JOURNAL FREE ACCESSThe treadmill Exercise was performed for 26 asthmatic children (EIA+) with mask, under the circumstance of Temp 26°C, Humidity 95%. We have also examined these children with a special jacket (60 mmHg pressure) doing the treadmill.
1) The comparison of FEV 1.0 and PEFR with room air and moist air showed similar pattern post 5 min exercise. However, the fall of FEV 1.0 differed drastically, resulting in 44% fall for room air, and 27% for moist air. (P<0.01)
2) The children who wore the jackets differed drastically from the room air children post exercise. (P<0.05)
3) From these results, we predict that such exercise as swimming suits the condition with adequate moisture, pressure, and its method of breathing which prevents Exercised Induced Asthma attack.View full abstractDownload PDF (1934K) -

JOURNAL FREE ACCESSAn electromyographic silent period appears prior to initiation of a reaction movement. In order to estimate the mechanism of the silence, the statistical properties of the EMG before the onset of the phasic discharge were investigated. The EMG activity was processed as a stochastic process, and the statistical properties were analyzed. It was found that the mean of the rectified EMG decreased from 100 ms before the onset of the phasic discharge. As to the relationship between the silence and the depression of the EMG activity, it was estimated that the depressing influence was so remarkable that the silent period was observed.View full abstractDownload PDF (815K) -
—BISECTION OF A RANGE OF MOTION—JUNKO MIYAZAKI, HIROSHI KURATA, YOSHINORI OGAWA, YOSHIHIRO SAITO, ATSU ...1982 Volume 31 Issue 4 Pages 242-250

JOURNAL FREE ACCESSIn order to examine the personal space perception, measurements were conducted on both elbows in 14 men and 46 women. Each subject, with his (or her) eyes closed and with his upper arm fixed horizontally, was instructed to stop the vertical and horizontal swing motion of his lower arm at the point he considered to be the middle of the range of possible motion on the front and side of plane at his shoulder, and this was repeated ten times. In various conditions, similar measurements were also done to study factors affecting the personal space perception in 14 men.
Mean values of bisected angles in percentage against range of motion were deviated from the middle points in the direction of the elbow extension, although there were large differences between the individuals. The deviation was smallest in the vertical. side of plane, and was larger in the horizontal plane than that in the vertical plane. The deviation was not so much affected by the various conditions.
It was suggested that the gain of the personal space perception is higher in the elbow extension than in the elbow flexion and its difference is larger in the horizontal plane than in vertical plane of the human elbow joint.View full abstractDownload PDF (885K) -

JOURNAL FREE ACCESSMale rats of 80 weeks of age were divided into 2 groups, sedentary group (Group I, n-7) and exercise-trained group (Group II, n=8) . Rats in Group II were conditioned by a 4-weeks treadmill running program. These two groups and another group of male sedentary rats of 20 weeks of age (Group III, n-9) were all subjected to a Wiggers type hemorrhagic shock (mean arterial pressure of 30 torr. for 60 min.) . Pulse rate and pulse pressure during the shock experiment, acid-base balance indices and blood gas before and after the shock period, and survival rate within 7 days after the shock experiment were compared between the three groups.
Animals in Group I showed remarkably decreased pulse pressure during the shock period. Metabolic acidosis after the shock period in Group I was remarkable, resulting in a significantly higher mortality compared with Group III. In Group II, pulse pressure during the shock period was higher than in Group I. Metabolic acidosis after the shock period in Group II was less marked than in Group I, and mortality tended to be lowered in Group II.
These results indicated that physical training induced resistance to hemorrhagic shock in aged rats. One of the mediating mechanisms in this cross-adaptation between exercise and hemorrhagic shock may be changes in oxygen transport system.View full abstractDownload PDF (796K) -

JOURNAL FREE ACCESSHeat balance during 1hr exercise at 450 kpm/min was measured on 5 healthy male students wearing only shorts in a climatic chamber of 13°C and r.h. 60% at the minimum phase (5 : 00-7 : 00), the rising phase (11 : 00-13 : 00), the maximum phase (17 : 00-19 : 00) and the falling phase (23 : 00-1 : 00) of body temperature.
Heat production was nearly constant, 194 to 209w/m2 at all phase both in summer and winter. Evaporative heat loss was lowest at the minimum phase and highest at the maximum phase. In all phases, evaporative heat loss was 14-29% higher in summer than in winter. Dry heat loss was not significantly different summer and winter. Body heat storage was high at the minimum phase, low at the maximum phase and higher in winter than in summer. The threshold rectal temperature for the onset of sweating was lower at the maximum phase than at the minimum phase by 0.65°C in winter and by 0.70°C in summer.View full abstractDownload PDF (867K) -
