Abstract:
Aerobic exercises are more favorable to improving related physiological variables in youth athletes. The purpose of this study was to investigate the effects of aerobic exercise training on related physiological variables of male middle-distance athletes in the Aleltu woreda youth athletics project. To achieve the objective of this study, a true experimental research design was employed. The total population of the study was twenty (n=20) subjects. All subjects were taken as the sample of study by using the method of census sampling technique and then segregated into ten (n = 10) experimental groups (EG) and ten (n = 10) control groups (CG) by simple random sampling technique. The experimental group participated in exercise for eight weeks, three days per week in addition to their training program. The data were collected through pre and posttest of exercise on dependent variable of all subjects of the study. Then the collected data were analyzed using SPSS version 26. A paired sample t-test was used to analyze the mean, standard deviation, and significance difference between pre-posttest results of the study’s subjects. The significant level was set at p<0.05. As a result of the study, aerobic exercise had significant effect on VO2 Max of (EG) in the cooper test, (MD=4.20 l/min/kg), p=0.002, resting heart rate (MD = 2.300 beat/min, p = 0.003), and respiratory rate (MD=1.300 l/min/kg) p =0.001. However, the CG had no statistically significant change, on VO2 max in cooper test, (MD= -.630) (P=0.169), respiratory rate (MD=0.300 l/min/kg) p =0.193, RHR (MD = 0.200 beats/min, p =0.343. So the findings of this study revealed that aerobic exercise had a statistically significant effect on related physiological variables in the youth athletes. Therefore researcher recommends as the athletes and coaches incorporate aerobic exercise in to their training program to improve these variables
