# Alpha memo: skeletal muscle signal

**Research question:** How far does the Receipt 1 signal transfer across the setting tested by Receipt 2?

**One-sentence alpha:** Aging-dependent effects of repetitive loading exercise and antioxidant supplementation on oxidative stress in skeletal muscle made us expect antioxidant would help recovery or performance; Dietary Antioxidants-contained Foods Promote Skeletal Muscle Adaptation And Reduce Fatigue Induced By Resistance Training forces the update that the same intervention may be bounded by training modality or adaptation endpoint.

**Receipt 1:** Dietary Antioxidants-contained Foods Promote Skeletal Muscle Adaptation And Reduce Fatigue Induced By Resistance Training | 2018 | 10.1249/01.mss.0000538371.32684.87

**Receipt 2:** Aging-dependent effects of repetitive loading exercise and antioxidant supplementation on oxidative stress in skeletal muscle | 2010 | 10.33915/etd.3093

**Synthesis:** Receipt 1 reports Dietary Antioxidants-contained Foods Promote Skeletal Muscle Adaptation And Reduce Fatigue Induced By Resistance Training; excerpt: RESULTS: Lean body mass was significantly increased in both groups (p < 0.05). in a human study. Receipt 2 reports Aging-dependent effects of repetitive loading exercise and antioxidant supplementation on oxidative stress in skeletal muscle; excerpt: Aging is associated with a reduced ability to buffer oxidants along with an increase in oxidant production, resulting in chronic oxidative stress. in an animal model. The comparison is bounded to skeletal muscle, and should not be read as advice, settled science, or a broad class claim.
**Bounded contrast:** Receipt 1 axes: men, strength, resistance, exercise, training, adaptation. Receipt 2 axes: mice, aged, resistance, exercise, training, adaptation, function.
**Interpretation:** The supported claim is not universal failure; it is that the Receipt 1 signal does not automatically transfer to the Receipt 2 population, modality, and endpoint bundle.

**Why this is surprising:** The same named anchor is not enough. The useful signal is the boundary between the two receipt settings and endpoints, not a literature-average claim about skeletal muscle.

**Limitations:** This pair does not isolate whether species, population, dose, duration, modality, or endpoint class explains the split.

**Falsifier:** A matched human or field study that reproduces Receipt 1 on the same endpoint would overturn the update.

**Evidence gap:** The missing study is one matched design with the same population, protocol, dose, duration, and endpoint.

**Next test:** Run the same skeletal muscle comparison in one matched design before treating the signal as general.
