Nonfeasance is defined as:

Nonfeasance is defined as the failure to perform a legal duty or an obligation that one is required to fulfill. In the context of athletic training, this means that a healthcare professional is neglecting to provide the necessary action or intervention when it is required by their professional responsibilities. For instance, if an athletic trainer is expected to assess an athlete's injury but fails to do so, that individual may be committing nonfeasance.

This concept is particularly critical in the field of healthcare and sports medicine, as it underscores the importance of fulfilling one's duties to ensure the safety and well-being of athletes. Professional standards dictate that certain actions should be taken to prevent harm, and failing to act can lead to legal repercussions and negative outcomes for patients or athletes. Recognizing the implications of nonfeasance is vital for ensuring both compliance with legal standards and the provision of appropriate care.
