Background:
An increased occurrence of lifestyle-related diseases such as osteoporosis indicates the necessity for taking preventive action, including regularly engaging in physical activity. The aim of the study was to assess the areal bone mineral density (aBMD) and bone turnover markers levels in young adult women engaging in recreational horseback riding and to determine the relationship between training characteristics and bone metabolism indices.
Methods:
The study involved 43 women: 23 equestrians and 20 age- and body mass index–matched controls. The hip and spine aBMD and serum levels of the bone turnover markers: osteocalcin and collagen type I cross-linked C-telopeptide were measured.
Results:
No significant differences were found in somatic features, concentrations of bone turnover markers, or bone mass variables. Correlation analysis of the equestrian participants showed significant relationship between body mass and BMDL1–L4 (P < .05) as well as between BMI and BMDL1–L4 (P ≤ .01) and z-score L1–L4 (P < .05).
Conclusions:
The study showed no differences in bone mass and levels of bone metabolic indices between groups of women practicing horseback riding at the recreational level and subjects who do not participate in frequent systematic physical activity. No relationship between training characteristics and bone turnover markers were found.
