The purpose of this study was to examine the effects of the telescope-style running poles on the lo wer-extremity running mechanics of the subjects with chronic knee problems. Ten male recreational runners (age = 55.2 ± 9.0 yr) with chronic knee problems participated in this study. Each subject was individually fitted with a pair of specially-designed telescope-style running poles. The pole-running trials of the subjects were compared with their normal running trials after a 4-week familiarization period. The maximum knee flexion angle during the swing phase significantly decreased by 12.2° due to the use of the running poles. The ground reaction force data revealed a consistent trend of decrease with significant decreases in the peak vertical propulsive force (11.4%) and the vertical impulse (11.4%) due to the use of the poles. It was concluded that (a) the telescope-style running poles significantly altered the lower-extremity kinematics by decreasing the knee flexion during the swing phase, and (b) the running poles generally reduced the foot -ground interaction and provided a source of propulsion during the push-off phase of the running gait.

NORDIC WALKING BRASIL

A Caminhada Nórdica foi primeiramente desenvolvida como metodologia de treinamento de verãos para esquiadores. Foi à partir daí transformada em um exercício de Fitness com equipamento específico.
