The Curve of Change for The Effect of Speed and Endurance Trainings on on some immune variables amongst swimming beginners

The aim of this study was to investigate the curve of change for the effect of speed and endurance trainings on some immune variables amongst swimming beginners. To achieve that, the study was conducted on a purposive sample that consisted of (24) beginner swimmers of Jerusalem Governorate, and they were equally distributed into tow groups: the first group (G1) that undertook the speed trainings, and the second group (G2) that undertook the endurance trainings. The experimental approach was used in its method the repeated measures for the suitability of the study objectives, and a training program of speed and endurance was implemented for (8) weeks with (3) training units per week. To collect data, lab tests were conducted before starting the training program, during the (4th) week, and after finishing the training program for the study variables of: (White Blood Cells (WBC), lymphocyte, Eosinophill, and Neutrophill). After the data collection, SPSS software was used to analyze it. The results of the study showed that there were no statistically significant differences at (p ≤ 0.05) in the curve of change for the effect of speed trainings (G1) on some immune variables among swimming beginners. Also, the results revealed that there were statistically significant differences at (p ≤ 0.05) in the curve of change for the effect of endurance trainings (G2) on all immune variables among swimming beginners. Finally, the results indicated the presence of statistically significant differences at (p ≤ 0.05) in the post-test (third measurement) of the effect of speed and endurance trainings on immune variables in a favor of the endurance training (G2) in all study variables. The study recommended the generalization of the study findings on swimming coaches, sport clubs, associations, and swimming federation in order to get benefit in the preparation of training programs.
