“…The regular practice of physical activity improves bone mass acquisition, as demonstrated by observational (3) and interventional studies in young children (4 -6). The beneficial effects of exercise on areal bone mineral density (aBMD), bone geometry, and, consequently, bone strength have been confirmed by cross-sectional studies in young athletes (7)(8)(9). Nevertheless, the favorable effect seems to be exercise-dependent and only physical activity that generates high mechanical strain induces additional bone mass gain during growth (5,6).…”

Context:Cross-sectional studies have demonstrated that physical activity can improve bone mass acquisition. However, this design is not adequate to describe the specific kinetics of bone mass gain during pubertal development. Objective:To compare the kinetics of bone mass acquisition in female adolescent athletes of sports that impose different mechanical loads and untrained controls throughout puberty.Study Participants: A total of 72 girls with ages ranging from 10.8 to 18.0 years were recruited: 24 rhythmic gymnasts (RG, impact activity group), 24 swimmers (SW, no-impact activity), and 24 age-matched controls (CON). Main Outcome Measures:Areal bone mineral density (aBMD) was determined using dual-energy x-ray absorptiometry and bone turnover markers were analyzed. All the investigations were performed at baseline and after 1 year.Results: At baseline and after 1 year of follow-up, RG presented significantly greater aBMD adjusted for age, fat-free soft tissue, and fat mass compared with CON and SW, only at the femoral region. When aBMD variation throughout the pubertal period was modeled for each group from individual values, the aBMD at the femoral region was significantly higher in RG compared with the other 2 groups from 12.5 to 14 years, and this difference lasted up to 18 years. Moreover, the mean annual aBMD gain tended to be higher in RG compared with SW and CON only at the femoral region and this gain lasted longer in RG. Bone remodeling markers decreased similarly with age in the 3 groups. Conclusions:This study, which was based on linear mixed models for longitudinal data, demonstrated that the osteogenic effect of gymnastics is characterized by greater bone mass gain localized at mechanically loaded bone (ie, the proximal femur) principally around the menarcheal period. Moreover, the bone mass gain lasts longer in gymnasts, which may be explained by the delay in sexual maturation. (J Clin Endocrinol Metab 98: 2844 -2853, 2013)

Introduction: Rhythmic gymnastics requires a high level of physical quality; therefore, good performance depends on muscular strength and endurance, motor coordination and postural balance. Objective: Develop a comparative analysis of postural balance in rhythmic gymnasts. Methods: 10 rhythmic female gymnasts were evaluated on a force platform on one-foot and balance functional tests (Side Hop Test and Figure of Eight Hop Test). The anteroposterior and mediolateral of the center of pressure (COP) parameters were used for the functional tests, while for the functional tests, the performance time-seconds was analyzed. Results: Significant difference (p = 0.01) was found between lower limbs in the mean frequency parameter in the mediolateral direction, in which the non-dominant lower limb presented higher postural stability than the dominant one. For functional tests, there was no significant difference between limbs. Conclusion: The difference found in the control of balance of mediolateral direction may be related with different muscular actions of the hip region, which is present during the sport practice for stabilization, trunk maintenance and maneuvers performance with the lower limbs. These results indicate the need of a balance program and pelvic stabilization for the analyzed athletes in order to maintain muscular symmetry of the limbs for high sports performance.

“…Complimentary to this, regular physical activity, resulting in increased loading, increases both the mineral content and the density of bone as well as reducing the rate of demineralization (DiGiovanna 1994;Wheadon and Heaney 1993). Furthermore, athletes have been shown to have BMD values greater than nonathletes (Eisman et al 1991;Maimoun et al 2011;Markou et al 2010), and an even more dramatic example, tennis players have higher BMD in their dominant compared to their nondominant arm (Calbet et al 1998;Haapasalo et al 1998). Specifically regarding these mechanicalloading factors, the skeleton likely responds to mechanical stress such as increased body weight with a stimulation of osteoblast activity (Wardlaw 1996;Turner and Pavalko 1998;Mullender et al 2004).…”

Age-related bone loss is well established in humans and is known to occur in nonhuman primates. There is little information, however, on the effect of dietary interventions, such as caloric restriction (CR), on age-related bone loss. This study examined the effects of long-term, moderate CR on skeletal parameters in rhesus monkeys. Thirty adult male rhesus monkeys were subjected to either a restricted (R, n0 15) or control (C, n015) diet for 20 years and examined throughout for body composition and biochemical markers of bone turnover. Total body, spine, and radius bone mass and density were assessed by dualenergy X-ray absorptiometry. Assessment of biochemical markers of bone turnover included circulating serum levels of osteocalcin, carboxyterminal telopeptide of type I collagen, cross-linked aminoterminal telopeptide of type I collagen, parathyroid hormone, and 25(OH)vitamin D. Overall, we found that bone mass and density declined over time with generally higher levels in C compared to R animals. Circulating serum markers of bone turnover were not different between C and R with nonsignficant diet-by-time interactions. We believe the lower bone mass in R animals reflects the smaller body size and not pathological osteopenia.

In peripubertal girls, artistic gymnastics improves areal bone mineral density and femoral bone geometry without affecting serum OPG/RANKL levels

Abstract: GYM is associated not only with an increase in aBMD but also an improvement in bone geometry associated with an increase in bone remodelling. These adaptations seem to be independent of the OPG/RANKL system.
