What are vibrations and what is their role? How do they affect body composition and weight loss? The aim of this paper is to provide a summary of previous research related to the effects of vibration training on body composition and weight loss. Vibration is a mechanical oscillation that can be defined by frequency and amplitude and its frequency is defined as cycles per unit time and is generally measured in units of hertz (Hz) cycles per second. There are three types of vibration used today for training purposes: vertical, oscillating, and 3D vibration. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analyzes) guidelines for reporting in systematic reviews and meta-analyzes were used to summarize previous research on how vibrations affect body composition and weight loss and the search was performed in the Web of Science and Scopus databases (until September 10, 2020) for papers that are in English and peer-reviewed. Papers are included in the systematic review if they met the criteria of the so-called PICO (Patient / Population, Intervention, Comparison, Outcome) form, which includes the population or groups to be studied, population intervention, comparative intervention or control, and the outcome of the intervention. From the default search strategy, 277 possible papers initially were emerged and only 12 of them met the conditions for inclusion in the discussion. Based on the processed works, it was found that vibration treatment has no significant effect on weight loss, while the same significantly affects the change in body composition, mostly in the form of reduced body fat or increase in lean body mass. It is also evident that the application of different frequencies gives the same results as well as that the vibration treatment has a positive effect on the composition of the body regardless of the age group to which it is applied.
