“…Other studies have also suggested that it is younger men that have the highest prevalence of vertebral deformity,( 23–25 ) consistent with the effect of trauma. The data on walking are also consistent with a number of previous studies that bone density is better preserved in those who exercise more; these have shown a positive correlation between time spent walking and lumbar spine bone density in middle aged women( 26,27 ) and that when postmenopausal women exercise, BMD can increase in both unselected( 28 ) and osteoporotic women.

Physical activity is associated with an increased bone mass and a reduced risk of hip fracture. There are, however, no data from population samples of men and women concerning the effect of regular levels of physical activity on the risk of vertebral deformity. The aim of this study was to determine the relationship between regular physical activity and vertebral deformity in European men and women. A population survey method was used. Thirty-six centers from 19 European countries participated. Each center recruited a population sample of men and women aged 50 years and over. Those who took part received an interviewer-administered questionnaire and lateral thoracolumbar radiographs. Subjects were asked about two dimensions of physical activity: (1) the level of physical activity undertaken either at work or at home on a daily basis at three different age periods: 15-25 years, 25-50 years, and 50؉ years; and (2) the amount of time spent walking or cycling out of doors each day. Spinal radiographs were evaluated morphometrically and the presence of vertebral deformity was defined according to the McCloskey method. In total, 14,261 subjects, aged 50 -79 years, from 30 centers were studied, of whom 809 (12.0%) men and 884 (11.7%) women had one or more deformities. After adjusting for age, center, smoking, and body mass index, very heavy levels of activity in all three age groups were associated with an increased risk of vertebral deformity in men (odds ratios, age adjusted [OR], 1.5-1.7; with all 95% confidence intervals [CI] excluding unity). No increased risk was observed in women. Current walking or cycling more than 1 ⁄2 h/day was associated with a reduced risk of vertebral deformity in women (OR 0.8; 95% CI 0.7-1.0). We conclude that regular walking in middle-aged and elderly women is associated with a reduced risk of vertebral deformity. By contrast, heavy levels of physical activity in early and middle adult life are associated with an increased risk in men. These differences are of relevance in understanding the epidemiology of vertebral deformity and planning programs of prevention. (J Bone Miner Res 1997;12:813-819)

“…With exercise training, skeletal involution might be reversed without the untoward side effects seen in medical fitness and quality of life (Caplan et al, 1999;Zylstra et al, 1989). Some of related studies, especially those with cross-sectional design, have demonstrated a significant relationship between physical activity and bone mass.…”

“…The majority of the studies (e.g., Pocock et al, 1989;Kirk et al, 1989;Zylstra et al, 1989;see Marti, 1991) have been concerned with bone mineral and exercise in females, with other studies (e.g., Nilsson and Westlin, 1971;Watson, 1973;Dalen and Olsson, 1974) documenting changes in males. Most report a positive effect on bone mineral density of increased exercise, in some cases even with very modest levels of daily exercise.…”

The analysis of humeral asymmetry in Recent human skeletal samples and an extant tennis-player sample documents minimal asymmetry in bone length, little asymmetry in distal humeral articular breadth, but pronounced and variable asymmetry in mid- and distal diaphyseal cross-sectional geometric parameters. More specifically, skeletal samples of normal modern Euroamericans, prehistoric and early historic Amerindians, and prehistoric Japanese show moderate (ca. 5-14%) median asymmetry in diaphyseal cross-sectional areas and polar second moments of area, whereas the tennis-player sample, with pronounced unilateral physical activity, exhibits median asymmetries of 28-57% in the same parameters. A sample of Neandertals with nonpathological upper limbs exhibits similarly low articular asymmetry but pronounced diaphyseal asymmetries, averaging 24-57%. In addition, three Neandertals with actual or possible post-traumatic upper limb alterations have the same low articular asymmetry but extremely high diaphyseal asymmetries, averaging 112-215%. These data support those from experimental work on animals, exercise programs of humans, and human clinical contexts in establishing the high degree of diaphyseal plasticity possible for humans, past and present, under changing biomechanical loading conditions. This lends support to activity-related functional interpretations of changing human diaphyseal morphology and robusticity during the Pleistocene.
