= Hellin's law
{wiki=Hellin's_law}
Hellin's law, often referred to in the context of sports science and aging, describes a principle related to the decline in performance as athletes age. Specifically, it suggests that for most fundamental physical capacities, such as running speed, strength, and agility, there is a predictable decline associated with aging. This decline is typically around 1% per year after reaching peak performance, which is generally considered to occur in the late 20s to early 30s.
