Vigorous physical activity patterns affect bone growth during early puberty in boys
Resumen: Summary: This study aims to analyze the impact of participation in vigorous physical activity as it can promote a healthy bone development. Adolescents who increased their participation in vigorous physical activity showed higher improvements in bone parameters compared to those who did not, which highlights the relevance of vigorous physical activity engagement.
Introduction: The main purpose of the study was to analyze the effects of different patterns of vigorous physical activity (VPA) on bone development.
Methods: One-week accelerometry registers and dual-energy X-ray absorptiometry scans at the whole body, hip, and lumbar spine of 140 healthy male adolescents (11–13 years, at baseline) were performed twice with a 1-year interval between measurements. Four patterns of VPA evolution (“low–low, ” “low–high, ” “high–low, ” and “high–high”) and three patterns of bone growth (“optimal, ” “mean, ” and “reduced”) were defined according to the median participation in VPA and a cluster analysis of the longitudinal changes in BMC and BMD in all sites measured, respectively. Bone mineral parameters were adjusted for skeletal age and body weight prior to statistical comparison among groups.
Results: Participants in the “low–high” group had greater adjusted BMD increases at both the femoral neck and lumbar spine when compared to the “low–low” group (estimated mean (95% CI) 0.066 (0.047–0.085) vs. 0.034 (0.021–0.047) g/cm2 and 0.074 (0.054–0.093) vs. 0.049 (0.035–0.062) g/cm2 respectively, both p < 0.05). Femoral neck BMD adjusted increase was also different between the “high–high” and the “high–low” groups (0.053 (0.041–0.066) vs. 0.030 (0.011–0.049) g/cm2, p < 0.05). Additionally, a higher percentage of “optimal” growth was found in the “low–high” group than in the “low–low” and “high–low” categories (36.3, 12.5 and 13.6% respectively, p < 0.05).
Conclusions: Engaging in VPA as well as maintaining high levels of VPA during puberty is associated with greater gains in bone mass, which can have an impact in future bone health.
