The research
Research on patellar tendinopathy keeps pointing the same way: supports can make activity more comfortable, and progressive loading is what changes the tendon. That is why our range covers both.
45
In six volleyball players with patellar tendinopathy, a single session of five 45-second heavy isometric quad holds reduced tendon pain immediately, and the effect lasted at least 45 minutes.
25
A pilot study found that eccentric squats on a 25 degree decline board reduced pain in athletes with chronic patellar tendinopathy, while the same squats on flat ground did less.
6
In a randomized trial, heavy slow resistance training and decline squat training both improved patellar tendinopathy at six months, while the benefit of steroid injections faded.
These studies looked at exercise programs, not our products. Our products are supports and tools, not treatments. If pain is severe, follows an injury or lasts more than a few weeks, see a doctor or physical therapist.
