| Abstract | ||||
| The academic study is an important phase in forming the individuals' future life where girls meet stressful studying events leading to anxiety, tension and low studying attainment and consequently studying at the college becomes disliked. Several scientists agreed that when the individual met a stressful situation a signal was sent via sympathetic nervous system to secrete catecholamine from the adrenal gland. Adrenalin is secreted by 80% and noradrenalin by 20% to help body face emergencies and physical stress positively. Practicing sports regularly helps increase producing some chemical substances and support their effects on the body. Such substances include endorphin which reduces the effect of adrenalin and hence assisting in removing tension and upgrading moral spirit and feeling positivity and happiness. Having reviewed Arabic and foreign researches in this field, the researcher noticed that aerobic dance and yoga programs were used separately to identify their effect on some psychological physiological and the level of performance in girls and hence, she decided to consider this research to combine benefits of aerobic dance and yoga in one program to know its effect on the level of adrenaline and beta-endorphin hormones and the level of physical and skill performance in motor expression in girls. The researcher used the experimental method to achieve the research objective and its hypotheses through a layout of the pre and post-measurements of one experimental group and a control group to suit the nature of the research. The research sample was selected intentionally from girls in the 3rd grade and included (30) girls by (54.9%) forming (10) girls as the experimental group, (10) girls as the control group and (10) girls for the pilot study. The program of combining aerobic dance and hatha yoga was applied for (10) weeks including (30) training units by (3) training units per week. Time of the training unit was graded from (30 to 60) min. The training load was increased from the lower limit of 65% to the upper limit of 85% of pulse rate. The results showed that the program of combining aerobic dance and hatha yoga had a positive effect on the level of adrenaline and beta endorphin hormones, the level of performance in motor expression and elements of flexibility and muscular strength. It was recommended that aerobic dance and hatha yoga be used within training programs for athletics in different sports and for male and female students at faculties of physical education to upgrade the level of performance. | ||||
