| Objective: With 27 middle and long-distance runners from training and teaching classes as subjects, the study conducted experimental tests on runners wearing different types of insoles at the same speed and revealed the characteristics of plantar pressure and biomechanical pressure parameters during running, so as to provide a theoretical biomechanical basis for the study of middle and long-distance runners. Methods: The study adopts experimental methods, literature review, expert interviews and mathematical statistics, as well as a plantar pressure testing system and processing software for data organization and analysis. Results: When middle and long-distance runners wore different types of test insoles while running, the average plantar pressure and maximum pressure on the left and right feet in eight distribution areas varied. Pairwise comparison and repeated measures ANOVA revealed significant differences, indicating that the heel area is the main force-bearing region during the landing and buffering phase of running. Conclusion: ①When barefoot, the plantar pressure in the M2, M4, M5, and M6 areas of both left and right feet is greater than that of the other three types of insoles. Except for the M3 area, the plantar pressure in other areas is greater when barefoot than with the other three types of insoles. ②The M5 (2nd-4th metatarsal area) and M6 (1st metatarsal area) are the main force-bearing areas during the push-off phase of running. The M1 (heel area) is the primary force-bearing region during the landing and buffering phase of running. ③When barefoot, there are significant differences in the plantar pressure values of the M2, M5, and M6 areas of both left and right feet, and in the maximum pressure values of the M2, M4, M5, and M6 areas of both left and right feet, compared to the other three types of insoles. ④The plantar pressure and pressure values indicate that type A insoles perform better in terms of pressure reduction and shock resistance. |
