Biological relation and the predictive possibilities between the morpho-functional and the voice-acoustic parameters

BACKGROUND: Since the human being functions as a multidimensional system with highly adaptable automatic features and with strong correlations among the subsystems, the scientists have been encouraged to explore the predictive possibilities of one human characteristic/ability according to different morpho-functional characteristics/abilities. The goal of this study was to explore the biological relations between morpho-functional variables and the voice-acoustic parameters, and the possibility to predict the explosive power of the lower extremities based on the registered voice acoustic parameters. METHODS: Seven morpho-functional variables and six voice-acoustic parameters were measured on 37 male athletes aged 15-29 years. The statistical analysis was accomplished through the SPSS-program version-20 and Statistica-12. The obtained data were analyzed through Canonical Analyses, Regressive Analyses, and t-test for Paired Samples. RESULTS: Canonical analysis has enabled the extraction of one significant canonical root (P=0.043), which explains 73.7% of the shared variance. The results of regression analysis indicate that the system of voice-acoustic parameters significantly predicts 34.7% of total variance of the criterion variable Margarita-Kalamen test. CONCLUSIONS: The final results of this study confirm very close biological relations between morpho-functional and voice-acoustic parameters. Additionally, according to these results, it might be suggested that based on the voice-acoustic parameters: MeanF0 and MinF0, may be predicted the athlete's explosive power of the lower extremities.
