Resistance exercise is the primary mechanical stimulus to prevent the decline in Type 2 muscle fiber cross-sectional area in older adults.
Engage in regular resistance training to maintain the size and function of your fast-twitch muscle fibers. This mechanical stimulus is crucial for keeping your muscles strong and functional as you age.
GoodSupportsHIGH confidence
Resistance exercise is found to be very effective in preventing the decline in the CSA of type 2 fibres, mainly by stimulating the mTOR pathway (Moro et al., 2020; Kosek et al., 2006; Verdijk et al., 2009).
Why this rating
Supported by multiple citations of resistance training studies in older adults.
