RESULTS

Part one of the study

In a comparison with the normal sighted, subjects with impaired vision had significantly higher breath rates, diastolic blood pressure values, and heart rates. For breath rate. Z µ 2.71 and Z.01 (2) a = 2.57, hence P< .01; for diastolic blood pressure: W = 3.79 and Z.001 (2) µ = 3.20, hence P<. 001, and for heart rates: Z µ = 1.66 and Z.05 (1) et = 1.64, hence P<.05. The group mean values ± SD are presented in Table 1.

Part two of the study

There was a significant decrease in the breath rate of the yoga group, at the end of three weeks using the Wilcoxon paired signed ranks test (T=10, T.05(2) 12 = 13, hence P<.05). The group mean values ± SD are presented in Table II.
