Abstract
Investigations into ventilatory, metabolic, and hematological changes with altitude training have been completed; however, there is a lack of research exploring potential gait kinematic changes after altitude training, despite a common complaint among athletes being a lack of leg “turnover” upon return from altitude training.
PURPOSE:
To determine if select kinematic variables changed in a group of elite distance runners after 4wks of altitude training.
METHODS:
Six elite male distance runners completed a 28d altitude training intervention in Flagstaff, Arizona (2150m), following a modified “live high – train low” model, wherein higher intensity runs were performed at lower altitudes (945-1150m) and low-intensity sessions were completed at higher altitudes (1950-2850m). Gait parameters were measured 2-9d prior to departure to altitude and 1-2d after returning to sea-level at running speeds from 300 to 360 m·min-1.
RESULTS:
No differences were found in ground contact time, swing time, stride length, or stride frequency after altitude training (p>0.05).
CONCLUSIONS:
Running mechanics are not affected by chronic altitude training in elite distance runners. The data suggest that either: a) chronic training at altitude truly has no effect on running mechanics, or b) completing the live high – train low model of altitude training, where higher velocity workouts are completed at lower elevations, mitigates any negative mechanical adaptations that may be associated with chronic training at slower speeds.
