About this study

Methods: A prospective, randomised, pre-post-test, single-blind, controlled study was conducted in 34 women diagnosed with PMS. Participants were randomly assigned into three groups: the Aerobic Exercise Group (AEG, n=11), the Whole-Body Vibration Training Group (WBVT, n=11), and the Control Group (CG, n=12). Participants in the AEG performed 45-minute exercise sessions (10 minutes warm-up, 30 minutes walk, 5 minutes cool down) three times a week for eight weeks. The WBV program was conducted using a 25 Hz frequency and a 2 mm low amplitude on the Power Plate® (pro5TM) machine, which provides three-plane oscillatory motion. The program lasted eight weeks, with sessions held three days a week, ensuring at least one rest day between sessions. The control group was asked to continue their daily life routines. Dietary intake of all participants was monitored, and those with different diets were excluded from the study. Premenstrual Syndrome Questionnaire (PMSS) was used to evaluate PMS symptoms and Visual Analogue Scale (VAS) was used to evaluate pain.

Treatment and study plan

Aerobic Exercise Programme

Other

The aerobic exercise programme was shown to female students with premenstrual syndrome on the first day by the researcher (D.A.) at the sports centre. Participants were advised to drink water and wear running shoes during exercise. Warm-up exercises were performed for 10 minutes before the exercise. Exercise intensity was determined by the Karvonen formula (HRmax=220-age, HRR=HRmax-HR rest, 60% THR=(0.60xHRR)+HR rest). .According to the pulse rate of the exercise, pulse values are monitored on the treadmill and km/hour speeds are adjusted according to pulse values. The exercise programme started with low aerobic exercise intensity on the treadmill, gradually increased at 5-minute intervals and completed at 40-60% of the heart rate, and finally 5 minutes of light stretching movements were performed to return to the initial state. In the following sessions, the participants performed the exercise programmes individually at the sports centre for 45 minutes (10 min warm-up, 30 min walk,

Whole Body Vibration Training Programme

Other

The WBV programme used a frequency of 25 Hz and an amplitude of 2 mm (low amplitude). The Power Plate® (pro5TM) machine provided the device's vibration. This device provides a three-plane oscillatory motion. The programme lasted eight weeks and was performed three days a week. There was at least one day's rest between each session. Before and after each vibration, stretching exercises (warm-up and cool-down programme) were performed for 5 minutes, particularly for the quadriceps and trunk extensors

Primary outcomes

  1. Premenstrual Syndrome Scale (PMSS)

    Time frame: baseline-8 week

    The scale, which was developed and a validity and reliability study was carried out by Gençdoğan to measure premenstrual symptoms and determine their severity, consists of 44 items in 5-point Likert type. PMSS total score' is obtained by summing the scores obtained from these sub-dimensions. The lowest score that can be obtained from the scale is 44 and the highest score is 220. A high score indicates that the intensity of PMS symptoms is high. When the results of the PMSS are evaluated, it is decided whether PMS is present or absent according to whether the total and subscale scores exceed 50% of the highest score that can be obtained

  2. Visual Analogue Scale (VAS)

    Time frame: baseline-8 week

    In all groups, the pain intensity of the patients will be graded between 0 (no pain) and 10 (unbearable pain) using VAS. VAS is a very common scale used for pain assessment in daily practice and pain averages ranging from 0 to 10 are given in this assessment. Accordingly, '0' indicates the absence of pain, while a mean VAS value of 1-4 indicates mild pain, 5-6 indicates moderate pain and 7-10 indicates severe pain
