A study found that aerobic exercise did not prevent aging-related bone loss, while higher body fat, especially in the abdomen, was linked to increased bone mineral densities. Muscle strength also played a role in maintaining bone health, contrasting previous studies suggesting aerobics could have a protective effect.
A study found that exercise and cognitive behavioral therapy improved fatigue, distress, mental health, and physical function in Gulf War veterans. Physical function improved more in those who received CBT, while mental health issues showed significant gains with exercise or both.

The study used a genome scan to find quantitative trait loci (QTLs) linked to aerobic running capacity and found significant associations on chromosomes RNO16 and RNO8.
Researchers found that fibromyalgia patients exhibit a blunted response to exercise-induced sympathetic nervous activity, indicating normal muscle physiology. The study also revealed no increased pain or fatigue in the post-exercise period, challenging previous assumptions about the role of physical effort in exacerbating symptoms.
Researchers discovered a protein enzyme called calmodulin-dependent protein kinase (CaMK) that controls mitochondrial production in muscle tissue, leading to improved metabolic properties. This finding has the potential to develop new drugs that mimic the effects of regular exercise for individuals unable to exercise.
A recent Ohio State University survey found that two-thirds of pregnant women believe walking and sex can induce labor. However, experts say these methods may not be effective and could pose health risks to the mother and baby. The study's author emphasizes the importance of waiting for natural labor to begin.
A study of 643 women found that C-reactive protein (CRP) levels are an indicator of increased cardiovascular risk in people with no signs of heart disease. Regular exercise has been shown to decrease blood pressure in all groups of people, regardless of their weight or ethnicity.
A new UF study demonstrates improved aerobic capacity in healthy elderly adults following both low- and high-resistance exercise training programs. This challenges the conventional view that strength training is not effective for improving cardiovascular and respiratory performance.
A study found that iron supplementation significantly enhanced maximal oxygen uptake and respiratory exchange ratio in iron-depleted women, improving their adaptation to aerobic exercise. Women with more depleted initial iron status showed the most improvement.
Research emphasizes the role of environmental factors in promoting physical activity, including accessibility, pleasant surroundings, and convenience. The study found that people are more likely to engage in outdoor activities when there are safe and accessible paths, bikeways, and health clubs nearby.
A University of North Carolina study found that individually tailored health promotion programs can significantly improve the lives of working women. The program, which included confidential feedback and lay health advisory programs, boosted fruit and vegetable consumption and improved strength and flexibility exercise among participants.
Two Johns Hopkins studies confirm the value of treadmill exercise tests in diagnosing heart disease before symptoms appear. Women with abnormal or inconclusive test results are up to 2.6 times more likely to die from cardiovascular disease, while men with similar test results are twice as likely to die from heart disease.
A University of Michigan study found that adolescent girls who feel confident about their physical abilities enjoy exercise more than those who doubt their skills. The research, led by Nola Pender, suggests that girls' perceptions and responses to exercise are linked to their confidence levels, with more confident girls reporting less ...
A study published in the Journal of Applied Physiology found that ultra-long-distance runners experience a decline in maximal voluntary force capacity due to central fatigue, but also exhibit strengthened twitch mechanical responses and unaltered M-wave characteristics.
A new study found that sustained caffeine intake counteracts the benefits of creatine supplementation, reducing muscle relaxation time and fatigue. This means that consuming high amounts of caffeine over a short period can negate the effects of creatine on exercise performance.
Regular intense exercise over nine months improved glucose metabolism in overweight individuals, with benefits persisting after cessation. The study found significant reductions in insulin levels and improvements in cardiovascular health.
Research with monkeys shows that low energy availability due to strenuous exercise training causes amenorrhea. Increasing food intake reverses the effect, suggesting a key role for energy balance in exercise-induced amenorrhea.
A Mayo Clinic study found that sildenafil does not worsen symptoms of inadequate blood supply to the heart muscle during exercise in men with coronary artery disease. The study, which involved 105 patients, suggests that sildenafil can be safely prescribed for these patients without increasing their risk of heart attacks.
A training program improved emergency physicians' ability to diagnose strokes via CT scans, leading to a significant increase in accurate diagnoses. Remote review of CT scans using teleradiology also showed reliable results in evaluating stroke patients for thrombolytic therapy.
A study suggests that robot-assisted sensorimotor therapy can help stroke survivors recover movement abilities years later. The robot exercises patients' limbs and rebuilds nerve pathways from the brain to the injured limb, leading to improved movement abilities.
A study suggests that kinking in the iliac arteries is a common cause of blood flow restriction in endurance athletes, particularly cyclists and speed skaters. Surgical release of these kinks can improve performance and enable athletes to return to competition, with 87% successfully returning to their desired level.
A new study found that a single session of moderately intense exercise improves cognitive function in people with chronic obstructive pulmonary disease (COPD), particularly in verbal fluency. The effects are cumulative, suggesting that regular physical activity is necessary to maintain mental benefits.
The study found that all participants exceeded their maximum heart rate target, with slow heart-rate recovery common among them. Dr. Murray Mittleman cautions against warning off players, instead suggesting regular exercise throughout the year to mitigate cardiac risks.
