摘要：Purpose. The present study assesses the extent to which delayed mechanical feedback affects technical and numerical long jump performance.Methods. The participants were 45 first-grade students from the Department of Physical Education of Umm Al-Qura University. They were randomly divided into 3 equal groups. The first experimental group used delayed mechanical feedback, the second experimental group applied fast visual feedback, and the control group received oral explanation and guidance of a teacher. The delayed mechanical feedback condition lasted for 6 weeks. Each week included 2 units, each lasting for 90 minutes.Results. The educational programs had a significant main effect on technical and numerical long jump performance (p < 0.05), with a large effect size, as the percentage of improvement ranged 9.95–42.32%. Also, the differences across the 3 groups were statistically significant in terms of their technical and numerical performance (p < 0.05), favouring the mechanical feedback group, except for the difference between the fast visual feedback and the teacher guidance groups.Conclusions. The delayed mechanical feedback program had a more significant positive effect on technical and numerical long jump performance than the other 2 programs.
