Do pedometers motivate people to walk more?

Physical activity confers many important health benefits. The 'active living message' recommends that adults should accumulate 30 ruin of moderate-intensity physical activity (e.g. brisk walking) on most--preferably all--days of the week, but the populations of most developed countries are not meeting this target. Walking is one mode of activity that most people can do without skills, equipment, facilities or extra expense and walking has less bias in terms of age, sex and social class than facility-based exercise. Thus we need to investigate interventions that promote walking

Functional balance performance in aging: evidence of moderated prediction by strength and power

Age-related reductions in strength and power are considered to negatively impact balance control, but the existence of a direct association is still an issue of debate (Orr, 2010). This is possibly due to the complexity of its assessment which may involve quantitative measurements of postural sway or functional balance tasks (Granacher et al., 2012). The present work questions whether postural balance interacts with strength and power in determining functional balance performance. Fifty-seven healthy 65 to 75 year old individuals performed tests of dynamic functional balance (chair rise, walking speed under different conditions) and of strength, power and static postural balance. Results showed that functional balance performances were generally predicted by strength and power and, additionally, by postural balance when conditions required postural adjustments. Interactive effects of postural balance and strength were found, indicating that good postural balance facilitates the utilisation of strength to better perform complex functional balance tasks

The Effect of Nutrient Intake on Bone Mineral Status in Young Adults: The Northern Ireland Young Hearts Project

Aunque hemos hablado de ello, no estará de más recordar que uno de los mejores blogs de historia es el de la Historical Society. Este recién empezado año lo han inaugurado con un repaso al número que su revista, Historically Speaking, publicó a principios de 2009. Ha pasado cierto tiempo, es evidente, pero conviene detenerse en su contenido, porque no es habitual: la forma en la que escribimos  la historia. En efecto, la citada publicación dedicó una mesa redonda a debatir sobre "Teaching the..
