Brief summary
For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning. This study builds on our earlier research which demonstrated significantly improved blood glucose levels from a strength training program for older adults with T2DM. The strength training program is to be administered nationally in a research to practice trial (Lift for Life); however, the original research found that those who did not complete the program as it was intended (ie, poor adherence) did not show significant improvements in blood glucose levels. Furthermore, maintenance of strength training exercises after completion of the program was poor and resulted in return of blood glucose levels back to pre-starting levels. In people without diabetes, we have collected pilot data that shows that the use of behavioural strategies based on behavioural theories whereby each person’s motivations and barriers are taken into consideration is more effective than the traditional one-treatment-fits-all approach. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. The study will provide information that will assist in the design, delivery and uptake of programs to improve treatment strategies in older adults with T2DM through the maintenance of healthier behaviours and lifestyles.
Interventions
All participants will complete two (2) one hour group (4-12 people) strength training sessions per week (the "Lift For Life" strength training program), supervised by a physical trainer, for 6 months. A third unsupervised session is encouraged after 2 months.

A third unsupervised session is encouraged after 2 months. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. This approach will draw on conceptual frameworks of the Social Cognitive Theory and the Transtheoretical Model of behaviour change by incorporating well-established behaviour modification strategies, including self-monitoring, goal-setting and incentives. Over the intervention period (8 months), participants assigned to the Enhanced L4L group will receive: an initial 30 minute interview; weekly self-monitoring; six instructional newsletters (both print-based and/or web-based); 8 telephone calls; and motivational prizes/rewards. Interviews and telephone calls will be conducted by a Psychology-qualified research assistant. Anthropometric measures including circumferences and functional testing will be conducted at baseline, 2, 4, 6 and 12 months. Strength training adherence (number of strength training sessions performed), Glycated haemoglobin (HbA1c), physical activity and 3 repeat maximum (3RM) strength test, diet, general health, and blood pressure will be assessed at baseline, 6 and 12 months.
