Aims:
To clarify the long-term effects of short-term exercise instructions by physical therapists in Japanese people with type 2 diabetes (T2D).
Methods:
This was a follow-up study of 2 years after randomized controlled study of short-term exercise instructions included 18 patients (5 in the non-intervention and 13 in the intervention groups). Motor skills, including 6 min walk test scores, and transtheoretical model was evaluated at baseline (week 0), the end of the study of the previous study (week 8), and 2 years after (2 years).
Results:
In the intervention group, changes in 6 min walk distance, which was significant at 8 weeks (from 445 (420-480) m to 490 (450-520) m, p = 0.01)), were maintained at 2 years (496 (420-540) m, p = 0.05), whereas in the non-intervention group, there were no changes in 6 min walk distance at 8 weeks (from 460 (458-493) m to 464 (460-485) m, p = 0.86) and 2 years (490 (480-506) m, p = 0.63). Furthermore, the changes in transtheoretical model, which was significant at 8 weeks (p = 0.008), were maintained at 2 years (p = 0.02), whereas in the non-intervention group, there were no changes in 6 min walk distance at 8 weeks and 2 years. On the other hand, the other markers were not significantly different between week 8 and 2 years compared to baseline in both groups.
Conclusions:
Short-term outpatient exercise instruction by physical therapists may lead to long-term improvement effect on walking ability in people with T2D.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
