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...

In the present study, differences in visuospatial attention lateralization were evaluated in athletes engaged in open-compared to closed-skill sports and sedentary nonathletes. 23 volleyball players (open skill; Italian national level and regional level), 10 rowers (closed skill, Italian national level), and 23 sedentary participants responded to a computerized line-length judgment task. Five l...
The purpose of this research project was to evaluate the methodology of an iso-inertial force-velocity assessment utilizing a range of loads and a group of high-performance athletes. A total of 26 subjects (19.8 +/- 2.6 years, 196.3 +/- 9.6 cm, 88.6 +/- 8.9 kg) participated in this study. Interday reliability of various force-time measures obtained during the performance of countermovement jump...
