Walking is a simple, cost-free form of exercise that benefits physical, social, and mental health in many ways. Several clinical trials have shown that walking regularly is associated with a lower risk for cardiovascular events and all-cause mortality, and having a higher daily step count is linked to a decreased risk for premature death.

In recent years, the link between walking speed and the risk for multiple health problems has sparked keen interest. Data suggest that a faster walking pace may have a greater physiological response and may be associated with more favorable health advantages than a slow walking pace. A previous meta-analysis of eight cohort studies suggested that individuals in the fastest walking-pace category (median = 5.6 km/h) had a 44% lower risk for stroke than those in the slowest walking-pace category (median = 1.6 km/h). The risk for the former decreased by 13% for every 1 km/h increment in baseline walking pace.

Type 2 diabetes (T2D) is one of the most common metabolic diseases in the world. People with this type of diabetes have an increased risk for microvascular and macrovascular complications and a shorter life expectancy. Approximately 537 million adults are estimated to be living with diabetes worldwide, and this number is expected to reach 783 million by 2045.
