Резюме: Objective: This work aims to identify the mass-inertial properties of the average Bulgarian male human body in several of NASA's standard astronaut positions. Materials and methods: Our approach is grounded in an enhanced 20-segmental biomechanical model of the male human body, created within a CAD/CAM computer environment. We validate the model by contrasting analytical outcomes for any of the body's segments with the results derived from the computer model. Results: We determine the mass-inertial characteristics of a male human body in different body positions for space exploration, as classified by NASA, using the available anthropometric data for average Bulgarian men. Discussion: We are confident that the suggested model can be used to calculate the relevant characteristics in question at any posture of the body of interest based on the comparison we made between our model results, presented in the current work and the analytical findings from our earlier research, as well as with data reported in the literature, where available. It is important to emphasize that although the model is applied to the typical Bulgarian male, it can be used for any gender, race, and individual, as long as the appropriate anthropometric measurements are performed. Conclusion: The model can be widely applied when parameters such as those studied are required to address issues arising in daily life, in the workplace, during leisure, rehabilitation, sport, ergonomics, criminology, space exploration involving astronauts, etc.
