Afonso et al. 2020, the effects of agility ladders on performance

International Journal of Sports Medicine systematic review of agility-ladder training. Despite the tool’s popularity, the evidence base is scarce and weak: only a handful of randomised trials, mostly short, with poorly described protocols and largely single-dimension outcomes. The authors conclude that claims agility ladders improve agility, speed or other physical skills are premature given the quantity and quality of evidence. Used here as the documented case that a popular training aid can lack the support its marketing implies.
