Bone density and neuromuscular function in older competitive athletes depend on running distance
Summary Individuals who are involved in explosive sport
types, such as 100-m sprints and long jump, have greater
bone density, leg muscle size, jumping height and grip
strength than individuals involved in long-distance running.
Introduction The purpose of this study is to examine the relationship
between different types of physical activity with bone,
lean mass and neuromuscular performance in older individuals.
Methods We examined short- (n050), middle- (n019) and
long-distance (n0109) athletes at the 15th European Masters
Championships in PoznaĹ, Poland. Dual X-ray absorptiometry
was used to measure areal bone mineral density (aBMD) and
lean tissue mass. Maximal countermovement jump, multiple
one-leg hopping and maximal grip force tests were performed.
Results Short-distance athletes showed significantly higher
aBMD at the legs, hip, lumbar spine and trunk compared to
long-distance athletes (pâ¤0.0012). Countermovement jump
performance, hop force, grip force, leg lean mass and arm
lean mass were greater in short-distance athletes (pâ¤0.027). A
similar pattern was seen in middle-distance athletes who typically
showed higher aBMD and better neuromuscular performance
than long-distance athletes, but lower in magnitude
than short-distance athletes. In all athletes, aBMD was the
same or higher than the expected age-adjusted population
mean at the lumbar spine, hip and whole body. This effect
was greater in the short- and middle-distance athletes.
Conclusions The stepwise relation between short-,middle- and
long-distance athletes on bone suggests that the higher-impact
loading protocols in short-distance disciplines are more effective
in promoting aBMD. The regional effect on bone, with the
differences between the groups being most marked at loadbearing
regions (legs, hip, spine and trunk) rather than nonload-
bearing regions, is further evidence in support of the idea
that bone adaptation to exercise is dependent upon the local
loading environment, rather than as part of a systemic effect

Relationship of bone mineral density with disease activity and functional ability in patients with ankylosing spondylitis: a cross-sectional study
In ankylosing spondylitis, inflammatory activity probably plays a key role in the pathophysiology of bone loss. The aim of the study was to investigate the relationship of bone mineral density (BMD) at the lumbar spine and hip region with some measures of disease activity and functional ability in patients with ankylosing spondylitis. In 80 patients with established ankylosing spondylitis, disease activity and functional ability were determined by C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI). Spinal pain and patient global health were assessed using horizontal visual analog scale. BMD was measured by dual-energy X-ray absorptiometry. There was a significant negative correlation of bone density T scores with acute-phase reactants (i.e., patients with lower T scores had higher level of CRP and ESR). That relationship was reflected more reliably at proximal femur sites than at the lumbar spine. There were also significant differences in ESR, BASDAI, BASFI, spinal pain and global health between three groups of patients according to WHO classification of osteoporosis (normal, osteopenic and osteoporotic). Significantly, more patients with osteopenia at the lumbar spine had lower BASDAI index than those with normal BMD (P = 0.030). Our results indicate an association of low BMD with high disease activity in patients with AS. Femoral BMD seems to be more associated with disease activity and functional ability than lumbar spine BMD
