Quick Answer
Betaine Exercise Recovery Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Exercise-induced fatigue (EIF) refers to a reduced capacity to sustain a specified level or intensity of physical activity and is generally regarded as a physiological warning signal following excessive exercise rather than a pathological state.
Key Takeaways
- 01Exercise-induced fatigue (EIF) refers to a reduced capacity to sustain a specified level or intensity of physical activity and is generally regarded as a physiological warning signal following excessive exercise rather than a pathological state. [Yang Y (2026)]
- 02In this review, we synthesize evidence from nutritional interventions and acupuncture-based strategies and outline a conceptual mechanistic framework relevant to EIF management. [Yang Y (2026)]
- 03Acupuncture, electroacupuncture (EA), and transcutaneous electrical acupoint stimulation (TEAS) have been associated with regulation of autonomic function and hypothalamic-pituitary-adrenal axis activity, modulation of pain and affective circuits, and changes in skeletal muscle perfusion, mitochondrial function, and antioxidant and anti-inflammatory signaling. [Yang Y (2026)]
- 04It involves peripheral disturbances related to energy depletion, metabolite accumulation, oxidative stress, inflammation, and mitochondrial dysfunction, together with central changes involving neuroendocrine networks and the gut-brain axis. [Yang Y (2026)]

- No trial differences were found for I-FABP (interaction effect, p = 0.076), L: 13 CM ( p = 0.559), the neutrophil/lymphocyte ratio ( p = 0.171), serum cortisol ( p = 0.982), serum myoglobin ( p = 0.942), or serum creatine kinase ( p = 0.694). [Nieman DC (2025); evidence level 4]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
