The main purpose of this study was to evaluate or find out effects of continuous training on some selected physical fitness components and selected physiological variables at Debre Selam Secondary and Preparatory School male students’ football player team. The studies employed Quantitative research approach and a true experimental research design. For the achievement of the purpose, 26 male football player students were selected by census (parcial purposive sampling technique and were divided randomly into 2 groups, at which group one got treatment with the continuous training method (N = 13) and group two was a control group (N = 13). The age of the participant ranges from 15 to 18 years. Each variable was measured by each recommended test method and procedure: cardio respirator fitness was measured using a 12-minute run test (cooperator test), muscular endurance was tested using a 900 push-up, flexibility was measured by a sit-and-reach test, speed was measured in a 30-meter dash run test, agility was measured in a zigzag and T-ship agility test, resting heart rate was measured in counting at radial arteries(clinical instrument sphygmomanometer)., respiratory rate was measured by counting the number of inhalation and (mercury metro meter) clinical instrument, and blood pressure by clinical instrument (sphygmomanometer). The researcher used SPSS version 26 software for data analysis. By using the mean, standard deviation, paired sample t-test, and independent sample t- test the data was analyzed, a conclusion was made, and the recommendation was forward. Mean differences/changes from pre- to post test results of the variables were determined to determine the significant improvement and dis improvement of the result for each variable. The results showed on physical fitness component and physiological variables such as Cardiovascular endurance, muscular endurance, flexibility, selected physiological variables were resting heart rate, respiratory rate, and systolic and blood pressure were significantly improved at level confident (P< 0.05), whereas partial speed, agility, and diastolic blood pressure were not improved at level confident (P > 0.05).. Generally, depending on the finding, the experimental group showed a better significant improvement than the control group.
