TY - JOUR PY - 2014// TI - The effect of uphill and downhill walking on joint position sense JO - Journal of sport rehabilitation A1 - Bottoni, Giuliamarta A1 - Heinrich, Dieter A1 - Kofler, Philipp A1 - Hasler, Michael A1 - Nachbauer, Werner SP - 349 EP - 352 VL - 24 IS - 4 N2 - CONTEXT: During sport activity knee proprioception might worsen. This decrease in proprioceptive acuity negatively influences motor control and therefore may increase injury risk. Hiking is a common activity characterized by a higher intensity exercise phase during uphill walking and a lower intensity exercise phase during downhill walking. Pain and injuries are reported in hiking especially during the downhill phase.

OBJECTIVE: The purpose of this study was to examine the effect of a "hiking-fatigue-protocol" on joint position sense.

DESIGN: Repeated measures. Setting: University research laboratory. PARTICIPANTS: Twenty-four non-professional sportswomen without knee injuries took part in this study. MAIN OUTCOME MEASURES: Joint position sense was tested at the beginning, after 30 minutes uphill walking and after 30 minutes downhill walking on a treadmill (continuous protocol).

RESULTS: After downhill walking joint position sense was significantly worse than in the test at the beginning (p = 0.035, α = 0.05). After uphill walking no differences were observed in comparison with the test at the beginning (p = 0.172, α = 0.05) or in comparison with the test after downhill walking (p = 0.165, α = 0.05).

CONCLUSION: Downhill walking causes impairment in knee joint position sense. Considering these results, injury prevention protocols for hiking should focus on maintaining and improving knee proprioception during the descending phase.
