ABSTRACT

Introduction:

Wrestling is an ancient combat sport, individual and of complex performance, which integrates high technical and tactical complexity, associated with a bioenergetic interaction and a high coordinative pattern. In Brazil, the number of competitors at different levels has increased significantly in the last years, evidencing the need to search for answers that can help coaches in the different situations of the competitive calendar. The prescription of the means and methods of training in Greco-Roman wrestling aims at the development of the technical effectiveness. However, there is no evidence of indicators of technical effectiveness, in Brazilian elite athletes of Greco-Roman wrestling, in national and international competitions.

Objectives:

The objective of the study was to verify and to compare the technical effectiveness of the wrestlers of Greco-Roman fight of the Brazilian selection, in two competitions: one in the national level and the other international.

Methods:

Seven athletes of the Brazilian wrestling team participated of the investigation (age: 25±5 years; stature: 175±12 cm; corporal mass: 80± 21kg). Analysis of the effective, not effective and total technique were accomplished. After identifying the normality of the data (SHAPIRO WILKS), the Student's t test was used to compare the variables, according to the moment evaluated, considering the significance level of 5%.

Results:

The results showed a significant decrease (p = 0.03) in the standing effective technique and in the total effective technique (p = 0.01), comparing the national competition with the international competition.

Conclusion:

Technical effectiveness of Brazilian wrestlers was found to be below the indices presented in studies with competitors from countries considered to have high world performance. In international competition, it presents a negative impact compared to national events. Level of Evidence IV; Therapeutic Studies - Investigation of Treatment Results.
