Positive Health Outcomes

Physical activity (PA) among children is positively correlated to several positive health outcomes. Although school time constitutes an important arena for children’s PA level because it includes all children, research in this area in Nordic countries remains limited. The aim of the present study is to investigate school-time’s contribution to both children’s total PA and fulfilment of health recommendations for PA. In total, 320 seventh-grade children volunteered to participate in the study, of which 291 provided valid accelerometer data and were included in the analyses. The results show that school time accounts for 30.6% and 26%, respectively, of boys’ and girls’ total moderate- and vigorous-PA (MVPA) during the week, and for 45.9% and 36.6%, respectively, of the MVPA that children need to fulfil the health recommendations. In addition, boys achieved significantly more MVPA than girls during school time, and school-time’s contribution to the fulfilment of the health recommendations for PA was significantly greater among boys than girls. The findings indicate that PA in school time possesses an unrealized potential to substantially increase children’s weekly PA. Possible strategies for increasing school-time’s contribution to children’s PA level, in general, and girls’ PA level, in particular, are discussed.

Adherence to lifestyle changes - beginning to exercise, for example - is assumed to be mediated by self-referent thoughts. This paper describes a pilot study and three studies conducted to develop and validate a questionnaire for adults to determine their self-perceptions related to health-oriented exercise. The pilot study identified items pertinent to the domains considered important in this context, and began the process of selecting items. Study 2 examined the factor structure, reduced the number of items, determined the internal consistency of the factors, and explored the discriminative validity of the questionnaire as to physical activity level and gender. Four factors with a total of 24 items were accepted, measuring mastery of exercise, body perception, social comfort/discomfort in the exercise setting, and perception of fitness. All subscales had acceptable internal consistencies. Preliminary validity was demonstrated by confirming hypothesized differences in scores as to gender, age, and physical activity level. The third study examined and demonstrated convergent validity with similar existing subscales. The fourth study examined an English-language version of the questionnaire, confirming the existence of the factors and providing preliminary psychometric evidence of the viability of the questionnaire.

Background: A decrease in the physical activity level in old age is common, which results in an increase in the number of falls and chronic conditions. Associated with that occurs the decline in motor skills as a result of the deficit in the interaction of cognitive and motor processes. Physical activity level can be associated differently with each motor domains. Objective: We analyzed the relationship between physical activity level and motor aptitude, and to identify which motor domains were most sensitive to detect insufficiently active level in older adults. Methods: Participated in the study 385 elderly people of both sexes. For the evaluation of the subjects were adopted the International Questionnaire on Physical Activity and the Motor Scale for Older Adults. Results: The majority of the elderly were active. In the comparison of motor aptitude between active and insufficiently active (IAC) elders a significant difference was found in the Global Coordination, Balance, Body Scheme and General Motor Aptitude. From the analysis of the area under the curve (AUC), we verified that these domains also were the ones that presented adequate diagnostic accuracy to identify IAC elderly. Besides that active elderly have presented the General Motor Aptitude classified within normality while the IAC below the normal. Conclusion: Our data suggest that IAC older adults present lower motor aptitude than the active elderly, especially in the domains of Global Coordination, Balance, Body Scheme and General Motor Aptitude, and that these domains were sensitive to indicate IAC older adults.
