The Analysis Of Handgrip Strength And Somatotype Features In Arm Wrestling Athletes With Different Skill Levels

Purpose: Comparative analysis of handgrip strength and somatotype features of arm wrestling athletes with different skill levelsMaterial: The study involved 36 students and teachers practicing arm wrestling. Group 1-12, (23.92 +/- 2.11) years old (experienced athletes). Group 2-24, (24.33 +/- 1.69) years old (beginners and short experience athletes). The length and body mass were determined, the level and harmony of physical development were estimated. Handgrip strength was estimated in static mode by handgrip strength test. It was used the digital hand dynamometer CAMRY EH101 (China). The dynamic handgrip strength was determined by the maximum handgrip frequency for 10 s using Kepai digital device (China). The content of muscle, adipose tissue, and the visceral fat level was estimated using the bioimpedance method. The body mass index was also estimated. Results are estimated by applying parametric and nonparametric statistical indicators. The contribution of an individual criterion to the system was estimated by the system formation indicator.Results: It was confirmed the proximity of the physical development of participants due to the lack of significant differences in most indicators. It was determined a significant excess of the value of the handgrip strength test of the right hand in group 1 (U = 75, p <0.05). In group 1, the level of physical development prevailed above the average-(58.33 +/- 14.23)%. (58.33 +/- 14.23)% of participants in group 1 had harmonious and (41.67 +/- 14.23)% had disharmonious development. In group 2, athletes with a level of physical development above average were (37.50 +/- 9.88)%, and athletes with disharmonious physical development were (70.83 +/- 9.28)%. The average body mass index in group 1 was (26.24 +/- 0.98) kg/m(2), in group 2-(25.03 +/- 0.81) kg/m(2). The specific gravity of muscle tissue in the groups was related to the range of high values. In group 1 (25.00 +/- 12.50)% of participants had an average level of muscle tissue, (58.33 +/- 14.23)%-high level and (16.67 +/- 10.76)%-very high level. In group 2, the specific gravity of such participants was, respectively, (17.39 +/- 7.90)%, (56.52 +/- 10.34)%, and (26.09 +/- 9.16)%. The average specific gravity of adipose tissue in the groups was related to the average level. Such athletes were (66.67 +/- 13.61)% among the participants of the group 1 and (58.33 +/- 10.06)% among the participants of the group 2. The maximum contribution to the system is body mass. Their value is 64.68 c.u. (group 1) and 45.32 c.u. (group 2). The contribution of the handgrip strength test was higher in group 2-27.22 and 42.05 versus 13.43 and 21.55. The values of the system formation indicators of the handgrip frequency in the pulsed mode were higher among experienced athletes: 12.17 and 12.71 versus 0.68 and 0.68.Conclusions: The persons with a level of physical development above the average prevail among athletes. The disharmony of physical development is due to an increase in body mass compared to standards of physical development. This is due to an increase in the specific gravity of muscle tissue. The proximity of the indicators is the result of specialized training in arm wrestling. Athletes have increased content of muscle tissue; the specific gravity of adipose tissue was within the age limits. The handgrip strength test was higher in experienced athletes. The value of the contribution of the handgrip strength in pulsed mode to the system allows considering them important for success in arm wrestling. The application of the bioimpedance method has significantly expanded the obtained data in the analysis of anthropometric indicators and indices. This method can be recommended for monitoring the functional condition of arm wrestling athletes.
