EFFECTS OF AEROBIC EXERCISE IN THE MORNING VERSUS AFTERNOON ON PHYSICAL FITNESS AMONG SPORT SCIENCE MALE STUDENTS AT WOLLO UNIVERSITY.

The purpose of the present study was to compare the effects of aerobic exercise in the morning<br> versus afternoon on health-related physical fitness variables following the physical fitness<br> training period in the case of sport Science male Students of Wollo University, pre and post-test<br> data and manipulation of the cause and effect relationship between independent and dependent<br> variables, the researcher used the quasi-experimental design. A simple random sampling<br> technique was used to assign morning and afternoon groups. Therefore, fifteen (15) subjects<br> were assigned to the morning training group and fifteen (15) subjects’ afternoon training group.<br> Both groups participated in aerobic training workouts for 8 weeks 3 days per week a total of 60<br> minutes. The parameters selected for the study were a 3-minute step test for cardio-respiratory<br> fitness, push-up and sit-up test for muscular endurance, sit-reach test for flexibility, and skin fold<br> test for body composition. Pre-posttest were conducted for all 30 subjects on all health-related<br> physical fitness variables and the score was recorded. Data collected from health-related<br> physical fitness variables measurements were analyzed through descriptive statistics (mean ±<br> Standard deviation) and paired sample T-test (Mean difference, Standard deviation mean, and<br> significance levels), and independent t-test to analyze and compare the statistical (mean)<br> difference between the results of two groups of posttest at a significant level of 0.05. The findings<br> of this study revealed that the afternoon group produces significant improvements better than the<br> morning group. The AG and MG independent t-test mean results of cardio-respiratory fitness<br> were, (96.84± 9.032 and 104.00± 9.768 at p=0.046), muscular endurance (40.13±6.390 and<br> 35.26±5.133 at p=0.029) and (40.400±3.418 and 37.06± 3.750 at p=0.017), flexibility (11.26±<br> 5.560 and 6.066± 5.391 at p=0.015) and body composition (9.636± 1.367 and 10.86±1.490 at<br> p=0.026) respectively. The present study showed that the afternoon group has significance<br> effects on all health-related physical fitness variables. Based on the finding the researcher was<br> eager to recommend that aerobic exercise should be given in the afternoon to enhance the<br> performance of health-related physical fitness.
