ABSTRACT

The purpose of this study was to examine the effects of low-Dye tape on comfort and ground reaction forces (GRF) in flat-footed female runners. A randomized cross-over study was conducted on 15 flat-footed female recreational runners. Participants ran at three speeds (9, 10, 11 km/h) under two conditions: low-Dye and sham taping. Comfort level was assessed using a 150-mm visual analog scale. GRF data were collected using an instrumented treadmill. Stance time, peak forces, and loading rates were extracted. Low-Dye taping showed a lower comfort level (low-Dye, 63.8 (24.3) mm, sham 122.0 (16.0) mm, mean difference [95% confident intervals], -58.2 [68.2, 48.2] mm, p < 0.001). For all biomechanical variables, there was no interaction (taping condition a speed) effect or difference between taping conditions. As running speed increased, there was a decrease in stance time (p < 0.001) and increase in loading rate (p = 0.009), impact peak (p = 0.004), active peak (p < .001), breaking peak (p < 0.001), propulsive peak (p < 0.001), medial peak (p < 0.001), and lateral peak (p < 0.001). Compared with sham taping, application of low-Dye taping was less comfortable but did not alter running ground reaction forces among flat-footed female runners.
Key words: Peak force, loading rate, visual analogue scale, low-arch, non-elastic sports tape

Key Points
  • Female flat-footed runners were less comfortable with low-Dye taping than sham taping.
  • Stance time, peak forces, and vertical loading rate did not differ between low-Dye and sham taping.
  • There was no beneficial or detrimental effect of low-Dye taping across a range of running speeds (9 to 11 km/h).
