<p>&nbsp;&nbsp;&nbsp;&nbsp;Here we report a case study on coaching in handball with the objective of providing knowledge useful for practice. To this end, coaching by an instructor (author) who directed a college female handball team was examined and discussed, focusing on the teamʼs defense and fast break tactics. The following aspects became clear: 1) When employing a tactical concept, it is necessary to properly understand the risks of the tactics itself, and be thoroughly prepared to compensate for them. 2) Defense and offense tactics have a mutual influence on each other; therefore, how adopted defense tactics might affect the teamʼs offense tactics need to be considered. In terms of coaching, it is important to incorporate tactical training into overall training.</p>
