Table 2.

A Huynh-Feldt, repeated measures ANOVA was used to examine the effects of the independent variables, torso flexion, weight, speed, and direction, on the dependent variable, lumbar curvature as a percentage of range. Epsilon from the Mauchly’s test of sphericity and the Huynh-Feldt adjusted degrees of freedom (df) are reported. The F-statistic and the significance (p) are also reported. Significant results (p<0.05) are highlighted.
