after acute physical exercise at 50% of VO2max for 2 hours. Before exercise all components were within normal range. Exercise produced a significant rise in the number of leucocytes and neutrophils overall. The response of lymphocytes to PHA immediately after exercise was significantly lower than before, or 24 hours or 72 hours after exercise.There was no change in the number of lymphocytes, or in the concentration of immunoglo-bulins and complements before and after exercise. Likewise the ratios of lymphocyte subsets also remained unchanged.From these results, it can be concluded that acute physical exercise by untrained subjects is one kind of physical stressor and can contribute to T cell dysfunction.
