The research aimed to identify the effectiveness of educational platforms using the Blackboard system in improving mental alertness and the level of technical and digital performance in the long jump competition. Divide them into two groups, one of them is an experimental group and the other is a control group, each consisting of (15) students, Among the research tools: physical tests - mental alertness scale - intelligence test - assessment of the level of technical and digital performance in the long jump - educational program using educational platforms using the Blackboard system. The statistical methods used: arithmetic mean - standard deviation - median - skew coefficient - simple correlation coefficient - t-test - improvement ratios. Among the most important results: 1- Educational platforms using the Blackboard system have a positive, statistically significant effect at the level (0.05) on mental alertness and the level of technical and digital performance in the long jump competition for first-level female students in the Department of Sports Sciences, College of Education - Taif University - Saudi Arabia. 2- The learning style by command has a positive and statistically significant effect at the level (0.05) on the level of technical and digital performance in the long jump competition, while there are non-statistically significant differences in mental alertness. 3- The superiority of the educational platforms strategy over the order-learning method in the dimensional measurements and the percentages of improvement in the dimensional measurement over the tribal in mental alertness and the level of technical and digital performance in the long jump competition. Among the most important recommendations: 1- Using educational platforms by following the Blackboard system to improve mental alertness and learn and master the long jump competition for first-level female students in the Department of Sports Sciences, College of Education - Taif University - Saudi Arabia.
