Physical exercise induces hemodynamic/ventilatory and neuromuscular adaptations that can be reverted with interruption of the training program. The aim of the present study was to evaluate the effect of detraining on physical fitness related to health. Forty-four healthy subjects, both male and female, aged 57.6±8.9 years performed the 'Mexa-se Pró-Saúde' protocol with nutritional orientation and supervised physical exercises for nine months. The program consisted of aerobic, localized muscular endurance and flexibility exercises, with duration 80 minutes/session, five days/week. Only subjects who participated in the program for more than three days/week have been selected. The detraining period was one month. Weight (kg) and height (m) were measured and the body mass index (BMI) calculated. Additionally, motors tests to evaluate the flexibility (FLEX), strength of lower limbs (SLL) and upper limbs (SUL), and maximal oxygen uptake (VO2máx) were conducted in the beginning of the study (MI), after nine months of practicing (MT) and after detraining period (MD). ANOVA (p<0.05) and Tukey test to show the difference between groups when it evidence were used for statistical treatment. The results showed that the gains of 22% and 7% on SLL and VO2máx respectively, obtained with the training, have not changed during the detraining period; however, the flexibility gain of 8% returned back to baseline after the detraining period. BMI and SUL did not change during the study. Although the lower limbs strength gains and maximal oxygen uptake obtained have been kept, one month of detraining was enough for losing the flexibility acquired.

The indwelling urethral catheter has an important role for patients with urinary retention, bladder obstruction, neurological damage and other diseases. Urine contains minerals which precipitate in alkaline pH, crystallize and block the urological catheter. The crystallization of the ionic components of urine occurs in the presence of urease, an enzyme produced by Proteus mirabilis. This bacterium adheres to inanimate surfaces and forms biofilms. The aim of this study was to investigate the formation of crystalline biofilm on the luminal surface of siliconized latex catheters by means of scanning electron microscope, after channeling artificial urine infected with Proteus mirabilis. The experiment was performed in vitro using a dynamic flow system. The artificial urine compounds were salts of calcium, magnesium, phosphates, urea and egg albumin, and it was infected with Proteus mirabilis ATCC 25933. The urine flow was stopped after crystallization of the ionic components. Crystallization was observed after alkalinization of urine. Scanning electron microscopy showed the presence of crystals and morphologies typical of bacilli embedded in an amorphous mass on the internal lumen of the catheter. The present study showed that catheter encrustation may limit the use of long-term indwelling catheter. © SBEB - Sociedade Brasileira de Engenharia Biomédica.
