ABSTRACT
Objective:
To understand the influence of sports fatigue on plantar pressure distribution of healthy male college students and provide a theoretical basis for improving their awareness of foot health.
Methods:
Forty-nine ordinary male college students jogged along the 800-meter runway to moderate fatigue. All the subjects took off their shoes and socks and walked naturally with their usual gait. The dynamic plantar pressure of each foot was measured twice in one step. FootscanUSB2 Belgian flat-plate plantar pressure testing system was used for testing.
Results:
The average dynamic peak plantar pressure was (206.38 44.59) N for boys, and the changes of AA and CB walking speed in the arch did not change significantly. After fatigue, the peak pressure of FM, AA, RH5 in left foot and FM, AA, CB in right foot decreased significantly (P < 0.05, P < 0.01). The peak time of RH and CB in the left foot was significantly shorter than that before fatigue (P < 0.05, P < 0.01), while FMF, AA, C areas had no significant change but tended to be delayed. There were significant differences in peak force-time between boys’ left and right feet except for the fifth metatarsal bone (P < 0.05). There is a significant difference in the peak force-time between the second and fifth toes of the left foot (P< 0.01), and there is a gender difference in the peak force-time between the second metatarsal and the third metatarsal (P < 0.05).
Conclusion:
Sports fatigue leads to the decrease of physiological functions such as muscle strength of lower limbs, which leads to the corresponding changes in gait stages, plantar pressure distribution parameters, and foot balance. Level of evidence II; Therapeutic studies - investigation of treatment results.
