Values for wheel running are least squares means ± s.e. from SAS Procedure Mixed for averages of days 5 and 6 of a 6 day test. Values for endurance speeds are also SAS least squares means and 95% confidence intervals, based on back-transformation from the square-root scale, for the higher of two endurance tests.
