The recognition of adolescents' physical activity has become one of the serious challenges of the modern times, as a concern about the future health of societies. The major goal of the presented study was to discover the level of physical activity among Polish adolescents aged 16-18, and the factors which condition this level. The investigations were carried out in 2011, among 2,974 school adol...

I T HAS been stated, “The process of aging consists of those changes with time which result in progressive loss of abilities and in progressive increase in death rate.“’ The staff of The Benjamin Rose Hospital, a hospital for prolonged illness in Cleveland, Ohio, is making a continuing effort to establish methods for obtaining quantitative information about the progressive loss of abilities and...

The purpose of this study was to determine the effects of periodic task-specific test feedback on performance improvement in older adults undertaking community- and home-based resistance exercises (CHBRE). Fifty-two older adults (65-83 years) were assigned to a muscular perfsormance feedback group (MPG, n = 32) or a functional mobility feedback group (FMG, n = 20). Both groups received exactly ...

Cardiometabolic disease poses a serious health and economic burden worldwide and its prevalence is predicted to increase. Prolonged sitting, lack of physical activity, poor diet, and short sleep duration are ubiquitous behaviors in modern society, and all are independent risk factors in the development of cardiometabolic disease. Existing evidence demonstrates that breaking up prolonged periods...

This study measured objectively the postural physical activity of 4 groups of older adults (> or =65 yr). The participants (N = 70) comprised 3 patient groups--2 from rehabilitation wards (city n = 20, 81.8 +/- 6.7 yr; rural n = 10, 79.4 +/- 4.7 yr) and the third from a city day hospital (n = 20, 74.7 +/- 7.9 yr)--and a healthy group to provide context (n = 20, 73.7 +/- 5.5 yr). The participant...

People sometimes fail to notice salient unexpected objects when their attention is otherwise occupied, a phenomenon known as inattentional blindness. To explore individual differences in inattentional blindness, we employed both static and dynamic tasks that either presented the unexpected object away from the focus of attention (spatial) or near the focus of attention (central). We hypothesize...

In the primate brain, sensory information is processed along two partially segregated cortical streams: the ventral stream, mainly coding for objects' shape and identity, and the dorsal stream, mainly coding for objects' quantitative information (including size, number, and spatial position). Neurophysiological measures indicate that such functional segregation is present early on in infancy, a...

BACKGROUND The aim of the current investigation was to evaluate the sedentary lifestyle of the Polish population and its link with prolonged sitting in light of individual and environmental factors. METHODS The sample consisted of 1505 Polish people between 18 and 64 years old. The Computer-Assisted Telephone Interview (CATI) survey was conducted with the Polish version of International Physi...

Changes in sedentary behaviours and physical activity according to retirement status need to be better defined. Retirement is a critical life period that may influence a number of health behaviours. We assessed past-year sedentary behaviours (television, computer and reading time during leisure, occupational and domestic sitting time, in h/week) and physical activity (leisure, occupational and ...

With the growing trend in many subjects to deliver at least some part of examinations by computer, it is important to know whether there are any differences in the results obtained by candidates sitting examinations taken by computer compared to those obtained by candidates sitting conventional examinations using pen and paper. The purpose of this paper is to describe a pilot project to compare...
