This study analysed the validity and reliability of a new optoelectronic device (Velowin) for the measurement of vertical displacement and velocity as well as to estimate force and mechanical power. Eleven trained males with Mean (SD) age = 27.4 (4.8) years, completed an incremental squat exercise test with 5 different loads (<30–90% of their 1?repetition maximum) while displacement and vertical velocity of the barbell were simultaneously measured using an integrated 3D system (3D motion capture system + force platform) and Velowin. Substantial to almost perfect correlation (concordance correlation coefficient = 0.75–0.96), root mean square error as coefficient of variation ±90% confidence interval ≤10% and good to excellent intraclass correlation coefficient = 0.84–0.99 were determined for all the variables. Passing and Bablock regression methods revealed no differences for average velocity. However, significant but consistent bias were determined for average or peak force and power while systematic and not proportional bias was found for displacement. In conclusion, Velowin, in holds of some potential advantages over traditionally used accelerometer or linear transducers, represents a valid and reliable alternative to monitor vertical displacement and velocity as well as to estimate average force and mechanical power during the squat exercise. 相似文献

Variability analysis has been used to understand how competitive constraints shape different behaviours in team sports. In this study, we analysed and compared variability of tactical performance indices in players within complex I at two different competitive levels in volleyball. We also examined whether variability was influenced by set type and period. Eight matches from the 2012 Olympics competition and from the Portuguese national league in the 2014–2015 season were analysed (1496 rallies). Variability of setting conditions, attack zone, attack tempo and block opposition was assessed using Shannon entropy measures. Magnitude-based inferences were used to analyse the practical significance of compared values of selected variables. Results showed differences between elite and national teams for all variables, which were co-adapted to the competitive constraints of set type and set periods. Elite teams exploited system stability in setting conditions and block opposition, but greater unpredictability in zone and tempo of attack. These findings suggest that uncertainty in attacking actions was a key factor that could only be achieved with greater performance stability in other game actions. Data suggested how coaches could help setters develop the capacity to play at faster tempos, diversifying attack zones, especially at critical moments in competition. 相似文献

Development is concerned with the biological security and well-being of people, and so all development theory and practice are biopolitical in a fundamental sense. The paper argues that for development to be made meaningful, it needs to legitimate itself through the production of healthy bodies, which can be realized through food security, immunization drives, and housing schemes among others. A postcolonial democratic state like India makes an effort to protect its people from hunger and draws its legitimacy from the same. Yet at the same time, the supposed development of the nation implies a concurrent elision of the weak and the vulnerable. Drawing upon India’s experiment with food security, public distribution systems, and other similar schemes, the paper advances an idea of development that is not only inherently biopolitical, but also a compromise between the commitment to protect people from hunger and the need for working around international agencies. While doing so, the paper borrows from the theoretical vocabulary of Foucault, Agamben, and others to historicize the modernist idea of protecting citizens as well as the reality of deaths from hunger and development-induced displacement. 相似文献

Method Engineering (ME)1facilitates the use of situation-specific methods for information systems development (ISD). We have studied the educational effects of ME by monitoring the process of students experiencing ME. First we describe the course of the Open University of The Netherlands that introduces ME. We then elaborate on the specifics of ME and present results related to the learning process of a population of over 70 students having professional experience in ISD already. In this paper we concentrate on some entry and exit level characteristics of the students and the feasibility and reproducibility of ME in a practical case study done by the students. 相似文献
