“The present study was based on a progressive, moderate intensity exercise programme to minimise the risk of injury. This study is unique in its application of jumping in multiple directions, suggesting that this is not only safe, but an effective method of developing athletic performance. In the attached podcast, Lee Taft discusses the role of multidirectional development in athleticism, suggesting some of the ways he incorporates drills which allow “free play”, and then evolves them into more complex and extensive change of direction tasks.
In the absence of growth-related hormones seen in children, the authors suggest that the improvements seen in this study are most likely associated with improved neuromuscular performance. Furthermore, as a result of improved muscle-tendon behaviour in the agonist and antagonist muscles during jumping, improvements in the concentric (squat jump: = +11.14%) and plyometric (countermovement jump = +9.91%) were seen. However, measuring strength alongside this, with the use of a handheld dynamometer, for example, would have supported this claim. In conclusion, such a program should be appealing to coaches as it requires very little time to complete, whilst showing some impressive results.”
