Osteogenic effects associated with a municipal physical exercise programme in a group of Spanish Caucasian adults
摘要
In accordance with the latest WHO guidelines, the Castellón City Council Sports Board periodically designs physical exercise programmes aimed at adult people in order to increase their health and fitness. In keeping with this goal, this study was designed to analyse the changes that one of these programmes could induce on weight, body mass index (BMI) and body composition (fat mass, lean mass and bone mineral component) of the subjects who carried it out.
MethodsObservational and longitudinal study in which the DXA scan results (weight, BMI, fat mass, lean mass and bone mineral component) from 328 Spanish Caucasian adults (241 women), obtained before and after an annual physical exercise programme without dietary control [athletic men (AM) and women (AW)], were analysed and compared with those from 207 sedentary controls (120 women) [sedentary men (SM) and women (SW)].The normality test were used for the analysis of variables.
ResultsThe results showed a significant increase in bone mineral component (bone mineral density and T-score) in AM and AW, whereas a decrease was observed in SM and SW. No significant changes were observed in weight, BMI, fat mass, or lean mass.
ConclusionThe exercise programme was associated with improvements in bone mineral component in both groups of athletes, whereas no such improvements were observed in the sedentary groups. No associations were observed between the exercise programme and changes in weight, fat mass, or muscle mass.
