An abundance of information can be found in the scientific literature regarding the bilateral deficit (BLD) in different contraction types, including its possible underlying mechanisms. On the other hand, studies on the relationship between BLD and physical performance have only begun to emerge in recent years. The purpose of this article was to carry out a detailed review of the literature on the topic of the relationship between BLD and physical performance. After a detailed review of the scientific databases, we analyzed 7 relevant scientific articles. BLD calculated from outcomes of ballistic contractions (jumps) was positively related to the ability to change direction quickly, but the findings were not confirmed by all studies. Sprint running performance does not to be associated with BLD, while one study suggested that a smaller BLD is associated with a more efficient start in sprint. In one study, training with predominantly bilateral exercises increased BLD and improved the ability to quickly change direction and sprint time more than a comparable training with bilateral exercises. In the only study not conducted on athletes, a negative impact of BLD (calculated from rate of force development outcome) on sit-stand performance was noted in postmenopausal women. So far, there is little evidence to support the association between BLD and physical performance, thus, further research is needed.
