The Contribution of Motor Memory to Certain Biomotor Abilities in the Digital Performance of the Long Jump for Students

Abstract

The research problem lies in the observation that some students possess good physical abilities, such as strength and speed, but their digital performance in the long jump does not reflect these abilities. This is likely due to a weakness in motor memory related to the perception of force, distance estimation, and controlling the rhythm of movement during approach and takeoff.

This study aimed to identify the level of motor memory for biomotor abilities: explosive power, speed-strength, maximum speed, movement speed, coordination, and agility, as well as to determine their relationship and contribution to the long jump performance score.

The research population consisted of 258 first-year students at the College of Physical Education and Sports Sciences, University of Babylon, during the 2024-2025 academic year. A random sample of 34 students was selected from Section B after excluding those who were injured, failed, or absent.

The researchers used a descriptive correlational approach and administered motor memory tests for biomotor abilities (tests conducted with eyes open and then retested with blindfolded), in addition to a long jump performance test. The data were statistically analyzed using SPSS software, calculating the mean, standard deviation, Pearson correlation coefficient, and coefficient of determination (R²) to determine the contribution percentages. The researchers concluded that motor memory for maximum speed and explosive power contributed most to performance, followed by speed-strength, then coordination and speed-action, while agility did not show a significant contribution. The research recommended focusing on maximum speed and explosive power training, developing motor memory through controlled repetition, and reducing agility training not directly related to the long jump.
