There is an evident lack of studies on the effectiveness of plyometricand skill-based-conditioning in volleyball. This study aimed to evaluate effects of 12-week plyometricand volleyball-skill-based training on specific conditioning abilities in female volleyball players. The sample included 41 high-level female volleyball players (21.8 ± 2.1 years of age; 1.76 ± 0.06 cm; 60.8 ± 7.0 kg), who pa...

The survey on the willpower of Chinese professional volleyball players shows that Chinese female volleyball players are more tenacious than male players, while male players are better in self-control. Willpower of volleyball players is independent with training duration and individual skill level of the players. The ace spiker is more clear in target than the setter and auxiliary setter; the se...

Four volleyball teams (N-48) filled the Revised Competitive State Anxiety Inventory – 2 (CSAI-2R) by Cox, Martens and Russel (2003), used in measuring somatic and cognitive anxiety and self-confidence. The questionnaire was filled immediately before the teams played their first match at the European junior championship, with the aim of determining does the pre-competitive anxiety influence the ...

OBJECTIVES The purpose of this study was to determine the effect of sports participation on cortical bone in the tibia. METHODS 53 female collegiate athletes (25 cross-country, 16 soccer, and 12 volleyball) and 20 inactive controls had the left distal 20% tibia scanned by pQCT. Cortical volumetric BMD (vBMD) was measured within the cortical shell at the anterior, posterior, medial, and latera...

OBJECTIVE Abnormal imaging in the patellar tendon reveals pathology that is often associated with knee pain. Anthropometric measures of body size and mass, such as height, weight and waist-to-hip ratio (WHR), have been individually associated with abnormal imaging. The aim of this study was to investigate the anthropometric factors that have the strongest relationship with abnormal imaging in v...

The aim of the study was to investigate whether genetic variants in VEGF and KDR genes can be correlated with susceptibility of tendinopathy in volleyball athletes. This study was conducted at the Brazilian Volleyball Federation, and comprised 179 volleyball athletes: 88 had a confirmed diagnosis of tendinopathy (cases), whereas 91 had no evidence of the disease (controls). The VEGF (-2578C>A, ...

This study evaluated force and velocity parameters of vertical jump performance in countermovement jump (CMJ) and squat jump (SJ) and compared results for sprint runners and volleyball players. Twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) performed CMJ and SJ on a force platform. The following variables were analyzed: jump perfor...

The aim of the study was to identify morphological structures of young female volleyball players according to age, and to assess the impact of these morphological structures on technical and situation efficacy. A set of 13 morphological measures as predictor variables, a set of 6 technique elements, and assessment of performance quality as criterion variables were employed in a sample of 246 fe...

Volleyball players performed numerous repetitions of spike actions, which uses and requires strong and explosive force, and control of the muscles of the shoulder, lower back, and legs. Muscle imbalance is one of the main causes of sport injuries. The purpose of this study was to assess isokinetic muscle functions in male volleyball players. We thus aim to accurately evaluate their muscle funct...

OBJECTIVE High voice users (individuals who demonstrate excessive or loud vocal use) are at risk for developing voice disorders. The objective of this study was to examine, both acoustically and perceptually, vocal changes in healthy speakers after an acute period of high voice use. METHODS Members of a university women's volleyball team (n = 12) were recorded a week before (pre) and week aft...
