Abstract
This study was conducted to determine the effect of resistive exercise versus whole body vibration on premenstrual syndrome (PMS). Thirty young females aged 16-20 years were randomly distributed into two groups: resistive group received medical treatment in the form ofvitamin.B6 once daily for 12 weeks and engaged in a program of resistive exercise, 3 times/week for 12 weeks and whole body vibration (WBV) group received the same medical treatment and engaged in a program of WBV training, 3 times/week for 12 weeks. Premenstrual symptoms were assessed by using premenstrual syndrome questionnaire (PMSQ), and blood sample were taken to measure levels of estradiol (E2), progesterone and prolactin before starting and after the end of the treatment program. Results revealed that the resistive group showed a highly significant decrease in premenstrual symptoms score (p=0.0001), progesterone (p=0.0001), prolactin (p=0.0001) and significant decrease in estradiol (p=0.004) post treatment. While WBV group showed a highly significant decrease in premenstrual symptoms score (p=0.0001), prolactin (p=0.001)and a significant decrease in estradiol (p=.042), progesterone (p=0.039) post-treatment. However, resistive group showed a highly significant decrease in premenstrual symptoms score (p=0.0019) and a significant decrease in estradiol (p=0.0027), progesterone (p=0.046) and prolactin (p=0.042) when compared to WBV group. It can be concluded that both resistive training and WBV have a positive effect on PMS through improving related symptoms of PMS and reducing levels of estradiol, progesterone and prolactin that are involved in PMS symptoms. However, the resistive exercise is more effective than WBV in treating PMS in young females
