Exercise boosts your brain
New research shows starting a new exercise routine spikes BDNF release—the brain‑boosting protein—making cognitive benefits strongest for fitness newcomers. (womenshealthmag.com). That’s a neat win for travel or training resets—new routines on the road or during a trip can give both body and brain a quick lift. (womenshealthmag.com)
The paper, “BDNF relates to prefrontal cortex activity in the context of physical exercise,” was led by Dr. Flaminia Ronca and is published online ahead of print in Brain Research (DOI 10.1016/j.brainres.2026.150253). (discovery.ucl.ac.uk) The trial initially enrolled 30 adults; 23 participants (7 female) provided venous blood samples and fNIRS data, and 20 participants completed the full set of three lab visits across the study. (antoniahamilton.com) Subjects followed a 12‑week cycling programme with three supervised sessions per week and repeated VO2max tests every six weeks to track changes in aerobic fitness. (ucl.ac.uk) BDNF concentrations were measured immediately before and after exercise testing, and the authors report that a single 15‑minute bout of moderate‑to‑vigorous aerobic exercise produced a reliable post‑exercise BDNF increase. (medicalxpress.com) The study found that as participants’ VO2max rose over the programme, the magnitude of the acute post‑exercise BDNF spike also increased, and those larger spikes were associated with changes in prefrontal‑cortex haemodynamics during attention and inhibition tasks but not with memory task performance. (discovery.ucl.ac.uk) Authors highlight that resting (baseline) BDNF did not change across the 12 weeks and that the results are exploratory with a small sample size, so the team urges further, larger studies to confirm the timing and cognitive specificity of the effects.
