Background & Purpose Development of astronaut partial gravity fitness standards as part of the performance optimization for lunar extravehicular activities readiness [polar] study Jakob Allen1,2, Nicole Strock1,2, Dillon Frisco1,3, Alyssa Varanoske1,2, Jonathan Hummel1,4, Brian Prejean1,2 1Exercise Physiology & Countermeasures Lab, NASA-Johnson Space Center, Houston, TX, USA; 2KBR, Houston, TX, USA; 3JES Tech, Houston, TX, USA; 4University of Houston, Houston, TX, USA BACKGROUND: Astronauts will need to be physically fit to complete Extravehicular Activities (EVAs) on future Lunar Missions Increased frequency , physical demand, intensity, duration of EVAs Compared to previous Apollo missions Current aerobic and muscular fitness standards for partial gravity EVAs require further research and validation to ensure crew are protected during Lunar surface missions 1.

Methods (cont’d) Supported by the NASA Human Research Program References Methods Literature review: Databases included in literature search included PUBMED, NASA Technical Reports Server (NTSR) + hand search, in which literature search was completed in November 2023 (PUBMED) and December 2023 (NTSR, hand search). For inclusion in this review, published manuscripts, technical reports, conference proceedings, and abstracts needed to include fitness (aerobic or muscle) data in relations to EVA task performance and/ or EVA (or simulated EVA) intensity outcomes. Exclusion criteria included review papers and manuscripts that did not report any fitness (aerobic or muscle) in relation to EVA task performance and/or EVA (or simulated EVA) intensity outcomes.
