Right : The object of this study was to investigate in details how the pulse rate of the farm animal changed according to various intensity of work.
As the experimental animals two castrated goats were used. They were 2 years old and weighed about 26 kg.
The work imposed on the goat was the walking on the horizontal treadmill which turned at the rate of 42.9meters a minute. The draft resistances for the goats in walking were four kinds, 2 kg., 3 kg., 4 kg. and 5 kg.: the walking hours were three kinds, 10 min., 20 min. and 30 min. Accordingly, the work imposed on the experimental animals had twelve varieties.
The pulse rates were examined just before, during and soon after the work and during the recovering period, by means of the stethoscope.
During the work, the treadmill was stopped at 2 minutes intervals and the pulse rate examined as soon as the mill stopped on each occasion. The treadmill was also stopped for a little while, at most 15 seconds, during the work in order to count the pulse rate. Principal results obtained were as follows:
1. The pulse rate was increased rapidly on accoun t of the work, especially during the first 2 minutes after the beginning. We called this rise in the pulse rate the early rising. During the work the early rising was followed by a gradual increase of the pulserate, the extent of increase depending on intensity of work. This gradual increase was called the late rising by us.
When the work was over, the pulse rate decreased rapidly, especially in the first 2 minutes after work. We called this fall in the pulse rate the early falling.
After the work the early falling was followed by the gradual decrease, and then the pulse rate recovered to such a level as before the work in due time. We called this gradual decrease of the pulse rate the late falling.
2. The increasing rate of the early rising was nearly proportionate to the increase of draft resistance against the pull of the goat, and an individual difference was shown between the two goats. The change in this increasing rate was especially remarkable when the draft resistance had been changed from 3 kg. to 4kg. Then, so far as the draft resistance was concerned, it seemed that such resistance was the limit between the moderate and the too heavy load for those goats.
3. The curve of the late rising of the pulse rate in the 30-minute work became nearly horizontal or a little upward going when the resistance had been 3 kg. or 4kg., and was considerably steep when it had been 4kg. or 5 kg. From this fact we can presume that when the draft resistance is more than 4kg. it is overloading for the adult goat.
4. The decreasing rate of the early falling was also nearly proportionate to the increase of draft resistance against the goat, regardless of the duration of walking, and an individual difference was also shown between the two goats. Changes in the decreasing rate were especially remarkable when the resistance had been changed from 3kg. to 4kg. This tendency in the early falling was almost the same with that observed in the early rising of the pulse rate, though the rate of the former was a little greater than that of the latter.
5. Regardless of the duration of walking, the curve of the late falling declined gradually when the resistance had been 2 kg. or 3 kg., and more steeply down when it had been over 4 kg. This tendency in the late falling resembled that in the above-mentioned late rising.
6. For every piece of work imposed in this experiment, we measured an area demarcated by the curves of the early and late rising, and the early and late falling of the pulse rate and their base lines on the graph. The planimeter method was used for this measurement. We called this area temporarily the area of pulse-rate curve.
