A University at Buffalo study found that men with systolic blood pressure not rising above 140 mm Hg during exercise had increased risk of dying from heart ailments within three years. Careful blood-pressure measurements during routine stress tests could help identify patients at risk, allowing for early intervention and potentially sa...
A new study by exercise science researchers at the University at Buffalo found that wearing nasal strips has no effect on breathing during intense exercise. The strips may still be beneficial for individuals with exercise-induced asthma, however.
A study published in the American Journal of Epidemiology found that daily physical activities like climbing stairs and walking increased the risk of preterm birth among low-income women. In contrast, moderate exercise was shown to lower the risk of premature delivery by up to 50%.
A new book on composite materials has been published by Virginia Tech professor Michael W. Hyer, focusing on the mechanics aspects of fiber-reinforced composite materials. The book provides a comprehensive approach to understanding the stresses due to applied deformations, loads, and temperature changes.
A study by Deborah R. Young found that t'ai chi lowered systolic blood pressure in sedentary older adults, with significant effects seen after six weeks of exercise. The benefits were comparable to those achieved through moderate-intensity aerobic exercise.
A University of Florida study found that women who exercised at home lost more weight and maintained their progress longer than those in a group exercise program. The home-based workout group averaged over 25 pounds of weight loss, compared to 15 pounds for the group exercisers.
A study found that breast cancer survivors who exercised regularly experienced significant reductions in depression and anxiety, with improved mental health outcomes. The sooner they started exercising after surgery, the greater impact on their mental well-being.
A new study by University of Washington researchers found that commitment is a crucial factor in keeping New Year's resolutions. The study, which surveyed over 264 subjects, found that people who made strong initial commitments and had coping strategies were more likely to succeed.
Research by Joanne Schneider found that women who interpret their exercise experience positively tend to exercise more often, intensely, and for longer periods. In contrast, those who focus on bodily movements report exercising less often, less intensely, or for shorter periods.
Morbidly obese pregnant women can reduce their risk of developing gestational diabetes by engaging in moderate physical activity, a new study has shown. The study found that the presence or absence of exercise, not its frequency or duration, was the key factor in reducing diabetes risk.
Researchers found that frequent vigorous exercise reduces heart attack risk, with the greatest benefit seen in men who exercised five or more times a week. The study of over 22,000 physicians suggests that shorter exercise periods may also be beneficial for heart health.
A six-month aerobic exercise program improved the functional capacity, strength, and independence of heart failure patients aged 61-91. The study showed a 22% increase in physical fitness, with 43% of patients completing the trial and experiencing significant improvements.
Researchers found that chronic stress influenced daily activity rhythms and induced depressive-like behavior changes in mice. Exercise was more pronounced in animals without running wheels, suggesting its protective properties against stress effects.
The Plowshares Project enhances the US Army's Janus combat simulation model for emergency management events. TERRA simulates disasters and models effects on population and property. It also simulates individual field units and their actions in response to emergencies, facilitating interagency cooperation.
A study by Purdue University researcher James Binkley found that states with high fast-food sales aren't typically among those with weight problems, suggesting a possible link between reduced exercise and increased obesity. The research challenges the common assumption that fast food leads to weight gain.
A new study at Ohio University found that changes in muscle cells with aging limit muscle growth, and the number of special cells required for muscle growth decreases as people age. This reduction limits how much a muscle can grow.
A Duke University study found that short, vigorous workouts can temporarily reduce symptoms of depression by up to 82% in participants over 50. The results also showed an increase in feelings of vigor after the test.
Researchers found exercise had a significant impact on anxiety levels compared to sitting still, contradicting the notion that distractions can reduce stress. The study involved 34 college students who exercised in various settings and reported lower anxiety after exercise, with a peak at 15 minutes post-exercise.
Research shows that older adults have a decreased ability to oxidize fat during exercise, with only one-third the fat oxidation of younger counterparts. However, an intensive 16-week exercise program can help restore normal fat oxidation patterns in elderly individuals.
Researchers found that post-exercise meals containing amino acids and carbohydrates can enhance recovery and peak-performance levels. Eating oat-based cereal before exercise also helped fight fatigue and hunger.
