* One study<ref name="WILLSON"/> showed that as people become tired, their cadence goes up, and with the higher cadence goes lower impact forces. Although a shorter stride/faster cadence results in less landing force, a longer stride length/lower cadence is associated with less of the impact force reaching the head<ref name="Mercer-2003"/>.
* The impact forces at a longer stride length are mostly absorbed by the knee<ref name="Derrick-1998"/>.
* Adding extra weight to the ankles of recreational runners did not change their Cadence or stride length at various speeds<ref name="Cavanagh-1989"/>. The study showed that Cadence remained nearly constant while stride length increased with speed, with or without weights of up to 1.1 kg/2.4 pounds.
* A review of the scientific studies showed consistently that an increased [[Cadence]] reduces shock at the hip, knee, and ankle, vertical oscillation, and ground contact time<ref name="SchubertKempf2013"/>.
* Barefoot running tends to have a higher cadence than shod<ref name="Divert-2005"/>.
* There is relatively little evidence concerning the height or leg length of athletes and their cadence.
** A study of 37 male senior elite triathletes indicated that height did not change Cadence, but taller athletes were faster and had longer stride lengths <ref name="Brisswalter-1996"/>.
[[File:Cadence and Impact.jpg|none|thumb|500px|This chart<ref name="Mercer-2003"/> shows the impact forces for three different cadences at the same speed. The thick line shows the Preferred Strike Frequency (PSF) and Preferred Strike Length (PSL), which was a cadence of 84. The thin line has the runners with a 10% slower cadence of 76 and shows increased impact. The dotted line shows 10% faster cadence of 93 and a reduced impact force.]]
