Which of the following is a precaution for participants with asthma?

Starting at low intensity and gradually increasing intensity is a key precaution for participants with asthma. This approach allows individuals to adjust to the exercise load while monitoring their breathing and overall comfort levels. For people with asthma, sudden increases in intensity can trigger symptoms such as wheezing, shortness of breath, or even asthma attacks. By easing into the workout, participants can better manage their condition and adapt to the physical demands placed on them, leading to safer and more effective exercise sessions.

The other options do not take into account the need for caution with asthma management. Immediate increases in intensity or jumping straight into high-intensity exercises can overwhelm the respiratory system, exacerbating asthmatic symptoms. Using only a heart rate monitor may not provide adequate information regarding the individual’s respiratory status and overall well-being during exercise, which is crucial for managing asthma effectively.
