| ABSTRACT | |||
| The aim of the present study was to determine the effect of patellar
taping (PT) on landing characteristics of the vertical ground reaction force
(VGRF) and on flight time during a counter movement jump (CMJ). Eleven healthy
male subjects (age: 31.1 ± 4.2 years) volunteered for the study. Each subject
performed six CMJs under two different jumping conditions: with PT and without
PT (WPT). The order of the two conditions was randomized. All of the measured
variables had fair-to-good reliability (intra-class correlation coefficient
> 0.75). When we compared the PT and WPT groups, we did not find a significant
difference in the magnitude of the first (F1) and second (F2) peaks of the
VGRF. We also did not find a significant difference in the time to production
of these peaks (T1 and T2), and the time to stabilization (TTS) (p <
0. 05). Furthermore, the flight time was similar in the two groups (0.475
± 0.046 and 0.474 ± 0.056 s, respectively, for PT and WPT). These results
suggest that PT does not jeopardize performance during CMJ. Furthermore,
it also does not soften the VGRF generated during the landing, indicating
that PT may be of limited utility in preventing injuries associated with
this type of movement. Key words: Biomechanics, force platform, vertical ground reaction force, landing phase. |
