Abstract: BACKGROUND: The plantar pressure characteristics of the human body can effectively reflect the structure, function, mechanical characteristics, and posture control status of the foot. Age is an important factor that affects the characteristics of normal people’s plantar pressure.   
OBJECTIVE: To analyze the parameters such as plantar contact time, pressure impulse, contact area, peak pressure, peak pressure and other parameters of natural gait of 3-35 year-old healthy men, and to explore the differences and trends of plantar pressure characteristics of 3-35 year-old healthy men. 
METHODS: 200 healthy males were selected as the research objects. There were the group of 3-6 years old preschool children (group A), the group of 7-12 years old school children (group B), the group of 13-18 years old children (group C), the group of 19-25 years old youth (group D), and the group of 26-35 years old adult (group E), each group of 40 people. The Belgian foot scan USB plantar pressure detection system was used to detect the plantar pressure of the five groups of subjects under natural gait. The plantar dynamic contact time, pressure impulse, contact area, peak pressure, and peak pressure were observed. The implementation of the research plan complied with the relevant ethical requirements of Yanshan University for research. All subjects and their family members signed informed consent. 
RESULTS AND CONCLUSION: (1) The plantar contact time in the first phalange of toes (T1), metatarsal bones 1-5 (MH1-5), heel medial (RFM), and heel lateral (RFL) regions increased significantly with age (P < 0.05). (2) The plantar maximum pressure impulse mainly appeared in the T1, MH1, and MH3 regions, and the minimum pressure impulse appeared in the foot arch medial (MFM) region. The average plantar pressure impulse in the T1, MH1-4, RFM, and RFL regions increased significantly with age (P < 0.05). (3) The area of plantar contact increased significantly with age in T1, MH1-4, RFM, and RFL regions (P < 0.05). (4) The peak of plantar pressure increased significantly in the MH1-4 areas of the A-D groups (P < 0.05), and decreased significantly in the E group (P < 0.05). The peak of plantar pressure in the MH1, MH5, RFM, and RFL was fluctuating. The maximum pressure peak of the sole was concentrated in the MH1-3 areas. (5) The peak of plantar pressure increased significantly with age in the MH1-4 areas. The MH5, MFM, and MFL areas showed a volatility trend. The T1-5, RFM, and RFL areas increased significantly in the A-C groups and decreased significantly in the D and E groups. The pressure peaks in groups B, C, D, and E were significantly higher than those in group A (P < 0.05). It is indicated that with age, healthy men aged 3-35 years old have a longer plantar contact time under natural gait, and the largest plantar contact area shifts from the first phalanx to the inside of the heel. With the development of the foot, the weight-bearing parts of the foot appear heavy in the front and light in the back. Forefoot plantar pressure parameters increase, and the maximum pressure, impulse, and pressure on the plantar region are concentrated on the first, second, and third metatarsal bones. Therefore, in view of the change characteristics of plantar pressure parameters from preschoolers to mature years, choosing the corresponding shoes for daily life and exercise can effectively prevent foot injuries.
