School-based soccer practice is an effective strategy to improve cardiovascular...
Seabra, André; Brito, João; Figueiredo, Pedro; Beirão, Liliana; Seabra, Ana; Carvalho, Maria José; Abreu, Sandra; Vale, Susana; Pedretti, AugustoWe examined the effects of a 6-month school-based soccer programme on cardiovascular (CV) and metabolic risk factors in overweight children. Methods: 40 boys [8-12 years; body mass index (BMI) >2 standard deviations of WHO reference values] participated in complementary school-based physical education classes (two sessions per week, 45-90 min each). The participants were divided into a soccer group (SG; n = 20)...
Effects of 6-month soccer and traditional physical activity programmes on body ...
Seabra, André; Katzmarzyk, Peter; Carvalho, Maria José; Seabra, Ana; Coelho-E-Silva, Manuel; Abreu, Sandra; Vale, Susana; Póvoas, SusanaPhysical activity is important in obesity prevention, but the effectiveness of different physical activity modalities remains to be determined among children. The main purpose of this study was to compare the effects of a 6-month soccer programme and a traditional physical activity programme on changes in body composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitne...
Piecing together terminology in bioarchaeology
Cruz, Cristina Barroso; Neto, Filipa; Seabra, AnaRecent data has shown that there is a great diversity of vocabulary related with bioarchaeology and funerary archaeology employed both in technical and scientific documents produced in Portugal. This phenomenon reflects, the lack of an uniform criteria in the application of concepts reflecting the circumstances and scientific preferences of the author, and as such revealing the subjectivity associated with the ...
Averaging methods for design of spacecraft hysteresis damper
Smirnov, Georgi; Gama, Ricardo; Guerman, Anna D.; Seabra, AnaThis work deals with averaging methods for dynamics of attitude stabilization systems. The operation of passive gravity-gradient attitude stabilization systems involving hysteresis rods is described by discontinuous differential equations. We apply recently developed averaging techniques for discontinuous system in order to simplify its analysis and to perform parameter optimization. The results obtained using ...
