A study of 58 adults found that four widely used fitness watches frequently overstated energy expenditure during a controlled cycling workout when compared with clinical metabolic equipment. The size of the error varied by device and tended to increase with participants’ body-fat levels, while Fitbit produced inconsistent readings that limited its analysis.
A six-month randomized controlled trial of 93 women found that postmenopausal participants assigned to aerobic exercise improved task-switching and error management more than those in a stretching-and-toning group. The gains appeared after three months and continued through the study, while memory and processing speed did not show the same improvement.
A population-based study of 2,266 working-age people in Finland found that evening-oriented participants, particularly extreme evening types, reported more difficulty recovering from work and more mental health symptoms or diagnoses than morning types. The association with anxiety disorders appeared connected to work-life spillover and inadequate recovery, but the study did not establish that being a night owl causes these problems.
In the randomized NEXAF trial, a tailored exercise program combining initial supervised sessions with longer-term home exercise and digital monitoring reduced the amount of time participants spent in atrial fibrillation. The intervention also improved fitness and was associated with fewer hospitalizations, but it did not significantly improve atrial-fibrillation-specific quality-of-life scores.
A study published in Imaging Neuroscience found that 10 minutes of very slow treadmill running was followed by improved mood, faster performance on a measure of executive function, and increased activity in several prefrontal brain regions. The research examined running at roughly walking speed and very light exercise intensity.
Updated American Heart Association/American Stroke Association guidance highlights rehabilitation that may begin within days of a stroke and address movement, communication, cognition, sleep, nutrition and mental health. The guidance also emphasizes that recovery is often a long-term process involving survivors, caregivers and a multidisciplinary care team.
Professional gaming can involve prolonged sitting, repetitive hand movements, extended screen time and intense mental demands. Reporting in Medical Xpress highlights the injuries affecting players and the growing use of physical therapy, ergonomics, exercise and psychological support—while researchers explore lessons from musicians, dancers and other performers.
The European Society of Cardiology has published its first guidelines devoted specifically to cardiac rehabilitation, bringing together recommendations across multiple heart conditions. The guidance emphasizes individualized programs combining exercise, emotional support and education, while also addressing digital home-based care, access barriers and the role of patient preferences.
An exploratory comparison in adults aged 65 and older, alongside rat and cell experiments, linked greater habitual activity with higher hip bone-density scores, lower TMAO, reduced inflammatory markers, and a bone-turnover profile favoring formation. The findings suggest a possible gut–bone inflammatory pathway, but the human results were observational rather than proof that exercise caused the differences.
A McGill University-led study of 54 healthy young adults found that either 20 minutes of moderate-to-vigorous cycling or a 90-minute nap was associated with better image-memory performance after 30 hours without sleep. Brain recordings suggested the two interventions supported memory through different neural processes, but neither replaced sleep.
