The Benefit of Breaking Up Sedentary Time, According to Research

In the hustle and bustle of modern life, taking a break might often seem like a luxury. Yet, new research suggests that regular activity breaks may be just what you need to keep your health in check. This blog post will walk you through a recent study in the August 2023 volume of Medicine & Science in Sports & Exercise and its exciting findings, helping you grasp how simple changes in your daily routine can lead to significant health improvements.

The Benefit of Breaking Up Sedentary Time

Our fast-paced world has created an environment where long hours of sitting and minimal physical activity have become the norm. From office work to streaming your favorite series in the evenings, the opportunities for prolonged sedentary time are vast. This sedentary lifestyle has been linked to increased risks of type 2 diabetes, cardiovascular disease, and even certain cancers.

An emerging body of research is now highlighting the value of interrupting sedentary time with brief activity breaks. The benefits are clear: regular activity breaks help reduce postprandial glycemia (a risk factor for cardiometabolic diseases) and insulin levels, meaning your body manages sugar better after meals.

Let’s dive deeper into a recent study that investigated this topic in greater detail, and see how you can apply these insights to improve your health.

Understanding the Research

The study, conducted at the University of Otago, examined 30 participants of varying body mass index (BMI) categories. The participants were asked to do one of two things: sit continuously for 4 hours or sit with regular activity breaks that included 3 minutes of resistance exercises every half hour. The researchers measured plasma glucose, insulin, and triglyceride concentrations in response to meals provided at the beginning and after two hours.

The results? Compared to prolonged sitting, those who took regular activity breaks saw a significant decrease in plasma glucose and insulin levels. Notably, this effect was observed across all participants, regardless of their BMI. So, whether you’re underweight, overweight, or somewhere in between, interrupting your sitting time with regular activity could benefit your health.

What This Means for You

This research underscores the importance of incorporating regular activity into your daily routine, especially if you find yourself sitting for extended periods. It’s a simple strategy that can have powerful effects on your health.

Even though the study involved resistance exercises, this doesn’t mean you need to start lifting weights at your desk. The key takeaway is the act of moving, of getting your body active, rather than the specific type of exercise done.

Here are some simple ways you can put this research into practice:

  • Stand up and stretch every half an hour when working at your desk or watching TV.
  • Take a short walk around the room or up and down the stairs.
  • If you’re comfortable with it, perform some light resistance exercises such as squats or lunges.

By incorporating these actions into your routine, you can help your body better manage sugar levels and improve your overall metabolic health.

A Healthy Habit for Everyone

One of the most encouraging aspects of the study was the finding that the benefits of activity breaks were seen across all BMI categories. This means that everyone, regardless of weight, can reap the rewards of regular movement.

It’s worth noting that the magnitude of the effects varied between different weight groups. But, crucially, all groups did see benefits. So whether you’re trying to lose weight, maintain your weight, or even if weight is not a concern for you, this is a strategy you can use to enhance your health.

A Note on Evening Sedentary Time

In our busy lives, we often find ourselves winding down in the evening by binge-watching TV shows or movies. But the extended sedentary time in the evening could be harmful, particularly as we tend to consume a significant portion of our daily energy intake during this time.

By interrupting your evening relaxation with regular activity breaks, you’re helping your body manage your post-dinner blood sugar levels better. It’s a small change that can make a big difference.

Looking Ahead

This research is an exciting addition to our understanding of simple ways to improve health. However, as always, more research is needed, particularly in real-world, free-living environments. Future studies will ideally confirm these findings and identify the optimal frequency and duration of activity breaks.

Until then, don’t wait to start. Implement regular activity breaks into your day-to-day life. Stand, stretch, move, and make the most of your breaks. Your body will thank you.
