Figure 1From: The frequency of osteogenic activities and the pattern of intermittence between periods of physical activity and sedentary behaviour affects bone mineral content: the cross-sectional NHANES study Schematic representation of the temporal pattern of intermittence between periods of activity (black) and sedentary behaviours (white). In pattern a) activity is distributed more evenly in time (high α) than in pattern b) where they are more clustered and inter-spaced with longer periods of sedentary behaviour (low α).Back to article page
