Quantification of In-flight Physical Changes - Anthropometry and Neutral Body Posture (NBP) (Completed)

Last Published: 11/23/20 11:55:12 AM (Central)

Task Book: Entry
Principal Investigator: Rajulu, Sudhakar

Short Title: Body Measures

Responsible HRP Element: Human Factors and Behavioral Performance

Collaborating Org(s):

Anthropometry & Biomechanics Facility (ABF)

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Directed

Aims:

To quantify microgravity effects on body measurements, including lengths, breadths, widths, circumferences, and joint angles of astronauts exposed to microgravity in an unsuited condition,
To determine if and how the neutral body posture (NBP) is influenced by changes in body size/shape and microgravity effects.

This study increased our knowledge by quantifying how the body’s size and shape changes due to spaceflight. This study also revealed how NBP can change after specific types of movements. The data obtained from this study can be used in design and verification of suite, vehicle, and habitat design.

This study contributed towards the gap closure of HAB-02 by identifying the human physical changes (body size, body shape, and NBP) that occur during a mission.

Mappings

Risk of Adverse Outcome Due to Inadequate Human Systems Integration Architecture

HSIA-401: We need to determine how HSI can be applied in the vehicle/habitat and computer interface Design Phase to mitigate potential decrements in operationally-relevant performance (e.g. problem-solving, execution procedures), during increasingly earth-independent, future exploration missions (including in-mission and at landing).

Quantification of In-flight Physical Changes - Anthropometry and Neutral Body Posture (NBP)

Risk of Injury from Dynamic Loads

OP-401: We do not know the extent to which multiple spaceflight hazards (e.g., spaceflight deconditioning, bone loss, radiation exposure, altered gravity) may interact to synergistically decrease injury tolerance for off-nominal dynamic landing loads, increasing risk to crew’s performance in mission-completing actions immediately after landing.
