Interlimb asymmetries have been recently investigated in athletic populations. However, the effects of training interventions on interlimb asymmetries have been scarcely examined. Therefore, the aim of this study was to determine the effects of training interventions on changes in interlimb asymmetries from pre- to post-training. Furthermore, to examine the effects of training programs on intervention groups compared with control groups. A database search was completed (MEDLINE, CINAHL, and SPORTDiscus). Eight studies were then included in the meta-analysis. Results showed small reductions in interlimb asymmetries in single-leg broad jump (SLBJ) and change of direction (COD) speed from pre- to post-training interventions, whereas moderate effects were found in single-leg countermovement jump (SLCMJ) and SL lateral jump. When comparing the training interventions with the control groups, results showed small effects in favor of the training groups for reducing interlimb asymmetries in SLBJ and large effects in SLCMJ and COD speed. Thus, training interventions can evoke small to moderate reductions in interlimb asymmetries from pre- to post-training programs. Strength training performed unilaterally or bilaterally may elicit these reductions. Furthermore, training interventions showed larger effects compared with the control groups in reducing interlimb asymmetries. However, further research is needed.

This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.
