These results suggest that AAS could be a possible new risk factor for TAFLD. In this type of fatty liver disease, the individuals had a low body fat mass and they did not present insulin resistance.

Objective: The study aimed to determine the association between postural changes and practice of classical ballet among ballerinas from Integrated Administrative Region of Development (RIDE) in Polo Petrolina/PE and Juazeiro/BA. Methods: Cross-sectional observational study with 19 classical ballerinas aged over 15 years and at least 5 years of uninterrupted classical ballet practice. The anthropometric assessment included measurements of total body mass, height and body mass index (BMI). Postural evaluation was performed using the photogrammetric method with help of Posturograma ® and SAPO © software. Results: The mean age was 25.3±11.7 years and the mean BMI was 21.4±2.9 kg/m². Approximately 74% of classical ballerinas had normal anthropometric profile. The postural profile of the classical ballerinas showed inclination and protrusion of the head, trunk rotation, rectification of cervical lordosis, increased thoracic kyphosis, increased lumbar lordosis, pelvic inclination and anteversion. Conclusion: The practice of ballet led to changes in body alignment of the classical ballerinas evaluated. The results points out to the need of postural re-education in order to contribute for the kinetic-functional balance of classical ballet practitioners.Keywords: Dancing; Posture; Photogrammetry; Spine; Body Mass Index. RESUMO objetivo: o estudo teve como objetivo verificar a associação entre alterações posturais e a prática do balé clássico em bailarinas da região administrativa integrada de desenvolvimento (ride) do

Objective: the objective was to assess the level of physical activity (LPA) and the quality of life QL of the professionals who work in ICU. Method: this was a cross-sectional study carried out in Adult ICUs. LPA was assessed by the International Questionnarie of Physical Activity -short form (IQPA-SF) and the QL by the Medical Outcomes Study 36 (SF-36) questionnaire. Results: it was classifi ed active 50.89% out of a total of 59 professionals. Nursing technicians were considered the most active with 60.6%. The QL of the professionals who were considered active were better when compared to inactives, with statistical differences to the category of physical aspects limitation, social aspects and mental health. The working hours were higher than recommend, the physicians were higher than the physical therapist, nurses and technicians nurses (p=0.046). Conclusion: physically active professionals who work in ICU had higher quality of life probably why have lower hours of work and consequently more free time to engage in physical activity.

SummaryBackground: Aerobic exercise is an important ally in the fight against cardiovascular risk factors. However, the effects of high-intensity exercise on these factors are still poorly known.

The purpose of this study was to characterize aerobic, anaerobic, handgrip strength, and body fat content (BF) characteristics in paralympic rowers (ROW) in order to determine motor disabled rowers' fitness level and if specific motor disabilities could impair performance in this specific population. Upper body anaerobic threshold (LacT), peak (PK-AnP), mean (M-AnP), and lower (L-AnP) anaerobic power, peak anaerobic power to weight ratio (RelPk-AnP) and fatigue index (FI) were measured by the Wingate test (WinT). Handgrip strength was also measured and skinfold sum was used to estimate BF and were compared with a reference group of recreational disabled athletes (CON). LacT was significantly higher (p < 0.01) in ROW compared with CON. RelPk-AnP and BF were significantly different (p < 0.05) in ROW compared with CON as well. All other measured parameters did not significantly differ between ROW and CON. In most of cases, rowers have shown a relative low performance level, induced probably by specific disabilities.

Predicting one repetition maximum equations accuracy in paralympic rowers Resistance training intensity is prescribed using percentiles of the maximum strength, defined as the maximum tension generated for a muscle or muscular group. This value is found through the application of the one maximal repetition (1RM) test. One maximal repetition test demands time and still is not appropriate for some populations because of the risk it offers. In recent years, the prediction of maximal strength, through predicting equations, has been used to prevent the inconveniences of the 1RM test. The purpose of this study was to verify the accuracy of 12 1RM predicting equations for disabled rowers. Nine male paralympic rowers (7 one-leg amputated rowers and 2 cerebral paralyzed rowers; age, 30 +/- 7.9 years; height, 175.1 +/- 5.9 cm; weight, 69 +/- 13.6 kg) performed 1RM test for lying T-bar row and flat barbell bench press exercises to determine upper-body strength and leg press exercise to determine lower-body strength. One maximal repetition test was performed, and based on submaximal repetitions loads, several linear and exponential equations models were tested with regard of their accuracy. We did not find statistical differences for lying T-bar row and bench press exercises between measured and predicted 1RM values (p = 0.84 and 0.23 for lying T-bar row and flat barbell bench press, respectively); however, leg press exercise reached a high significant difference between measured and predicted values (p < 0.01). In conclusion, rowers with motor disabilities tolerate 1RM testing procedures, and predicting 1RM equations are accurate for bench press and lying T-bar row, but not for leg press, in this kind of athlete.
