Data are mean ± SE and were collected approximately 60–90 days preflight (L-60) and 7 and 30 days postflight (R + 7 and R + 30). CON control group that performed the ISS standard of care exercise prescription, SPRINT experimental group that performed a high intensity/lower volume exercise prescription.

*Simple main effect for time relative to preflight (P < 0.05).

**Simple group × time interaction effect relative to preflight (P < 0.05).
