This study investigated (I) differences in muscle activation of both legs between the straight and the curve and (II) changes in muscle activities during a 1000-m time trial and their relationship to the change in skating velocity in nine young short-track speed skaters. We recorded skating times and EMG data from different leg muscles during maximum effort skating trials on the straight and in the curve as well as during a 1000-m time trial. THE RESULTS
are: (I) muscle activation differs between the straight and the curves and between legs, i.e. average activities of selected muscles of the right leg were significantly higher during skating through the curves compared to the straights. This could not be observed for the left leg. (II) The reduction in speed during the 1000-m time trial highly correlates with the decrease in the muscle activity of both the tibialis anterior and rectus femoris of the right leg. Muscle recruitment is different in relation to the lap section (straight vs. curve) and the leg (right leg vs. left leg). The decreased muscle activities of the tibialis anterior and rectus femoris of the right leg show the highest relationships with the reduction in skating speed during the 1000-m time trial.
