Objective: To examine whether different exercise loading is associated with lumbar vertebral texture as assessed with Trabecular
Bone Score (TBS). Methods: Data from 88 Finnish female athletes and 19 habitually active women (reference group) were analyzed.
Participants’mean age was 24.3 years(range 17-40 years).Athletes were divided into five specific exercise loading groups according
to sport-specific training history: high-impact (triple jumpers and high jumpers), odd-impact (soccer players and squash players),
high-magnitude (power lifters), repetitive impact (endurance runners), and repetitive non-impact (swimmers). TBS-values were determined
from lumbar vertebral L1-L4 DXA images. Body weight and height, fat-%, lean mass, isometric maximal leg press force,
dynamic peak jumping force and lumbar BMD were also measured. Results: Endurance runners’mean TBS value differed significantly
from all other groups being about 6% lower than in the reference group. After controlling for body height, isometric leg press
force and fat-%, the variables found consistently explaining TBS, the observed between-group difference remained significant
(B=-0.072, p=0.020). After controlling for BMD, the difference persisted (B=-0.065, p=0.016). There were no other significant adjusted
between-group differences. Conclusion: Exercise loading history comprising several repeated moderate impactsis associated
with somewhat lower TBS, which may indicate specific lumbar microarchitecture in endurance runners.
