Background & Hypothesis

The study aimed to evaluate and demonstrate that short duration of moderate-intensity exercise can effect acute changes in blood glucose (BG).

Methods

Participants with diabetes attended a small group 3-hour workshop comprising of didactic teachings with hands-on activities. Workshops were conducted by a multi-disciplinary team between July 2018 and March 2021. In one of the activities, participants measured their capillary BG followed by 20-minute moderate-intensity resistance exercise before checking BG immediately post-exercise. Participants also completed a post-workshop feedback questionnaire.

Results

A total of 117 people with Type 2 diabetes attended the workshops. There were 49.6% male, mean age was 56.3 ± 12.9 years, mean diabetes duration was 8.1 ± 8.4 years, mean BMI was 27.4 ± 4.7 kg/m2. There was significant reduction in BG (mmol/L) after 20 minutes of exercise (9.4 ± 3.9 to 8.5 ± 3.7, p<0.001). Change in BG was not significantly correlated with weight, age, or diabetes duration. A higher baseline BG (>7mmol/L) resulted  in greater BG reduction post-exercise (p<0.001). Of the 46.1% participants who completed the feedback questionnaire, all (100%) agreed or strongly agreed that the workshop was relevant, easy to understand, they acquired new knowledge, and they would practice what was learnt. There were no differences in BG change between those who completed questionnaire and those who did not.

Discussion & Conclusion

Short duration moderate-intensity exercise in an education programme demonstrated significant reduction in BG. Its durability and long-term impact in changing behaviour and improving glycaemic control needs further follow up.
