Antimicrobial: This boat flooring is resistant to mold and mildew, an essential characteristic in a marine environment. UV stable: LWV is fade-resistant, so it keeps on looking gorgeous. Durable: The special vinyl backing is rated for heavy traffic, and the surface can easily withstand scrubbing with a deck brush.
The hamstring muscles actively bend (flex) the knee. They also act to straighten or (extend) the hip (as in the motion of moving the thigh backward). Surprisingly, these large muscles are not very active with normal walking or standing. However, they are extremely important in power activities such as running, jumping, and climbing.
The hamstrings cross and act upon two joints-the hip and the knee. Semitendinosus and semimembranosus extend the hip when the trunk is fixed; they also flex the knee and medially (inwardly) rotate the lower leg when the knee is bent.
