Objective: This paper analyzes the relationship between the living habits and athletic ability of Mongolian teenagers, and clarifies the influence of living habits on athletic ability. Methods: Data from the 2014 Inner Mongolia Autonomous Region Student Physical Fitness and Health survey data and lifestyle questionnaire. Results: The boys who ate breakfast performed better on the whole-body endurance test than those who didn’t. The boys who have the habit of eating eggs have better muscular endurance, and the girls’ standing long jump test results were better than those who have no habit. The boys who have a habit of drinking milk performed better in the whole-body endurance test than those who have no habit of drinking milk. The results of grip strength, standing long jump and whole-body endurance test of boys who exercised for more than 1 hour were better than those less than. The boys who reached 1 - 2 times a week in physical education performed better in grip strength, 50 m running and whole-body endurance tests than the other two groups. The results of standing long jump of boys, sitting body forward bend of all and standing long jump, and muscle endurance of girls who reached 3 times a week in physical education were better than the other two groups. The standing long jump, 50 m run and muscle endurance test results of boys who took exercises for 1 - 2 times a week were better than the other two groups. The results of the sitting body forward bend of the boys and the 50 m running and muscle endurance test of the girls who did the class exercise more than 3 times a week were better than those of the other two groups, with significant difference (P < 0.05). Eating breakfast is an important factor affecting athletic ability.
