A new exercise protocol known as “Japanese walking,” or interval walking training (IWT), has emerged as an effective method for improving cardiometabolic health, particularly among older adults. Developed by Japanese researchers, IWT emphasizes alternating between intervals of fast and slow walking, making it accessible for individuals of various fitness levels.
Research indicates that participants engaging in IWT may experience significant health benefits, such as improved blood pressure, body mass index (BMI), blood glucose levels, and overall physical fitness. In a study involving over 200 adults with an average age of 63, those following IWT demonstrated superior outcomes compared to traditional continuous walking methods. The IWT protocol typically consists of three minutes of brisk walking (at about 70% of peak aerobic capacity) followed by three minutes of slower walking (around 40% of peak capacity), ideally performed for a minimum of 30 minutes, five days a week.
An analysis of adherence to the IWT protocol revealed a 95% compliance rate, suggesting that the program is not only effective but also sustainable for participants. Additionally, a recent review confirmed the established health benefits of IWT for both middle-aged and older adults, particularly noting its efficacy in improving physical fitness and glycemic control for individuals with type 2 diabetes.
For those interested in starting an IWT regimen, experts suggest beginning with manageable goals and gradually increasing intensity. It is important to consult a physician before initiating any new exercise routine. Practitioners are encouraged to monitor their comfort levels, wear appropriate footwear, and utilize tools like fitness trackers to enhance their walking experience.
