RESULTS & DISCUSSION


The group mean values and Standard Error of the Mean (SEM) for oxygen consumption, breath rate, and breath volume are given in Table I.

Two factor ANOVA
There was a significant difference between values recorded before and after the sessions of CM and of SH (i.e., Factor B) for: (i) oxygen consumption (F = 8.38, for DF = 1,156, p<.001), (ii) breath rate (F = 12.70, DF as above, p<.001), and (iii) breath volume (F = 15.82, DF as above, p<.001). There was no significant change in minute ventilation (P>.05). The difference between assessments made after and before the sessions was not significant (Factor A), with no significant interaction between Factors (A X B).

(F = 15.82, DF as ab ove, p<.001). There was no significant change in minute ventilation (p>.05). the difference between values of the two types of sessions (i.e., CM, SH) were not significantly different (Factor A), with no significant interaction between Factors (A x B).
 

Tukey multiple comparison test
The average respiratory rate recorded after cyclic meditation was significantly lower than the average value recorded before (q = 4.65, p<.01). The respiratory amplitude, in contrast was significantly higher after cyclic meditation compared to before (q = 4.95, p<.005).

Paired t test
The oxygen consumption decreased significantly after cyclic meditation (32.1%, p<.001) and  shavasan (10.1%, p<.05). Also, the breath rate was significantly lower after both sessions: after cyclic meditation a decrease of 3.6 cycles per minute (p<.001), and after shavasan a reduction of 1.9 cycles per minute (p<.001). In contrast, the breath amplitude, which is related to the depth of breathing, was significantly higher after both types of sessions: after cyclic meditation an increase of 28.8% (p<.001) and after shavasan an increase of 15.9% (p<.001). Minute ventilation decreased by 10.44% after SH(p<.05).

Pearson correlation coefficient
There was no significant correlation between percentage change after both CM and SH sessions, in (1) oxygen consumptions, (2) respiratory rate, and (3) breath volume. with (1) experience in youga
