Monitoring athletes is fundamental to exploring the relationship between load and risk of injury. Traditionally, load monitoring in sport was limited to single metrics of external load such as running mileage, but this has recently advanced to quantification of multiple internal (eg, heart rate and rating of perceived exertion) and external loading variables (eg, running speed, watts produced, on-field impacts and number of accelerations). A 2016 consensus statement by the International Olympic Committee on load in sport and risk of injury highlighted that sport-specific guidelines for load management were lacking; empirical data must develop beyond a few select sports and populations.1 Forthcoming research must incorporate load measures relevant and specific to sports of interest.

Jumping is associated with injury

Popular multidirectional sports such as volleyball or basketball have significant jumping demands. Although we know the distinct movement patterns that can cause injuries during landing (ie, dynamic lower extremity valgus and stiff-legged landings),2 jumping and landing loads have been vastly understudied and we do not know when these movement strategies might transition from occasional aberrant mechanics to injurious …
