No. Question
1a What is the relative risk of sustaining a traumatic and/or stress fracture for a given decrement in bone mineral density, or alteration in bone geometry, in an astronaut-equivalent population who are physically active?
1b Will a period of rapid bone loss in hypogravity be followed by a slower rate of loss approaching a basal bone mineral density (BMD)? What are the estimated site-specific fracture risks as one approaches basal BMD?
1c Is there an additive or synergistic effect of gonadal hormone deficiency in men or women on bone loss during prolonged exposure to hypogravity?
1d What biophysical modalities, nutritional modifications, and pharmacological agents (alone or in combination) will most effectively minimize the decrease in bone mass due to extended hypogravity exposure?
1h Does the hypogravity environment change the nutritional requirements for optimal bone health?
1i What diagnostic tools can be utilized during multi-year missions to monitor and quantify changes in bone mass and bone strength?
1j What systemic adaptations to hypogravity are important contributory factors to bone loss, evaluations of which are essential for effective countermeasure development (e.g., fluid shifts, altered blood flow, immune system adaptations)?
1k Are hypogravity-induced changes in bone density, geometry, and architecture reversible upon encountering partial gravity exposure, or on return to full gravity (1-G)?
1l What regimen (exercise, pharmacological, nutritional, or biomechanical including impact loading or artificial gravity exposure) will most effectively hasten restoration of bone mass and/or bone strength (geometry and architecture) to pre-flight values in returning crewmembers?
2a Is the rate of fracture healing and the integrity of the healed fracture altered under hypogravity or unloaded conditions?
2b Are there site-specific differences or differences in healing diaphyseal bone versus metaphyseal bone under microgravity or partial-gravity conditions?
