Skeletal Muscle Autophagy and Protein Breakdown Following Resistance Exercise are Similar in Younger and Older Adults
Open accessAbstract
BACKGROUND: The loss of skeletal muscle mass and strength during aging, sarcopenia, increases the risk for falls and dependency. Resistance exercise (RE) training is effective at improving muscle mass and strength in older adults; however, aging is associated with reduced training-induced hypertrophy. Recent research has illustrated an impaired muscle protein synthetic response following an acute bout of RE in older adults but much less is known regarding the effect of acute RE on muscle protein breakdown (MPB). We hypothesize that the ubiquitin proteasome system and the autophagosomal-lysosomal system may regulate the overall rate of MPB during postexercise recovery. METHODS: Muscle biopsies of the vastus lateralis were sampled from 16 older (age = 70±2 years) and 16 younger (age = 27±2 years) participants at baseline and at 3, 6, and 24 hours following an acute bout of RE. In conjunction with stable isotopic techniques to measure MPB, we utilized immunoblotting and RT-PCR to examine protein and mRNA expression for key signaling molecules in both the ubiquitin proteasome system and the autophagosomal-lysosomal system. RESULTS: MuRF1 mRNA expression increased, whereas GABARAP mRNA decreased after RE in both younger and older adults (p < .05). The LC3B-II/LC3B-I protein ratio decreased in both groups after RE (p < .05), but MPB was not different 24 hour post-RE in either group (p > .05). CONCLUSIONS: Aging does not influence skeletal MPB, autophagy, or the ubiquitin proteasome system following an acute bout of RE. Therefore, targeting the muscle protein synthesis response to exercise may hold more promise in the prevention of sarcopenia.

Studies including an exercise intervention have reported both similar and distinct quality control responses in young and older adults.
“Studies that included an exercise intervention have also been performed and reported both similar and distinct quality control responses in young and older adults (25,35,36).”

Recent studies investigating whether mitochondrial quality control is influenced by aging have produced inconclusive results.
“Recent studies have investigated whether mitochondrial quality control is influenced by aging, but the results are not conclusive and remain to be elucidated (1,2,25,35,36).”
From Chronological Age Does not Influence<i>Ex-vivo</i>Mitochondrial Respiration and Quality Control in Skeletal Muscle (2016) · cites this paper as [35]
The Discussion says more research is needed on age-related skeletal muscle autophagy, but it does not address whether studies of mitochondrial quality control in aging have produced inconclusive results. Searches for “mitochondrial quality control,” “mitochondria,” and “mitophagy” found no passage in our copy that settles that claim. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
