Approximately 250,000 ACL injuries occur in the United States each year (Silvers & Mandelbaum, 2011). At least half of these injuries occur in young athletes (Griffin et al., 2006). Fatigue is thought to be a contributor to injury risk, however, the extent of this association during sports participation has yet to be identified. Previous research has used standardized protocols in order to induce fatigue and study its effect on human performance. Unfortunately, it is unknown whether these protocols induce a level and type of fatigue that is representative of sports participation. Therefore, the purpose of this study was to compare the performance alterations as a result of fatigue experienced after basketball participation to that of two fatigue protocols during a jump landing. The results show that performance changes that occur as a result of functional and general fatigue protocols were not like those observed after participation in basketball competition. Future research should attempt to address this issue when studying fatigue and incorporate protocols that are validated to represent sports participation.
