Validity of Gymnastics-Specific Assessment of Neuromuscular Function of Shoulder Flexor and Extensor Muscles to Predict Performance in Gymnastics Skills

“…Moreover, changes at the peripheral level (e.g., muscle hypertrophy, changes in musculotendinous stiffness, and muscle architecture) could also be a determining factor (9,12,30). These neural and muscular adaptations linked to the specificity of gymnastic training increase the NME which characterized the capacity of muscles to develop a torque (5,17,29).…”

“…Therefore, the NME is considered an important tool for evaluating muscle response and functional performance after training (7) which can help sport scientists and trainers to understand the underlying mechanisms of training adaptation. Previous studies (5,17,29) examining the neuromuscular function of different joints found differences in NME between gymnasts and nonathletes. For example, researchers have reported higher NME for female gymnasts compared with nonathletes regarding plantar flexion (17) and trunk flexion (5) and for male gymnasts compared with nonathletes regarding shoulder flexion or extension (29).…”

Effect of Pilates Mat Exercises on Neuromuscular Efficiency of the Multifidus and Internal Oblique Muscles in a Healthy Ballerina

“…31 NME may vary according to gender, pathology, and training, conditions that can affect an individual's neuromuscular adaptation. [32][33][34][35][36][37] The multifidus (MU) and internal oblique (IO) muscles, acting in cocontraction, stabilize the trunk and control the segmental movement of the spine, keeping it in a neutral position. [38][39] No studies have been found that investigate NME of the MU and IO in Pilates practitioners who are ballet dancers.…”

“…EMG signals were filtered (fourth order Butterworth) at frequencies ranging from 20 to 500 Hz and analyzed using the MATLAB® software version 2009 (MathWorks®, Natick, Massachusetts, USA). The flexion and extension torque values were separately divided by the EMG value obtained from the sum of both muscles, resulting in the NME values for IO and MU [32][33][34][35][36][37] where: NME = Torque flexion / EMG(IO right + IO left ) and NME = Torque extension / EMG(MU right + MU left ).…”
