The study suggests that choosing a diet based on food preferences may make it difficult for dieters to scale down on the amount they eat.
A study by EULAR found that inspiratory muscle training (IMT) significantly improves lung strength and efficiency in AS patients, outperforming conventional treatment. After just eight weeks of IMT, patients showed improvements in chest expansion, aerobic capacity, resting pulmonary function, and ventilator efficiency.
A study found that physical activity declines over time in patients with chronic obstructive pulmonary disease (COPD), worsening lung function and health status. Sustained physical inactivity is associated with progression of exercise intolerance and muscle depletion.
Research suggests that light-intensity exercise can lead to improved health outcomes, including lower BMI and reduced chronic disease risk, for individuals over age 65. Engaging in 5 hours of light physical activity per week appears to provide similar benefits as moderate exercise.
Research suggests that aerobic exercise can curb asthma symptoms and improve quality of life by reducing bronchial hyperresponsiveness and inflammatory response. The study found significant improvements in symptom-free days, worsening symptom bouts, and quality of life scores among participants with moderate to severe asthma.
A faulty calcium channel in heart cells can cause a rare but potentially fatal heart condition called CPVT. When someone with the faulty gene exercises, adrenaline release can flood into the heart cells, causing a fatal arrhythmia.
Researchers question the validity of US dietary guidelines citing memory-based dietary assessment methods and their inability to accurately capture food consumption. Experts counter that multiple data sources can mitigate these issues, providing a more accurate representation of dietary habits.
Current practice of testing athletes at rest may miss signs of right ventricular dysfunction that can lead to sudden death. A new study shows that exercise echocardiography can detect changes in the right ventricle's functioning during physical activity, providing a potential diagnostic tool for cardiologists managing athletes.
Researchers found that older adults' cycling speed improved while completing cognitive tasks without sacrificing cognitive performance. The study suggests combining physical activity with mental tasks may encourage more vigorous exercise.

This approach has the potential to improve long-term survival and life expectancy for these patients.
A new study suggests that pulmonary rehabilitation can help reduce body mass index, improve pulmonary function, and decrease OSA severity in newly diagnosed patients. The treatment was found to be beneficial in addition to CPAP therapy.
A recent study found that youth dance classes offer only limited amounts of physical activity, with an average of 17 minutes of moderate-to-vigorous exercise per class. The CDC's guidelines recommend at least 60 minutes of physical activity daily for kids aged 6-17, but most dance classes fall short of this target.
A large cohort study found that even short duration and low intensity exercise has a negative correlation with mortality rate in the elderly. The risk of death decreased by 57% in those with higher levels of physical activity compared to those with lower levels.
A study published at the EuroPRevent congress found that employees in busy workplaces often do not meet recommended levels of physical activity, with only 6% achieving 10,000 steps per day. The research highlights the need for workplace health promotion policies to be more effectively applied to reduce cardiovascular disease risk.
Regular physical activity among elderly men is linked to a 40% lower risk of death from any cause. The study found that even light physical activity was associated with a significant reduction in risk, and those who engaged in moderate to vigorous physical activity lived five years longer than sedentary individuals.
A study by Kent State researchers found that using smartphones for texting, talking, or listening to music during exercise can negatively impact physical performance. Conversely, exercising with a phone without using it for communication or entertainment increased treadmill speed, heart rate, and enjoyment.
A recent review of combined diet and exercise training trials found that the effects differ across studies, suggesting more research is needed to determine their benefits for older people. Exercise training and diet supplementation have been shown to be effective in preventing muscle loss, but little is known about their combined effects.
A University of Alberta study found that prenatal exercise lowers the risk of Caesarean sections and larger-than-average babies. Women who exercised had a 31% lower risk of giving birth to an oversized baby without increasing the risk of smaller or earlier births.
A study by Dr Mark Moss and colleagues found that age has the biggest influence on motivators and barriers to exercise among older people. The researchers suggest that new health messages should tailor their information to account for differences between 'young' and 'older' older adults.
A new study published in Diabetes Care found that calorie restriction and exercise both improve insulin sensitivity, with combining the two approaches resulting in greater reductions. This suggests that both diet and exercise play important roles in managing Type 2 diabetes risk.
A UTMB study found that excessive weight gain during pregnancy, lack of exercise, and smoking are strongly associated with an increased risk of childhood obesity. Moderate exercise during pregnancy can lower this risk, even after adjusting for other factors.
A three-year study will enroll 2,000 adults aged 65+ who've had a fall-related fracture to assess the effectiveness of an exercise program integrating strength training, balance exercises, and walking with coaching. The study aims to reduce the risk of falls and fractures among seniors by addressing barriers to exercise
