In the studies of physical motion analysis the multiple photographic method with a stroboscope or the fast motion picture which has been used, are not sufficient to pursue a motion of some kinds of sports and of some hidden physical spot only from one direction and difficult to synchronize picture obtaind from three direction.
To make use of electrical engineering from the points of Physiology and Kinesiology, it is worthy of pursuing a physical motion on three dimensions, up & down, right & left and before & behind at once, and furthermore, physiological phenomena in electrocardiogram and electromyogram with connection to the above analyzer.
For that purpose a physical locomotion pursuit analyzer (SN-type, refered to PLPA later on) was devised.
The present devised analyzer is composed of a three dimensions-accelerometor in a gyroscope, a preamplifier, a integration amplifier and a pen-writing recorder.
As already known in the principle of physics, velocity can be obtained by single integration of acceleration rate and displacement by double integration of a acceleration rate.
In above the PLPA, therefore, acceleration rate, velocity and displacement, each of three dimensions can be determined. Capacity of the present analyzer was as follows; Frequency rate : 1.5-20.0 HZ (Static accelerated component under 1.5 HZ was cut by differentiation circuit of DC-cut), time constant of electrical integration circuit : about 0.2sec.
In the present report the outline of PLPA and some data of our experiments obtained by use of it were dealt.
The problems of the telemetering system of this analyzer and digital exhibition by connection to computer require further study.

In the present studies it was examined to begin with, whether intentional fixed quantity of exercise in response to previously defined level of heart rate could be loaded by treadmill connected with“Heart Rate Controller” (Quinton Co., Ltd.) i.e. a series of patterns in running exercise of the normal adult males were analysed.
The obtained results in short are in the following ;
1) Running exercise in response to previously defined level of heart rate being carried out by use of the above“Heart Rate Controler”, speed of treadmill needed to be adjusted manually until heart rate reached the defined level and then controlled automatically.
2) The relations between treadmill speed and heart rate defined at 130 Beats/min, 150 or 170 each, are as follows.
a) Treadmill speed at heart rate, previously defined as 130 B/min was 80±5-12 meters/min, actual heart rate during above exercise was 130±3-8 B/min in record.
b) Treadmill speed at heart rate, 150 B/min was 100±9-18 m/min, actual heart rate 150±6-8 B/min in record.
c) Treadmill speed at heart rate, 170 B/min was 130±10-33 m/min, actual heart rate 170±3-9 B/min in record.
As previously defined heart rate level was indreased, actual level in record deviated from the former within some extent and treadmill speed was also raised to maintain the defined heart rate level.
Fluctuation width of treadmill speed varied remarkably by the individuals.
Adjustment of treadmill speed was considered to be well under control by feedback mechanism of“Heart Rate Controller”.

It is significant for whole body training of endurance ability or exerise as rehabilitation treatment of various diseases, that a fixed quantity of exercise in response to a defined level of heart rate could be loaded voluntarily.
In the present studies it was determined heart rate, respiration rate, number of steps, treadmill speed, moreover, relationship between treadmill speed and heart rate, sudden change of exercise strength on intentional fixed quantity exercise in response to previously defined level of heart rate could be loaded by treadmill connected with “Heart Rate Controller (Quinton Co., Ltd.) ”.
A series of patterns in treadmill running of the normal adult males were analyzed.
On the other hand, transition of blood chemical substances during above exercise at defined heart rate were determined by use of the SMAC-System autoanalyzed (Technicon Co., Ltd.) .
The obtained results in the follows;
1) The relation between treadmill speed and heart rate defined at 130 beats/min, 150 or 170 each, are as follows.
a) Treadmill speed at heart rate, previously defined as 130 b/min was 80±5-12 meters/min, actual heart rate during above exercise was 130±3-8 b/min in record.
b) Treadmill speed at heart rate, 150 b/min was 100 ±9-18 m/min, actual heart rate 150±6-8 b/min in record.
c) Treadmill speed at heart rate, 170 b/min was 130±10-33 m/min, actual heart rate 170±3-9 b/min in record.
2) In the present studies respiratory rate during exercise at defined heart rate level neither altered nor had relation with treadmill speed. The number of steps did not alter, rather appeared to determine respiratory rate.
3) When sudden change of exercise strength during exercise at defined heart rate level appeared, for instances, treadmill speed got quicker, deviated raise of rate from defined heart rate level varied by the individuals and also load on heart itself did by the individuals.
4) In determination of blood chemical substances during exercise at defined 150 b/min or 170 b/min of heart rate level by SMAC-System, transition of above substances were observed to be within normal range but thier levels before exercise were promptly restored.
From the results mentioned above it is suggested that process of intermediated metabolism during above exercise could be considerably stable and exercise load at a defined heart rate level can be prescribed intentionally.
