تأثير التوقف عن التدريب في بعض المتغيرات المناعية للأطفال بعمر (11-12)‎ سنة

Abstract EN

Many researches concerned with studying the impact of sports training on the immune system.

this system is of importance in terms of its impact and influence in various body functions, however, this importance has not been researched fully in detraining period, especially for children who are affected greatly in the immunological changes that occur in the body.

the aim of the current research is to try to discover the following : • the influence of detraining on some values of the components of the immune system of children aged (11-12) years.

the researcher used the experimental approach design of a single group with pre and post-tests for its suitability to the nature of the research.

the sample of the study consisted of (14) children.

measurements were used as a tools of data collection.

which included the measurement of weight, height and measured of blood immune variables which included : (total and differential numbers of white blood cells, and immunoglobulin concentration).

the major experiment included : pre measurements and then application of aerobic training using interval training in low-intensity for two months, then post measurements were taken, in order to identify the impact of the training, and then training was stop for two weeks coincided with the period of ministerial exams ministerial to ensure that the sample did not practice any physical activity, after that post measurements were taken for the second time.

the researcher used the following statistical equations : calculated mean, standard deviation, coefficient of variation, t test for related samples, relative change formula).

after analyzing the data statistically the researcher concluded the following : the detraining period had significant impact on the neutrophils and lymphocytes.

the detraining period had no significant impact on the total number of white blood cells and cells eosinophil, basophil and monocytes, as well as on the level of immunoglobulin (IgA, IgG, IgM).
