| The work presents the research and analysis concerning general low frequency vibration and its effect on energy balance of a human organism (a comparison with a control group). The research was conducted in two phases: a group exposed to vibration and a control group. An exposed group (28 participants) took part in 19 training sessions, each lasting 20 min, of low frequency vibration (around 3.2 Hz in standing position) applied to each participant at fixed time of the day. Before and after the session, the thermographic images were taken and deep temperature was taken too. The control group (33 participants) also took part in 19 everyday 20-min sessions with no vibrations and only measurements conducted. The results were analysed concerning statistics using Statistica. For the sake of the analysis the significance level was p = 0.05, the parametric T - test, and the non-parametric Kołmogorow-Smirnow tests were used for two groups of independent variables. Having conducted the research and analysis, one can state that 20-min exposure to low frequency vibration results in significant positive changes in chosen parameters. |
