PROGNOSTICATION OF SUCCESSFULNESS IN ARM-WRESTLING ON THE BASE OF MORPHOLOGICAL FUNCTIONAL INDICATORS’ ANALYSIS

Abstract

Purpose: to work out methodic of arm wrestling successfulnessprognostication by morphological functional indicators and substantiateit.Material: 189 sportsmen (of age 21.62 +/- 0.85 years) were tested. Wefulfilled goniometric testing of arms' joints (n=27) and handdynamometry (n=50). Characteristics of physiological tremor were studied(n=29). Strength of forearm's muscles was determined (n=33) as well asthe strength of hand fingers' extensors separately (n=50).Prognostication was realized with the help of sequential procedure byWald's methodic, with calculation of prognostic coefficients and theirinformative potential.Results: prognostic table, containing functional state indicators ofarm-wrestlers. It contained 18 criteria. The criteria illustrate power,goniometric and functional indicators. Informative potential variedwithin 64.70 -6.33. The sense of prognosis is assessment of results anddetermination of appropriate prognostic coefficient. Besides, prognosisimplies summing up of these coefficients for achievement of one ofprognostic thresholds. The value of these thresholds was determined atlevel of +/- 13, that corresponds to 95% (p< 0.05) probability.Achievement of threshold + 13 and more means sportsman's successfulnesshigher level. In case of lower threshold achievement successfulnessprobability is low.Conclusions: the conducted researches permitted to work out methodic ofarm wrestling successfulness prognostication by morphological functionalindicators and substantiate it. The offered methodic is based onsequential analysis by Wald and is a simple, informative and objectivetool of arm-wrestlers' condition control.
