LSM1 is the least-squares mean for Group 1 for each variable after dimensionless velocity has been taken into account. LSM2 is the least-squares mean for Group 2 for each variable after dimensionless velocity has been taken into account. 95% confidence intervals are given in parentheses. H0is the probability that LSM1 is equal to LSM2.

1

Stride frequencies and stride lengths were made dimensionless, and dimensionless velocity was the covariate.

2

Velocity was used as the covariate.

3

Dimensionless velocity was used as the covariate.
