- Characterization of temporal patterns of behavior of the crawl techniquePublication . Louro, Hugo; Conceição, A.; Matos, T.; Nilton, J.; Franco, R.; Camerino, O.; Campaniço, J.OBJECTIVE: With this work we want to check the standards of the crawl technique from an observational methodology appropriated.The instrument of observation (Nilton, 2008) was developed Ad Hoc, using the references of biomechanical models, based on a mixed system of categories and formats of fields, with particular reference to four criteria that add in the form of alpha-numeric codes. The results of the quality of the instrument revealed indices of reliability and high precision. METHODS: We use a sample of six swimmers from Portuguese and international level as part of the Portuguese national team in swimming. Each element was subject to the overall swimming crawl technique at a distance of 25m to achieve maximum speed without a breath. The units of observation are natural (events and behaviors) and analytical (of behavior). The detection of temporal patterns by binomial analysis (Magnusson, 2000) was made by the software 5.0 Theme created by Magnusson (1996, 2000). The instrument is intended to identify patterns which are within the critical intervals, allowing examination of the inter-relationship of temporal events (movement), using the record of occurrences in the collection of patterns found in data. RESULTS: The patterns found in each swimmer is different and each pattern is adjusted to the particular individual techniques. DISCUSSION & CONCLUSION: The same swimmer can present similar structures for implementation, representing a behavior pattern. In all the swimmers were identified more than one standard. However, it is noteworthy that no swimmer of the sample made the same overall behavior at any stage observed in the five cycles analyzed.
- Stability of patterns of behavior in the butterfly swimmers.Publication . Louro, Hugo; Silva, António José; Anguera, T.; Camerino, O.; Oliveira, C.; Conceição, A.; Campaniço, J.OBJECTIVE: The purpose of this study was to find patterns in the swimming technique of butterfly, with an adaptation of the Behavioral Observation System Tech. This, as a instrument for ad-hoc qualitative analysis enables the study of the stability of the technical implementation, an applicant in optimization sport. When used in the training of swimmers, can turn, reduce the variability in behavioral tuning technique of swimming. Through the analysis of temporal patterns (T-pattern) and a sequence of five cycles run at maximum speed hand, studied the behavior of four technical elite swimmers in Portuguese, with a record 259 alphanumeric codes and a total 160 configurations. The structure of the original instrument based on a mixed system of categories and formats Field, which can record technical features observed during the execution of hand cycles. The validity was ensured through the index of intra-observer reliability (95%) and inter-observer accuracy (96%). To detect patterns exist, each swimmer, using the Theme 5.0 software, which allowed to identify the stable structures of technical performance within a critical interval of time (P<0,05) t-patterns. RESULTS: The patterns were different, adjusting to the characteristics of technical implementation of the swimmers. Found that the swimmer can make settings with different levels of complexity of structure, depending on the implementation of changes within the hand cycle. Variations of codes in each configuration obtained using the SOCTM, determine the differences between swimmers. DISCUSSION & CONCLUSION However, the records show a clear behavioral similarity compared the result with a general pattern of the butterfly technique. Conclusion: As we can see that the potential quality of this instrument is evident by the patterns obtained from a temporal sequence.
