The purpose of this study was to investigate the physiological and anthropometric characteristics of junior volleyball players competing at the elite, semi-elite, and novice levels and to establish performance standards for these athletes. One hundred and fifty-three junior national (N = 14 males; N = 20 females), state (N = 16 males; N = 42 females), and novice (N = 27 males; N = 34 females) v...

Knee strength ratios are related to the movement patterns, sport-specific training and knee injuries in athletes. The purpose of this study was to determine the ratios in the concentric isokinetic strength of the hamstrings and quadriceps and the isometric strength of the knee extensors. In female basketball players (n = 14) and female volleyball players (n = 12) were evaluated: the hamstrings ...

OBJECTIVE The causal mechanism of the chronic sports injury patellar tendinopathy is not well understood. The aim of the present study was to compare ankle and knee joint dynamics during the performance of the volleyball spike jump between healthy volleyball players (n = 8) and asymptomatic volleyball players with previous patellar tendinopathy (n = 7). DESIGN Cross-sectional. METHODS Inver...

STUDY DESIGN Retrospective comparative study using radiographs and clinical findings. PURPOSE To test the hypothesis that asymmetric loading of immature spines in young athletes initiates scoliosis. OVERVIEW OF LITERATURE Scoliosis in athletes has been reported in the literature, but its causative factors have not been investigated. METHODS We compared the incidence, type and magnitude of...

Volleyball was created in 1895 by William Morgan. Women started to play it only in 1928. In 1916, volleyball gets to Brazil, brought by the Youth Men Christian Association, and in 1944 the First Brazilian Championship was held1. Volleyball is a sport that alternates aerobic and anaerobic activity, thus requiring muscular strength and power capability. The athlete must possess flexibility, stren...

Few studies directly compare the various fitness components of collegiate dancers and athletes in acknowledged sports. The limited studies that do exist fail to consider certain variables or to assess multiple fitness components. The purpose of this study was to provide a more comprehensive comparison of collegiate dancers and collegiate volleyball and softball players. We used multiple fitness...

The purpose of the study was to gain a deeper insight into the instructional process in youth volleyball training. A mixed method design, combining systematic observation and interview procedures, was used to examine both the nature and the content of the information provided by coaches during the instructional process. Twenty-eight young volleyball coaches, who coached amateur teams in a club ...

The objective of this study was to compare anthropometric variables (body weight, height, and percent body fat) and plantarflexion and dorsiflexion range of motion (ROM) between three different groups of women: classical ballet dancers (n=14), volleyball players (n=22) and physically active subjects (n=13). The assumption was that different functional requirements should produce differences in ...

We examined the association of R577X polymorphism (rs1815739) in the α-actinin-3 (ACTN3) gene with "explosive" leg muscle power performance in a group of male and female elite volleyball players (n=66, 31 men, 35 women) and in a group of non-athletic male and female young adults (n=334, 243 men, 91 women). We assessed power performance by means of the vertical squat and counter-movement jump te...
