    • Aging, Skeletal Muscle, and Epigenetics 

      Stewart, Claire E.; Sharples, Adam (Peer reviewed; Journal article, 2022)
      We are living in an aging society. In 2019, 1 billion individuals were already aged over 60. The number of people in this demographic is predicted to reach 1.4 billion by 2030 and 2.1 billion by 2050 (WHO). In the USA, ...

    • Effects of acute and chronic strength training on skeletal muscle autophagy in frail elderly men and women 

      Aas, Sigve Nyvik; Tømmerbakke, Daniel; Godager, Sindre; Nordseth, Martin; Armani, Andrea; Sandri, Marco; Benestad, Haakon Breien; Raastad, Truls (Peer reviewed; Journal article, 2020)
      Aging is associated with alterations in skeletal muscle autophagy, potentially affecting both muscle mass and quality in a negative manner. Strength training with protein supplementation has been reported to improve both ...

    • Effects of High-Intensity Interval Training and Isoinertial Training on Leg Extensors Muscle Function, Structure, and Intermuscular Adipose Tissue in Older Adults 

      Bruseghini, Paolo; Capelli, Carlo; Calabria, Elisa; Rossi, Andrea; Tam, Enrico (Peer reviewed; Journal article, 2019)
      We compared the effects of aerobic high-intensity training (HIT) and isoinertial resistance training (IRT) on the strength, mass, architecture, intermuscular adipose tissue (IMAT) quality, and neuromuscular activation of ...

    • Exercise is associated with younger methylome and transcriptome profiles in human skeletal muscle 

      Voisin, Sarah; Seale, Kirsten; Jacques, Macsue; Landen, Shanie; Coffey, Vernon G.; Walsh, Colum; Davison, Gareth; McBride, Catherine; Irwin, Rachelle; Hansson, Ola; Asplund, Olof; Harvey, Nicholas R.; Haupt, Larisa M.; Griffiths, Lyn R.; Ashton, Kevin J.; Thompson, Jamie-Lee M.; Doering, Thomas M.; Lindholm, Maléne E.; Sharples, Adam P.; Eynon, Nir (Peer reviewed; Journal article, 2023)
