Age-based analysis of virtual stress in cycling leggings using a 3D clothing simulation

This study analysed virtual stress in cycling leggings to identify age-related differences in wearing comfort. Using a 3D virtual fitting programme, virtual stress was measured in static and cycling postures for avatars representing average Korean males in their 20s to 60s. The front waist showed higher pressure than the back waist, with individuals in their 20s exhibiting the highest pressure despite having the smallest waist circumference. Hip pressure was influenced by both body circumference and volume, highlighting the importance of three-dimensional body characteristics. The thigh showed relatively small pressure variation, whereas the knee exhibited the largest increase and fluctuation during cycling, indicating the need for highly stretchable materials. Calf pressure varied by posture and location, suggesting careful seam placement. Although ankle pressure was relatively low, unstable changes indicated the need for additional support. These findings demonstrate that age-related body shape variations affect regional clothing pressure in cycling leggings.
