The aim of this study was to describe the behaviour and perceptions of women in aerobic or exercise to music classes. In particular, the study examined the meaning women attach to this activity choice and the interaction of aerobics participation with cultural pressures and beliefs such as that of the ‘ideal female bodyshape’. A naturalistic method of study was chosen in order to gain a comprehensive view of the subjective experience of aerobics participation. Approximately fifty female health club members were observed over a three month period in order to identify and describe patterns of involvement, behaviour and perception and the factors affecting them. Six groups of women were identified. These were ‘Naturals’, ‘Compulsive’, ‘Functional Feminist’. Several factors were observed as potentially contributing to the patterns observed. These included attitude toward perceived cultural ideals and pressures of female expectation and shape, perceptions of aerobics and exercise, pre-occupation with slenderness and bodyshape, self-image and body image. The relationship between these factors was found to be dynamic and reciprocal, with participation possibly intensifying or alternately reducing bodyshape concern. Aerobics was seen to have a multifaceted yet very individual and important appeal to the women observed.

Background:
Methods and design:
This is a stepped wedge cluster randomised controlled trial design. A total of 180 participants will be recruited from 15 community satellite hemodialysis clinics in a large metropolitan Australian city. Each clinic will represent a cluster unit. The stepped wedge design will consist of three groups each containing five randomly allocated cluster units, allocated to either 12, 24 or 36 weeks of the intervention. The intervention will consist of an accredited exercise physiologist-coordinated program consisting of six lower body resistance exercises using resistance elastic bands and tubing. The resistance exercises will include leg abduction, plantar flexion, dorsi flexion, straight-leg/bent-knee raise, knee extension and knee flexion. The resistance training will incorporate the principle of progressive overload and completed in a seated position during the first hour of hemodialysis treatment. The primary outcome measure is objective physical function measured by the 30-second sit to stand test. Secondary outcome measures include the 8-foot timed-up-and-go test, the four square step test, quality of life, cost-utility analysis, uptake and involvement in community activity, self-reported falls, fall's confidence, medication use, blood pressure and morbidity (hospital admissions).
Discussion:
The results of this study are expected to determine the efficacy of an accredited exercise physiologist supervised resistance training on the physical function of people receiving hemodialysis and the cost-utility of exercise physiologists in hemodialysis centres. This may contribute to intradialytic exercise as standard therapy using an exercise physiologist workforce model.
