Why do birds sing? In many species, because the song attracts or retains a mate. Why do females pay attention? This paper reviews evidence that females may do so because male song can be an honest indicator of attributes of a male's brain that could contribute to his fitness or that of his young. Male songbirds learn and produce their songs using a set of brain regions collectively known as the...

Children with Developmental Coordination Disorder (DCD) experience considerable difficulties coordinating and controlling their body movements during functional motor tasks. Thus, it is not surprising that children with DCD do not perform well on tests of physical fitness. The aim of this study was to determine whether deficits in motor coordination influence the ability of children with DCD to...

BACKGROUND The aim of this study was to investigate the effects of environmental factors on physical fitness of rural and urban children. METHODS To reveal the differences between physical fitness of children living in urban and rural districts of the Turkish Cypriot population, 3939 nine- to eleven-year-old male primary school children from 90 schools of North Cyprus were tested. Testing pro...

Many school-based physical activity (PA) interventions have been developed, but only a few have assessed their long-term effects. A PA intervention taking place in the first four years of some Slovenian primary schools entails an enhanced physical education (PE) curriculum, including two extra lessons of PE per week, a wider selection of PE content, and additional outdoor education delivered by...

The article examines the peculiarities of level physical fitness girls aged 11-15 who have postural disorders. A comparative characterization indicators motor readiness with and without disorders was also carried out. influence activity on formation correct posture improvement health studied. content concept "posture disorders" analyzed it established that is an important comprehensive indicato...

People with intellectual disabilities (ID) have high rates of overweight and obesity, heart metabolic diseases, low motor development. These factors compromise functional independence autonomy in activities daily living. The objective this study was to clarify the design implementation multicomponent physical exercise programs (MPEPs) evaluate their effects on fitness people ID. A search for sc...

BACKGROUND The preschool years are a crucial time to study the determinants of childhood obesity, as it is when eating and physical activity habits are becoming established. The purpose of this study was to compare the prevalence of overweight and obesity among preschoolers living in the capital of Iran and to determine relationships between overweight and obesity and selected motor- and health...

It has been established that the health and physical fitness of non-physical education students are most important components potential entire society. Currently, in educational institutions is practically relegated to last plan, it not surprising level children youth assessed as extremely unsatisfactory. The low worsens their adaptation regime future work, especially conditions military servic...

This paper introduces the MannFitTMSystem ᛗ0 0 0 0 0 0 1 1 10 10 001 1 0001101 1 0 1 0 1 1 1 , a physical fitness concept, regimen, philosophy, and praxis, based on Integral Kinematics (e.g. time integrals of distance or displacement), rather than the Differential Kinematics (distance and its derivatives: speeed, acceleration, etc.) that are commonly used in fitness, gaming, sports, and the lik...

Abstract In order to design a solid rocket motor with high mass ratio, it is necessary find out the parameters of grain shape meet structural strength under volume loading fraction condition. A rapid optimization method for complex motors based on parametric modeling and GA-BP proposed. Based this, neural network prediction results are optimized as function fitness in GA, show that maximum Von ...
