摘要:Objective. In this work, the changes in the regional strengths during the seasonal training period of 38athletes prepared to qualification before 2016 Summer Olympic Games were analyzed. The research wasconducted on 35 male and 3 female national athletes including 9 male Greko-Roman wrestlers ( 24±4,5 years),10 male Freestyle wrestling athletes (22,10±3,21 years),8 male judokas (23,6±1.89 years), 8 male athletes(22,29±2,87 years), and 3 female athletes ( 21,67±2,08 years)Methods. The regional strength of the participating athletes were measured 3 times in total, immediatelybefore the 6-month training period, 3 months later and 6 months later. Measurement of Hand Grip Strength(HGS) of athletes was assessed using the Takei brand Hand dynamometer and back and leg strength wasmeasured by the Takei back-lift Dynamometer. To determine the difference between the measurements, the test"Analysis of variance in repeated measurements" was used. Differences in P <0,05 were considered significant.Results. Study revealed that, judokas’, Greco- Roman and freestyle wrestlers’ back and leg strength weresignificantly higher (P<0,05) on the 6th month compared to baseline and 3 month later measurements. Left andright grip strength did not reflect any statistical differences according to time measurement in all branches ofSport (P> 0,05). The strength values of female athletes showed no statistical difference between themeasurements (P> 0,05).Conclusions. Strength training, which wrestlers, judokas and male athletes were engaged in during thepreparatory period, led to an increase in the value of the back and leg strength , as they approached the period ofthe competition. However, it was observed that, even the features of strength that is important for wrestlingathletes are increased, in general, this increase is lower than expected for Olympic athletes. For this reason, itwas concluded that the athletes have to carry out more planned studies to gain strength during the preparationperiod.
