In vivo ‐determined muscle protein synthesis assessed during the four phases of the estrus cycle. Regularly cycling female rats were staged using vaginal smears and protein synthesis determined using ³H‐phenylalane incorporation into muscle protein. Values are means with the minimum and maximum values indicated by upper and lower bars, respectively; n = 10 per group with individual values plotted for each group. There were no statistical differences between groups based on one‐way ANOVA with Student–Newman–Keuls (SNK) post hoc test.
