Year-long aerobic exercise program linked to slightly “younger” brain age on MRI, trial finds

A randomized clinical trial suggests that a year of guideline-level aerobic exercise was associated with small but measurable reductions in an MRI-based estimate of “brain age,” leaving participants’ brains looking close to one year younger than those of a usual-care control group.

94% of Hong Kong students lack exercise, 17.5% overweight, study shows

A Hong Kong government report shows about 94% of students do not get enough daily exercise, with 17.5% overweight. It also flags low fruit and vegetable intake, poor vision health and excessive recreational screen time among students.

Scientists explain how exercise shields brain from Alzheimer's

20 Mwezi wa pili, 2026 Imeripotiwa na AI

Researchers at the University of California, San Francisco, have discovered a mechanism by which exercise helps protect the brain from age-related damage associated with Alzheimer's disease. Physical activity prompts the liver to release an enzyme that repairs the blood-brain barrier, reducing inflammation and improving memory in older mice. The findings, published in the journal Cell, highlight a body-to-brain pathway that could lead to new therapies.

Longer uninterrupted walks reduce risks of death and heart disease

A large UK study of over 33,000 low-activity adults has found that accumulating daily steps in longer, uninterrupted sessions is linked to significantly lower risks of early death and cardiovascular disease, compared to short bursts of walking. The research, published in Annals of Internal Medicine, suggests that how steps are grouped matters as much as total step count for those walking fewer than 8,000 steps per day.

Longer continuous walks linked to sharply lower heart risk, study finds

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

28 Mwezi wa kumi, 2025 Imeripotiwa na AI

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.
