Navigating Exercise Intolerance After Concussion with Dr. Mike T Nelson | E22

Dr. Mike Nelson shares his expertise on exercise intolerance after concussion, explaining that neurological limitations, not metabolic fatigue, are the primary barrier to resuming physical activity. The key difference is that your nervous system acts as a brake on performance, preventing your body from accessing its existing physical capabilities.

• Exercise testing should be individualized, focusing on symptoms rather than rigid heart rate parameters
• Different exercise modalities (rowing, biking, walking) can produce dramatically different symptom thresholds
• Morning heart rate variability (HRV) measurements provide objective feedback on recovery and exercise tolerance
• Repeatedly pushing past symptom thresholds creates negative neurological associations that worsen exercise tolerance
• Breaking the connection between exercise and symptoms may require changing equipment, environment, or exercise type
• Isometric exercises and proprioceptive training can help recalibrate the nervous system's response to movement
• Recovery isn't linear—success comes from tracking aggregate trends while accepting daily variability
• Focus on raising your "floor" (minimum exercise capacity on bad days) rather than chasing pre-injury performance levels
• Consistency in showing up for subthreshold exercise is more important than performance on any single day
