1. Introduction
As nearly half of all boys and one third of all girls sustain at least one fracture during growth [1–3], strategies to reduce fracture risk are important. Bone mass, bone structure, neuromuscular function, and muscle strength are traits that in adults are known to affect fracture and/ or fall risks [4–6]. Previous physical activity (PA) intervention studies have found that these traits can be improved in children and that pediatric fracture risk then may be reduced [7–10]. Also, studies suggest that there might be a sex difference in the response to PA [11,12], which highlights the importance of sex-specific evaluations. In previous Pediatric Osteoporosis Prevention (POP) studies we have reported that the school-based PA intervention program enhances the gain in bone mass and muscle strength in children of both sexes in a short-term perspective [13,14]. However, with extension of the program, the benefits seemed to gradually attenuate so that after seven years (when the children were in puberty) no residual effects were seen in boys and only some benefits remained in girls [11]. The sex difference may partly be explained by the fact that since girls mature before boys they may reduce their PA levels earlier than boys [15–17]. In girls the intervention will thus contribute relatively more to the total amount of PA and therefore have a larger impact than in boys. These recent findings urge further extension of the study to determine whether, as they get older, all musculoskeletal benefits will disappear in girls too. The aim of this study was to sex-specifically evaluate the effects of the extension of the previously reported exercise intervention program [11] on the gain in bone mass, bone size, muscle strength, and fracture risk. Since there seem to be sex differences in PA levels during growth [15–17] we hypothesized that the extension would continue to have greater effects in girls than in boys, but that fracture risk reduction would still be evident in both sexes with each additional year of extra PA. Furthermore, we hypothesized that the fracture risk reduction could be a result of gains in bone mass and muscle strength, but that other PA-improved endpoint variables not evaluated by this paper also could have effects.
