Prevent Muscle Loss and Improve Mitochondrial Health | Nicolas Verhoeven

About this video

Dr. Lyon speaks with PhD candidate Nick Verhoeven about mitochondrial health, sarcopenia, and muscle function in aging. Verhoeven explains how muscle denervation, mitochondrial dysfunction, and loss of neuromuscular connectivity contribute to age-related muscle loss and decreased power output. They discuss exercise modalities, autophagy, fiber type changes, and evidence for supplements like creatine and the glycine/NAC combination (GlyNAC) in supporting muscle and brain health.

Key takeaways

• Verhoeven argues that age-related sarcopenia involves not just muscle loss, but also decreased strength and power output, often driven by denervation (the disconnection between nerve cells and muscle cells) and mitochondrial dysfunction.
• According to the guest, exercise—both aerobic and resistance training—is the most powerful intervention for mitochondrial health, increasing mitochondrial number, quality, and fat oxidation capacity.
• Verhoeven suggests that creatine supplementation (typically 3–5 grams) shows particularly strong evidence in older individuals for supporting both muscle and brain health, including memory and neuroprotection.
