Exercise likely to be best treatment for depression in coronary heart disease

A study by RCSI indicates that exercise is probably the most effective short-term treatment for depression in people with coronary heart disease, when compared to antidepressants and psychotherapy or more complex care.

The study, led by researchers at RCSI University of Medicine and Health Sciences, is published in the June edition of Psychosomatic Medicine.

This is the first systematic review to compare treatments for depression in those with coronary disease and the findings provide valuable clinical information to help doctors determine the best treatment plan for patients.

The researchers reviewed treatment trials which investigated antidepressants, psychotherapy, exercise, combined psychotherapy and antidepressants, and collaborative care (i.e. treatments devised by a multidisciplinary team of clinicians with input from the patient).

To measure effectiveness, the researchers looked at factors including patient adherence to the treatment (dropout rate) and change in depressive symptoms eight weeks after commencing treatment.

The strongest treatment effects were found to be exercise and combination treatments (antidepressants and psychotherapy). However, as the combination study results have a high risk of bias, the findings of the review suggest that exercise is probably the most effective treatment. Antidepressants had the most research support, while psychotherapy and collaborative care did not perform very well.

Those Late-Night Snacks May Be Hurting You at Work

A recent study finds that unhealthy eating behaviors at night can make people less helpful and more withdrawn the next day at work.

“For the first time, we have shown that healthy eating immediately affects our workplace behaviors and performance,” says Seonghee “Sophia” Cho, corresponding author of the study and an assistant professor of psychology at North Carolina State University. “It is relatively well established that other health-related behaviors, such as sleep and exercise, affect our work. But nobody had looked at the short-term effects of unhealthy eating.”

The study, is published in the Journal of Applied Psychology.

Exercise boosts blood flow to the brain

The results add to growing evidence that exercise programs may help older adults slow the onset of memory loss and dementia. It’s not just your legs and heart that get a workout when you walk briskly; exercise affects your brain as well. A new study by researchers at UT Southwestern shows that when older adults with mild memory loss followed an exercise program for a year, the blood flow to their brains increased. The results were published online today in the Journal of Alzheimer’s Disease.

Drinking a strong coffee half an hour before exercising increases fat-burning

Scientists from the University of Granada also found that, if the exercise is performed in the afternoon, the effects of the caffeine are more marked than in the morning

Scientists from the Department of Physiology of the University of Granada (UGR) have shown that caffeine (about 3 mg/kg, the equivalent of a strong coffee) ingested half an hour before aerobic exercise significantly increases the rate of fat-burning. They also found that if the exercise is performed in the afternoon, the effects of the caffeine are more marked than in the morning.

In their study, published in the Journal of the International Society of Sports Nutrition, the researchers aimed to determine whether caffeine—one of the most commonly-consumed ergogenic substances in the world to improve sports performance—actually does increase oxidation or “burning” of fat during exercise. Despite the fact that its consumption in the form of supplements is very common, the scientific evidence for its beneficial claims is scarce.

Face masks don’t hinder breathing during exercise

Face masks do not hinder breathing during exercise - استفاده از ماسک در هنگام ورزش باعث اختلال در تنفس نمی شود

Exercise performance and blood and muscle oxygen levels are not affected for healthy individuals wearing a face mask during strenuous workouts.

Findings are of importance because they indicate that people can wear face masks during intense exercise with no detrimental effects on performance and minimal impact on blood and muscle oxygenation

Exercise Can Slow or Prevent Vision Loss, Study Finds

Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests.

The new study from the School of Medicine found that exercise reduced the harmful overgrowth of blood vessels in the eyes of lab mice by up to 45%. This tangle of blood vessels is a key contributor to macular degeneration and several other eye diseases.
