Effect of whole body vibration versus resistive exercise on premenstrual symptoms in adolescents with premenstrual syndrome

Abstract

Abstract Background Premenstrual syndrome (PMS) is a cyclic disorder that affects social activities, interpersonal relationship, and educational productivity of adolescents. Therefore, this study aimed to compare the effect of whole body vibration (WBV) and resistive exercise on premenstrual symptoms in adolescents with PMS. Methods Sixty adolescents, aged 16–19 years and with body mass index > 19.9 kg/m2, participated in the study. They were randomly assigned to three groups equal in number. Control group received magnesium (Mg) (250 g) and vitamin B6 supplementation once daily. Resistive exercise group received the same supplementations and resistive exercise for three times/week, while the WBV group received the same supplementations and WBV training three times/week for 12 weeks. Premenstrual syndrome questionnaire (PMSQ) was used to evaluate premenstrual symptoms, including anxiety symptoms (PMS-A), depression symptoms (PMS-D), craving symptoms (PMS-C), hyperhydration symptoms (PMS-H), other symptoms, cramp, and low back pain. Results Pair-wise comparison test revealed a significant decrease (p = 0.000) in PMS-A, PMS-C, PMS-D, PMS-H, other symptoms, cramp, and low back pain of the resistive exercise group and WBV group after treatment. However, there was only a significant decrease in PMS-C (p = 0.03) of the control group after treatment. Post hoc test showed no significant difference (p > 0.05) between the resistive group and WBV group in all PMS symptoms after treatment. Conclusions Passive muscular training using WBV has a similar effect to resistive exercise on premenstrual symptoms that affect the quality of life in adolescents with PMS.
