     View Summary

    We produced the average face by combining forty-one facial images of female college students in order to investigate how the facial impression changes depending on distance between eyes and eyebrows. Furthermore, we produced ten experiment samples by shortening or widening distance between them of the average face in five steps respectively. These images were presented individually to ninety college students, and they were asked to evaluate them using twenty adjective pairs. Consequently, the average face received high evaluations about likability-related impressions, while the faces with shorter distance between eyes and eyebrow got high evaluations about activity-related impressions. Moreover, two principal component (“degree of refinement” and “femininity”) were extracted as a result of principal component analysis to evaluation scores. It was found that degree of refinement was likely to be affected by the perceived size of the eyes, and femininity was defined by distance between eyes and eyebrow.

     View Summary

    Aim. The aim of this investigation was to compare the physical characteristics and somatotypes of 4 Japanese male golfer groups with 2 non-golfer control groups.
    Methods. Sixty-three male golfers, professional golfers (PR, n=11), collegiate golfers (CO, n=24), general amateur golfers (AM, n=13), collegiate recreational golfers (RE, n=15), non-golfing college student (CG, n=45) and a senior population of non-golfers as a control group (SC, n=20), for a total n=128. They were somatotyped, according to the Heath-Carter anthropometric method.
    Results. The results show that the categories of the mean somatotypes of PR (3.8-5.8-1.6), CO (4.7-5.6-2.2), AM (3.3-4.4-2.6) and RE (3.7-4.8-2.7) were endomorphic mesomorph, SC (4.7-3.9-2.1) was mesomorphic endomorph, and CG (3.8-4.3-3.3) was central, respectively. The anthropometric variables that best discriminated between skilled and unskilled golfers were body weight, calf skinfold, calf girth, and femur width, with 82% correctly classified PR and 83% correctly classified for CO. Secondly, combination of sum of 4 skinfolds, biceps girth and humerus width, with 72% correctly classified PR and 75% correctly classified for CO.
    Conclusion. Within the Japanese golfer groups, there are differences between golfers and non-golfers with respect to somatotype, body size and composition. Results suggested that PR showed significantly larger limb girth than other groups. Somatotypes in male golfers tend to increased mesomorphy, related to skill level.

     View Summary

    1. The present study was performed in order to determine the reliablility of the portable calorimeter. 2. Resting energy expenditure (REE) was measured by two different apparatuses: one was the typical gas analyser, the other was the portable calorimeter. 3. Although there are differences among individuals, unless the subject has been exposed to severe physical activity prior to the measurement, a suitable resting time prior to the measurement of resting metabolic rate is 10 min. 4. For the measurement of resting metabolic rate, fluctuations in respiratory quotient (RQ) are extremely small
    there is greater fluctuation due to variations in respiration. Therefore, for the screening of energy consumption, the use of a fixed value for RQ is sufficient when measuring only oxygen uptake. 5. Respiratory fluctuations vary from person to person and it is not possible to make stable measurements in 1 or 2 min. Therefore, a suitable measurement time for resting metabolic rate is from 3 to approximately 6 min. 6. The results indicate that this portable calorimeter is a useful apparatus for measuring REE in the field.

  • Assessment of lower-back muscle fatigue using electromyography, mechanomyography, and near-infrared spectroscopy

    Y Yoshitake, H Ue, M Miyazaki, T Moritani

    EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY   84 ( 3 ) 174 - 179  2001.03  [Refereed]

     View Summary

    We have investigated the etiology of lower-back muscle fatigue using simultaneous recordings of electromyography (EMG), mechanomyography (MMG), and near-infrared spectroscopy (NIRS) in an attempt to shed some light on the electrophysiological, mechanical, and metabolic characteristics, respectively. Eight male subjects performed isometric back extensions at an angle of 15 degrees with reference to the horizontal plane for a period of 60 s. Surface EMG, MMG and NIRS signals were recorded simultaneously from the center of the erector spinae at the level of L3. NIRS was measured to determine the level of muscle blood volume (V) and oxygenation (Oxy-Hb). The root mean square amplitude value (RMS) of the EMG signal was significantly increased at the initial phase of contraction and then fell significantly, while mean power frequency (MPF) of the EMG signal decreased significantly and progressively as a. function of time. There were also significant initial increases in RMS-MMG that were followed by progressive decreases at the end of fatiguing contractions. MPF-MMG remained unchanged. Muscle BV and Oxy-Hb decreased dramatically at the onset of the contraction and then remained almost constant throughout the rest of the contraction. These results, obtained by simultaneous recordings of EMG, MMG, and NIRS, demonstrate that the restriction of blood flow due to high intramuscular mechanical pressure is one of the most important factors in muscle fatigue in the lower-back muscles. In addition, the simultaneous recording system described here can be used to obtain more reliable information regarding the mechanism(s) of lower-back muscle fatigue.

     View Summary

    Stroke-prone spontaneously hypertensive rats (SHRSP) induce spontaneous osteoporosis. To elucidate the specific characteristics of bone metabolism, the SHRSP was compared with age matched Wistar-Kyoto (WKY) rats. We investigated the effects of prolonged swimming exercise training on bone mineral density (BMD) and metabolism in the SHRSP. Seven-week-old male SHRSP and WKY were divided into three groups
    the sedentary control WKY group (n=6, WKY), the sedentary control SHRSP group (n=6, SP) and the swimming exercise training SHRSP group (n=6, SWIM) (in pool with 60 min./day, 5 days/week for 12 weeks). The femoral BMD, bone mineral content (BMC), strength, Ca and P contents (%) of SHRSP were approximately 17, 27, 25, 20 and 9%, respectively, lower than that of WKY (p&lt
    0.001). Serum alkaline phosphatase (AlP) had not changed between both of SP and WKY, but tartrate-resistant acid phosphatase (TrAcP) of SP approximately 3-fold higher than that of WKY (p&lt
    0.05). Both serum calcium (Ca) and intact parathyroid hormone (i-PTH) were similar between SP and WKY. However, serum phosphate (P) of SP was approximately 18% lower than that of WKY (N.S.). These results suggested that SHRSP induces osteopenia by the bone turnover of the promoted osteoclast activity with disturbed phosphate homeostasis. On the other hand, the femoral BMD and strength were approximately 7% and 20%, respectively, decreased in the SWIM (p&lt
    0.001), and femoral bone Ca and P contents (%) were also approximately 11% and 14%, respectively, lower than that of SP (p&lt
    0.001). There were no significant difference between SWIM and SP on serum Ca, but serum P of SWIM was significantly lower than that of SP (p&lt
    0.05). These results suggested that the prolonged swimming exercise training in the SHRSP induces more cruelly hypophosphatemia, and leading to osteopenia eventually. We conclude that SHRSP induces osteopenia with disturbance of phosphate homeostasis, and the prolonged swimming exercise in the SHRSP might deteriorate hypophosphatemia and osteopenia.

  • Thermal regulation in the heat during exercise after caffeine and ephedrine ingestion

    DG Bell, Jacobs, I, TM McLellan, M Miyazaki, CM Sabiston

    AVIATION SPACE AND ENVIRONMENTAL MEDICINE   70 ( 6 ) 583 - 588  1999.06  [Refereed]

     View Summary

    Background: Ingesting a combination of caffeine and ephedrine (C+E) has been shown to raise metabolic heat production and body temperature This side effect of C+E ingestion may be positive during;a cold stress scenario, however, during hear stress it could prove to be detrimental. Thus, the purpose or this study was to clarify the effect of C+E ingestion on body temperature regulation during moderate exercise in a hot dry environment. Methods: Ten, healthy, non heat acclimated, males exercised at 50% Vo(2) peak in a 40 degrees C and 30% RH environment until rectal temperature reached 39.3 degrees C; heart rate (HR) remained at 95% of peak value or greater for 3 min, dizziness or nausea precluded further exercise, or 3 h had elapsed. They did this four times at weekly intervals: familiarization (Fam), control (Cont), placebo, and C+E(5 mg kg(-1) caffeine + 1 mg kg(-1) ephedrine) trials. The Fam and Cent treatments were done first and sequentially while the placebo and C+E treatments were balanced and double-blind. Tolerance times, mean skin temperature (Tsk), rectal temperature (Tre), Vo(2),Vco(2),V-E sweat rate (SR), HR, and sensation of thermal comfort were measured. Results: Tolerance times (mean +/- SD in minutes) were similar for the placebo (120.0 +/- 28.4) and C+E (121.3 +/- 33.9) trials and both times were significantly longer than Cont(106.6 +/- 24.0) trial. C+E did not affect Tsk, initial Tre, Delta Tie, SR or the sensation of thermal comfort. Vo(2) and V-E were significantly increased by C+E. HR was elevated by C+E compared with the other trials, but only during the initial 20 min of exercise. Conclusion: Although the metabolic rate was slightly increased with C+E treatment, it was sufficiently offset by increased heat loss mechanisms so that internal body temperature was not increased during moderate exercise in a hot, dry environment.

     View Summary

    The local exposure of cold has been used to decrease spasticity and facilitate neuromuscular function. This study analyzed the change in the excitation of the motor neuron pool, which was indicated by the amplitude of the H reflex measured in lower limb muscles when the skin temperature was lowered in different cooling area. The subjects were seven healthy males. A series of H and M wave were recorded via surface electromyogram electrodes before cooling and during cooling of the soleus muscle. The skin temperature was lowered in average from 33.1℃ to 22℃ subsequently. In all cases, the amplitude of the H wave increased in response to cooling. It was concluded that different exposure areas did not affect H reflex during localized muscular cooling.

     View Summary

    In the last few years, epidemiological studies have shown correlations between the low endurance capacity of the erector spinae muscle and low back pain (LBP). In this study, the function of the erector spinae muscle and localized muscle fatigue in LBP were investigated in both LBP patients and control subjects without LBP, using surface multi-channel electromyograms (EMG). Four positions (L1, L2, L4, L5) were chosen as representative locations for the different functions of the erector spinae muscle. Median frequency (f(m)) parameters of an EMG power density spectrum were monitored to quantify localized muscle fatigue. This research indicated a statistically significant difference (P < 0.05) in f(m) parameters between the LBP patients and the control subjects. The integrated electromyogram (iEMG) signals of LBP patients were considerably higher than for the control subjects during endurance isometric contraction. Our research suggested that human fatiguing erector spinae muscle, in submaximal voluntary contractions tests, induced a different firing order of motor unit spikes between two groups.

     View Summary

    GPS is funded by and controlled by the U.S.Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U.S. military. GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time.Four GPS satellite signals are used to compute positions in three dimensions and the time offset in the receiver clock. We already have been studied to use this Global Positioning System in applying to Physical Activity. Estimation of moving distance is to get accuracyusing handy GPS receiver And with Doubly Labeled Water method. Human movement activity was analyzed. Validation against the precise and near continuous respiratory gas exchange has demonstrated that the method is accurate(1〜3%)and has a precision of 4% to 7%, depending isotope dose, length of elimination period, and frequency of sampling(two-point vs. multipoint). The method is based on a number assumptions that must be taken into account depending on the application of human activity. There is still some debate on refinement of the kinetic model. And we can consider the DLW method the gold standard for assessing energy expenditure

  • Development of Falling Self-Efficacy Scale for Elderly People : the Reliability and Validity

    Japan Society for the Promotion of Science  Grants-in-Aid for Scientific Research

    Project Year :



     View Summary

    This paper outlines the development of the falling self-efficacy (FSE) scale for elderly people. From interviews with 24 elderly people who lived in a home for the aged, 27 items were selected as indicators of fall events or fall related situations during daily life activities in Study 1. These items were applied to 151 elderly people who lived in community area and nursing homes to develop the scale in Study 2. Finally, the 15-items FSE scale was developed after checking the distribution for each item. The scale showed high reliability by the internal consistency (α =.96) and the test-retest procedure (γ=.74) in Study 3. In Study 4, the validity was examined by finding the relationships between the FSE score and some movement variables for 10 m walking and stepping-over the 30 cm obstacle. The FSE score was significantly correlated to the stridelength and velocity during walking, as well as the stride distance and velocity in stepping-over. Fallers during last year also had a significantly smaller FSE score compared to non-fallers. In addition, persons who had high fear of falling showed a significantly smaller FSE score. For future research, the scale should be used to screen the elderly persons who have a severe fear of falling and lead to restricting physical activity and to clarify the effects of the fall prevention program. Finally, it was discussed that cognitive-behavioral approach plays an important role for effective fall-prevention programs for elderly people

     View Summary

    Health・fitness of aged man were designed quantitatively as performance and activities at daily livehood. At their lifestyle, the exercise prescription was positioned as the measures of the health-fitness promotion and keepness. Those exercise prescription would effect upon the trainability of muscle contractive components and the recruiment of motor units, then their muscle force and non-fatigue performance (the whole endurance) were recorded on various parameters of muscle reflex and responses, muscle torque, electromyography (EMG), evoked EGM (H and M waves), muscle endurance, muscle regulation of the lower limb balance and physical stress during exercise prescription.Method of this study were electromyogram and evoked EMG of various body parts during exercise of aged man. Aged man muscles were observed little atrophy and denervation on various body tremities and motor nerves. Also, slow-twitch oxidative muscle fibers (SO) were appeared at the triceps surae and the quadriceps femur except the posture-gravity muscles. Recruitment of motor units of aged man were characterized on the slower frequency and the lower amplitude of EMG signals during physical exercise. While fast type of motor units were not appeared at whole body muscles, and those moter nerve innervation toward the muscle did not change on the number ratio of the motor nerve and muscle fiber at the aged man

     View Summary

    Short distance athletes has developed their leg flexor's hyperptophy and showed their skillful performance depended upon remarkable development on the Hamstring muscle of the knee extension. Exercise hormone (catecholamine and beta-endorphin) was measured at resting, during sports practice and at recovery, and distinct values of athletes playrs showed much more increase than that of sedentary quantitatively. The more volume of Dopamine were appeared at resting, the lesser fit for sports playrs or athletes during exercise. While long distance athletes and whole endurance sports playrs (soccer and basketball) showed an averaged 58.0 ml/kg/min of maximum oxygen uptake, and then their training programs has been recommended an classical aerobic exercises, for example an interval training or a circuit training of seven items. Physical character of athletes playrs has been a non-vagotonia, a sympathetic nerves, and little fluctuation on R-R interval of their electrocardiogram at resting.Ramp loads programs were developed as a training modes for sports athletes depended on their relationship between physical characters and sports performance. These loads program would be used in order to discover the elite playr in future, and to select the most adaptive sports items in various sports

     View Summary

    本年度は携帯型GPSレシ-バを使用して、携帯電話による補正位置情報サービスによる補正された位置情報を取得した。この取得された位置情報を基にSISという地図情報システム(Geographic Information System)にその位置データを基にした移動軌跡図を描いた。また、同時に生体情報(心拍数、呼吸数、節電図)も携帯型データレコーダによって取得した。位置情報は携帯電話を利用しているため電波を受信できない状況(例えば地下など)も生じてくるが、精度の高い位置データの取得が可能であった。このことにより、二次元的及び三次元的な人の移動距離の実測が可能となった。また、同時に取得した生体情報は人の移動距離の生体の状況を説明できるものとして有用なことが示された。今後は、位置情報のデータ・生体情報をオンライン化することや位置情報の補正サービスを受けた際のデータの補間法などがいくつかの点での問題が残された

  • ヘリウム混合ガス圧暴露によって生じる運動麻痺への再圧の効果について


     View Summary

    本研究は,きわめて短い時間の高圧曝露にヘリウム混合ガスを用いたときの再圧の影響を見たものである。 実験方法は,Wister系雄ラットを小型動物用高圧タンクに入れ,ヘリウム酸素混合ガスで7ATAまで急速加圧し,20分間保圧した後,毎分20atmの速さで1ATA(大気圧)まで減圧した。ヘリオックス圧曝露からの減圧終了10分後,ラットを高圧タンクから取り出し生死を確認した。そして,ヘリオックス圧曝露からの減圧終了後15分から20分間,3ATAの空気再圧をおこなった。 3ATAにて20分間の空気再圧を行った実験では,12例中6例が両後肢麻痺,4例が起立できない状態であった。また,残りの2例では,異常動作はみられなかった。 空気再圧後4例が死亡したが,いずれも再圧前は,両後肢麻痺の状態であり,再圧中は症状に変化はなかった。このうち2例は,再圧を終了し,1ATAに戻った直後,激しく喘ぎ,死亡した。精巣上体付随の脂肪組織では,血管外気泡と共に大量の気泡がみられた。 再圧治療が効果をあげるには,症状がなくなるまで気泡を縮小させるばかりでなく,その後の減圧で気泡が拡大して再び減圧症が引き起こされたり,途中の経過で新たな気泡が形成されないことが必要とされている。 不完全な再圧では,気泡が吸収消失せず溶解窒素量が増加すること,また再圧中に縮小した静脈中の気泡が動脈側へと移動し,減圧中に動脈側で再度大きくなり,より重篤な症状を引き起こすことなども減圧症の悪化や再発の要因として挙げられる。
