加速度脈波と血圧の関係および加速度脈波の各波の生理的な意義を明らかにすることを目的として, 男子学生5名を対象に, 上腕圧迫によって末稍血流が変化する際の指尖容積脈波, その二次微分波および指動脈圧波をbeat-by-beatに測定した.得られた結果は以下の通りであった.1.収縮期血圧の上昇によって加速度脈波のa波は上昇し, bおよびe波は下降するのに対して, 拡張期血圧の増大によってa波は下降し, bおよびe波は上昇する傾向にあった.また加速度脈波は細動脈弾性率によっても大きな影響を受け, 弾性率がノ1丶さいほどa波は上昇し, bおよびe波は下降する傾向にあった.2.加速度脈波のcおよびd波は収縮期血圧の上昇によって下降し, 拡張期血圧および細動脈弾性率の増大によって上昇する傾向があるが, それらの3要因では十分に説明できず, ほかに影響をおよぼす要因の存在が示唆された.3.収縮期血圧が上昇する場合でも, それが血流量の増加に起因する場合には加速度脈波の波形パターンはG→Aに変化するのに対し, それが末梢抵抗の増加に起因する場合にはA→Gに変化するものと考えられた.これらの結果から加速度脈波と血圧の関係は単純でなく, 血圧構成因子である血流量や末梢抵抗によって大きく影響される.したがって加速度脈波と血圧を併せて測定することが末稍循環状態をより正しく評価する上で有効であると考えられる.

The purpose of this study was to determine the differences in the growth patterns of the external oblique (EO), internal oblique (IO), and transversus abdominis (TrA) muscles in adolescence baseball players. The subjects were 17 elementary school students (ES), 56 junior high school students (JS), and 21 high school students (HS) who played baseball. The EO, IO, and TrA muscle thicknesses were imaged using an ultrasound imaging device and analyzed separately on the dominant and non-dominant sides. Curve regression estimation of the relationship between EO, IO, and TrA and chronological age was used to read inflection points. An analysis of covariance was also performed, using body weight as a covariate for comparison with each of the EO, IO, and TrA grades. The inflection point readings showed that TrA was 11.26 years old (p<0.01, R2=0.45) for the dominant side and 10.10 years old (p<0.01, R2=0.46) for the non-dominant side, earlier than the inflection points of EO and IO. Analysis of covariance showed no significant difference in EO between any of the grades. IO showed significantly higher values for muscle thickness as the grade increased, both on the dominant and non-dominant side. TrA was higher for JS among ES and JS and higher for HS among ES and HS on both the dominant and non-dominant sides. EO may growth with increasing body size, while IO is interpreted to increase with increasing age due to the movement of baseball. TrA may grow earlier than EO and IO.

Exercise performance may be improved by listening to high-tempo and motivational music prior to exercise. However, the effects of the combination of “tempo” and “motivational factors other than tempo” of music on exercise performance have not been examined in detail. We examined whether listening to music before exercise affects repetitive sprint performance and psychological responses in healthy young men. Twenty-one healthy men performed two consecutive sets of 20-second sprint cycling with a 120-second rest period between sets. Five types of music were used during the warm-up and rest periods: no music (Con), high-tempo music that subjects judged to be motivating (MH, 130~140 bpm), high-tempo music that subjects judged to be unmotivating (UMH, 130~140 bpm), low-tempo music that subjects judged to be motivating (ML, 70~80 bpm), and low-tempo music that judged to be unmotivating (UML, 70~80 bpm). Motivation, pleasure-displeasure and arousal-sleepiness, and rate of perceived exertion were investigated using a questionnaire. The maximum power per body weight during sprint cycling was significantly higher in ML than in Con, and MH tended to be higher than in Con. Motivation increased significantly from “After Warm-up” to “After Recovery” for MH and ML, but did not change significantly for Con, UMH, and UML. These results suggest that listening to motivational music, regardless of tempo, improves the maximum power of sprint cycling.

In mammals, the circadian rhythms have been shown to regulate several physiological functions, including body temperature, sleep-wake behavior, physical activity, hormonal secretions, and metabolism. These processes are controlled by circadian clock genes, and abnormal circadian rhythms are associated with the development of obesity, diabetes, and lifestyle-related diseases. In addition, the timing of behaviors such as food intake, exercise, and stress influence circadian rhythms, including clock gene expression in peripheral tissues. Therefore, the interaction between nutrition and the circadian clock is so-called “chrono-nutrition” is poised to become an important research field of chronobiology. In this review, we review the effects of a timed-nutrition on circadian clocks and their timing-dependent effects on physiological functions.

In this study, we investigated the relationship of an osteoarthritis of the knee (OA) and a knee pain of single-leg on the bilateral difference of ground reaction force in stepping. The subjects were 29 middle-aged women (mean age 63.7±6.7 years). We categorized them into groups based on the following conditions: osteoarthritis of the knee (OA groups; n = 9), knee pain (KP groups; n = 7), and no pain (NP groups; n = 13). We measured the ground reaction force in a vertical direction when stepping on a platform. The evaluation variables were as follows: peak of ground reaction force at the early stance phase (F1), middle phase (F2), and late phase (F3). We calculated the bilateral difference of ground reaction force of the left and right leg and the affected side and the unaffected side ratio. The result of two way ANOVA, there was a significant difference between the leg in F1 and F3 and the group at F2. The result of comparison between the OA groups and the KP groups, there was no significant difference in the unaffected side and the affected side ratio, those in the OA groups tended to have a load on the unaffected side, while those in the KP groups had a load on the affected side. Therefore, it was suggested that there was the relationship of the OA and a knee pain of single-leg on the bilateral difference of ground reaction force in stepping.

A study was conducted to determine non-invasively the effects of endurance training on the size of the inferior vena cava in humans. Twelve healthy male subjects were assigned to either an exercise-trained group (ET, n=7) or a sedentary control group (S, n=5) . The ET group underwent cycle-endurance training for 8 weeks (80%Vo2max, 40 min/day, 4 days/week) . The S group led normal lives during the 8-week period. Before and after the training period, cross-sectional areas (CSA) of the inferior vena cava and the ascending and abdominal aorta were measured by echography. The CSA of the inferior vena cava after training was significantly larger than that before training in the ET group. There was no significant difference in the S group. These results indicate that the inferior versa cava can be morphologically altered as an adaptive response to endurance training. We consider that this adaptation partly contributes to the improvement in the efficiency of venous return from exercising muscles to the heart. Although the present training also increased the CSA of the aorta, the degree of change was smaller than that seen in the inferior vena cava, implying that the factors of adaptation and adaptability to endurance training in the inferior vena cava differ from those in the aorta.

Insufficient physical function is strongly associated with decreased activity of daily living and health-related quality of life in middle-aged and older women. YOSAKOI Soran is one of the traditional Japanese dances to have naruko (wooden hand clappers) in their hands as they dance and incorporate the phrase from the Soran Bushi in their song. YOSAKOI Soran festivals can be seen being held in various places across the country, proving its growing popularity with residents as a celebration regardless of age or occupation. The purpose of this study was to examine the cross-sectional associations between YOSAKOI Soran and the physical functions of middle-aged and older women. A total of 30 middle-aged and older women practicing YOSAKOI Soran (YOSAKOI group) and 163 middle-aged and older women who had not practiced YOSAKOI Soran (control group) participated in this cross-sectional study. Handgrip strength, 30-second chair stand performance, and flexibility were used to measure physical functions. Handgrip strength was not significantly differed between the YOSAKOI group and the control group (P = 0.79). 30-second chair stand performance and flexibility were significantly higher in the YOSAKOI group than in the control group (both P < 0.05). These results remained significant after adjusting for age and body mass index (both P < 0.05). The present results suggest that practicing YOSAKOI Soran may increase lower extremity function and flexibility in middle-aged and older women.

In order to establish a health promotion program for Taiyo Village in Ibaragi Prefecture, we initiated a research project at University of Tsukuba in 1996. The purpose of this research project are as follows : 1) Examine health promotion in the independent elderly, who make up the majority of the elderly population ; 2) Develop measures to prevent strokes, falls and fractures, which account for about half of the cases in which the elderly become bedridden ; 3) Establish a safe and effective exercise program according to scientifically proven health guidelines ; 4) Assess the efficacy of strength training, which has not been incorporated into most elderly exercise programs, in preventing the elderly from becoming bedridden due to falls and fractures ; 5) Develop a program that can be easily adapted by different municipalities ; and 6) Accumulate success stories at Taiyo Village and disseminate them throughout Japan. The results of this 7-year Taiyo Village project have yielded several important points: 1) Establishment of guidelines to improve life functions; 2) Development of an exercise program to improve and maintain functional ability for life ; and 3) Reduction in medical costs. The results of the present study suggest that when promoting the health of the elderly, it is important to not only study the efficacy of an exercise program, but to also establish a regional program that effectively utilizes research findings.

Whether or not f ractural accidents have increased in children cannot be determined only by the statistical data. Fracture may be related to various factors and among them, the protective buffer effect by muscle is one of the most important factors. To clarify the onset process of fracture in the forearm in children which was observed most frequently, experimental studies have been done using a model for the forearm bones made of resin and the forearm samples of cadaver. Stresses of various parts of the bones were measured by the strain gage method, and the following results were obtained.Under static load bearing, the model presented the stress distribution depending on the form, and the largest stress was obserbed at the distal diaphysis of the model of radius. The stress distribution of forearm sample under static load bearing was greatly influenced by the articular capsule and the distal region of the radius showed the maximum stress. As the model was gradually filled up simulating muscular action, the stresses decreased. When the traction force of the muscle was simulated by the use of a steel wire, the stress distribution depending on the form changed and the stresses reduced. As the muscular action was gradually added to the model, fracture was not apt to occur and then, greater impulsive force was required for the onset of the event in impact load test.Based on the above results, it is suggested that, if the protective buffer effect by the nerve and muscle acted incoordinately when a child falls down, the greater stress is loaded to the bone tissues, resulting easily in fracture.

Strenuous and consecutive exercise results in fatigue symptoms accompanied decrease in salivary secretory immunoglobulin A (sIgA) in athletes. On the other hand, it has been reported that plasma taurine concentration was increased after the high intensity exercise. However, change in salivary taurine concentration after strenuous and consecutive exercise is unknown. The purpose of this study was to investigate the relationship between fatigue symptoms and changes in salivary taurine concentration in collegiate male soccer players. Thirty seven collegiate male soccer players participated in three consecutive days of match program. To detect of fatigued players, we measured awakening heart rate and body weight. As the results of these two measurements, we divided subjects to two groups (non-fatigue group, n=15; fatigue group, n=22). We also measured salivary sIgA and taurine concentrations before and after program. Before the program, there were no significant differences in any parameters between two groups. Salivary flow rate and sIgA secretion rate were significantly decreased after the program in the fatigue group. Furthermore, salivary taurine concentration was significantly increased after the program in the fatigue group. In the non-fatigue group, there were no significant differences in any parameters during program. Our results indicated that salivary taurine concentration increased after consecutive high-intense exercise in the collegiate male soccer players.

Previous study reported that baseball pitchers had a decreased shoulder internal rotation (IR) range of motion after pitching. However, whether the decreased range of motion associated with pitching is caused by tightness of the posterior shoulder has not been clarified yet. The joint stiffness in the passive torque can be compared with posterior shoulder tightness before and after pitching. Hence, this study aimed to compare shoulder IR stiffness based on passive torque before and after pitching in baseball pitcher. Eleven health male collage baseball pitchers were recruited. Passive torque during IR (max IR, peak torque and stiffness) of dominant and non-dominant arms was measured using an isokinetic dynamometer. Measurements were taken before, after, and post 24 hours after pitching (105 pitches). It was observed that after pitching, max IR and peak torque were significantly decreased compared to those before pitching. However, there was no difference in the stiffness of passive torque among three measurements. In conclusion, healthy college baseball pitchers have a decreased IR range of motion after pitching. However, this result is not due to posterior shoulder tissue tightness, but because of altered stretch tolerance.

Single-tooth sandals under new development have special material and shape characteristics. Exercises with single-tooth sandals can increase pressing stimulus on the soles of the feet, thereby suppressing a decline in medial longitudinal arch and elevating sole surface temperature. This study thus aimed to examine the effects of exercise with single-tooth sandals on medial longitudinal arch and sole surface temperature. Sixteen young adults (23 ± 5 years) participated in 20 min of stepping exercise on the spot. They randomly put on a regular normal sandal (N conditions) or a single-tooth sandal (Z conditions) on each left and right side. Before and after exercise, medial longitudinal arch and sole surface temperature were assessed by digital caliper and straightedge and thermography, respectively. No significant differences in baseline parameters were observed between N and Z conditions. After exercise, arch height and arch height ratio significantly reduced in N conditions, but not in Z conditions. Central sole surface temperature in Z conditions also increased significantly, and the changes in surface temperature were significantly higher in Z conditions than in N conditions. Therefore, these findings suggest that exercise with single-tooth sandals has a positive effect on a suppressing decline in medial longitudinal arch and an elevation in sole surface temperature.
