Description
An account of the resource
OBJECTIVE: To evaluate bone mineral density (BMD) in perimenopausal competitive runners with long-term follow-up. STUDY DESIGN: Fifteen master female runners between 40 and 50 years old who ran at least 20 miles per week were evaluated. BMD was measured by dual-energy x-ray absorptiometry (DEXA) at baseline and at the 10-year follow-up. RESULTS: The median age was 46 and median miles run per week, 25. At baseline, after a median of 11 years of competitive running, hip BMD was above peak bone mass (T-score = 0.8) and that of age-matched controls (Z-score = 1.6), while lumbar spine BMD was below peak bone mass (T-score = -0.8) and equal to that of age-matched controls (Z-score = -0.1). At the 10-year follow-up, hip BMD fell below peak bone mass (T-score = -0.2, p = 0.0004) but was still above that of age-matched controls (Z-score = 0.5, p = 0.002), while there was little change in lumbar spine BMD. CONCLUSION: Competitive running prior to the perimenopausal period seems to be associated with improved hip BMD. However, continued competitive running during the perimenopausal period is not associated with prevention of a perimenopausal hip BMD decline. In contrast, competitive running had little effect on peri-menopausal lumbar spine BMD.

Description
An account of the resource
The primary aim of this study is to broadly evaluate the relationship between cursoriality (i.e. anatomical and physiological specialization for running) and limb bone morphology in lagomorphs. Relative to most previous studies of cursoriality, our focus on a size-restricted, taxonomically narrow group of mammals permits us to evaluate the degree to which 'cursorial specialization' affects locomotor anatomy independently of broader allometric and phylogenetic trends that might obscure such a relationship. We collected linear morphometrics and muCT data on 737 limb bones covering three lagomorph species that differ in degree of cursoriality: pikas (Ochotona princeps, non-cursorial), jackrabbits (Lepus californicus, highly cursorial), and rabbits (Sylvilagus bachmani, level of cursoriality intermediate between pikas and jackrabbits). We evaluated two hypotheses: cursoriality should be associated with (i) lower limb joint mechanical advantage (i.e. high 'displacement advantage', permitting more cursorial species to cycle their limbs more quickly) and (ii) longer, more gracile limb bones, particularly at the distal segments (as a means of decreasing rotational inertia). As predicted, highly cursorial jackrabbits are typically marked by the lowest mechanical advantage and the longest distal segments, non-cursorial pikas display the highest mechanical advantage and the shortest distal segments, and rabbits generally display intermediate values for these variables. Variation in long bone robusticity followed a proximodistal gradient. Whereas proximal limb bone robusticity declined with cursoriality, distal limb bone robusticity generally remained constant across the three species. The association between long, structurally gracile limb bones and decreased maximal bending strength suggests that the more cursorial lagomorphs compromise proximal limb bone integrity to improve locomotor economy. In contrast, the integrity of distal limb bones is maintained with increasing cursoriality, suggesting that the safety factor takes priority over locomotor economy in those regions of the postcranial skeleton that experience higher loading during locomotion. Overall, these findings support the hypothesis that cursoriality is associated with a common suite of morphological adaptations across a range of body sizes and radiations.
