The Acute Satellite Cell Response and Skeletal Muscle Hypertrophy following Resistance Training

Abstract: The extent of skeletal muscle hypertrophy in response to resistance training is highly variable in humans. The main objective of this study was to explain the nature of this variability. More specifically, we focused on the myogenic stem cell population, the satellite cell (SC) as a potential mediator of hypertrophy. Twenty-three males (aged 18–35 yrs) participated in 16 wk of progressive, whole body resistance training, resulting in changes of 7.9±1.6% (range of −1.9–24.7%) and 21.0±4.0% (range of −7.0 to 51.… Show more

“…In this regard, the results of some studies suggest that RT could result in body mass (and specifically fat mass) loss and increase insulin sensitivity in active tissues, such as skeletal muscles. The addition of RT to AT may prove crucial in that RT has an improved ability to stimulate greater insulin sensitivity in active tissues and to increase the amount of such active tissue via muscle hypertrophy (40), especially following hypertrophy RT (41).…”

“…As células satélites são células mononucleares, quiescentes e caracterizadas por estarem localizadas entre o sarcolema e a lamina basal apresentando a capacidade de proliferação e diferenciação estando intimamente ligadas ao processo de hipertrofia muscular (MUIR, KANJI e ALLBROOK, 1965;HAWKE e GARRY, 2001;PETRELLA et al, 2008;BELLAMY et al, 2014;BLAAUW e REGGIANI, 2014). Tanto a idade como o nível de treinamento parecem ser capazes de modular as respostas dos genes e das proteínas envolvidas no processo de ativação das células satélites, bem como a quantidade das mesmas que são fundidas às células musculares esqueléticas PETRELLA et al, 2006;RAUE et al, 2006;VERDIJK et al, 2009).…”

“…Alguns trabalhos mostram que as fibras do tipo II são mais recrutadas durante o TFR quando comparadas às fibras do tipo I (MORITANI et al, 1992;TAKARADA et al, 2000b;SUGA et al, 2012) das mesmas, conduz a um balanço proteico positivo que resulta nessa hipertrofia. As células satélites e sua capacidade de proliferação e diferenciação em novos mionucleos parecem estar intimamente ligadas ao processo de regeneração e hipertrofia muscular (PETRELLA et al, 2006;PETRELLA et al, 2008;BELLAMY et al, 2014;BLAAUW e REGGIANI, 2014).…”
