The purpose of this study was to determine and to compare characteristics of the lower limb extension musculature in Chilean indoor and beach volleyball players and the muscular contribution during the CMJ. The sample was composed by 13 subjects belonging to the Chilean elite beach and indoor volleyball. The subjects performed 3 CMJ jumps for average determination of the height of the jump, ecc...

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...

BACKGROUND The VISA-P questionnaire evaluates severity of symptoms, knee function and ability to play sports in athletes with patellar tendinopathy. This English-language self-administered brief patient outcome score was developed in Australia to monitor rehabilitation and to evaluate outcome of clinical studies. Aim of this study was to translate the questionnaire into Dutch and to study the r...

INTRODUCTION Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From 1992 th...

The aim of this study was to examine the relationship between the intensity and direction of competitive state anxiety, self-confidence and performance in basketball and volleyball players prior to different matches. Male basketball (n=12) and volleyball players (n=12) completed a modified version of the Competitive State Anxiety Inventory-2 (CSAI-2) prior to 11 different matches, and a total o...

During the 1993-1994 volleyball season, injuries to players in the two Danish elite divisions were registered by means of a questionnaire survey. Eighty per cent of the players returned the questionnaire. A total of 70 female players reported 79 injuries and 67 male players reported 98 injuries, representing an overall incidence of 3.8 injuries per player per 1000 volleyball hours played. The i...

Volleyball has become an extremely popular participation sport worldwide. Fortunately, the incidence of serious injury is relatively low. The sport-specific activity most commonly associated with injury is blocking. Ankle sprains are the most common acute injury. Recurrent sprains may be less likely to occur if an ankle orthosis is worn. Patellar tendinitis represents the most common overuse in...

T eam volleyball is an Olympic sport played professionally in many countries around the world. Despite the increasing professionalization of coaches and athletes, there is little research data concerning performance in professional volleyball players. Two major reasons for this are suggested. Some coaches adopt traditional methodologies in resistance training (RT) programs for team volleyball, ...

We examined ninety-six top-level volleyball players from eight teams that competed during the 1985 European Championships, and twelve players were found to have asymptomatic isolated paralysis of the infraspinatus of the dominant side. Three players were studied with electromyography and Cybex-II isokinetic dynamometry. The results revealed denervation of the infraspinatus and approximately a 2...

The aim of this work was to analyze the postural sway of volleyball players in bipedal quiet stance. The center of pressure (CoP) was measured in 46 athletes and 42 non-athlete controls. Each subject was tested in 10 different conditions, 5 with their eyes open and 5 with their eyes closed. Volleyball players showed greater CoP ellipses, suggesting a different model of sensory integration in th...
