“…The results indicate that stroke-induced disuse causes bone loss, leading to increased serum calcium levels, which in turn inhibit PTH secretion and vitamin D production. Studying bone markers also provides a dynamic assessment of bone turnover [44,[63][64]. A significant negative correlation was found between the level of NTx (urinary cross-linked N-telopeptides of type I collagen, a bone resorption marker) and degree of motor recovery and walking ability [64].…”

A significant negative correlation was found between the level of NTx (urinary cross-linked N-telopeptides of type I collagen, a bone resorption marker) and degree of motor recovery and walking ability [64]. Other studies have also found that individuals with stroke have lower levels of intact bone Gla protein (gamma-carboxyglutamate, a bone formation marker) [44,63,65] but higher levels of pyridinoline cross-linked carboxy-terminal telopeptide of type I collagen (ICTP, a bone resorption marker) when compared with nondisabled control subjects [63,65].…”

Abstract-Fractures occur frequently in people living with stroke and have high personal, social, and economic costs for these individuals, their families, and the community. Exercise to reduce the risk of fragility fractures is a relatively new application in stroke rehabilitation but is a promising treatment with the potential to reduce the incidence of falls as well as maintain or improve bone health. In this article, we outline fracture risk factors and provide an overview of exercise interventions aimed at reducing fracture risk poststroke. Although randomized controlled trials support the use of exercise to reduce fracture risk factors poststroke, the body of literature is small and further studies are required. Further, the optimal dose of exercise and the additive effects of pharmacology on fracture risk need to be determined. Given the many health benefits associated with exercise, it should be considered an important modality for the management of falls and maintenance of bone health following stroke.

“…Some papers 23 found a significant fall in bone mass, with four sessions per week. However, a five sessions per week program 24 led to a remarkable density increase, about 4%, compared to the initial level. Nevertheless, women around 45kg participated in this program, performing 15 repetition series, while in our study 30 repetitions per series were done, concentrated in two weekly sessions.…”

Introduction: Several studies have analyzed the relationship between physical activity and bone density. However, the prescription of exercise is not entirely clear as to the type, quantity and intensity. Objective: The objective of this study was to determine if there is a relationship between the amount of exercise and changes in bone mineral density. Methods: Fifty-two women, members of the Municipal Program of Physical Activity for Seniors, voluntarily underwent two ultrasonographies of the calcaneus within a 6-month interval. During this period, all physical activity was recorded. Afterwards, a lineal correlation study was carried out between the amount of exercise and bone changes, expressed as T-Score variation, first in total number of participants and then in groups. Considering the average body weight obtained for all women, two groups were created ("light" < 69 kg and "heavy" > 69 kg). Later, women who had participated in less than 72% of the targeted program were excluded from both groups, and the differences between the groups "light and trained" and "heavy and trained" were analyzed. To do so, the nonparametric Mann-Whitney U test was used. Results: A significant relationship of r= -0.59 was found between the total amount of exercise and the T-Score variation in the group of women above 69 kg. Significant differences were found between the "light and trained" group and the "heavy and trained" group with respect to the variation of T-Score. Conclusion: The effect of exercise on bone mineral density is determined, somehow, by body weight. This interaction is due, possibly, to mechanical demands difference.

“…Nevertheless, establishing comparisons is complicated, owing to the fact that bone loss rhythm is not the same in every anatomic zone (Mitchell & Yerges-Armstrong, 2011). In that sense, although prescription of physical exercise in order to increase bone density is not clear in older population, several papers prove the benefits of training (Ilona, Taina, Mirela, Eugenia, & Mihaela, 2010;Villareal et al, 2011;Kohrt et al, 1997;Iwamoto et al, 2001;Verschueren et al, 2004), either increasing bone status or diminishing the rhythm of loss.…”

Abstract:The objective of this study is to analyze the effectiveness of a physical activity program addressed to older people. 48 people were involved in the performance of calcaneus bone ultrasonography and anthropometry tests. Afterwards, over six months, all physical activity was registered. At the end of this period, ultrasonography and anthropometry tests were again performed. Quality of life was also measured. Collected data show great incidence of overweight and osteoporosis. However, the training program does not significantly reduce fat mass but it does not increase the muscle mass either. Furthermore, bone mass loss reached 2.2% (p=0.003). These results show the inefficiency of a training program with the usual features of physical activities offered to older people. If the results of our study are confirmed, this kind of programs would not be contributing to achieve a healthy aging process, at least from a physical point of view.
