One limitation of research that assesses the effectiveness of physical activity interventions for people with dementia is that most do not describe the intervention in sufficient detail to ascertain a theoretical basis or mechanism of action that determines the effective components. This paper aims to identify studies which evaluate the mechanisms of action of physical activity interventions for people with dementia, to further inform effective intervention development.

Papers were screened for evidence of evaluation of specific forms of physical activity, using pre-defined inclusion criteria. Analysis was conducted to ascertain if mechanisms of action were corroborated by data within and between studies.

The authors identified 26 studies with a measured mechanism of action; these related to the effects of physical activity on either neurological structure or endocrinal markers, including hormones. Physical activity had potential to reduce hippocampal atrophy, increase neural recruitment, activate the noradrenergic system and improve anti-inflammatory responses. While individual studies were hampered by small sample sizes, the body of evidence indicated that physical activity may have potential to delay cognitive decline.

Mechanisms of action in relation to dementia and physical activity are likely to be multifaceted, and physical activity may be protective against progression in the early stages of cognitive decline. Physical activity may be of greatest benefit if incorporated into on-going lifestyle, rather than engaged in for short periods, and combined with social interaction.

This paper is unique in its focus on the mechanisms of action of physical activity interventions for people with dementia.

This article updates a review submitted to the Department of Health (DH) in the light of the House of Commons Health Select Committee report on Elder Abuse. The review drew on recent research about elder abuse in the UK, including research published after the Select Committee's hearings, that made specific recommendations for areas of development in research and policy. The aim of this paper is to address specific questions posed by the Select Committee in light of developments up to mid 2005.

Of all the major, global professional sports where women have made inroads, striving toward equality in terms of status, earnings and media attention, tennis stands at the forefront. This chapter traces this historical development, outlining the sport's earliest socio-cultural features that afforded the inclusion of female players and charting the progress of notable women who thrust tennis into the limelight and turned themselves into commodities – the essence of professionalisation. Suzanne Lenglen blazed the trail by becoming, in 1926, the principal attraction in the sport's inaugural professional tour. Female players were encouraged to cast aside the shackles of restrained femininity and chart their own courses in a sport still dominated by men and played according to male standards. The rise of ‘Open Tennis’ in 1968 removed the playing restrictions and stigma of professionalism, but by opening up to the male-dominated corporate world, unsurprisingly it was the male players who initially competed for the lion's share of new money. Billie Jean King's efforts to galvanise her fellow female professionals to compete on a rogue tour sponsored by Virginia Slims left them ousted by the sport's main officials, but the tour's commercial success propelled them toward equality in terms of prize money and status. Still more or less a white, middle-class-dominated pursuit, the arrival of Venus and Serena Williams in the late 1990s turned tennis toward new markets, and the sport's significance for women remains apparent in the fact that its leading players are the most recognisable and well-paid of all professional female athletes.

This chapter reviews qualitative research on parenting children with disabilities published over the last 50 years to explore whether shifts in academic discourse and changes in professional training have affected research on parenting and/or the experiences of parents who are the subject of such research.

An extensive literature search was conducted, and 78 peer-reviewed, qualitative studies on the experience of parenting a child with a disability were included in the sample. Themes were extracted from the reviewed literature and compared across decades.

The findings of the present review suggest that some aspects of the parenting experience have changed very little. In particular, parents continue to experience negative reactions such as stress and anomie, especially early in their children’s lives, and socially imposed barriers such as unhelpful professionals, and a lack of needed services continue to create problems and inspire an entrepreneurial response. In addition, stigmatizing encounters with others continue to be a common occurrence. In contrast to earlier decades, studies conducted in more recent years have begun to use the social model of disability as an analytic frame and also increasingly report that parents are questioning and challenging the concept of “normal” itself.

Additional improvements are needed in professional education and services to reduce the negative reactions experienced by parents of children with disabilities.

The findings of this meta-analysis can serve as a guide to future research on parenting children with disabilities.
