[32] It reduces the quadriceps eccentric contraction, while it preserves the isometric and concentric quadriceps strength.
Greater values of both power and movement velocities (Tab.1-3) for the [ECC.sub.REG] tempo can be related to a more effective use of elastic energy generated during the eccentric contraction, and it's release during the CON phase of the movement (Clark et al., 2010; Cronin et al., 2001; Cronin and Henderson, 2004; Lindstedt et al., 2002; Newton et al.,1997).
A control group performed all exercises with two seconds of concentric muscle contraction and four seconds of eccentric contraction -- that is, two seconds of the kind of contraction from lifting and four seconds of the kind of contraction from lowering.
The first mechanism of injury occurs following a forceful eccentric contraction at a high speed, during the late swing phase of the running gait cycle.
Inexperienced vigorous exercise, including eccentric contraction (ECC), induces muscle damage, edema, reduction of tension, limitation of the range of motion, and muscle pain.
(2,4,7) IT injuries are often seen with sudden, aggressive lengthening of the hamstring muscles, whereas injuries to the ASIS and AIIS are the result of abrupt eccentric contraction of hip extensor muscles while the knee is flexed.
Concentric contraction causes shortening while eccentric contraction causes the lengthening of muscle as it exerts tension against the external load to move the bony lever.
The results can be used to indirectly confirm the type of motion (concentric contraction or eccentric contraction) of the muscle groups (extensors or flexors) around joints.
First, the eccentric contraction force of the ISP tendon peaks in the deceleration phase of overhead motion.
In the present study there was no reduction in Sp[O.sub.2] probably because eccentric contraction was performed in only one exercise movement and one muscle group (ECC knee extension of quadriceps muscle).
* More muscle endurance--The use of slow, continuous motion in Pilates forces the body to use concentric and eccentric contraction. The constant workload on the muscle improves muscle endurance.
It's a training method based on the understanding that a concentric muscular contraction is much stronger if it immediately follows and eccentric contraction of the same muscle.
