Este ar tigo evidencia as contradições do Modelo Cooperativista brasileiro em relação ao Modelo Original. Trata- se de incoerências intrínsecas na formação do movimento cooperativo, nos princípios para a sua condução ideológica, bem como na regimentação e operacionalização estatutária. A partir desses desacertos, o artigo mostra as restrições para o exercício da autogestão. Também sugere mudanças nas leis cooperativistas vigentes, propícias ao exercício da participação dos associados no processo decisório.

The main purpose of this study was to analyze the effect of the pedaling cadence (500 × 100 rpm) on the heart rate (HR) and the blood lactate response during incremental and constant workload exercises in active individuals. Nine active male individuals (20.9 ± 2.9 years old; 73.9 ± 6.5 kg; 1.79 ± 0.9 m) were submitted to two incremental tests, and to 6-8 constant workload tests to determine the intensity corresponding to the maximal steady state lactate (MLSSintens) in both cadences. The maximal power (Pmax) attained during the incremental test, and the MLSSintens were significantly lower at 100 rpm (240.9 ± 12.6 W; 148.1 ± 154.W) compared to 50 rpm (263.9 ± 18.6 W; 186.1 ± 21.2 W), respectively. The HRmax did not change between cadences (50 rpm = 191.1 ± 8.8 bpm; 100 rpm = 192.6 ± 9.9 bpm). Regardless the cadence, the HRmax percentage (70, 80, 90, and 100%) determined the same lactate concentrations during the incremental test. However, when the intensity was expressed in Pmax percentage or in absolute power, the lactate and the HR values were always higher at highest cadences. The HR corresponding to MLSSintens was similar between cadences (50 rpm = 162.5 ± 9.1 bpm; 100 rpm = 160.4 ± 9.2 bpm). Based on these results, it can be conclude that regardless the cadence employed (50 × 100 rpm), the use of the HR to individualize the exercise intensity indicates similar blood lactate responses, and this relationship is also kept in the exercise of constant intensity performed at MLSSintens. On the other hand, the use of the Pmax percentages depend on the cadence used, indicating different physiological responses to a same percentage.

In order to evaluate the influence of exercise of different intensities on Red Blood Cell Distribution width (RDW) and Packed Cell Volume (VG) in Thoroughbred horses, blood was collected from 60 animals, 30 males and 30 females, subdivided in groups of horses with 24 to 36 months of age and not in training, and after 12 months of training, and horses with 36 to 48 months of age in training. Blood samples where collected before and after trot and gallop. Samples where analyzed with a automatic cell counter (Cell-Dyn 3500R, Abbott Diagnostic). Red Blood Cell Distribution width (RDW) values increased significantly after trot and gallop demonstrating a variation in the size of red blood cells, while Packed Medium Cell Volume (VGM) values did not show variations before or after exercise.
