JOURNAL FREE ACCESSBefore and after the physical fitness tests included 1000 meter endurable walking, aged males and females more than 61 to 80 years old were tested on the blood pressure, heart rate and blood components. The results were as follows.
1) The systolic and diastolic blood pressure were not varied so distinctly.
2) Heart rates were increased in all groups.
3) Serum cholesterol, GOT and GPT were not influenced.
4) Fatty acid, especially unsaturated one, was increased remarkably.
5) Fatty acid increasing observed on excellent performer of the endurable walking was higher than that of poor performer.
6) Increasing ratio of the fatty acid which was found on the subjects with abnormal ECG was higher than that of the subjects with normal ECG.
As above mentioned facts, the test of serum fatty acid seemed very important item to the aged people from the view point of security of the exercise.View full abstractDownload PDF (1014K) -

JOURNAL FREE ACCESSThermoregulatory responses during one hour pedalling on bicycle ergometer were measured in a climatic chamber of 26°C at various humidity levels. Work intensities were 30, 40, 50, 60 and 70% of Vo2max. Relative humidities were 30, 60 and 90%.
1) Oxygen intake remained nearly constant at the same work load and was not influenced by humidity level.
2) At work intensities of more than 60% of Vo2max the elevation of rectal temperature was augmented by increased humidity.
3) The secretion of sweat increased, but the evaporation of sweat decreased with increased humidity, particularly at work intensities of 60% and 70% of Vo2max.View full abstractDownload PDF (1003K) -
(2) VARIABILITIES OF H-WAVE AMPLITUDE AT PRE-AND POST-PHONATIONYOSHIBUMI NAKAHARA, TATSUYA KASAI1978 Volume 27 Issue 1 Pages 19-24

JOURNAL FREE ACCESSIn this study, it was attempted to clarify the neurophysiological mechanism of voluntary movement (phonation) recording evoked EMG (H-wave) which have been studied by Magladery and others basing on the Hoffman's study about monosynaptic reflex. The indicator was the amplitudes of H-wave which were evoked on M. soleus by stimulation on the afferent nerve fibers contained in N. tibialis. Variations of H-wave amplitudes were plotted in relation to the time elapsed from initiation of phonation and were investigated about the central nervous system in relation to it.
As the results of this study, following conclusions were led;
1) At the stage of pre-phonation period, average values of H-wave amplitude were higher than those of control. This result was understood as impulses which were commanded to contract the muscles for phonation raised alpha motoneurones in reflex arc of lower limbs, simultaneusly.
2) The damping phenomenon of H-wave amplitudes were observed just prior to pre-phonation. But the neurophysiological mechanism of it is unknown in detail, now.
3) The H-wave amplitudes showed the highest value in agreement with initiation of phonation. This phenomenon was called as Jendrassik's Maneuver. This effect was understood that Jendrassik's Maneuver had some functional connection to the reticular formation of brain stem.
4) After the initiation of phonation, the inhibitory phenomenon of H-wave amplitudes (this level was lower than that of control) was observed at most of subjects. The neurological mechanism of this phenomenon is unknown.View full abstractDownload PDF (694K) -

JOURNAL FREE ACCESSHeart rate and R-R intervals of ECG during sleep were examined in healthy young men. Heart rate per minute were gradually decreased when the subject fell asleep. Whole through one night sleep data there were two typical heart rate variation patterns, namely stable stage and fluctuating stage. Sleep stages determined by EEG, EOG and EMG of chin corresponded with these two patterns; slow wave stage (Stage III/IV) showed the stable pattern, REM Stage and Stage I showed the fluctuating pattern, Stage II both patterns. The fluctuating pattern showed higher heart rate level.
Further studies computed R-R intervals and its variations of ECG revealed 4 typical patterns on the variations, and well corresponded with sleep patterns determined by the above methods. R-R interval varied from 1.39 to 0.67 sec during sleep. R-R interval variation befor onset of sleep showed lightly rythmical periodicity (20-40 sec) and small fluctuation (0.1 sec) (awaking pattern) . R-R intervals after onset of sleep extended gradually, fluctuating midly (0.1 sec) and did not show any periodicity (transient pattern) . R-R interval reached its maximum level then. At slow wave stage (S-III/IV) R-R interval showed mild fluctuation as the transient strage, and did not show any periodicity (stable pattern) . At REM stage and S-I it showed large fluctuation (more than 0.2 sec) and significant periodicity (10-30 sec) . At S-2 if the stage was in the course of deepening the sleep, it showed stable pattern and if it was in the course of lightening the sleep it showed fluctuating pattern.View full abstractDownload PDF (664K) -

JOURNAL FREE ACCESSThe variation of venous concentration of FFA as the effect of exercise under several nutritive conditions were tested on two subjects, i, e., 56 years old male and 20 years old female.
Arrhythmia were recorded when sudden increase in palmitoleic acid in venous concentration was observed, while no arrhythmia were recorded otherwise. Arrtythmia seemed to have been prevented by intaking glucose prior to exercise.
It was also observed that arrhythmia would easily be produced by sudden uprise of palmitoleic acid under hunger after low carbohydrate nutrition.View full abstractDownload PDF (598K) -
