Corrective exercise interventions to regain ankle mobility and hip/core stability seem to be an effective measure to correct knee valgus (Bell et al., 2013; Padua, & DiStefano, 2009).

In these instances, flexibility exercises for the calves and possibly joint mobilization for the ankle may be required to regain 15-20 of ankle dorsiflexion. 4. Although the knees are relatively straight and stay in a fixed position during the lift, do not lock them out or hyperextend them. Stand in a split-stance position with your feet hip-width apart and one foot in front of the other. This type of resistance usually comes in the form of external load such as barbells, dumbbells, or selectorized strength-training machines. SLDL and RDL are known for specifically targeting the gluteus musculature and hamstrings (9,10). During the eccentric phase, muscle tension is present, but at a lesser magnitude than the opposing forces as your muscles lengthen. Sports Biomechanics, 12(3), 302-313.Fernndez-De-Las-Peas, C., Cuadrado, M., & Pareja, J. Both exercises are initiated by lowering the bar through hip flexion, moving through a full range of motion (ROM), before ending back in the standing position. > Slowly begin to squat down by hinging at the hips and then flexing at the knees. The exercise can be relatively simple if properly taught and supervised. The toes should be pointed forward or slightly outward. Grip Width and Forearm Orientation Effects on Muscle Activity During the Lat Pull-Down.

Frontal Plane: An imaginary plane that bisects the body into front and back halves. Some research indicates restriction in ankle mobility may cause knee valgus (knock knees), which is often a recipe for patellofemoral pain or even ACL injury (Bell, Oates, Clark, & Padua, 2013; Dill, Begalle, Frank, Zinder, & Padua, 2014; Macrum, Bell, Boling, Lewek, & Padua, 2012).

Initiate the exercise by simultaneously extending the knees, hips, and back. It also is important to note that if chronic, excessive low back pain is being experienced, the SLDL may exasperate the problem because of the distance between the load and the body.

Its the version most people will refer to when they say theyre doing lunges.. Know how to determine which deadlift exercise variation is best for a particular individual. In the upward phase of a squat, the same muscles that lengthened in the downward phase are activated concentrically to provide force for upward momentum against the force of gravity. 1. 47(5), 525-36. doi: 10.4085/1062-6050-47.5.10Padua, D., & Distefano, L.

Eccentric Exercise Is Powerful but Can Be Painful For example, during the concentric phase of a pull-up, the exerciser applies a pulling force to the bar, and as a result the elbows flex versus the bar breaking away from its support. An individuals heels rising off the floor is a not a common movement compensation, but it does occur from time to time (Figure 4). Other articles in this journal by Clifton J. Holmes, M.S.
