Thanks to its non-impact closed kinetic chain
, with the Bionic Runner, you can eliminate the risk of injury from impact fatigue and joint over extension -- the two most common causes of joint, tendon and muscle-related strain injuries.
Like the baseball hitter, whose foot is fixed during the weight transfer onto the front foot during the bat swing, golfers also experience rotational velocities at the hip in a closed kinetic chain.
1993; Fleisig and Andrews, 1995), the fact that these are experienced in a closed kinetic chain, may produce sufficient torsion on the hip to predispose the joint to injury.
Over the past 10 years, isokinetics has become the exercise modality of choice for rehabilitating the lower extremity; however, a review of literature indicates that closed kinetic chain exercises have advantages over open kinetic chain exercises.
The relationship between open and closed kinetic chain strength of the lower limb and jumping performances.
There has been much written regarding the benefits of closed kinetic chain
exercise and joint loading exercises during rehabilitation (5).
Closed kinetic chain
exercise (squats, lunges, step-ups, stepdowns, split-squats, squat touches, push-ups, etc.
The Dynamic Flex[TM] is the only stretching device that works in a closed kinetic chain
creating the needed proprioceptive response between joint and muscle structures.
Analysis of the data suggests that open kinetic chain exercise (isokinetic training) did not lead to functional improvements on a closed kinetic chain
activity (Rapid Step Test).
