Statistical Analyses
Statistical analyses were completed using JMP software (version 11; SAS Institute, Cary, NC, USA). Student’s t-tests were used to test if there were differences by position or seniority at preseason (p # 0.05 considered significant). Out-come measures were changes in weight and changes in whole body and regional lean and fat mass. Postseason changes (Post) were calculated as postseason minus preseason measure and indicate the changes over the competitive part of the season, whereas spring season changes (Spring) were spring season minus postseason measure and indicate changes during the off-season. The change at Post or Spring was considered significantly different from zero if the 95% confidence interval (CI) of the mean change in the outcome measure excluded zero.
