Abstract

SUMMARY Anabolic resistance and impaired myocellular quality contribute to age-related sarcopenia, which exacerbates with obesity. Diet-induced muscle mass loss is attenuated by resistance or aerobic plus resistance exercise compared to aerobic exercise in obese elderly. We assessed chronic effects of weight loss plus different exercise modalities on muscle protein synthesis response to feeding and myocellular quality. Obese older adults were randomized to weight-management program plus aerobic, resistance or combined aerobic and resistance exercise or to control. Participants underwent vastus lateralis biopsies at baseline and 6 months. Muscle protein synthesis rate increased more in resistance and combined than in control. Autophagy mediators’ expression decreased more in combined than in aerobic, which experienced a higher increase in inflammation and mitochondrial regulators’ expression. In obese elderly, combined aerobic and resistance exercise is superior to either mode independently for improving muscle protein synthesis and myocellular quality, thereby maintaining muscle mass during weight-loss therapy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Resistance training stimulates muscle protein synthesis during negative energy balance, promoting myogenesis, and is crucial for mitigating muscle mass loss associated with calorie restriction in adults with obesity.

    “RT stimulates muscle protein synthesis even during negative energy balance, promoting myogenesis, and is particularly crucial to mitigating the loss of muscle mass associated with CR in this population (18).”

    From The Benefits of Exercise Training in Combination With Weight Loss Therapies (2025) · cites this paper as [18]

    The Results section ('MPS rate in response to feeding improved most in COMB and REX groups'; page unavailable) reports increased meal-stimulated muscle protein synthesis during calorie-restriction-induced weight loss and says resistance exercise is particularly important for preserving lean mass in obese older adults. The Results section on myogenesis regulators reports that MEF2A expression was preserved with resistance or combined exercise, not that resistance training promoted myogenesis itself. The study also did not include a weight-loss-only group, limiting what it can establish about exercise versus calorie restriction alone. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Progressive resistance training during calorie restriction reduces the loss of lean mass.

    “When performed alongside CR, progressive resistance training (RT) attenuates this loss of lean mass and bone mass, while the addition of aerobic training (AT) further improves cardiorespiratory fitness.”
  • Exercise training reduces frailty in older adults by suppressing muscle inflammation and promoting anabolism, thereby increasing muscle protein synthesis rate.

    “Exercise training reduces frailty in older adults by suppressing muscle inflammation and promoting anabolism, thereby increasing muscle protein synthesis rate [148,336,337].”
  • Colleluori et al. showed that 6-month multicomponent training among obese older adults was more effective than aerobic or PRT alone for improving muscle protein synthesis and myocellular quality, even though mitochondrial biogenesis increased the most in the aerobic exercise group.

    “In a well-designed RCT, Colleluori et al. [148,336,337] showed that 6-month multicomponent training among obese older adults was more effective than aerobic or PRT alone for improving muscle protein synthesis and myocellular quality, even though mitochondrial biogenesis increased the most in the aerobic exercise group.”

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.
