Community center-based resistance training for the maintenance of glycemic control in adults with type 2 diabetes

OBJECTIVE--The purpose of this study Was to determine whether beneficial effects on glycemic control of an initial laboratory-supervised resistance training program could be sustained through a community center-based maintenance program.

RESEARCH DESIGN AND METHODS--We studied 57 overweight (BMI [greater than or equal to] 27 kg/[m.sup.2]) sedentary men and women aged 40-80 years with established (>6 months) type 2 diabetes. Initially, all participants attended a twice-weekly 2-month supervised resistance training program conducted in the exercise laboratory. Thereafter, participants undertook a resistance training maintenance program (2 times/week) for 12 months and were randomly assigned to carry this out either in a community fitness and recreation center (center) or in their domestic environment (home). Glycemic control ([HbA.sub.1c] [A1C]) was assessed at 0, 2, and 14 months.

RESULTS--Pooling data from the two groups for the 2-month supervised resistance training program showed that compared with baseline, mean A1C fell by -0.4% [95% CI -0.6 to -0.2]. Within-group comparisons showed that A1C remained lower than baseline values at 14 months in the center group (-0.4% [-0.7 to -0.03]) but not in the home group (-0.1% [-0.4 to 0.3]). However, no between-group differences were observed at each time point. Changes in A1C during the maintenance period were positively associated with exercise adherence in the center group only.

CONCLUSIONS--Center-based but not home-based resistance training was associated with the maintenance of modestly improved glycemic control from baseline, which was proportional to program adherence. Our findings emphasize the need to develop and test behavioral methods to promote healthy lifestyles including increased physical activity in adults with type 2 diabetes.

Community Care in Australia

Access and equity are guiding principles for community care in Australia. Community care in Australia is universally provided through Australia's Medicare system, which assures all people access to needed services. The largest community care system, the Home and Community Care Program (HACC), serves frail older and disabled people. The HACC program is undergoing steady reform to provide more seamless transitions of care for people from home care to residential care whether permanent or for respite purposes. Community health services provide a wide range of center-based and outreach services that any person may access and that are provided on the basis of need. Nevertheless, pressures for greater privatization of services cause tensions, and access is jeopardized further by shortages, particularly in rural areas, of aged care nurses, allied health personnel, and medical practitioners.

Squatting at the digital campfire: researching the open source software community

This paper describes an internet-mediated netnography of the open source software (OSS) community. A brief history of OSS is presented, along with a discussion of the defining characteristics of the phenomenon. A theoretical rationale for the method is then offered and several unique features detailed. The evolution of the methodology in practice is described and salient lessons highlighted. In addition to gathering a large volume of rich data as intended, early phases of the implementation of this method produced a number of unanticipated but significant findings. The paper concludes by summarising the key methodological considerations for conducting a phenomenology of a true online community
