Least squares means (standard error in parentheses) of arrest distance and impact load classified by the type of rope, rope length, and their interaction. Least squares means followed by the same letter are not statistically different (P > 0.05) by Tukey’s Honestly Significant Difference test. For combinations of rope and distance, statistical comparisons were made between distances within each rope.
