| This study conducted an athletic training questionnaire among 258 male amateurs who completed the 2016 Beijing Marathon and Shanghai International Marathon and physical fitness tests . 193 people who completed the match within the specified time and meanwhile completed the injury investigation within a week after the match were included in the study. According to the new grading standards in 2018: 118 people are listed in Group A , 65 in Group B , 10 in Group C The results showed that there were significant differences among the three groups in the weekly training rate [Group A (9.6±3.4) km / h, Group B (11.8±4.0) km / h, Group C (13.7±6.4) km / h]; there was a significant difference in resistance training between Group A (56.2%) and Group B (66.2%), Group C (70.7%) ; there were significant differences (P<0.05) in interval training among the three groups (Group A 40.6%, Group B 50.2%, Group C 69.8%); there was a significant difference in hopping relative value and symmetry between Group A (78.53%±12.43%, 73%±13%) , and Group B (85.37%±12.80%, 81%±14%), Group C (91.70%±11.43%, 87%±12%); and there was a significant difference (P<0.05) between Group C (61.00±62.27) times and Group A (24.90±27.91) times, Group B (35.95±26.40) times. The study shows that the major training differences of amateur marathoners at different levels are the participation in resistance training and interval training; the muscle strength characteristics related to sports performance include the hopping relative value and symmetry as well as the number of crunches; and there is no difference in the lower limb stiffness. |
