OBJECTIVE
 Compare measures of training, performance, body comp, and areal bone mineral density (aBMD) between age-matched recreational and competitively trained male road cyclists
DESIGN
(1) Male cyclists (N = 28) aged 21-54 years riding more than 3 hours per week
(2) Men who train at high (≥8 h/wk) and moderate volumes (3-8 h/wk)
RESULTS
(1) Trained cyclists had higher power to weight and training volume than recreational cyclists
(2) Trained cyclists had lower right and left hip aBMD
(3) Z-scores identified lumbar (L1-L4) aBMD as osteopenic (-2.5 < Z-score < -1.0) in trained cyclists (-1.39 ± 1.09)
(4) Lumbar scans identified 12 trained and 4 recreational cyclists as osteopenic and 3 trained cyclists as osteoporotic
CONCLUSIONS
(1) Areal bone mineral density is lower in trained male road cyclists compared with recreational, specifically at the hips
(2) Lumbar aBMD is low in both trained and recreational cyclists
(3) Research is needed to determine the chronic effects of cycling on aBMD and interventions that improve aBMD in this population
CLINICAL RELEVANCE
– This study suggests road cycling may compromise aBMD and potentially increase the likelihood of low-trauma fractures
