TLDR;
This TEDx Talk explores the connection between mental toughness, physical exercise, and a protein called Brain-Derived Neurotrophic Factor (BDNF). It highlights how activities like planking, which require both physical and mental effort, can significantly increase BDNF levels, potentially improving mental resilience and quality of life. The talk emphasizes that grit is not just about willpower but is also rooted in biology, with BDNF playing a crucial role.
- Grit is linked to biology, specifically BDNF.
- Planking, requiring mental and physical effort, boosts BDNF.
- Increased BDNF may improve mental resilience and quality of life.
Introduction: The Power of the Plank [0:21]
The talk starts by describing the experience of holding a plank, emphasizing the physical and mental challenges involved. It then introduces George Hood, who set the world record for the longest plank in history (10 hours, 10 minutes, and 10 seconds). The speaker met George eight years prior when he set the record at that time, five hours, and was struck by his mental toughness and focus. George attributed his success to the plank being 90% mental, distracting himself and drawing energy from the environment.
Grit and BDNF: The Biological Connection [2:42]
The speaker introduces Brain-Derived Neurotrophic Factor (BDNF), describing it as "fertilizer for your brain." BDNF is a protein that supports the growth, health, and communication of neurons, crucial for memory and mental resilience. While factors like sunshine, blueberries, and antidepressants can increase BDNF, exercise is the most effective method. The plank, a simple yoga pose, is presented as a potentially powerful exercise for building mental toughness by increasing BDNF levels.
Clinical Research and Real-Life Examples [3:43]
The speaker, a clinical professor and diplomat in the Department of Preventive Medicine at UCSD, discusses her clinical research involving patients facing severe medical conditions. While acknowledging that planking cannot cure these conditions, she suggests further research into its potential benefits is warranted. She highlights the compelling examples of individuals enduring devastating conditions, such as Daniel, who suffers from Complex Regional Pain Syndrome (CRPS), one of the most painful diseases.
The Science Behind BDNF and Exercise [5:34]
The speaker references a 2005 study in the journal Hippocampus, which found that physical exercises requiring mental focus produce more BDNF than purely physical exercises. Activities like yoga, which combine physical effort and concentration, have been shown to produce some of the highest levels of BDNF ever measured. The speaker is designing a study to investigate whether planking can relieve pain in individuals like Daniel with CRPS.
Recent Findings and Call to Action [7:21]
The speaker mentions a 2024 article in Experimental Neurobiology that found exercise doubled BDNF levels. She aims to raise awareness about the relationship between exercise, BDNF, and improved quality of life, advocating for further research in this area. She concludes by challenging the audience to incorporate planking into their lives as a way to build grit and potentially transform their mental and physical well-being.
