A study found that almost one-fifth of asthma parents believe exercise is dangerous for their children, leading to lower physical activity levels. Children with moderate or severe asthma are also less likely to engage in high levels of physical activity due to parental misconceptions.
A study found that regular exercise, as well as routine activities like walking for transportation or performing household chores, can reduce a woman's risk of endometrial cancer. The research team assessed physical activity from various periods in life and found significant benefits for women with higher levels of physical activity.

A randomized controlled trial suggests that modest exercise, such as 30 minutes of daily walking, can not only prevent weight gain but also lead to additional loss of weight and fat. The study found a dose-response effect between the amount of exercise and decreases in measurements of central obesity and total body fat mass.
A recent study found that even moderate amounts of exercise can help prevent weight gain in overweight individuals. The research, published in the Archives of Internal Medicine, suggests that more intense physical activity is necessary for weight maintenance and that a modest amount of exercise can reverse positive caloric imbalances.

A USC study found that physical activity can reduce the risk of breast carcinoma in situ (BCIS) by up to 35%, particularly among women who exercise more than four hours a week. The exact mechanism is unclear, but hormones and immune-boosting effects are potential theories.
Researchers investigated chronic pain management through surveys, questionnaires, and studies. The results highlighted the importance of pain treatment outcomes, associations with health-risk behaviors, and post-traumatic stress disorder relationships. Additionally, a new exercise program improved arm and hand recovery after stroke.
A study found that exercise increases BDNF and neurogenesis in mice, but high levels of these chemicals don't necessarily improve learning. In fact, high-running mice perform poorly in maze tests, suggesting a potential 'tipping point' where too much exercise becomes detrimental.
Researchers found that resistance exercise can alter the expression of clock genes in human skeletal muscle, causing a phase shift similar to winding on (resetting) the muscle clock. This suggests that peripheral clocks can regulate themselves independently of the central clock.
A study published in The Journal of the American Medical Association found that women who performed below average in peak exercise capacity and recovery rate were more likely to die from heart disease. Regular exercise was shown to combat risk factors, with moderate physical activity improving exercise capacity by 15-30%.
Researchers found significant racial and sex differences in nasal contribution to breathing during exercise, with African-Americans having a greater nasal contribution than Caucasians. Women had significantly less physical work capacity and breathing efficiency compared to men.
Caffeine was found to reduce thigh muscle pain in young adult men during cycling exercise, suggesting its potential as a pain relief aid for endurance activities. The study's results may help explain why prior reports showed that caffeine improves exercise performance.
Researchers found that women exercising 250-300 minutes per week and reducing calorie and fat intake lost up to 15% of their body weight in about six months. They also increased cardiorespiratory fitness compared to baseline values.
Research found that moderate-intensity physical activities like walking, biking, or swimming can reduce breast-cancer risk in postmenopausal women by about 20 percent. Regular exercise also offers a similar protection among high-risk groups, such as those with a strong family history of breast cancer.

Notably, blacks, American Indians, and those with lower education and income levels reported less favorable neighborhood environments and reduced access to exercise spaces.
A recent study found that older women who live in neighborhoods with good walkability are up to 100% more physically active. Women who live near parks, trails, or shops have higher levels of activity than those whose homes are not within walking distance.
A Mayo Clinic study found that middle-aged and older adults who engage in regular aerobic exercise can maintain increased insulin sensitivity for up to four days after their last workout. However, this effect is not seen in those over 40, highlighting the importance of frequent exercise for preventing or treating Type 2 diabetes.
Scientists tested a synthetic earthquake on a half-real building with conventional and simulated steel support columns. The experiment, called the 'Multi-Site Online Simulation Test,' used grid-linked machines to create a realistic simulation of an earthquake, producing a profusion of real-time data.
A study found that exercising in front of a mirror reduces women's energy, relaxation, and positivity. This effect persists even among those with good body image, suggesting mirrors may hinder physical activity motivation. The findings have implications for exercise promotion guidelines and the use of mirrors in workout centers.
