Rotational Traction Values on FieldTurf Revolution

As an athlete accelerates, stops, and changes direction, numerous forces are transmitted to the lower extremities. The interaction between an athlete's shoe and the playing surface has been indicated as a factor in lower extremity injury risk. In particular, high rotational forces may result in increased injuries to the lower extremities due to the foot becoming "entrapped" in the playing surface during pivoting movements (Torg et al., 1974).

The following list contains rotational traction values of various shoes tested on FieldTurf Revolution.

HSD* 10.8

*HSD: Tukey Honestly Significant Difference Test. Traction means within the value listed are not statistically different from one another.

Interpretation of Results

Rotational traction measured with mechanical devices such as Pennfoot allow for comparisons among shoe-types and playing surfaces; however, 'safe' and 'unsafe' traction levels have not been established in the scientific community, as this type of data has not been directly correlated with injury risk. Although researchers have yet to establish 'safe' threshold levels, it is generally accepted that low levels of rotational traction are desired over high levels from a lower extremity injury risk standpoint (Lambson et al., 1996). However, if traction is too low, playability may be reduced as athletes may be prone to slipping, thus increasing potential for other types of injuries.

Rotational traction values are presented in Newton-meters (Nm), which is the standard rotational traction unit (ASTM, 2009).

Traction data (four measurements per each shoe-surface combination) were analyzed for each playing surface using Analysis of Variance (ANOVA). Tukey's Honestly Significant Differences (HSD) test was used for means separation at the alpha = 0.05 level. It is important to note that traction values within the HSD value listed are not statistically different from one another.

Disclaimer: The traction values reported in this database represent the traction of each shoe under the conditions on the day of testing. Variations in traction values due to infill depth, infill composition, fiber type, surface wetness, air temperature, and other environmental conditions are possible. Additionally, athlete age, athlete weight, athlete skill level, and other attributes affect traction. Rotational traction values have not been directly correlated to injury risk.
