Fig 1 Generalized regression plot. Abbreviations: Area A, above threshold velocity; below average force or push frequency; Area B, above threshold velocity; above average force or push frequency; Area C, below threshold velocity; above average force or push frequency; Area D, below threshold velocity; below average force or push frequency. Legend: The solid line is the linear regression line based on existing data. The dashed line is the extrapolated linear regression line. Threshold velocity is represented by a dash-dot line. Solid line ellipse is the 95% covariance ellipse. Dashed line ellipse is the 75% covariance ellipse.
