Cumulative Effect of Asanas Influence Upon One’s Organism

Asanas exert an intense effect upon one’s cardiovascular system. Having investigated the mechanisms of asanas impact we have established the existence of a cumulative effect emerging in terms of performing a set of asanas.

In other words, the effect of asana performing shall be enhanced if asana is performed repeatedly, several times in a row.

Let us look at the cumulative effect on the instance of Bhujangasana performance.

The objective of the experiment was:

- to define changes occurring in the most simple hemodynamics parameters (systolic blood pressure, diastolic blood pressure and heart rate) when performing Bhujangasana;

- to compare them with similar changes occurring in terms of performing Bhujangasana consequently, 3 times in a row (the asanas were performed with short rest periods of 3-4 minutes done between asanas for stabilization of system hemodynamics’ parameters).

The research was performed with help of tonometer produced by AnD company, model UA-668.

The determinations were done prior to asanas performance, underway (on the 1st, 2nd and 3rd minutes) and after coming out of asanas (immediately, on the 1st, 2nd and 3rd minutes – up to parameters stabilization).

The experiment was performed on 2 research subjects coming from the same age group (female, 57 years old). In this case the 1st subject is the normotensive person and the 2nd one is the hypertensive one (the anamnesis shows hypertensive disease II d).

- Systolic («upper») blood pressure (SBP);

- Diastolic («lower») blood pressure (DBP);

- Heart rate (HR) (pulse).

* the data drawn in tables has been reduced (if compared to those studied in scope of the experiment) for the sake of convenience of the observed phenomenon’ illustration.

Upon analysis of the received data we can see that the performance of Bhujangasana leads to decrement of SBP parameter both in the 1st and in the 2nd cases.

We can also see that the three-time performance of Bhujangasana reduces the parameters to some lower figures. Thus we can speak about the cumulative effect of asana’s impact upon one’s organism. The similar effect from energetic point of view has been described in the book of A. G. Safronov «Yoga: Physiology, Psychosomatics, Bioenergetics», Kh., 2008; in order to achieve it one should apply the principle of asanas effect’ enhancement upon the organism (p. 138).

In the case of the research subject No. 1 we can see the rise of DBP figures that may indicate a tendency to hypertension that has not been yet identified (the system regulating the vascular tone may fail to cope with the load imposed).

Another interesting fact is that while the DBP is coming up the heart rate goes down – here we can speak about compensated pathology since the heart and blood vessels «support» each other’s work.

In case of the 2nd experiment participant who has the hypertensive disease in her anamnesis we may speak about therapeutic effect of asana — the parameters have steadily declined. The DBP figures showing the state of vascular tone have normalized (DBP = 70 mm Hg). The big difference between the input parameters and the parameters measured after asana performance for three times may indicate that the system of CVS performance regulation is far from perfection against the disease present.

This is an interesting effect that requires further study — at least, it is interesting to find out more precise coefficients of correlation between the number of performed asanas and the figures of system hemodynamics parameters change.
