As you know there are two kinds of kinetic chain exercises. Open kinetic chain (OKC) exercises, are movements where the hand and the foot are usually free/not fixed, these type of exercises usually better at isolating muscles e.g. knee extension. In a closed kinetic chain (CKC) exercise, the distal segments are usually fixed or stationary, and tend to be more functional movements e.g. squat.

So where am I heading with this? Well reading a yet to be published paper by Erin Feser last week and she had an interesting spin on the benefits of wearable resistance as a kinetic chain exercise. When wearing a pair of shorts or calf sleeves during walking, running and/or sprinting, you’re getting a two for one overload in the same movement, that is you're getting OKC overload during the swing or airborne phase of the step cycle and a CKC overload during the stance or ground contact phase. I think that is novel. Thoughts? Do you know of any other training methods/tools that provide a double whammy OKC/CKC overload?
