involves bending your
knees out to the side, making the parent feel as though they're pedaling like a frog.
Runners have a high rate of patellofemoral pain syndrome, in part because the motion of running
involves bending the
knee so many times.
This helps to develop power in the quadricep muscles (amongst others) as landing into a squat position
involves an eccentric contraction of the quads to decrease rapid
knee bending, before a concentric contraction to straighten the
knees and jump up.
When performing exercises on a vibration machine that
involves standing, always maintain a slight
bend in the
knees.
Correspondingly, the five phases that can be described between these positions are as follows: (1) the first pull happens between the ground and when the bar reaches
knee level and is initiated by
knee and hip extension; (2) the transition happens when the barbell is between
knee level and the power position and
involves a shift in the position of the body relative to the barbell, which
involves a brief period of
knee flexion and is therefore referred to as the double
knee bend (Enoka, 1979; 1988); (3) the second pull is the most powerful phase of the lift and occurs while the barbell is between the power position and the lifter is in triple extension; (4) turnover occurs as the lifter quickly drops down under the bar from the triple extension position to the catch position, in a deep front squat; (5) recovery into the standing position occurs as the lifter stands from the catch position to upright.
Performing a triple extension
involves moving from a position in which the hips,
knees and ankles are
bent, to a fully extended position in which all three joints are locked.
Since strength is specific, then: strength training exercises or exercise variations
involving moderately flexed peak
knee angles, very flexed hip and trunk angles, and some torso rotation or lateral
bend may be most valuable for improving COD ability.
This may imply that exercises
involving peak contractions when the
knee is
bent (like leg curls) are more effective at developing the hamstrings.
