The effect of hiking poles on oxygen uptake, perceived exertion and mood state during a one hour uphill walk

This study assessed changes in oxygen uptake, perceived exertion and mood state during a one hour uphill walk with and without hiking poles. Six males and one female with hill walking experience (Mean age ± SD = 24.2 ± 4.7 years) completed two, one hour walking trials in a counterbalanced order (one with hiking poles, one without) and separated by 48-72 hours, on a treadmill inclined at 5%. Treadmill velocity was established a priori such that the subject's heart rate was between 55-65% of their maximum, using the Karvonen formula. Ratings of perceived exertion (RPE) were collected at 10-minute intervals. Oxygen uptake (ml·kg^-1·min^-1) was assessed continuously and averaged over 10-minute periods and mood state was assessed pre and post each condition. Results indicated that oxygen uptake was significantly greater (P = 0.001) during the poles condition compared to the no poles condition. RPE was not significantly different across conditions (P = 0.07). In addition, there was a significantly greater change in mood state (pre to post) in the no poles condition compared to the poles condition (P = 0.03). These results indicate that the use of hiking poles may have a psychological benefit to hill walkers despite increased physiological load associated with their use.
