Home-Based Circuit Training in Overweight/Obese Older Adult Patients With Knee Osteoarthritis and Type 2 Diabetes

Participants in the exercise group performed HBCT three times per week on non-consecutive days for 12 weeks. The first session was conducted at USM Hospital and participants were instructed how to perform the prescribed exercises in a correct form. In each session, participants performed seven exercises (two aerobic- and five resistance-based) in a circuit fashion, using bodyweight movements and adjustable dumbbells for varied weights, activating all the major muscle groups. In weeks 1-6, participants executed 15 repetitions for 2 rounds with 1 min passive rest between exercises and rounds. In weeks 7-12, participants executed 30 repetitions for 4 rounds with the same rest as prescribed in weeks 1-6. Each round lasted 10-15 min and the total session duration was 20-60 min, aiming to help participants adapt gradually to increasing training volume.
