Using a dynamic finite-element breast–bra model and subsequent regression of a 25-run full-factorial design, the study quantified how the local Young’s modulus of five bra regions (cup C, side-front Sf, side-back Sb, band B, under-band U) controls peak contact pressure at four landmarks and 3-D breast range-of-motion (ROM). Pressure was governed mainly by the region […]

This paper presents a randomized crossover study in which twelve active males compared soft, semi-rigid and rigid 3D-printed polyurethane arch-support insoles during countermovement jumps, using SPM analysis of full-cycle force-plate and eight-camera motion data. Rigid and semi-rigid designs produced significant supra-threshold clusters (p ≤ 0.050) that increased ankle frontal- and transverse-plane kinematics and joint moments […]

In this randomized crossover study of nine active men, compression tights (CT) and compression shorts (CS) were compared with control shorts during countermovement jumps using 3-D motion-capture and force-plate data. SPM-ANOVA showed that, relative to control, CS reduced hip flexion angle by 25–36 % in propulsion and hip anterior force by 59–60 % in landing, […]

This study aims to investigate the biomechanical behaviour and the stiffness impact of the breast internal components during running.

The deformation elasticity behaviour of re-entrant auxetic structures with a bow-tie shape, made of silicone elastomer, is systematically analysed for size accommodation and shape conformity, and compared with traditional polyurethane foam and spacer fabric used in bra pads.

With the increasing need for personal protective equipment, textile-silicone composite structures are proposed in this study to reduce acute impact and moisture while enhancing thermal comfort.
