Proprioceptive training is more and more integrated in sports performance, however effects in this area are not well-known. This study was aimed at determining the effect of 6 weeks of proprioceptive training on balance, strength and speed in sprinters. 33 medium-level sprinters were divided into two groups: a control group (no = 17) and an experimental group (no = 16). The training programme in the latter group included a proprioceptive programme consisting of 30 min/day using BOSU® and Swiss ball. Before and after the training programme, stabilometry tests were completed in the horizontal (X) and vertical (Y) planes, squat jump, counter movement jump and 30-metre sprint. Analysis of variance and covariance revealed beneficial impact on sprinter postural balance in the experimental group, as well as moderate increases in jump power with no impact on the sprinters' speed.
