| ABSTRACT | |||
| The
purpose of this study was to find patterns in the butterfly swimming technique,
with an adaptation of the Behavioral Observation System Tech. This, as an
instrument for ad-hoc qualitative analysis, enables the study of the stability
of the technical implementation. When used in the training of swimmers,
analysis can reduce the variability of behavioral tuning swimming technique.
Through the analysis of temporal patterns (T-pattern) and a sequence of
five cycles running at hand maximum speed, the behavior of four technical
Portuguese elite swimmers, with a record of 259 alphanumeric codes and a
total of 160 configurations, were studied. The structure of the original
instrument, based on a mixed system of categories and formats Field, 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 in each swimmer,
the Theme 5.0 software was used, which allowed to identify the stable structures
of technical performance within a critical interval of time (p <0.05)
- t-patterns. The patterns were different, adjusting to the characteristics
of technical implementation of the swimmers. It was found that the swimmer
can create settings with different levels of structure complexity, depending
on the implementation of changes within the hand cycle. Variations of codes
in each configuration obtained using the SOCTM, allowed determining the
differences between swimmers. However, the records showed a clear behavioral
similarity when comparing the result with a general pattern of the butterfly
technique. The potential quality of this instrument seems to be important
due to the patterns obtained from a temporal sequence. Key words: Technical analysis, patterns, butterfly, chronology. |
