THE EFFECT OF HARMONIC EXERCISES ON ENHANCING SPEED STRENGTH, MAXIMUM RELATIVE OXYGEN CONSUMPTION AND SCORING IN FOOTBALL

Programs of sport training in the past were based on improvising, but now it became an educational process subject to principles that aim to prepare players completely to achieve the highest possible level in any type of sport activities. Harmonic exercises are used y trainers and athletes regularly due to its effect on performance efficiency. Harmonic exercises process is considered one of the important elements of preparing players even inside the training unit. The problem of the study lies in trainers’ non-interest of preparing training units and using improper exercises with the development of football which is became characterized by high fitness, functional and skilled abilities of players. The goal of the study is to determine the effect of harmonic exercises on enhancing strength speed, maximum limit of relative oxygen consumption and scoring in football. Hypothesis of the study: there are statistically significant differences at level (0.05α ?) between pre and post tests for the empirical and control group in the effect of harmonic exercises on enhancing strength speed, maximum limit of relative oxygen consumption and scoring in football. Methodology: the researcher adopted the empirical method as it is proper for the nature, problem and goals of the study. Population and sample of the study: the population of the study consisted of the 1st year students in the Physical Education Department, Faculty of Basic Education, Al Mostansereya University / 2015 (56 students). As for the sample of the study, it was chosen purposively of males only (36 males) after eliminating 20 female students (64% of total population). The sample is homogeneous as individuals were subjected to a testing battery for selection to be accepted in the department. The researcher divided the sample into two equal groups (18 students each) randomly. Harmonic exercises were applied in the first group (empirical group) for 25 minutes before starting the training unit, while the traditional method was used with the second group (control group). The researcher used parity and using legalized tests on the variables of the study. He made pre and post test and used multiple statistical methods such as arithmetic means, percentages, standard deviation, skewness coefficient, Pearson correlation coefficient and median for independent and equal samples. Conclusion and recommendations: efficiency of harmonic exercises prepared by the researcher and their properness to the nature of the study. The researcher found a clear development in enhancing strength speed, maximum limit of relative oxygen consumption and scoring as a result of using harmonic exercises. The researcher recommends the increase of time period of using training programs accompanying harmonic exercises.
