From the data analysis, it was concluded that (a) the telescope-style running poles altered the lower-extremity running
kinetics by decreasing the knee flexion during the swing phase and increasing the maximum hip hyperextension, 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, decreasing the amount of force and impulse imposed upon the foot in subjects with chronic knee problems.
Lightweight adjustable trekking poles boasting a contour grip and slim profile. . These poles now feature the new duo-lock system. Unlike most locking mechanisms, this system utilizes two expanding sleeves that lock with a single turn. Combined with reinforced polymers, the duo-lock system greatly reduces the chances of the pole collapsing when weighted.
