EFFECTS OF TWELVE WEEKS HEALTH RELATED PHYSICAL FITNESS EXERCISE ON STUDENTS' ACADEMIC ACHIEVEMENT IN THE CASE OF WEGIDI GENERAL SECONDARY AND PREPARATORY SCHOOL GRADE ELEVEN FEMALE STUDENTS

The main objective of this study was to investigate the relationship between physical fitness and<br> academic achievement among Wegidi secondary and preparatory school grade eleven female<br> students. The study employed Experimental research design. From grade 11 female 98 total<br> population, 36sample students were selected with the age of (experimental group=16.00±0.766,<br> control group =16.33±0.685) and divided randomly into 2 equal groups. Both the experimental<br> group (number= 18) and control group (number = 18) participated in the typical one classes of<br> 40-minutePhysical education per week, but only Experimental group were participated in<br> additional 3sessions per week of 40 minutes per session of fitness training. Pre and post test<br> results of the selected fitness variables were taken from both groups. Cardio respirator fitness<br> was measured using 12minute run test, variables were tested by, Muscular endurance were<br> tested using pushups and Muscular strength were measured by using Wall-sit test, flexibility<br> were measured sit and reach variables were tested, body composition were measured BMI. The<br> data collected from the study subject was analyzed by using SPSS version 25 software. By using<br> paired t-test the mean differences/changes from pre to post test results of the variables and<br> students average score changes from first to second exam were checked. The results showed<br> health related physical fitness components such as CVE (MD=60.83), ME (MD=6.056) and MS<br> (MD=1.727), flexibility (4.556), were improved significantly following the 12-week fitness<br> Exercise in EG at (p&lt;0.05). Besides, body mass index (MD=-0.229) was significantly reduced,<br> since (p&lt;0.05). were significantly reduced, since (p&lt;0.05). However, he But, no significant<br> fitness improvement was found in all selected variables of CG (p&gt;0.05). Furthermore, the<br> correlation of most health-related fitness components of EG such as cardiovascular endurance<br> (r=0.798, p=0.039) and flexibility (r=0.589, p=0.017) have high and moderate positive<br> statistically significant relationship with students average score respectively, while body mass<br> index (r=-0.285, p=0.021) have low negative significant relationship with students’ Academic<br> achievement. But, Muscular endurance (r=0.129, p=0.654) and muscular strength (r=0.019,<br> p=0.941) have no statistically significant effect on students’ academic achievement. However,<br> health related physical fitness components of the CG have no significant effect on student’s<br> Academic achievement in all selected fitness variables. Therefore, the null hypotheses were<br> rejected in case of cardiovascular, body composition, and flexibility fitness variables, and<br> accepted in case of muscular strength and muscular endurance. Finally, the researcher<br> concluded that most health-related physical fitness components have a significant effect on<br> students’ academic achievement following the twelve-week health related physical fitness<br> exercises
