Introduction: All adaptive processes within and on the body triggered by training occur during recovery. The available literature and the number of studies on recovery following sports training significantly lag behind the knowledge concerning the active part of the training process. The central and autonomic nervous systems, under the influence of physical activity, are susceptible to fatigue, which significantly alters their functional characteristics. For this reason, it is necessary to study, develop, and apply recovery methods after physical activity to shorten the adaptation period, thereby making the training process more efficient and safer. The use of sound and sound vibrations for healing and achieving general well-being dates back to ancient times and is still intensively used in unchanged forms among some indigenous peoples today. Scientific research conducted, prompted by the effectiveness of this phenomenon, increasingly confirms its efficacy. Therefore, it is not only necessary but also imperative to explore the potential application of such practices in kinesiology. Research Objective and Hypotheses: The presented research aims to investigate the effects of sound-vibration therapy on the activity of the autonomic nervous system during recovery following a high-intensity physical activity protocol. From this aim, three hypotheses were derived: Hypothesis 1: Sound-vibration therapy significantly reduces sympathetic activity of the autonomic nervous system after a high-intensity physical activity protocol. Hypothesis 2: Sound-vibration therapy significantly increases parasympathetic activity of the autonomic nervous system after a high-intensity physical activity protocol. Hypothesis 3: Sound-vibration therapy significantly contributes to improving the speed and quality of recovery following intense sports training. In addition to the primary aim of determining the effects on the autonomic nervous system, this study investigates the effects of sound-vibration therapy on the activity of the central nervous system and subjective recovery impressions. Methodology: The methodology includes a qualitative-quantitative repeated measures experiment on the same group of trained amateur athletes subjected to intense sports training. Initial values of measured variables were recorded at the beginning of the protocol, followed by intense sports training. After completing the training, the subjects lay on a massage table for 45 minutes. In the control protocol, the subjects lay in silence during recovery, while the experimental protocol included an intervention with sound-vibration therapy under identical lying conditions. During recovery in both protocols, parameters of the central and autonomic nervous systems were measured. The subjective impression of the subjects was measured using the standardized Subjective Exercise Experiences Scale (SEES) and an additional subjective impression questionnaire, with personal descriptions evaluated descriptively and included as an appendix to the quantitative results. The Kolmogorov-Smirnov test was used to check the normality of the distribution of all variables. If a particular distribution was normal, data for that variable were presented as arithmetic means and standard deviations. If the data did not follow the normality of the Gaussian curve, data presentation was defined through medians and interquartile ranges (25th and 75th percentile). Data were analyzed using ANOVA for repeated measures to compare all points, and pairs of variables in case of confirmed significance. Also, pairs of variables before and after the intervention were tested using the Student's t-test for dependent samples or the Wilcoxon rank sum test for non-parametric statistics with a set significance level of p<0.05. The impact of the intervention was checked by calculating the effect size (Cohen's effect) and defined as small, moderate, or large. All analyses in this doctoral dissertation were conducted using SPSS version 23. Results: Although some trends were observed, the results did not show significant changes in the function of the central nervous system under the experimental protocol. On the other hand, the autonomic nervous system showed significant differences in the direction of increased parasympathetic activity, enhanced vagal tone, and reduced sympathetic influence during sound-vibration therapy compared to the protocol without its application. The assessment of subjective impressions using the SEES scale and the subjective impression questionnaire clearly indicated positive experiences towards recovery, qualitatively confirming the obtained quantitative findings. Conclusion: The analysis concluded that sound-vibration therapy with Tibetan singing bowls significantly contributes to a faster return of the autonomic nervous system to a stable state after intense physical activity by reducing sympathetic and increasing vagal influence, thus creating conditions for a higher quality and faster recovery of activated body systems. The impact of sound-vibration therapy (SVT) did not show a significant effect on the central nervous system. This is due to the rapid natural normalization of measured EEG activity, as it is not possible to conduct an intervention and measurements within the short period that offers stabilization of brain activity parameters (up to 6 minutes). Since central nervous system activity is not a relevant marker of recovery after intense sports activity, the lack of significant intervention impact did not affect the validation of the researched recovery using SVT. Furthermore, reviewing the results obtained from the SEES scale measurements and the descriptions of individual subjective experiences, the application of SVT significantly increased experience of personal well-being and reduced experience of fatigue and psychological distress after intense sports training. Theoretical and Practical Implications: This research is one of the first of its kind, making a step forward in exploring recovery techniques. Evidence of the effectiveness and practical applicability of this type of therapy suggests its use in practice for the purpose of better recovery, improved sports performance, injury prevention, and overall enhancement of athletes' quality of life.
