Simple breathing and walking exercises may speed lung recovery after COVID-19 pneumonia

This study investigates whether respiratory muscle training and walking exercises can improve lung function, reduce breathlessness, and enhance quality of life in women who have recovered from COVID-19 pneumonia. Eighty women aged 20 to 45 are divided into four groups: a combination of breathing and walking exercises, breathing exercises alone, walking alone, or no exercise. Researchers measure changes in breathing strength, lung capacity, exercise ability, and symptoms over eight weeks.
