You don't need to lift heavy weights to strengthen and tone your core muscles, according to a personal trainer who shares ...

This study compares concentric and eccentric contraction training. How does each affect isotonic muscle strength?

In this event, one would expect the rate of either isometric or isotonic contraction to be slowed up in the presence of heavy water (D2O).

Discussion Compared to isotonic contractions, a single strength training bout of isometric contractions reduced patellar tendon pain immediately and for at least 45 min post intervention and increased ...

An isotonic contraction is one that includes a concentric (shortening) and eccentric (lengthening) portion, like when you bend your knees and lower into the lunge, and then extend your legs again.

Can you exercise without moving a muscle? In fact, you can. Check out these examples of isometric exercise and learn what the benefits may be.

Parametric two-way repeated-measures analysis of variance (ANOVA) was used to compare groups, types of contractions and evaluation times regarding isotonic strength, PPT, TNF-α and cortisol and ...
