Critically ill patients in ICUs can benefit from mild physical therapy exercises to reduce muscle wasting and promote recovery. The new approach involves introducing muscle-strengthening exercises early into treatment plans, with patients exercising while on ventilators and other life-support equipment.
Postmenopausal women can improve cardiovascular fitness and reduce risk factors for chronic diseases through regular, vigorous exercise. Studies show that even less strenuous aerobic exercise produces benefits, and women's metabolism changes after menopause affect glucose clearance from the blood.
A new study led by Queen's University aims to clarify Canadian exercise guidelines, which suggest 20-30 minutes of vigorous activity or 45-60 minutes of walking for health benefits. The research will investigate the specific type, amount, pattern, and intensity of exercise needed to achieve optimal results.

The research challenges traditional advice and suggests a slowly progressive weight-lifting routine can be beneficial for women with lymphedema.
Researchers found that taking dexamethasone prophylactically improves exercise capacity, oxygen uptake kinetics and decreases anaerobic threshold in HAPE-susceptible climbers. Dexamethasone reduces pulmonary artery pressure and has anti-inflammatory properties, but also carries significant side effects.

African-American women experienced the greatest benefits, especially post-menopause, while racial differences may be attributed to genetic variations.
A University of Iowa study found that kids who were active at age 5 had less body fat by ages 8 and 11. Even small increases in physical activity, such as an extra 10 minutes per day, can make a difference in protecting against excessive fat gains.
