Quantifying the offensive sequences that result in goals in elite futsal matches

The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense “transitions” (n = 45) and the start of offensive plays due to the rules of the game (n = 45) were the most common type of sequences that resulted in goals compared to other patterns of play. The central offensive zonal areas were the most common for shots on goal, with 73% of all goals scored from these areas of the pitch compared to defensive and wide zones. The foot was the main part of the body involved in scoring (n = 114). T-pattern analysis of offensive sequences revealed regular patterns of play, which are common in goal scoring opportunities in futsal and are typical movement patterns in this sport. The data demonstrate common offensive sequences and movement patterns related to goals in elite futsal and this could provide important information for the development of physical and technical training drills that replicate important game situations.     

Remote ischaemic preconditioning shortens QT intervals during exercise in healthy subjects

The protective action of remote ischaemic preconditioning (RIPC) has been demonstrated in the context of surgical interventions in cardiology. Application of RIPC to sports performance has been proposed, but its effect on the electrocardiogram (ECG) during exercise remains unknown. This exploratory study aims to measure the changes in ventricular repolarization observed during exercise following RIPC in healthy subjects. In an experimental randomized crossover study, 17 subjects underwent two bouts of constant load exercise tests at 75% and 115% of gas exchange threshold (GET). Prior to exercise, they were allocated to either control or RIPC intervention with four cycles of 5?min of ischaemia followed by 5?min of reperfusion. ECG was continuously recorded during the protocol. QT and RR intervals were measured every 30?s (on an average tracing of the preceding 10?s). Although the time course of RR intervals did not differ between the two interventions (p?=?.56 at 75% GET and p?=?.74 at 115% GET), a significant shortening of QT intervals (measured from Q onset to T end) was observed during exercise (mean?±?standard deviation of RIPC vs. control: ?32?±?19?ms at 75% GET (p?p?p?p?相似文献   

Effects of the financial crisis on university choice by gender

This study analyses the university choices of male and female students in Italy over the 2003–2012 period and for two sub-periods before (2003–2008) and after (2009–2012) the 2008 financial crisis. The analysis is guided by human capital, signalling and preference theories and implemented through a competing destinations model that controls for the socio-economic features of both the region of origin and destination. The findings show that in the post-crisis period, males became more career-oriented in their university choices due to increasingly constrained and competitive labour markets. The constrained post-crisis labour markets led females to focus more on the educational experience than on future employability prospects. Our results suggest that the financial crisis maintained or even widened gendered social roles as they relate to university choices; specifically, males assumed an even greater career-centred family role, whereas females adopted more adaptive lifestyles that potentially place them at a disadvantage in the labour market and in society in years to come.     

Influence of the difficulty of the Matching Familiar Figures Test-20 on the assessment of reflection–impulsivity: An item analysis

This study is an item analysis of the Matching Familiar Figures Test-20. We examined error scores in the Matching Familiar Figures Test-20 to determine the influence of the difficulty of the test on the assessment of reflection–impulsivity. The sample included 700 participants aged between 6 and 12 years. The results obtained from the corrected item–total correlation showed moderate but significant values for the discrimination index in all age groups, although the lowest values were found in the 6-year-old group. The item difficulty data show that the test is quite difficult for 6-year-old participants and quite easy for 12-year-old participants, and more likely to show individual differences between these ages. The results suggest that the difficulty of the MFFT20 is appropriate for children between 6 and 12 years. However, because of some floor and ceiling effects, the results of this test for ages 6 and 12 should be interpreted very cautiously, especially for the 6-year-old group.     

Going places: exploring the impact of intra-sectoral mobility on research productivity and communication behaviors in Japanese academia

This study analyzes the impact of intra-sectoral mobility of academics on research productivity and R&D information exchange dynamics in Japan. The analysis shows intra-sectoral mobility impacting positively both research productivity and information exchange dynamics, but that this effect—except for information exchange with peers based abroad—has a threshold. This result highlights the importance of academic job mobility but also alerts for cases of “overloads of mobility,” leading us to argue for some degree of stability in academic careers, supported by policies fostering temporary international mobility spells. We also find that the role of foreign academics in the Japanese higher education is one of national and international gatekeepers being this role shaped by where the doctorate was obtained (Japan vs abroad). Japanese academics that have performed the doctorate abroad are also key international gatekeepers.
