Introduction[edit | edit source]
Closed kinetic chain exercise or closes chain exercise (CKC) is an exercise or movement where the distal aspect of the extremity is fixed to an object that is stationary.
In the physiotherapy, closed kinetic chain exercises are used before open kinetic chain exercises.
Here are some characteristics of CKC and the differences with open kinetic chain exercises: [1]
| Characterisctic |
Closed kinetic chain exercices |
Open kinetic chain exercises |
| Stress pattern |
Linear |
Rotary |
| Number of joint axes |
Multiple |
One primary |
| Nature of joint segments |
Both segments move simultaneously |
One stationary, other mobile |
| Number of moving joints |
Multiple joint movements |
Isolated joint motion |
| Planes of movement |
Multiple (triplanar) |
One (single) |
| Muscular involvement |
Significant co-contraction |
Isolation of muscle group, minimal muscular co-contraction |
| Movement pattern |
Significant functionally oriented |
Often non-functional |
Characteristic Closed kinetic chain exercises Open kinetic chain exercises

In general, fitness experts, physical therapists, and athletic trainers agree that closed chain exercises are better for you:
1. Closed chain exercises better mimic activities of daily living, which means they improve your “functional” fitness.
2. Closed chain exercises work many muscle groups at once. That’s great for the reasons above, but also because you can get more benefit in less time.
3. Closed chain exercises are safer for your joints—especially the knee joint, which is very vulnerable to stress and injury. The force involved in closed chain exercises like lunges and squats is compressive, meaning it actually stabilizes the joint and helps strengthen it. In contrast, open chain exercises, like knee extensions or hamstring curls produce shear force, which stresses the knee joint (and the ACL) and is more likely to result in injury. [2]
