What some people don't know is that it's the eccentric contraction that often causes muscle soreness because, as you lower the weight, your muscle is actually stretching at the same time they are contracting. This can result in muscle soreness, but it's a temporary soreness that should go away in a few days after exercise.

Muscle contraction - Wikipedia, the free encyclopedia
Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' impl...

1. It is known that a period of eccentric exercise provides protection against damage to muscle from subsequent eccentric exercise. ... 3. After a single period of eccentric exercise, angle-torque curves for muscles of both legs shifted in the direction of longer muscle lengths, suggestive of an increase in series compliance.

BACKGROUND: Exercise induced muscle damage (EIMD) from strenuous unaccustomed eccentric exercise is well documented. ... Recent studies have suggested that prior concentric training increases the susceptibility of muscle to EIMD following eccentric exercise. This has been attributed to a reduction of sarcomeres in series,

Figure 2: Plot demonstrating maximal tetanic force prior to and immediately following an exercise bout. While passive stretch causes negligible force decrement, isometric causes a moderate loss and eccentric causes a significant loss of force.

The Massachusetts researchers speculated that a strenuous bout of eccentric exercise 'teaches' the nervous system how to better control and distribute the forces that are acting on particular muscles.

Muscle damage from eccentric exercise: mechanism, mechanical signs, adaptation and clinical applications. ... In eccentric exercise the contracting muscle is forcibly lengthened; in concentric exercise it shortens. While concentric contractions initiate movements, eccentric contractions slow or stop them.

Whether you are an exercise fanatic or enjoy an occasional aerobics class or two, toning may be just what you need to get that shapely look you've been trying to achieve. ...

Perform the eccentric exercise slowly on days one and two, moderately on days three to five, and fast on days six and seven. Then increase the resistance (never more than five pounds for the cuff muscles). Three sets of repetition.
