“…Among these studies, a few use the strength training, trying to increase the BMD in individuals submitted to that type of physical activity (7,13,14,17) . In general, the same studies have shown positive results related to the BMD (8,15,(17)(18)(19)(20)(21)(22)(23) . Nevertheless, despite this possible benefic effect, quite large training volumes may cause a damage on the BMD, and it seems that such damage is closely related to the disturbance in the hormonal homeostasis of the organism (5,6,24) .…”

“…According to Brighton et al apud Menkes et al (18) , a possible justification for the increase in the BMD to the strength training is the bone piezoelectric effect. This is suggested by the presence of biochemical signals that seem to reflect an electric field possibly as consequence for the applied overload.…”

“…These mechanical actions generate differences in the bones' electrical power that actuates as an electrical field stimulating the cellular activity, and leading to the deposition of minerals at stressed spots (Lanyon, Hartman apud Menkes et al) (18) . Nevertheless, the osteogenic effect derived from the physical activity appears to demand a high training level that is characterized by a great volume and intensity.…”

“…On the other hand, Menkes et al (18) verified that the increase in the BMD is due to the stimulation on the bone turnover, rather than to an attenuation of the reabsorption that occurs into that tissue. Andreoli et al (15) complement this theory suggesting that at the cellular level, the remodeling process overload-induced is performed by the action of the osteocytes that actuate as mechanical receptors of the applied stress and to the releasing of a stimulating chemical factor for the proliferation of the osteoblasts at the stressed spot.…”

The purpose of this article is to make a review on different sportive modalities and the power training on the bone remodeling, and to discuss the possible relationship of the bone mineral density (BMD) to the muscular power and body composition. Several studies indicate that the high impact physical activity or physical activities demanding a high power production may have a benefic effect on the BMD due to the deformation that occurs in such tissue during the activity. Some authors have been assessing the effects of the physical training on some biochemical markers of the bone remodeling, since the variation on the concentrations of these markers might indicate a bone turnover or reabsorption state. Nevertheless, the inconsistency of the results found suggests that the analysis of the effects of the physical activity on the bone remodeling through these markers must be further investigated. There are many discrepancies as to the relationship of the BMD to the muscular power and body composition, mainly to determine what factors are most associated to the BMD. The determination of what type of physical activity is the ideal to increase the bone mass peak during the adolescence or even aiming to keep it later in the adult years is quite important in order to prevent and possibly treat the osteoporosis.

Tratamentos não farmacológicos na estimulação da osteogênese

A carga mecânica provoca microdeformações ósseas, que estimulam células osteoblásticas e, conseqüentemente, promovem adaptações nos ossos, muitas vezes relacionadas com uma menor reabsorção óssea e um aumento na formação óssea local. No entanto, o estímulo para formação óssea depende do número e freqüência das deformações aplicadas no osso. Concomitantemente aos estímulos ósseos providos pelas cargas mecânicas, é importante uma dieta rica em cálcio, a qual também beneficia o aumento da massa óssea. Entretanto, existem também outros métodos não farmacológicos, como o ultra-som pulsado de baixa intensidade, a estimulação elétrica e o laser, que já mostraram efeitos positivos na promoção da osteogênese. Assim, realizou-se um levantamento na literatura, no período de 1982 a 2001, sobre esses métodos não farmacológicos com o objetivo de avaliar tais métodos alternativos, que ajudam no aumento da massa óssea ou no estímulo à osteogênese.

The association between bone mass, body structure, and body composition was explored in 156 men, 40 years of AGE. Bone mineral density (total body, lumbar spine, left arm, and left leg) was obtained by dual-energy X-ray absorptiometry (DXA; Hologic QDR 4500A). Body structure was determined from a battery of anthropometric dimensions with a principal components analysis. Body composition was estimated with DXA. From the 24 anthropometric dimensions, three components were extracted and identified as muscle, fat, and skeletal length. Significant correlations between the muscle component and all BMD measurements (r = 0.28-0.44) were obtained. Except for BMD of the left arm, which correlated significantly, but negatively, with the fat component (r = -0.16), no significant relations were found between the fat component and BMD. There were significant correlations between lean mass, fat mass, and BMD measurements. The correlations were higher between lean mass and BMD (r = 0.22-0.44) than between fat mass and BMD (r = 0.08-0.24). The multiple regression analysis revealed that except for BMD of the left arm only lean mass or the muscle component, and not fat mass or the fat component, were independent predictors of BMD. It is concluded that the principal anthropometric determinant of BMD in middle-aged men is lean mass or muscle.
