Efeito da utilização do coringa no treinamento em campo reduzido em jogadores de futebol universitário

Soccer is the most popular sport in Brazil and one of the most popular in the world. Within this context, the practice of university soccer has increased the number of practitioners. A methodology widely used in the training of high performance teams are games reduced field ( JCR). The objective of this study was to evaluate the intensity of physical effort of football players during a small side game, 4x4, check the correlation between [La], HR PSE and the players and the floater influence on the intensity of the small side game. We analyzed eight players of UNESP in Bauru mean age 21.2+1.5 years, weight 75.8+11.6 kg, height 1.77±8cm, body fat percentage 12.3+5.5%, VO2max 37.1 ml/kg/min. The training was performed in 4 x 6 min with an interval of between one minute for recovery. The [La] and PSE were collected between the second and third time and after the end of training, the HR was measured every five seconds throughout the training through the RS400 heart rate monitor. A training session player floater participation (4x4+1) and the other not (4x4). The results presented showed no correlation with the HR [La] and PSE. HR significantly different, being 157+10 in the game 4x4+1 and 146+13 in the game 4x4. The percentage of HRmax in the game with floater was 81.3% and 75.7% in the game without. The players were most of the time in a higher intensity in the JCR with a floater, 37.8% of playing time over 85% HRmax, and 22.5% of playing time over 85% of HRmax in the JCR without floater, demonstrating that the use of a floater player made the game more intense and efficient to increase the intensity of the game

Immediate loading of implants installed in a healed alveolar bony ridge or immediately after tooth extraction: an experimental study in dogs

ObjectiveTo compare the sequential healing at immediately loaded implants installed in a healed alveolar bony ridge or immediately after tooth extraction.Material and methodsIn the mandible of 12 dogs, the second premolars were extracted. After 3months, the mesial roots of the third premolars were endodontically treated and the distal roots extracted. Implants were placed immediately into the extraction sockets (test) and in the second premolar region (control). Crowns were applied at the second and third maxillary premolars, and healing abutments of appropriate length were applied at both implants placed in the mandible and adapted to allow occlusal contacts with the crowns in the maxilla. The time of surgery and time of sacrifices were planned in such a way to obtain biopsies representing the healing after 1 and 2weeks and 1 and 3months. Ground sections were prepared for histological analyses.ResultsAt the control sites, a resorption of the buccal bone of 1mm was found after 1week and remained stable thereafter. At the test sites, the resorption was 0.4mm at 1-week period and further loss was observed after 1month. The height of the peri-implant soft tissue was 3.8mm both at test and control sites. Higher values of mineralized bone-to-implant contact and bone density were seen at the controls compared with the test sites. The differences, however, were not statistically significant.ConclusionsDifferent patterns of sequential early healing were found at implants installed in healed alveolar bone or in alveolar sockets immediately after tooth extractions. However, three months after implant installation, no statistically significant differences were found for the hard- and soft-tissue dimensions.

Reator anaeróbio compartimentado para o tratamento de águas residuárias de suinocultura

Water and soil pollution caused by the waste from the swine production causes severe environmental impacts in producing areas. An efficient alternative to reduce these impacts can be the use of high-rate anaerobic reactors. In this work, it was evaluated the effect of the swine wastewater with total suspended solids concentrations around 6.000 mg.L-1 in the anaerobic baffled reactor with three compartments. The volume of the first compartment was 210 L and of the second and third ones of 160 L. The anaerobic baffled reactor was submitted at hydraulic detention times of 56, 28 and 18 hours and to organic load rates of 5.0 to 10.1 g total COD (L.d)(-1). The highest total COD removals, of 42 to 68%, and volumetric methane productions, of 0.261 to 0.454 L CH4 (L reactor d)(-1), occurred in the second compartment.
