Leg Raise - Force - Joints

Joints

Extending the knee joint (often called a straight leg raise]) increases the demands of leverage on both hip and spine flexors. It also reduces the contribution of the rectus femoris muscle via over-active insufficiency, creating more work for the non-quadriceps hip flexors.

The generic term "leg raise" usually indicates a bended knee, though the term "knee raise" is used to distinguish it from the category which includes both variations.

Famous quotes containing the word joints:

    Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.
    Walter Benjamin (1892–1940)

    To round that shell’s elaborate whorl,
    Adorning every secret track
    With the delicate mother-of-pearl,
    Made the joints of Heaven crack....
    William Butler Yeats (1865–1939)

    Farmers in overalls and wide-brimmed straw hats lounge about the store on hot summer days, when the most common sound is the thump-thump-thump of a hound’s leg on the floor as he scratches contentedly. Oldtime hunters say that fleas are a hound’s salvation: his constant twisting and clawing in pursuit of the tormentors keeps his joints supple.
