The "negative" phase of the repetition, the part with resistance as you return the weight from the end of the positive phase, back to the beginning. Eg, in the bicep curl, it is when you let the weight come back slowly to the beginning position.
isotonic contraction in which muscle lengthens while under tension.
This is a contraction in which the muscle lengthens and works with gravity.
A lengthening of the muscle during its contraction; controls speed of movement caused by another force.
Also called the "negative" movement, it's the lengthening of a muscle while under tension, such as lowering a barbell during a bench press or a barbell curl.
ECCENTRIC CONTRACTIONS Edema
A controlled lengthening of the muscle during its contraction; the resistance overcomes the muscular force and the muscle lengthens.
Muscle lengthens while maintaining tension.
A contraction where the muscle lengthens, such as when you lower a weight in your hand but resist the lowering. A dynamic action because of joint movement. This kind of contraction -- for example in your quadricep muscle when you run downhill -- tends to cause the most post-exercise muscle soreness.
the muscle lengthens while contracting against resistance.
