Before and after a follow-up period of two-years, six male master cyclists (mean age was 59 years at the start of the study, cycle training; 5-6 hrs/wk) had dual-energy X-ray absorptiometry measured body composition (i.e., areal bone mineral density [aBMD] and appendicular lean soft tissue mass [aLM]) taken. aBMD at the femoral neck and lumber spine were similar between the two measurements, but aLM (p=0.056) tended to be higher at the 2-year follow-up. There were no significant (p>0.05) associations between changes in aLM and aBMD at femoral neck or lumber spine. Male master cyclists who exercise with a mild training volume (5-6 hrs/wk) maintained aBMD at the lumber spine and femoral neck. Furthermore, aLM tended to increase over the 2-year period. Further research is necessary to determine the training volume threshold needed to maintain aBMD in master cyclists.
