Type 2 diabetes is a long-term condition that affects how the body controls blood sugar. When someone has this condition, their body cannot use insulin properly, which causes sugar to build up in the blood.
Over time, high blood sugar can damage the heart, kidneys, eyes, and nerves. Because of this, managing blood sugar is very important for people living with type 2 diabetes.
Doctors have long recommended exercise as a key way to control blood sugar. However, many people feel confused about what kind of exercise is best.
Some believe they must exercise at high intensity, while others think certain types of exercise, such as weight training or running, are more effective. A new study from the University of British Columbia Okanagan offers a simpler answer.
The research, published in Medicine & Science in Sports & Exercise, suggests that how long you exercise may be more important than how hard you exercise or what type of activity you choose. This finding could make exercise advice much easier to follow, especially for people who are newly diagnosed with type 2 diabetes.
The study was led by Dr. Jonathan Little and his team. They analyzed data from the MOTIVATE T2D trial, which followed 58 adults over 26 weeks. All participants were previously inactive and had recently been diagnosed with type 2 diabetes. Each person wore a fitness watch, which allowed researchers to track their exercise habits in detail.
The researchers looked at several factors, including how often people exercised, how intense their workouts were, and how long each session lasted. They also measured changes in blood sugar levels using a test called glycated hemoglobin, which shows average blood sugar over time.
The results showed a clear pattern. People who exercised for longer periods during each session had better improvements in blood sugar control. This was true regardless of whether the exercise was light or intense, or whether it involved cardio or strength training.
The study was divided into two parts. In the first 13 weeks, participants received strong coaching support. In the second half, support was reduced. The researchers found that building longer exercise sessions early on was especially important. These early habits seemed to help people maintain better results over time.
One important finding was that even small increases in exercise time made a difference. For example, increasing a workout from 30 minutes to 45 minutes was linked to a noticeable drop in blood sugar levels. While this change may seem small, it can have meaningful effects when repeated regularly.
This research is important because it simplifies exercise advice. Many people feel discouraged if they think they must exercise intensely to see results. This study shows that simply moving for a longer time may be enough to improve health.
The researchers also explained that longer sessions may be easier to maintain as a habit. People can choose activities they enjoy, such as walking, cycling, or swimming, and focus on spending more time doing them rather than pushing themselves too hard.
Study analysis: This study is valuable because it used real-time data from fitness trackers and followed participants over several months.
However, the sample size was relatively small, and the study was not originally designed to test this specific question. Even so, the findings are practical and helpful, suggesting that longer exercise sessions may be a simple and effective strategy for managing type 2 diabetes.
