The pulse rate per minute was between
120 and 150, which is ideal.
(It was lower during Patterns than during
fast Singing Calls.)
Here some remarks which I should like to add:
Square Dancing is as beneficial to health as swimming and cycling! Tests made at the "Sporthochschule" in Cologne showed that most joggers do more than is good for them. They recommend those exercises which aim at flexibility and coordination of movement, best achieved by "swimming, gymnastics or square dancing". Prof. Dr. Hollmann from the "Sporthochschule" (physical education college) in Cologne states, that these are the kinds of sport most beneficial to heart and circulation.
Persons under the age of 50 should reach a pulse rate per minute of no less than 130 and no more than 160; if over 50 not more than 180 minus age, but a short time 150 will do no harm. Training of this kind has many positive effects: The heart beats more slowly, but pumps enough blood, and with it oxygen, into circulation, which means it works more economically. It also favours the condition of the blood, and so reduces the danger of thrombosis. It stimulates the forming of HDL-cholesterol vital for the prevention of arteriosclerosis. And lastly it stimulates the whole metabolism and wellbeing.
Therefore: Square Dance is not only "in", but also a wholesome and gay sport which is flexible enough, so that nobody needs to feel overstrained.
So lets Square Up.
