Opis:
The aim of this study was to determine the technical performance profile of service reception with regard to execution and efficacy level according to level of competition in women’s volleyball. The sample of the study was composed of a total of 6,311 game phases from 187 sets in 48 matches played during season 2005–2006 by the following divisions: under-14, under-16, under-18, 2nd national senior division, 1st national senior division, and international senior division. The design of the study was a descriptive and inter- and intra-group correlational one. The variables studied included level of competition, technique used to serve, technique used to receive, zone where the reception was executed, and efficacy of reception. The results indicated that at higher levels of competition: a) there is higher efficacy in reception; b) number of errors decreases; and c) proportion of receptions that allow one or more attacking options for the receiving team increases. As level of competition increases, the effect of service on reception decreases, and receiving zones are more diverse. This study establishes the technical and tactical service-reception profiles in women’s volleyball, compares them, and establishes the dependence between variables to understand how the action changes throughout the levels of competition.

Opis:
The goal of this study was to establish technical and tactical performance goals for elite male volleyball players (Spanish first division). This paper is the result of scientific collaboration between volleyball coaches and researchers. The process of establishing the goals and the reference values of the performance goals was: 1) conceptual analysis, establishing the criteria for the analysis of players’ and teams’ performance (researchers and coaches); 2) mathematical analysis, data collection and data analysis of the possible performance goals; and 3) practical analysis, establishing the performance goals according to their usefulness and applicability following the SMART principle. Seven performance goals were established to evaluate the technical-tactical actions of the players in training and in competition. Protocols utilized can be used as references of how to calculate the technical and tactical performance goals in sport.

Opis:
Objectives This study aimed to evaluate cytogenetic damage in the buccal mucosa of non-exposed subjects (N = 33) and insecticide-exposed fumigators (N = 31) in the urban area of Cali, Colombia. Material and Methods Through a questionnaire sociodemographic data, anthropometric measurements, state of health, and lifestyle were collected. Buccal micronucleus cytome (BMCyt) assay was using for evaluate cytogenetic damage. Results The study showed that all fumigators used adequate personal protective equipment (PPE) and had low alcohol consumption. The authors did not find significant differences in BMCyt biomarkers between the groups (p > 0.05). Multivariate analysis showed a 13% increase in micronucleus (MN) frequency for every year of increasing age (OR = 1.13, p = 0.029), and higher MN with the decrease in daily fruit consumption (OR = 4.71, p = 0.084), without statistical significance. Conclusions The results between groups could be related to healthy habits and PPE use among the subjects.
