12‑Week Walking Program Rewires Cognition in Older Adults
A supervised aerobic program lasting 12 weeks for sedentary adults aged 50‑80 in Saudi Arabia raised circulating irisin and brain‑derived neurotrophic factor while lowering leptin, oxidative stress and inflammatory cytokines. Metabolic markers such as blood glucose and VO2max improved, and cognitive test scores increased across participants, with the greatest gains—about 30%—observed in those with the poorest baseline brain health.

If You Want to Improve Your Breathing Performance on the Bike, You Need to Get Familiar With This Muscle
Cyclists often overlook the diaphragm, yet it powers the breath that fuels every pedal stroke. Research and expert insight reveal that many riders habitually breathe shallowly, using chest muscles instead of the diaphragm, which limits oxygen intake and hampers performance. Tightness in the diaphragm—caused by poor posture, back strain, or stress—can also impair spinal stability and balance. Simple breathing drills and targeted release techniques, such as foam‑roller and ball work, can restore full diaphragmatic function and boost cycling efficiency.
