The tennis player exhibits primary exercise dependency.
Step-by-step explanation:
Working out for such a long period may lead to consequences that will show after a few years. It will lead to a compulsive engagement in the routine over few years of she continues to do so. For the coming years, this will lead her to a state of dependence on the routinely excessive practice.
