Effects of concurrent and sequential training of maximum strength and oxygen endurance on certain components of the body composition

Abstract

The study aimed at being acquainted with the effects of concurrent and sequential training of maximum strength and oxygen endurance on certain components of the body composition in addition to the differences between those two types of the training at the post test for the same variables. The experimental method was used. The study conducted on a sample of 20 subjects from the "Athletic Qaraqush Club". The sample divided into two groups with 10 subjects each. The homogeneity and equality were achieved in variables of age, high, weight and certain components of the body composition. The procedure of the study included determining the maximum intensities of the endurance and external weights for setting the intensities that will be used in the trainings. Two pilot studies were conducted. The first one was for the adopted exercise in the study and the second one was for conducting a training session. After that, the final field procedures were applied which started at pre tests of the body composition components followed by applying the two curricula of the concurrent and sequential trainings which lasted 9 weeks with 3 meso cycles. Each meso cycle included 3 micro cycles with (2:1) workload wave and with 3 training sessions per a week for the concurrent training and 6 training sessions per a week for the sequential one. Finally, the posts tests were conducted using the same procedure for the pre tests. After using the SPSS package to process the data, the conclusions were as the following:  The first experimental group, which applied the concurrent training, significantly decreased the fat weight and significantly increased the body weight.  The second experimental group, which applied the sequential training, significantly decreased the fat weight and significantly increased the free fat weight, body water and body weight.  There were significant differences between the two groups of the concurrent and sequential training in the free fat weight, body water and body weight so that they were tended to increase with the sequential training and decreased with the concurrent one. The most important recommendations of the study were to emphasize on coaches to use the concurrent training for improving the maximal strength, oxygen endurance, fat weight reduction, free fat weight, body water and body weight; and to emphasize on coaches to use the sequential training for reducing the fat weight in addition to raise the free fat weight, body water and body weight.
