A 12-week cycling program increases aerobic fitness and makes the brain release more BDNF in response to a single 15-minute workout; fitter participants show larger BDNF spikes and stronger prefrontal cortex activity during attention and inhibition tasks, with the boost tracking with VO2max gains, suggesting fitness amplifies the brain’s response to exercise.
The author tested OpenAI's ChatGPT Health and Anthropic's Claude by uploading a decade of Apple Health data (and later medical records) to obtain a simple cardiac-health grade. Outputs swung widely—ChatGPT gave an F, then a D after adding records; Claude varied between C and B—driven by noisy VO2 max estimates and changing resting heart-rate data. Experts say the analyses are not medical advice, and privacy promises to protect data aren’t HIPAA-covered. While AI health tools could unlock insights, the article argues they’re not ready for personal clinical decisions and should mainly support prepping for a doctor visit.
Norwegian scientists have developed a fitness age calculator that determines the age equivalent of one's fitness level based on markers of cardiovascular health, such as exercise habits and oxygen utilization. A lower fitness age is associated with reduced risk of heart disease, depression, and other health issues. The calculator, available online, aims to provide a more accurate predictor of longevity than traditional metrics like BMI. Regular aerobic exercise can help reduce fitness age, and studies have shown strong correlations between higher aerobic fitness and improved cardiovascular health outcomes.
