Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study was attended by female students of the University of Physical Education in Krakow aged 19 to 25. There were 3 study groups: interventional and 2 active control groups. Allocation of subjects into different groups was done through volunteer sampling - the participants were recruited via posted advertisement at the university and assigned to the group to which they volunteered. Women from the interventional group took part in 36 individual training sessions on the vibrating platform (3 times a week for 3 months). Wole body vibration (WBV) training was carried out using the Fitvibe Excel Pro vibrating platform (Germany), which generates vertical vibrations with a frequency in the range of 20-60 Hz and an amplitude of 2 and 4 mm. The training protocol included warm-up, the main part consisting of static and dynamic exercises, and calming exercises at the end of the workout. Warm up included 6 modified jumping jacks, 3 hip circles in both directions, 6 lunges (3 for each leg). Static exercises included holding a standing position, holding a squat position, holding a strap in a standing position with shoulders raised. Dynamic exercises included deep squats, split squats for each leg. Calming exercises comprised of upward facing dog yoga pose and rolling like a ball. The duration of a single exercise on vibration platform was 1 minute. Between each exercise there was a 1-minute break during which women walked around the room. During dynamic squats the pace was 25 movements per minute (metronome was used). The vibration amplitude (2 mm) as well as the duration of exercises and breaks between them did not change throughout the whole duration of the training cycle. During the first 12 training sessions, the vibration frequency was 40 Hz, then increased by 5 Hz after 12 consecutive sessions (40-45-50 Hz). All trainings were supervised by a physiotherapist or a trained person and were conducted individually. To assess adherence to the intervention a session attendance checklist was used. The intervention took place at University of Physical Education in Krakow in a specially prepared room where the vibrating platform was located. This room had the same temperature and humidity during the whole training cycle.

Treatment: Devices
Comparator / control treatment
There were 2 active control groups. One group followed the same training protocol as the interventional group but without vibrating platform. The other control group performed no exercises at all and didn't attend any sessions, apart from 2 appointments (at the beginning and the end of the research period) for evaluation of studied indicators.

Summary
Brief summary
The purpose of the study is to compare the impact of single and repeated whole body vibration training on changes in hemorheological parameters, indicators of oxidative stress and endothelial functions markers in healthy, young and non-training women. Another goal of the study is to asses changes in lower limb explosive performance capacity, bone turnover markers and cognitive functions after 12-week whole body vibration training. Volunteer sampling was used to select 46 women split into three groups. Women from the interventional group took part in 36 individual training sessions on the vibrating platform (Fitvibe Excel Pro). There were 2 control groups: no treatment and active control. There was no intervention in no treatment group, while in the active control group exercise training was performed but not on the vibration platform. The training protocol in interventional group and in active control group was the same and included warm-up, the main part consisting of static and dynamic exercises, and calming exercises at the end of the workout. All trainings were supervised by a physiotherapist or a trained person and were conducted individually. The hypotheses assume favourable changes in the above-mentioned parameters.
