Asthma patients are advised to control which of the following during exercise?

Individuals with asthma are particularly advised to control their breathing rate during exercise due to the nature of their condition, which affects the airways and respiratory function. Asthma can cause the airways to become inflamed and narrowed, leading to difficulty in breathing, especially during physical exertion. Monitoring and managing the breathing rate helps ensure that the individual does not hyperventilate or exacerbate any asthma symptoms while engaging in physical activity.

Controlling the breathing rate allows asthma patients to maintain a steady airflow and reduces the likelihood of triggering an asthma attack. Maintaining a calm and consistent breathing pattern can help ensure that enough oxygen is delivered to the muscles without causing excessive strain on the respiratory system. This is particularly crucial during workouts, where fluctuations in breathing can lead to complications.

While the other options, such as heart rate, intensity, and muscle fatigue, are important factors in overall exercise management, the most critical aspect for those with asthma is maintaining appropriate control of their breathing to ensure they can exercise safely and effectively.
