Values are the net difference between groups of the percent change in variables from pre-camp to post-camp with 90% confidence limits (± 90% CL). Smallest Worthwhile Change in the variable, expressed as a percentage: SWC. Differences: Diff. Blood lactate concentration: [La]. Maximal oxygen consumption: VO2max. Running velocity at VO2max: vVO2max. Running time to exhaustion: TTE.
