Based upon the data presented in this investigation it can be concluded that static stretching oers no benet when compared to a standing control when examining vertical jump performance. The authors suggested that neither protocol optimized jumping performance and suggested that athletes utilize warm-up protocols which activate the stretch-shortening cycle and were dynamic in nature as these types of warm-ups appear to optimize jumping performance.
