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.

既存の最大酸素摂取量 (VO2max) の判定基準は軍人やスポーツ選手など十分に身体鍛錬を積んだ者を対象に設定された.しかし, 現在VO2maxは健康関連体力要素の1つとして, 幼若者から高年齢者に到るまで広く普及している.従って, それらの者に適用できるVO2max判定基準およびその臨界値が求められる.本研究では, 8~82歳までの健康男女548名を対象に, トレッドミルによる負荷漸増運動を課し任意の最大酸素摂取量 (VO2max) を実測した.任意のVO2max値を年齢回帰させ, 年齢予測VO2max値を算出し, 実測VO2max×100/年齢予測VO2maxの式から%VO2max値を求め, その度数分布図に反復切断法を適用し, VO2max基準域 (X-1.96SD~X+1.96SD, 70%~130%VO2max) を設定した.この範囲の平均値をVO2max基準値, 下位10%に相当する値を臨界値とし, いずれも実測値に変換し5歳毎の平均値として男女別に提示した.次いで, 70%~130%VO2max範囲の生理・生化学的指標 (HRmax, DPmax, RRmax, %△PVmaxおよびbLAmax) を, %VO2max値算出法に基づき%表示した.%表示された各指標の度数分布図の下位10%に相当する値を, VO2max値として採択し得る限界値 (臨界値) とし, 実測値に変換し5歳毎の平均値として男女別に提示した.最後に70%VO2max以上の領域を占めた各被験者の値をVO2maxと認定 (男性224名, 女性283名) し, 各生理・生化学的指標の臨界値を単独または組み合わせ適用によるVO2maxの採択率を調べ, さらに簡便・容易性および信頼性の観点からVO2max判定指標およびそれらの組み合わせを吟味した.その結果, 単独適用した場合の採択率が最も高いのはHRmaxであり, 男性の臨界値92.1%, 女性の値91.0%HRmaxを適用し, それぞれ92.9%および91.2%の採択率が示された.次いで, 簡便・容易で信憑性の高い組み合わせは, HRmaxとbLAmaxの両方の臨界値を同時に満たした場合で, 男性では82.6%, 女性は80.6%の採択率であった.本研究によって, 反復切断法と従来の判定基準適用によるVO2max値との間に有意差のないことが確認され, 反復切断法による性・年齢別VO2maxの基準値および臨界値が提示された.さらに, 簡便で信憑性の高いVO2max判定指標としてHRmaxおよびbLAmaxの臨界値が提示され, 性・年齢別臨界値の適用が奨められた.

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.
