Three studies examined the claim that hand movements can facilitate imagery for object rotations but that this facilitation depends on people's model of the situation. In Experiment 1, physically turning a block without vision reduced mental rotation times compared with imagining the same rotation without bodily movement. In Experiment 2, pulling a string from a spool facilitated participants' ...

BACKGROUND The decline of physical activity (PA) and the increased prevalence of overweight and obese children have been discussed worldwide. This study assessed the trends in the prevalence of overweight and obesity, PA and sedentary behaviour in Czech school-aged children. METHODS A cross-sectional questionnaire from the Czech Republic was administered in cycles in 2002, 2006 and 2010 under...

This study investigated whether the interaction with objects could be modulated by the real presence of another person. We used a “joint paradigm” in which participants performed the task while another person was just sitting in front of them (Social condition) or interacting with them (Joint condition). Kinematics measures showed how comprehending sentences referring to objects and to others i...

The purpose of this study is to examine the reciprocal relationship between motor abilities and physical activity and the mediation effects of physical self-concept in this relationship using longitudinal data. We expect that the effects of motor abilities on physical activity are rather indirect via physical self-concept and that the effects of physical activity on motor abilities are rather d...

Based on heights, weights, chest girths and sitting heights of about 80,000 school children aged 6-14 in Kyoto city measured at the periodic school health examinations in April of 1966, the correlations and some of the partial correlations among these four physical variables and the regression of weight on other physical variables were presented for every age group of boys and girls. The correl...

All types of dementia involve mental decline that: • occurred from a higher level (for example, the person didn’t always have a poor memory) • is severe enough to interfere with usual activities and daily life • affects more than one of the following four core mental abilities • recent memory (the ability to learn and recall new information) • language (the ability to write or speak, or to unde...

purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...

Pedometer-determined physical activity (PA) levels in Belgian adults were provided and compared to PA scores reported in the International Physical Activity Questionnaire (IPAQ). The representative sample (N=1239) of the Belgian population took on average 9655 (4526) steps/day. According to pedometer indices 58.4% were insufficiently active. Steps/day differed significantly between gender (F = ...

PURPOSE This study explored definitions of sedentary behavior and examined the relationship between sitting time and physical inactivity using the sitting items from the International Physical Activity Questionnaire (IPAQ). METHODS Participants (N = 289, 44.6% male, mean age = 35.93) from 3 countries completed self-administered long- and short-IPAQ sitting items. Participants wore acceleromet...

Peptides derived from dietary proteins, have been reported to display significant antioxidant activity, which may exert notably beneficial effects in promoting human health and in food processing. Recently, much research has focused on the generation, separation, purification and identification of novel peptides from various protein sources. Some researchers have tried to discover the structura...
