"Discover the benefits of the rising health fad, 'Japanese walking': a workout you should consider"
In the world of fitness, a new method has emerged that promises significant health benefits: Japanese Walking, also known as Interval Walking Training (IWT). Originating from Japan, this approach to exercise has been linked to improved mental and cardiovascular health, and it can be effective for managing back pain [1][3][5].
IWT is a form of interval training, which involves alternating between bursts of intense activity and more gentle movement or rest. In this case, fast and slow walking [6]. The aim is to improve health outcomes more efficiently than continuous walking at a moderate pace [3].
Key benefits of Japanese walking versus traditional walking include:
Cardiovascular Health and Metabolic Improvements: - Interval walking leads to stronger heart adaptations and improved circulation due to alternating walking intensities, raising cardiovascular fitness more efficiently [3]. - It has been shown to reduce blood pressure significantly [4][5], improve healthy HDL cholesterol, reduce triglycerides, and lower abdominal visceral fat [1][5]. - It lowers risk factors for lifestyle-related diseases such as type 2 diabetes and heart disease by improving blood pressure, BMI, blood glucose, and cholesterol levels [5].
Muscle Strength and Physical Fitness: - Studies demonstrate increased leg, thigh, and hamstring muscle strength (e.g., 13% and 17% increases respectively) after interval walking programs, surpassing gains from moderate walking [1][5]. - Older adults engaging in interval walking showed better endurance and flexibility compared to those sticking to steady walking [3].
Mental Health and Cognitive Function: - Interval walking improves cognitive function, depression symptoms, sleep quality, and overall emotional well-being [1][3][5]. - Its varied pace makes it less monotonous and more motivating than traditional walking, potentially aiding adherence [1][3].
Back Pain and Musculoskeletal Health: - Although direct research on Japanese walking for back pain is limited, related walking variations (such as backward walking) have been found to strengthen lower back muscles and improve flexibility, which can reduce back pain [2]. The muscle-strengthening effects of interval walking likely also contribute to back health.
Benefits for Older Adults: - Because walking is low-impact, interval walking is suitable for older individuals or those new to exercise, offering substantial fitness benefits without excessive joint strain [1][3]. - Improved endurance, strength, cardiovascular function, and mental health translate to better overall function and quality of life for older adults [3].
The method, first introduced two decades ago by Hiroshi Nose, an exercise physiologist at Shinshu University Graduate School of Medicine in Japan, suggests starting low and going slow when adding interval walking to an exercise routine [7]. It's recommended to begin with shorter fast intervals (e.g., 1 minute) and gradually increase duration [7].
Regular recovery breaks during interval walking can result in spending more time exercising at a high intensity compared to continuous walking at that intensity [8]. If interval walking is the main form of exercise, it's recommended to complement it with at least two days a week of strength training, along with balance and mobility training [9].
The researchers also suggest engaging your arms, bending them at the elbows and swinging them vigorously with each step, which will help you maintain proper form during longer strides [10].
In recent years, Japanese walking has gained popularity, with a growing body of evidence from Drs Nose and Masuki and other researchers reinforcing these findings and suggesting that interval walking may have even more benefits [1][3][5]. In fact, it has been a trend on TikTok this summer [11].

Science has extensively researched the health benefits of fitness-and-exercise methods, with interval walking (IWT) being one of the recent innovations. Notably, this approach has been linked to health-and-wellness improvements such as improved cardiovascular health and metabolic improvements [1][3][5]. This science-backed exercise strategy, originating from Japan, can be effective in managing back pain [1][3][5].
