AB  - Milosis, DC. Validity of gymnastics-specific assessment of neuromuscular function 
      of shoulder flexor and extensor muscles to predict performance in gymnastics 
      skills. J Strength Cond Res 37(3): 652-660, 2023-This study examined the 
      relationships between gymnastics-specific laboratory measurements of 
      neuromuscular function of the shoulder flexor and extensor muscles and 
      performance in specific gymnastics skills. Fifteen highly competitive male 
      gymnasts and 18 male students (age 20.41 +/- 2.51 years, body mass 69.7 +/- 7.07 kg; 
      mean +/- SD ) participated voluntarily. The electromyogram (EMG) was used to assess 
      muscle activation of 3 flexor and 3 extensor shoulder muscles during isometric 
      (45, 90, and 135 degrees ) and isokinetic (concentric and eccentric 60, 180, and 300 degrees /s) 
      flexion-extension of the shoulder. Peak torque (PT), neuromuscular efficiency 
      (NME: torque to EMG ratio), and antagonist coactivation index (CI) were 
      evaluated. Furthermore, performance in specific gymnastics skills was evaluated. 
      The results supported the ecological validity of the measurements. Specifically, 
      significant correlations emerged between the shoulders' neuromuscular function 
      parameters and the performance in the gymnastics skills (PT: r = 0.798, p < 
      0.001, NME: r = 0.576, p < 0.001, CI: r = -0.351, p < 0.05). In addition, 
      according to the results of the regression analysis, neuromuscular function of 
      the shoulder flexor and extensor muscles predicted gymnastics performance. 
      Specifically, the model that was produced significantly predicted the dependent 
      variable (performance in specific gymnastics skills) in all steps and explained a 
      total variance of 64.4% ( p < 0.001). Based on beta coefficients, PT had the 
      higher contribution to the prediction of performance. The insight gained on these 
      relationships could help coaches to plan the training of their gymnasts and to 
      monitor the longitudinal changes in neuromuscular function of shoulder muscles 
      induced by training more effectively.
