Eso es porque pueden ser enormes: una sola fibra muscular del sartorio puede tener 23 pulgadas de largo. La realidad dicta que pocos expertos saben por qu se produce este fenmeno en el organismo. Con el paso del tiempo, este fenmeno vino a llamarse memoria muscular. De hecho, pueden tener cientos de núcleos en una sola célula. Cuando la masa muscular se pierde, recuperarla es ms sencillo si hay una base previa de entrenamientos. Reversal of fibre cross-sectional area with detraining, and only modest improvement with retraining, suggests that much of the retention in strength with detraining and reacquisition of lost strength with retraining reflects neural adaptation. La memoria muscular funciona mediante células musculares las cuales son muy inusuales ya que pueden tener más de un núcleo por célula. The results indicate that elderly men lose some muscle strength following short-term detraining, but that only a brief period of retraining suffices to regain maximal strength. After 8 weeks of retraining, muscle strength returned to trained values, but without a significant change in fibre morphology. However, type I and II fibre cross-sectional area reverted to pretraining values. Of initial strength gains, only 29.9 +/- 5.2% was lost with detraining. Increased strength was accompanied by hypertrophy (P < 0.05) of type I (17.4 +/- 4.1%) and II (25.8 +/- 12.4%) muscle fibres. Muscle strength increased during initial training by 40.4 +/- 5.5% (mean +/- SEM), ranging from 26.0 +/- 5.0 to 83.9 +/- 15.6%, depending on muscle group. Needle biopsies of vastus lateralis muscle were obtained from seven men. Dynamic muscle strength was assessed by the 1-RM method every 2 weeks for 44 weeks. The resistance programme included three sets of eight repetitions at 75% of one-repetition maximum (1-RM), three times per week, for 10 upper and lower body exercises. During the detraining and retraining phase, subjects did not receive rhGH. It does not store any personal data.To investigate the effects of cessation and subsequent resumption of training on muscle strength in elderly men, 11 men (aged 65-77 years), just completing a 24-week randomized controlled trial of recombinant human growth hormone (rhGH) and resistance exercise (rhGH, n = 6 placebo, n = 5), detrained for 12 weeks and subsequently retrained for 8 weeks. No entanto, estes resultados ainda têm que ser confirmados por estudos em seres humanos.

O fenómeno da memória muscular pode ser explicado em grande parte pelo fato dos músculos manterem o mesmo número de núcleos musculares durante a perda de massa muscular ou falta de treino. Ao aderir a uma nova prática de exercícios, dependendo da atividade e frequência dela, o nosso cérebro cria um percurso, como se estivesse mapeando essas. Porém, ele se refere a capacidade das células dos músculos, em conjunto com o nosso cérebro, de guardar certos aspectos.
