With digitisation in garment engineering and virtual prototype and modelling techniques becoming more mainstream, a new generation of virtual human models starts to develop to fulfil the demand for protective and functional products designed for specific athletes, such as climbers and mountaineers. We must base our work on an improved understanding of the behaviour of the musculoskeletal system to develop garment patterns that minimise discomfort and improve performance under dynamic body deformations and muscle contractions associated with specific movements. For this study, we explored the possibilities of using existing software packages for virtual prototyping based on human kinematic models for functional clothing. Keywords: clothing design, digitalization, kinematic human model, virtual prototyping 1. INTRODUCTION Patternmakers are still developing clothes based on the standard anthropometric static protocol defined by ergonomic standards or size charts: standing and looking straight ahead, with shoulders relaxed, arms at sides, and legs hip widespread [1]. When the size charts do not cover the requirements of personal protective equipment, there are measurements during movements as standing, sitting, kneeling, etc. [2]. Since the human body is engaged in permanent movement, and the demand for functional garments for work or sportswear is a modern concern, understanding how the human body alters in dynamic is an essential and contemporary research topic. In current practice, dynamic anthropometry in the clothing industry was first applied for functional and aesthetic sportswear products [3]. Because functional clothing, especially for sports athletes, has complex requirements regarding increased physical comfort, performance, ease, and range of motion, the 2D flat pattern methods fail to capture the complex form of the human body shape in movement. In this case, an efficient method that can enhance body mobility and fitting test in movement is using 3D human body data and 3D technology in order to develop clothing. Several changes have been implemented to bring virtual humans closer to our everyday lives in the past years. These human body models can be found in many interactive applications for virtual reality (VR) and augmented reality (AR), including games, movies or commercials. Virtual prototyping is usually based on avatars, garment patterns and textile materials. In the garment industry, most virtual models use realistic virtual representations of humans based on 3D anatomy scan data or used to the body measurement standard charts.
