ジャーナル フリーIn this paper, it was aimed to establish a multiple regression equation to predict total body water (TBW) from several anthropometric measurement.
Total body water was determined by the analysis of the dilution of orally ingested deuterium oxide (D2O) in urine of 27 Japanese females in 20-39 yrs. old, who vol-unteerly participated in this experiment.
The anthropometric measurements were taken for each subject on standing height, body weight and a total of 8 body sites, including 4 skinfold thickness, 2 diameters, and 2 circumferences of limbs on the same day.
The method of forward stepwise regression analysis was adopted to establish the regression equation. The rule of stopping to select the variables was F-statistics (F enter=1.8, F remove=1.7) .
The results obtained were as follows.
1) The mean value of TBW was 25.3 (l), which was less than the value of the American adolescent males reported by Schutte (1980) .
2) Entered variables in this equation were body weight (WT), femur breadth (B1), humerus breadth (B2), abdomen skinfold thickness (S4) and the other variables contributed little.
3) The regression equation obtained were as follows. y=8.70+0.189xWT+1.79xB2-0.092xS4+1.84xB1
4) The multiple correlation coefficient and standard error of estimates of this regression equation were 0.908, 1.271 (l), respectively.
5) An analysis of residuals by means of plotting of standardized residuals and predicted value showed that the defficiency of this equation was little recognized.
We must pay most effort to establish the predictve equation on the samples which have been selected from populations defined on the basis of factors such as age, sex, or race alone or in combination.抄録全体を表示PDF形式でダウンロード (1143K) -

ジャーナル フリーA system for making prolonged measurements of oxygen uptake without the use of mask or mouthpiece is described. A subject wears a hood through which air is drawn by a exhaust pump located on the end of hoses. The flow rate of main stream is measured by a pulsed wire flowmeter located between flexible hose and rigid hose. The flow rate is essentially constant during a run. One sample pump bypasses small amount of mixed air from the main stream. The other pump draws the room air. Two sample pumps operate alternatively at 2 min interval. The sample gas is dried by passing through molecular sieve desiccant and is delivered to in-line oxygen analyzer. Both signals of flow rate and oxygen concentrations of room air and mixed air are converted to digital quantities and then stores in memory devices at 5 min interval. All measuring devices were assembled to small package which the subject carries on his back. The weight was about 7 kg. The memory chip is removed from the device after experiment and oxygen uptake is estimated by connecting the memory chip to a microcomputer. This measurement compared favorably with measurement with Douglas bag collection and gas analysis.抄録全体を表示PDF形式でダウンロード (2502K) -

ジャーナル フリーIn order to obtain the physiological information during such outdoor exercises as cross-country running or skiing, mountain climbing or diving in the sea water etc, we developed a new device employing MEMORY IC. for monitoring and recording various biological information from the subjects during exercise with no restraint. The device is composed of detecting, data processing and recording units. The application of a semiconductor, CMOS MEMORY I.C. to the recording unit enabled us to construct the instrument, which is very compact (150g) and tolerant to the mechanical vibrations as well as the enviromental disturbances. The recorded data are read out by a microcomputor system. This device was applied to ten subjects during running, where the heart rate, respiration rate and body temperature were recorded. They covered a distance of 9 km within 60 minutes. The heart rate of five trained men was stabilized at nearly fixed level during running which was consistent results with those by the treadmill, but in the untrained men different results were shown from the trained. The heart rate of the untrained men showed that they encoutered the limits of the capacity on the way of running. These results showed wide applicability of this device for the physiological analysis of outdoor exercises.抄録全体を表示PDF形式でダウンロード (2595K) -

ジャーナル フリー1.最大筋力の5, 10, 20, 30%の負荷を用いて前腕の律動的作業を行わせた時の作業中と回復期の血流量を静脈阻止プレチスモグラフ法を用いて連続的に測定した。
2.最大筋力の5%の負荷で得られた律動的作業中の血流量は, 3分間の作業中に定常状態になる傾向がみられた。
3.最大筋力の10%の負荷で得られた作業中の血流量は, 作業開始後約1分30秒までは急激に増大し, その後, 作業終了までゆるやかな血流量の増す傾向がみられた。
4.最大筋力の20, 30%の負荷で得られた作業中の血流量は, 作業終了まで急激に増大してゆく傾向がみられた。
5.最大筋力の5, 10%の負荷で得られた作業終了直前の血流量は, 作業終了直後の血流量に比べてほぼ同じか, 作業終了直後血流量が作業中血流量を上廻ることがなかった。
6.最大筋力の20, 30%の負荷で得られた作業終了直後の血流量は, 作業終了直前に得られた血流量に比べて高い値を示した。
7.以上の結果から, 最大筋力の10%までの負荷を用いた前腕の律動的作業では, 作業中に筋作業の代謝に必要な血液量が供給され, 疲労することなく作業が長く続けられると考えた。抄録全体を表示PDF形式でダウンロード (1182K) -
