This dataset included the body fat scores, which were used to conduct our second analysis. For this analysis, we had 345 body fat scores for 105 females during 260 IBIs (collected between 2008 and 2014). Scores were collected during July, August, or November of each year, and the timing of the score within the IBI varied across females. 183 fat scores were assessed during PPA, 70 during cycling, and 92 during pregnancy. For any given phase of a given IBI, females were usually assessed once, but in a few cases females were assessed twice during a given PPA (n=11). For these 11 cases an average body fat score was calculated so that each female contributed only one score for each PPA.
