Effect of 1 week '61-points relaxation training' on cold pressor test induced stress in premenstrual syndrome

The present study was conducted on 50 clinically healthy women volunteers who were in their reproductive age group and in their premenstrual period. Thirty women having premenstrual syndrome (PMS) were compared with 20 control women to evaluate 1 week training of 61-points relaxation (61-PR) yogic exercise. In both the groups cold pressor test (CPT) was performed; and systolic blood pressure (SBP; mmHg), diastolic blood pressure (DBP; mmHg) and heart rate (HR/min) were measured. Basal SBP, DBP and HR of women with PMS was significantly higher than the control subjects with P value 1.2E-05, 0.000583 and 0.005707 respectively, suggesting the presence of stress in women with PMS. Immediately after CPT, the said parameters were statistically significantly more raised in PMS group than control group (P = 6.14E-05, 2.78E-06, 0.003799) respectively. Following 1 week of 61-PR training, the control group showed a significant decline in SBP, DBP & HR (P = 0.00769384, 0.00852894, 0.62316217) respectively. However, the PMS group showed a statistically highly significant reduction in SBP, DBP & HR (P = 2.55E-07, 4.35E-07 and 6.4904E-06) respectively immediately after CPT. These results suggest a reduction in sympathetic activity by 61-PR training and it can be used as an effective relaxation tool during premenstrual stress.
