This era marked the beginning of integrating technology into personal fitness monitoring, setting the stage for the sophisticated wearables we use today.
The Manpo-Kei: Pioneering Electronic Step Counting
In 1965, Dr. Yoshiro Hatano, a Japanese professor at Kyushu University of Health and Welfare, introduced the Manpo-kei, which translates to “10,000 steps meter.” Dr. Hatano’s research aimed to combat obesity by encouraging individuals to walk 10,000 steps daily, a regimen he found effective in maintaining a healthy balance between caloric intake and expenditure. The Manpo-kei became a cultural phenomenon in Japan and laid the foundation for the step-counting features prevalent in modern fitness trackers.
Advancements in Wearable Technology
The late 20th century witnessed further innovations in wearable fitness technology. Companies began developing devices that not only counted steps but also monitored other physical activities and vital signs. These advancements were propelled by the miniaturization of electronic components and the increasing interest in personal health monitoring. Patents during this period reflect a growing emphasis on integrating multiple sensors into compact, user-friendly devices.
One notable example is the development of wearable systems designed for monitoring strength training.
