Abstract
This study was designed to investigate the relationship between bone mineral density
(BMD) and weekly training volume (TV) in recreational adult male cyclists. Methods: Eleven
male participants (n=11; 38.9 +/- 5.5 yrs) were tested in duplicate, 12 weeks apart, for BMD at
four sites: total body (TB), lumbar (L), hip (H), and distal radius (R). Participants were also
measured for weight, % body fat, and VO2max. TV, in hours, over the 12 weeks was also
recorded for each participant at their usual self-selected volume. Statistics: BMD values from
the first testing session were standardized using reference values for a healthy adult male
population aged 30 yrs. Pearson’s correlation coefficients were calculated for all second session
BMD measurements against TV, weight and age. One-way ANOVA was used to compare BMD
values between groups with TV > 10 hr/wk (moderate) and TV < 5 hr/wk (low). Significance
for all analyses was set at p < 0.05. Results: Mean scores were found for TV (7.65 +/- 3.24
hr/wk), VO2max (4411.5 +/- 522.0 ml), weight (80.1 +/- 15.4 kg), and % body fat (17.7 +/- 5.1
%). No significant correlations were found between any BMD measurement (TB, L, H, R) and
TV (r = 0.216, r = -0.079, r = -0.248, r = 0.342). No differences in BMD at any site were
observed between the low volume and moderate volume groups. Conclusion: The results
suggest that there is no significant relationship between training volume and bone mineral
density at the total body, lumbar spine, hip, and distal radius in adult male cyclists. In addition,
it was concluded that road cycling at low to moderate training volumes is not associated with a
deleterious effect on bone.
