Extreme mountain ultra-marathons (approx. 166 km with significant elevation change) cause severe neuromuscular fatigue, including both central and peripheral components, with full recovery of maximal force capacity occurring within 9 to 16 days.
After completing an extreme mountain ultra-marathon (like the UTMB), expect significant muscle weakness and fatigue. Do not rush back into intense training. Most recovery happens within the first 9 days, but full neuromuscular function may take up to 16 days. Prioritize rest and light activity during this period.
Sixteen days after MUM, NMF had returned to initial values, with most of the recovery process occurring within 9 days of the race.
Why this rating
Well-controlled study with experienced subjects, clear metrics, and statistical significance, though limited to a specific extreme event.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
