People often walk a lot but don’t see any changes in weight or blood pressure. If this sounds like you, there might be a simple solution popularized in Japan.
This method is called interval walking training (IWT). Instead of maintaining a steady pace, you alternate between brisk walking and slower recovery periods. This technique engages the body more effectively and improves fitness.
Kristian Karstoft, a cardiometabolic researcher at the University of Copenhagen, has studied IWT for over ten years. He argues that most walkers stick to a comfortable speed, which might not be enough for significant health benefits. By changing your pace—alternating between faster walking and a relaxed pace—you enhance your body’s oxygen use. This can lead to lower blood pressure and help muscles utilize more sugar for energy.
Even small changes in speed can significantly impact your health. For example, consistent interval walking has been shown to improve insulin sensitivity, helping to stabilize blood sugar levels—crucial for preventing diabetes.
How Does It Work?
Here’s how to start: Walk at about 70% of your maximum effort for three minutes, then switch to about 40% effort. Repeat this for about 30 minutes. Experts suggest doing this five times a week to meet the recommended 150 minutes of moderate exercise.
What’s great is that you don’t need fancy equipment. A simple timer on your phone can help you switch your pace easily.
Proven Results
In a study with older adults, interval walkers increased their fitness levels significantly more than those walking at a steady pace. Those who trained with IWT saw a 10% improvement in their aerobic capacity and a notable drop in blood pressure. They also gained strength in their knees, reducing the risk of falls.
Remarkably, 95% of participants kept up with their walking routine throughout the study, showing that consistency outshines intensity.
Additional Benefits
IWT has also been tested among individuals with type 2 diabetes. The results revealed that the interval walkers were able to reduce abdominal fat and stabilize blood sugar levels, even with similar calorie burns compared to steady walkers. This shows that how you walk matters more than just the distance you cover.
Keeping Motivated
Walking is typically a low-risk, aerobic activity that won’t spike your heart rate dangerously. Studies indicate that serious side effects are rare, even for individuals recovering from surgery. To stay motivated, consider walking with friends or tracking your progress. Using apps that monitor your steps and encourage friendly competition can boost your commitment.
Getting Started
Before starting, it’s wise to consult a healthcare professional if you have health concerns. Choose a flat path and aim to start with shorter intervals, gradually increasing your brisk walking time as your fitness improves.
Walking doesn’t have to be boring or overly gentle. Adjusting your pace can significantly influence your health markers. The Japanese interval walking method shows that a few quick bursts can lead to better health—without needing a full workout.
