A new study finds that lowfat chocolate milk is an effective post-exercise recovery aid for soccer players, providing equal or superior muscle recovery compared to a high-carbohydrate recovery beverage. Chocolate milk's unique blend of protein and carbohydrates helps refuel exhausted muscles and reduce exercise-induced muscle damage.
A study by Indiana University researchers found that the ingestion of caffeine within an hour of exercise can reduce the symptoms of exercise-induced asthma (EIA). Smaller amounts of caffeine also reduced wheezing, coughing and other symptoms of EIA. The study extended earlier research on caffeine's effectiveness in reducing EIA symptoms.
A study by the Medical College of Wisconsin found that young female professional dancers face similar health risks as female athletes due to inadequate nutrition and menstrual irregularities.

Regular exercise has been shown to improve markers of heart disease in post-CABG patients, event-free survival rate in coronary patients compared to stent angioplasty, and endothelial function in heart failure patients. The benefits were seen regardless of age, with improvements in physical capacity, lipids, inflammation, and endotheli...
A study of 188 school children found that daily exercise reduced the prevalence of obesity by 29% and improved levels of HDL-cholesterol. Regular physical activity also increased exercise capacity and decreased systolic blood pressure in the children, with significant benefits observed even after just one year.
A Queen's University research team challenges the common belief that massage after exercise improves circulation to the muscle and removes lactic acid. Their study reveals that massage actually impairs blood flow to the muscle after exercise, resulting in impaired removal of lactic acid.
A study found that children who received more physical education time in school compensated by doing less at home, while those with less PE time made up for it by being more active at home. The researchers propose a central control mechanism similar to appetite in the brain, known as activitystat, which regulates physical activity levels.
A recent study suggests that exercises can improve symptoms of mild to moderate obstructive sleep apnea (OSA) by promoting remodeling of the upper airways. After three months, patients in the exercise group showed significant improvements in oxygen saturation levels, snoring symptoms, and quality of sleep scores.
A new study by Karolinska Institutet shows that extra support encourages more women to cycle to and from work, increasing daily physical activity levels. The intervention group achieved a larger proportion of cycling two kilometres or more per day than the control group.
Researchers found that exercise programs significantly reduced lung cancer symptoms in patients who completed the study, with no deterioration in functional capacity or muscle strength. The study suggests that community-based or shorter exercise programs may be more feasible for lung cancer patients to complete.
A new study from Brown University found that statewide weight loss competitions can be an effective way to promote weight loss in large numbers of people. The study, which evaluated the Shape Up Rhode Island 2007 program, showed that individuals who increased their activity levels achieved the best weight losses.
Researchers identified 19 volunteers with high dietary self-control and 18 without, showing differences in brain activity. The dorsolateral prefrontal cortex (DLPFC) modulates the ventromedial prefrontal cortex (vmPFC) to incorporate health considerations into decisions.

A new study by Ohio State University finds that most NCAA athletic trainers are not following best practice standards for managing asthma among athletes. The research suggests that a majority of programs are not adhering to national guidelines, which emphasize education, management protocols, and medical professional involvement.
A Temple-led study found that a two-phased program combining body image group counseling sessions and nicotine patches was more effective in helping young women quit smoking and maintain weight loss. The program showed an 18% rate of smoking cessation, compared to 8% for the exercise-only group.
A new University of Illinois study suggests that moderate exercise can reduce visceral fat inflammation, even without a change in diet. The benefits were apparent in both short-term and long-term studies, with significant reductions in belly fat and improved insulin sensitivity found in mice.
A study of over 2,000 seniors found that quitting smoking can slow down gait and improve overall health. Changing bad habits such as poor food choices and lack of exercise can also have a significant impact on senior health.
A study published at Experimental Biology 2009 found that regular exercise prevents the disruption of the blood-brain barrier caused by methamphetamine use. The study showed that exercising mice were protected from increased oxidative stress and permeability in the brain, while sedentary mice experienced damage.
A study of 227 breast cancer patients found that those with greater depressive symptoms and lower emotional quality of life were less likely to exercise as part of their recovery. Despite initial increases, physical activity declined over time, suggesting the need for future interventions to support long-term engagement.
Research reveals that exercising during pregnancy does not require sacrificing time for other activities. Exercisers actually spent slightly more sleep and reading time, while non-exercisers spent more on TV/computer time. The study also found significant differences in BMI and maternal weight between exercisers and non-exercisers.
A new study found that oral contraceptive use impairs muscle gains in young women, with lower hormone levels and elevated cortisol concentrations. The researchers also noted significant differences in lean mass gains between OC users and non-users.
Researchers found that maternal exercise was associated with increased fetal breathing movements and improved fetal heart rate variability. Fetal breathing movements are a marker of fetal well-being and reflect functional development of the respiratory system and central nervous system control.
Consuming a low-glycemic breakfast before exercise may boost fat oxidation during and after physical activity. A recent study found that this type of pre-exercise meal increased fat metabolism in sedentary individuals, potentially aiding in weight loss efforts.
A clinical trial found that exercise significantly improves the lives of heart failure patients by improving physical limitations, symptoms, and overall quality of life. The study, which enrolled over 2,300 patients, showed a five-point gain on quality-of-life measures for those who exercised, compared to those who received standard care.
Patients with moderate to severe heart failure who exercised regularly had a 11% lower risk of hospitalization or death compared to those who didn't exercise. Exercise also reduced the risk of death from cardiovascular disease and complications related to heart failure.
A clinical trial found that regular exercise significantly improved the quality of life for patients with chronic heart failure, reducing the risk of death and hospitalization. The study also revealed that exercise was well-tolerated and safe, with participants reporting fewer physical and social limitations.
Aerobic exercise training was associated with a modest reduction in the risk of death and hospitalization in patients with heart failure. The study found that exercise adherence decreased over time, but there was no significant difference in mortality rates between the exercise training group and the usual care group.
Pulmonary rehabilitation improves aerobic function, reducing breathlessness in COPD patients. Supervised exercise also decreases anxiety and depression by enabling patients to master new skills.
A new study suggests that astronauts need to modify their workouts to avoid extensive muscle loss during long-duration missions in space. Muscle biopsies taken from astronauts revealed an average of 15% muscle mass loss and 20-30% loss of muscle performance, posing risks to crewmembers' health.
Despite exercising for three months, octogenarian women failed to increase muscle mass, but showed improved efficiency in activating and synchronizing their muscles. The study suggests that it's essential to build as much muscle mass as possible earlier in life to ensure more strength in later years.
