The suprascapular nerve originates from the upper trunk of the brachial plexus or less frequently from the root of C5. It runs a short way and crosses the suprascapular notch. It innervates the supraspinatus muscle and the acromioclavicular and glenohumeral joints. Then, it crosses the lateral edge of the spine of the scapula passing through the spinoglenoid notch, and innervates the infraspina...

To the authors’ knowledge this is first study to describe strength and conditioning (S&C) practices perspectives of volleyball coaches players. In total, 30 (mean age 34.47 ± 7.83 years coaching experience 19.57 8.28 years), players 22.03 4.43 playing 10.43 8.98 years) completed an online survey with six sections: (a) informed consent; (b) background information; (c) education, qualificatio...

Aim: Motor learning is considered a complex process, providing numerous investigations. Knowledge of Results (KR), kind extrinsic feedback, one the variables that are used for investigations on motor learning. There different ways to provide KR optimize The bandwidth these forms, being factor affects learning, however, specificity task needs be in investigation this theme. Thus, objective study...

The aim of the study was to identify motor structures in elite female volleyball players aged 14-17, and to assess the effect of these motor structures on their technical and situation efficiency. For this purpose, a battery of 12 motor tests as predictor variables, and a set of six technical elements and evaluation of performance quality as criterion variables were applied in a sample of 147 f...
