In dat eerste artikel bedoelen ze ook dat ermee, maar het is een discussie punt in de bodybuilding. en in het begin van het artikel (ik heb maar een klein deel hier neer gezet, staat het ook.
Although the precise cause is still unknown, the type of muscle contraction seems to be a key factor in the development of delayed onset muscle soreness. A recently developed theory states that delayed onset muscle soreness is caused by the breakdown of muscular fibres. This is particularly apparent in strength/resistance programs. The breakdown occurs due to stress, and allows the muscles to grow stronger and larger, as shown through
hypertrophy. Exercises that involve many
eccentric contractions, such as downhill running or slow "negatives" during
weight training, will result in the most severe DOMS. This has been shown to be the result of more muscle cell damage than is seen with typical
concentric contractions, in which a muscle successfully shortens during contraction against a load.
[2] Some research claims that delayed onset muscle soreness is not caused by the pain from damaged muscle cells, but from the reinforcement process.
[3] The muscle responds to training by reinforcing itself up to and above its previous strength by increasing the size of muscle fibers (
muscle hypertrophy). This reinforcement process causes the cells to swell in their
compartment and put pressure on nerves and arteries, producing pain.
