Opis:
The purpose of this study was to determine how global effort affects the rhythm of multi-joint coordination in the global task. We wanted to examine how this specific kind of fatigue impacts sense of rhythm. Methods: In this study, fourteen non-professsional runners performed two effort trials of different intensity, where speed was set individually according to the speed of running when participants reached lactate threshold. Before and after each effort trial they had to perform the rhythm test. Results: Two-way analysis of variance ANOVA did not reveal significant differences among the variables of pre- and post-effort rhythm test. It is suggested that these results are supported by the application of different movement strategies to compensate for fatigue, and possible motor learning effect of simple timing performance. Conclusions: In our opinion the training workout routine should include cyclic technical exercises after fatigue. Not only to develop and improve energetics of movement, but also to learn and perfect different movement patterns and develop novel movement strategies.

Opis:
The objective of this study was to evaluate the reliability and validity of two alternative systems used for jumping performance measurement. Methods: Two groups of subjects were tested. The first group consisted of 15 male adults (21.3 ± 1.7 years ) and the second group consisted of 16 female volleyball players (17.2 ± 0.9 years). We used three different systems of data collection in the study. Two of the used systems are based on optoelectric components. The Optojump Next system is referred to as the optoelectric system, and BTS Smart-E is refered to as the video system. Concurrent validity of these systems was verified with the use of “gold standard” which is force platform. All systems were used to estimate the height of vertical jumps. Results: Both optoelectric systems occurred to be highly reliable with the ICCs=0.98 for Optojump and 0.9 for BTS Smart. Their concurrent validity with the force platform data was also very high r=0.99 and r=0.97 respectively. Conclusions: Comparison of these two systems shows distinct differences between them where Optojump system is more suitable for quick and reliable sports testing, when BTS-Smart for research and clinical testing.
