Abstract
The current research aims to reveal the differences between the two measurements (pre and post tests) in the values of some segmental body composition for three groups of exercises (maximum strength, strength endurance and strength characterized by speed). Additionally, the research aims to reveal the differences between measurements and post-tests for the three research groups in the values of a number of body composition and its parts.
The researchers used the experimental method for its suitability and the nature of the research. The researchers deliberately selected the research population from the students of the third stage, Department of Physical Education and Sports Sciences, College of Basic Education, University of Mosul, for the academic year (2022-2023). They were distributed among the three research groups randomly, and the final number of the sample was The research included (30) students divided into (9) students for the first experimental group (maximum strength), (8) students for the second experimental group (strength extension), and (13) students for the third experimental group (strength characterized by speed).
The number of training units for the training curriculum was (24) training units, at (3) training units per week for (8) weeks. The researcher used the following statistical methods: (arithmetic mean, standard deviation, t-test for corelated samples, one-way analysis of variance, and transmission ratio). The statistical package (Spss) was used to analyze the data. .
The researcher reached at a set of conclusions, the most important of which were the following:
When comparing the two pre-measurements to identify the effect of the three training programs on the measured physical characteristics, a clear difference emerged between the pre- and post-measurements for all physical variables and for the three research groups (maximum strength, strength endurance and strength characterized by speed).
When comparing the three research groups (maximum strength, strength endurance and strength characterized by speed) in the post-measurements of the measured physical characteristics, it was revealed that a small difference appeared between the three research groups, except for the variable (force characterized by speed (Squatting)), which showed a clear change between the research groups. All three.
When comparing the three research groups (maximum force, strength endurance, strength characterized by speed) in the post-measurements of body composition variables and its parts, it was revealed that a slight difference appeared between the three research groups.
