Balance and explosive strength exercises, are an integral part of preventive training programmes, especially for lower extremities injuries. Balance exercises may affect the development of explosive strength, through different mechanisms of adaptation.. The main purpose of this randomized controlled trial was to determine the effect of two different modalities of balance training on the development of explosive strength, assessed through jumping performance tests. This research was conducted on a sample of 39 healthy, physically active individuals (Z = 13, M = 26). Randomized subjects were divided into an experimental group - EN (N = 12), experimental group - the EU (N = 14) and control group - K (N = 13). Five week balance training was implemented for experimental groups. EN group conducted the training, which consisted of standing exercises; EU group conducted training with various plank exercises. Explosive strength was evaluated by menas of two jumping tasks (squat jump – SJ and countermovement jump – CMJ). The results of the two-factor analysis of covariance showed a significant increase of explosive strength jumping performance, in experimental groups compared to control group (p = 0.06 for SJ and p=0.48 for CMJ). It may be assumed that this is because both, balance and explosive strength performance rely on the capability of the body to promptly correct position in space. This study emphasizes the complementarity of balance and explosive strength. It confirms the possibility of applying balance exercises in order to develop explosive strength. The results can significantly improve the everyday coaching practice in sports injuries prevention. Results may also be useful in the field of functional rehabilitation considering lower extremity injuries. In conclusion, this study may provide scientific basis for planning balance exercise in order to develop explosive strength in the early stages of functional rehabilitation, or when an athlete, is temporarily unable to perform demanding plyometric trainings.
