Spinal cord injury (SCI) derives in loss of bone mineral content (BMC) and bone mineral density (BMD). However, physical activity is an important determinant in bone mass acquisition, which is partially mediated through the lean mass (LM). The aim was to examine the effect of cardiorespiratory fitness (CRF) on BMD and BMC arms of adult males with SCI and able-bodied controls using the arm LM as a mediator variable. Thirty able-bodied men and thirty men with SCI participated. BMC and BMD were analysed by DXA, and indirect calorimetry was used to calculate VO2peak during a progressive arm-cranking test. When groups were divided by the amount of LM, the subgroup with highest LM had significantly higher arm BMC compared to the lowest LM subgroup (p ≤ 0.05) in both SCI and able-bodied groups. Moreover, same differences were found when confidence intervals were analysed. Only in the SCI group, arm LM mediated the relationship between bone mass and CRF at 30.9%, as indicated by the Sobel test (z = 2.17 and z = 2.04 for BMC and BMD, respectively). In conclusion, LM mediates the indirect association between CRF and bone health, specifically in the arms. This finding highlights the importance of having an adequate CRF for the maintenance of good bone health in SCI men. 相似文献

Distance education courses are offered in a wide variety of formats. A range of media is available, and mechanisms for and levels of study and administrative support vary widely between courses. When new courses are established there is a wealth of experience to draw upon but little, if any, guidance on how to choose between the plethora of potential course formats. This article suggests that synthesising guidelines from evaluations of a selection of courses can help in drawing conclusions as to how courses are best formatted for given situations. As a case study, seven Hong Kong distance education courses with a variety of features were evaluated. Conclusions were synthesized—about the provision of tutorials, group activities, inter-student contact, telephone counselling and the use of video and television broadcasting—which could not have been reached from either evaluating one course alone or by examining existing literature. 相似文献

In attachment research, there has been a growing interest in how adults conceptualize their relationships with their own parents as well as in the transmission of attachment status from parent to child and the variables that influence that transmission. The primary goal of the present study was to examine the transmission of attachment from deaf mother to child. Adult Attachment Interviews were collected on 32 deaf women and Strange Situation Procedure data were obtained from their children. While the distribution of deaf mother attachment classifications was similar to that found with hearing samples, the concordance between mother and child in terms of attachment status was lower than in hearing samples. Having a deaf parent did not affect a deaf adult's attachment status. Post hoc analyses suggested a trend towards a dismissing stance in attachment relationships. Results are discussed in terms of variables affecting attachment status as well as the transmission of attachment. 相似文献
