Abstract The purpose of this study was to explore the upper limit of total bone mineral content (BMC, kg) and bone mineral density (BMD, g/cm2) in humans by estimating body composition of Sumo wrestlers. A total of 54 male college Sumo wrestlers were recruited for the study and assigned to 2 groups according to body weight (middleweight, 85-115 kg, n = 23 and heavyweight, >115 kg, n = 31). BMC, BMD, fat mass and lean soft tissue mass (LSTM) were measured using dual-energy X-ray absorptiometry (DXA) for the total and appendicular regions. Heavyweight Sumo wrestlers had significantly greater body weight, fat mass, and LSTM compared to middleweight Sumo wrestlers. Mean total BMC was significantly larger in heavyweight than middleweight Sumo wrestlers, respectively (The highest value was 4.16 kg.). Total BMD was significantly higher in heavyweight compared to middleweight Sumo wrestlers (The highest value was 1.59 g/cm2.), and was significantly correlated with body weight, but not with fat mass and LSTM. Based on the present and previous studies, the upper limit of total BMC and BMD in humans with 150 kg bodyweight might be around 5.0 kg and 1.60 g/cm2.

Cranial Cruciate Ligament

Following cranial cruciate ligament transection and extracapsular stabilization, dual-energy X-ray absorptiometry was used to analyze bone mineral content and lean tissue mass in the surgical and nonsurgical legs (n=14) at 0, 2, 4, and 8 weeks, and to evaluate bone mineral content and bone mineral density (BMD) of the proximal, mid-, and distal tibia of both the surgical and nonsurgical legs (n=15) at 0, 5, and 10 weeks. There was significant loss of bone mineral content and lean tissue in the surgical leg compared to the nonsurgical leg. Significant loss in bone mineral content and BMD was detected in the tibia of the surgical leg and was most pronounced in the metaphyseal region.

A previous study using single photon absorptiometry has reported low bone mineral density of the radius in infants of diabetic mothers. The aim of this study was to assess by dual x-ray absorptiometry the whole body bone mineral content (WbBMC) and the body composition of 40 infants of diabetic mothers at birth (mean gestational age ± sd, 37.5 ± 1.3 weeks; mean birth weight ± sd, 3815 ± 641 g). WbBMC was not correlated with gestational age, but was well correlated with birth weight (r = 0.73; P = 0.0001) and also with fat mass (r = 0.87; P = 0.0001) and lean mass (r = 0.42; P = 0.008). The z-scores ± sd adjusted for weight for WbBMC and fat mass were significantly increased (1.3 ± 0.9 and 2.6 ± 1.3, respectively (P < 0.0001), but were not significantly influenced either by in utero growth or by the type of the diabetes mellitus of the mother. Bone mineralization and fat mass studied by whole body dual x-ray absorptiometry are increased at birth in these infants compared with reference curves.

The Relationship

The relationship between muscle strength and bone mineral density illustrates the positive effect of mechanical loading on bone. But local and systemic factors may affect both muscle and bone tissues. This study investigated the effects of long-term tennis playing on the relationship between lean tissue mass and bone mineral content in the forearms, taking the body dimensions into account. Fifty-two tennis players (age 24.2 ± 5.8 yrs, 16.2 ± 6.1 yrs of practice) were recruited. Lean tissue mass (LTM), bone area, bone mineral content (BMC), and bone mineral density were measured at the forearms from a DXA whole-body scan. Grip strength was assessed with a dynamometer. A marked side-to-side difference (p <  0.0001) was found in favor of the dominant forearm in all parameters. Bone area and BMC correlated with grip strength on both sides (r = 0.81-0.84, p <  0.0001). The correlations were still significant after adjusting for whole-body BMC, body height, or forearm length. This result reinforced the putative role of the muscles in the mechanical loading on bones. In addition, forearm BMC adjusted to LTM or grip strength was higher on the dominant side, suggesting that tennis playing exerts a direct effect on bone.

SummaryThe objective was to determine signalment-related differences in bone mineral content (BMC) and bone mineral density (BMD) in dogs. Unilateral appendicular bones were harvested from 62 canine cadavers. Middiaphyseal regions of interest (ROIs) were scanned using a Hologic® DXA device Braincon, Vienna, Austria). BMC and BMD were calculated within this region. Middle-aged dogs (3 . 10 years) revealed the highest BMC and BMD levels. Mean BMC and BMD were higher in males compared to females. Furthermore, bodyweight of the male dogs was significantly higher compared to the females (P<0.0001). Body weight and bone length were significantly associated with BMC and BMD (P.0.023) in all bones but the radius. These data suggest that BMC and BMD appear to be highest in male large-breed dogs with a body weight greater than 30 kg. These results may help determine risk factors in fracture development and healing.
