Heather Vogel Larawang ginawa ng AI Fact checked
Walking in bouts of 10–15 minutes or longer was associated with substantially lower cardiovascular risk among adults taking fewer than 8,000 steps a day, with 15‑minute‑plus bouts tied to about a two‑thirds lower risk than very short walks, according to research published in Annals of Internal Medicine.
Men over 50 need more exercise than women for heart benefits
A new study reveals that men over 50 must exercise nearly twice as much as women to achieve similar reductions in coronary heart disease risk. Using data from activity trackers, researchers found significant sex differences in exercise benefits for heart health. The findings suggest a need for updated, gender-specific health guidelines.

A new study reveals that decades of endurance exercise, such as running and cycling, may keep the immune system youthful and resilient in older adults. Researchers found that natural killer cells in trained individuals functioned better, showed lower inflammation, and resisted fatigue under stress. The findings suggest physical activity trains the immune system much like it does muscles.
Study identifies aerobic exercise as top relief for knee osteoarthritis
A comprehensive review of over 200 studies has determined that aerobic exercises such as walking, cycling, and swimming provide the most effective pain relief and mobility improvements for people with knee osteoarthritis. Published in The BMJ, the analysis emphasizes aerobic activity as the foundation of treatment. All tested exercise types proved safe, with no increased adverse events compared to controls.
Running reverses junk food's depressive effects in rats
New research from University College Cork shows that voluntary exercise can counteract the mood-damaging impacts of a high-fat, high-sugar diet in rats. The study highlights specific gut metabolites and hormones that explain these benefits. However, poor diet still limits brain neurogenesis despite exercise.
