Which action is recommended to prepare a client with asthma for exercise?

• A. Warm up for 10 minutes with HR 50-60%
• B. Begin with maximal effort
• C. No warm-up necessary
• D. Hydration only; no warm-up

Answer: (A)

A structured, moderate warm-up helps a client with asthma exercise more safely by preparing the airways and heart for activity. Starting with about 10 minutes at a moderate effort (roughly 50–60% of maximum heart rate) gradually raises body temperature and the temperature and humidity of the airways. This reduces airway cooling and mucus thickening that can trigger bronchoconstriction, making exercise more tolerable and often easing the transition into higher-intensity work. In many people with asthma, this kind of gradual ramp-up also creates a brief protective window—sometimes called a refractory period—during which the airways are less reactive, lowering the risk of exercise-induced bronchoconstriction as activity begins or increases. Hydration alone or skipping a warm-up does not address the airway reactivity that asthma can cause with exercise, and starting at maximal effort is more likely to provoke symptoms. Having a useful, moderate warm-up sets the stage for safer, more comfortable exercise and helps the client perform closer to their capacity.
