Effects of traditional Chinese exercises on brain-derived neurotrophic factor in middle-aged and older adults: A systematic review and meta-analysis of randomized controlled trials
Brain-derived neurotrophic factor (BDNF) may help middle-aged and older adults resist age-related neurodegenerative conditions and psychiatric disordeā¦
A meta-analysis of 10 randomized controlled trials found that ancient forms of Chinese exercise were associated with significant increases in a protein linked to memory, mood, and brain cell health.
Researchers pooled data from participants in their 50s, 60s, and 70s. All three major traditional Chinese exercise forms (Tai Chi, Baduanjin Qigong, and Yijinjing Qigong) showed meaningful associations with higher BDNF levels.
BDNF (brain-derived neurotrophic factor) is sometimes described as fertilizer for the brain. It supports neuron growth and maintenance, and plays a role in how well your memory and mood systems function.
The researchers believe the benefit may come from the combination of movement and mindfulness, rather than from physical effort alone. Earlier research on low-to-moderate exercise without a meditative component showed weaker BDNF responses.
The scientists believe that breathwork and focused attention reduce stress hormones that suppress BDNF production while simultaneously activating the neural pathways that promote it.
If you already practice Tai Chi or Qigong, this adds to the case for keeping it. If you don't, the programs studied used beginner-accessible 8- and 10-form sequences easily found on YouTube or in community center classes, no equipment required. Two to three sessions per week covered the range of what was studied, with no evidence that dramatically higher volumes improve results.
If youāre already exercising consistently, you donāt need to replace your current routine. Instead, think of the research as one more reason to try something you might have overlooked.
