The present study aimed to determine the effects of continuous and non-continuous training methods on athletes’ aerobic endurance levels among 30 long distance athletes at Dembecha Beruh Tesfa U-17 athletics project. 15athletes were assigned to continuous training group and the rest 15 grouped in to Non-continuous training. The researcher was employed quasi experimental research design and purposive sampling was used for this research, Then the mean chronological age and training age for continuous training group were found to be 15.73 and 3.2 respectively whereas15.733 and 3.33 for non-continuous training group. This study also used performance evaluation test, viz., 3 minute step test, 12 minute run test and 2.4km run test to measure the aerobic endurance level of athletes. Paired sample t-test was employed so as to compare the effect of these training methods whether there was a significant difference between pre and post test results after 8 weeks continuous and non- continuous training. In addition to examine the difference between the two groups result on athletes aerobic fitness, an independent sample t- test at alpha value of ≤ .05 was employed. The findings of this study revealed that non-continuous training group produces significant improvements in aerobic fitness tests better than continuous training method(i.e. in 3minute step test the mean score of non-continuous training group was84.2±1.567 and 86.4±1.549 at p=0.000 for continuous group , in 2.4 km run test the mean for non-continuous group was 0:07:05.34± 0:00:02.66 and 0:07:09.72± 0:00:03.65 at p=0.000 for continuous group, and in 12minute run test the mean for Non-continuous group was 2695.4 ±27.4 and 2673.5± 20.487 at p=0.000 for continuous group). Then the researcher concluded that 8 weeks of non-continuous training method was better in improving athlete’s aerobic fitness than continuous training method. So the recommendations are forwarded when outlining training sessions using non-continuous training method, coaches and athletes should consider the volume, intensity and durations of the recovery activities based on the intensity of work intervals.
