| Summary: | Background: An important feature determining physical capacity of a human being is muscle strength. In preventive healthcare, vibration training can offer a safe and attractive way to strengthen muscles in people of all ages. The aim of the study was to determine the influence of stochastic resonance whole-body vibration (SR-WBV) training on the maximum moment of muscle strength in the knee and elbow flexors and extensors among healthy young women.Methods: The study participants comprised 112 women aged 19-25 years (65 SR-WBV, 47 Control). The following were the SR-WBV training parameters: 12 sessions of stochastic vibration were performed on a two-plate platform in standing position, twice weekly for six weeks with nine series of vibrations in each session lasting 55 seconds, at an amplitude range 0.5-3.5 mm and frequency of 2-8 Hz. Measurement of the moment of muscle strength was static and lasted 30 seconds.Results: In the SR-WBV group, the median of the mean value for the maximum moment of muscle strength before and after training was, respectively: 36.0 vs. 44.0 Nm (p=0.003) right knee flexors; 36.0 vs. 41.0 Nm (p=0.024) left knee flexors; 67.0 vs. 83.0 Nm (p=0.059) right knee extensors; 66.0 vs. 82.0 Nm (p=0.021) left knee extensors; and 19.0 vs. 21.0 Nm (p=0.014) right elbow flexors; 18.0 vs. 20.0 Nm (p=0.002) left elbow flexors. In the control group, there were no significant differences between the results obtained before and after six weeks.Conclusions: In young women, SR-WBV training performed in standing position increases the moment of strength of the knee flexors and extensors, as well as the moment of strength of the elbow flexors. However, it does not affect the elbows extensors. In young women, SR-WBV training is beneficial for muscle strength and could be widely used to improve muscle strength. |
