Which symptom could indicate abuse occurring in an athlete?

Chronic stomachaches in an athlete could indicate abuse occurring because they may be a physical manifestation of emotional distress or psychological trauma often associated with abusive situations. Such symptoms can frequently arise from stress, anxiety, or fear that may stem from an unhealthy or unsafe environment. In the context of abuse, these physical symptoms may not have an obvious medical cause and can signal that something is wrong beyond typical training or performance pressures.

On the other hand, continuous training success, increased enthusiasm for sports, and consistent social gatherings suggest positive experiences and engagement in an athlete's life, typically associated with healthy participation in sports. These do not align with indicators of abuse, as they reflect functionality and fulfillment rather than symptoms of distress or suffering.
