Bottom Line: Female skaters demonstrated higher muscle activities in tibialis anterior, vastus lateralis, vastus medialis and gluteus maximus during the landing phase of the triple Mapes, when compared to their male counterparts.The results obtained in this study should be considered when planning training programs with specific exercises that closely resemble the roller figure skating jumps.This may be important for the success of elite skaters in competitions.

ABSTRACT
This study aimed to describe the neuromuscular activity of elite athletes who performed various roller figure skating jumps, to determine whether the muscle activation is greater during jumps with more rotations and in which phase the muscles are more active. This study also aimed to analyze if there is any difference in the muscle activity pattern between female and male skaters. Four elite skaters were evaluated, and each participated in two experimental sessions. During the first session, anthropometric data were collected, and the consent forms were signed. For the second session, neuromuscular data were collected during jumps, which were performed with skates at a rink. The following four roller figure skating jumps were evaluated: single Axel, double Axel, double Mapes and triple Mapes. The neuromuscular activity of the following seven muscles was obtained with an electromyograph which was fixed to the waist of each skater with a strap: biceps femoris, lateral gastrocnemius, tibialis anterior, rectus femoris, vastus lateralis, vastus medialis and gluteus maximus. The signal was transmitted wirelessly to a laptop. During the roller figure skating jumps, the lateral gastrocnemius, rectus femoris, vastus lateralis, biceps femoris and gluteus maximus, showed more activation during the jumps with more rotations, and the activation mainly occurred during the propulsion and flight phases. Female skaters demonstrated higher muscle activities in tibialis anterior, vastus lateralis, vastus medialis and gluteus maximus during the landing phase of the triple Mapes, when compared to their male counterparts. The results obtained in this study should be considered when planning training programs with specific exercises that closely resemble the roller figure skating jumps. This may be important for the success of elite skaters in competitions.

f1-jhk-41-23: Single Axel (A); double Axel (B); double Mapes (C) and triple Mapes (D) in each phase: preparation, take-off, flight and landing

Mentions: The neuromuscular activity of the rectus femoris, vastus lateralis, vastus medialis, gluteus maximus, gastrocnemius lateralis, tibialis anterior and the short head of the biceps femoris was obtained from the left leg of skaters while they performed the following jumps: single Axel, double Axel, double Mapes and triple Mapes (Figure 1). The Mapes jump in roller figure skating is similar to the toe loop jump, which is performed in ice figure skating. The left leg for both Axel and Mapes jumps is the take-off leg. However, the Axel jump starts when the left leg is in contact with the ground, and the Mapes jump starts while the skater has his or her body weight over the right leg. During the preparation of the Mapes jump the skater transfers his or her body weight from the right leg to the left leg, pressing the toe pick against the floor, which allows the skater to perform the take-off phase from the left leg.
