Strength training increases maximum motor neuron firing frequency in the elderly, eliminating age-related differences in this neural parameter.
Strength training improves how fast your nerves can signal your muscles, making your movements faster and more powerful, even in old age.
GoodSupportsHIGH confidence
Importantly, strength training can increase maximum MN firing frequency in the elderly and fully eliminate the age-related difference in maximum MN firing frequency observed in the untrained state

More from this paper
- Strength training effectively counteracts age-related sarcopenia and loss of neuromuscular function by inducing muscle hypertrophy and improving neural drive, even in individuals over 80 years old.Good
- Aging leads to a loss of spinal motor neurons and muscle fibers, resulting in sarcopenia and reduced functional capacity, which strength training can partially compensate for.Good

- 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
