The tests for assessing the anaerobic capabilities of wrestlers have shortcomings; in some cases, specialized equipment is needed, and some are greatly influenced by technique or flexibility. For the purpose of more frequent testing of young wrestlers, two simple tests with a Bulgarian bag were devised: circuiting and jerking. The study included 17 young wrestlers from HK Šibenik, divided into two quality groups (group 1, 50% wins and above; group 2, less than 50% wins). They were tested using two standard and two new tests for assessing anaerobic capabilities. The newly devised tests are reliable, with a Crombach-alpha value of 0.88, and the average inter-item correlation is 0.68. The new tests have satisfactory sensitivity, which is confirmed by the descriptive statistical parameters as well as the values of the KS test. The pragmatic validity of the new tests was confirmed through a high correlation with the standard tests (the correlation coefficient ranges from 0.63 to 0.75). Although in all tests, higher-quality wrestlers achieved better results, these differences are not significant. The lack of significance can be attributed to the wider age range among the subjects; due to the different competitive systems, they cannot be properly categorized by quality. In conclusion, the newly devised tests are reliable and pragmatically valid. However, the study should be repeated with subjects of the same age group to verify differences among wrestlers of varying qualities.
