Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults. 相似文献

The aim of the present study was to analyse the training load in wheelchair basketball small-sided games and determine the relationship between heart rate (HR)-based training load and perceived exertion (RPE)-based training load methods among small-sided games bouts. HR-based measurements of training load included Edwards’ training load and Stagno’s training impulses (TRIMPMOD) while RPE-based training load measurements included cardiopulmonary (session RPEres) and muscular (session RPEmus) values. Data were collected from 12 wheelchair basketball players during five consecutive weeks. The total load for the small-sided games sessions was 67.5 ± 6.7 and 55.3 ± 12.5 AU in HR-based training load (Edwards’ training load and TRIMPMOD), while the RPE-based training loads were 99.3 ± 26.9 (session RPEres) and 100.8 ± 31.2 AU (session RPEmus). Bout-to-bout analysis identified greater session RPEmus in the third [P < 0.05; effect size (ES) = 0.66, moderate] and fourth bouts (P < 0.05; ES = 0.64, moderate) than in the first bout, but other measures did not differ. Mean correlations indicated a trivial and small relationship among HR-based and RPE-based training loads. It is suggested that HR-based and RPE-based training loads provide different information, but these two methods could be complementary because one method could help us to understand the limitations of the other. 相似文献

There is a major debate in the scholarly literature on whether early vocalizations imitate the mother tongue (L1) and whether prosody is an emerging feature of intentional communication. This longitudinal study explores the combinatory patterns of gestures and vocalizations of four Basque children aged 0:7 to 1:1 in the protoconversational stage. A total of 1,043 communicative acts were labelled (noting the kind of communication, the eye contact and the type of gestures), in which a total of 581 vocalizations were pragmatically and acoustically codified (marking the length and tonal range). The results showed that before they produce their first words, the children show a predominant pattern, tending to combine the deictic gestures with eye contact with the interlocutor. Furthermore, the children are capable of choosing specific prosodic signals — such as length and tonal range — to expression the intentionality of their vocalizations. This suggests that some prosodic features work as procedural antecedents in the process of constructing oral compositions. 相似文献

ABSTRACTThe aim of this study was to define and categorise different styles of play in elite soccer and associated performance indicators by using factor analysis. Furthermore, the observed teams were categorised using all factor scores. Data were collected from 97 matches from the Spanish La Liga and the English Premier League from the seasons 2006–2007 and 2010–2011 using the Amisco® system. A total of 19 performance indicators, 14 describing aspects of attacking play and five describing aspects of defensive play, were included in the factor analysis. Six factors, representing 12 different styles of play (eight attacking and four defensive), had eigenvalues greater than 1 and explained 87.54% of the total variance. Direct and possession styles of play, defined by factor 1, were the most apparent styles. Factor analysis used the performance indicators to cluster each team’s style of play. Findings showed that a team’s style of play was defined by specific performance indicators and, consequently, teams can be classified to create a playing style profile. For practical implications, playing styles profiling can be used to compare different teams and prepare for opponents in competition. Moreover, teams could use specific training drills directed to improve their styles of play. 相似文献

ABSTRACTThis study aimed to compare the goodness of fit and the reliability of different regression models for fitting the force-velocity relationship (FV) of bench press (BP) and squat (SQ). Additionally, the reliability of the position on FV of the velocity (V1RM) and the force performed with the 1RM (F1RM) was explored. Nine rugby players and 12 judokas participated in this study. The FV of BP and SQ were obtained twice by a protocol performed until the 1RM. Individual FV were fitted by linear (LM), quadratic polynomial (PM), and exponential models (EM). Adjusted coefficients of determination of LM and PM (medians higher than 0.919) were higher than for EM. The reliability was higher for LM in comparison with PM. The reliability of V1RM was not acceptable (CV% = 19 and 18% for BP and SQ). High reliability was observed for F1RM (CV% = 3 and 2% for BP and SQ) and for the ratio between F1RM and the force-axis intercept of FV (CV% = 2 and 4% for BP and SQ). The reliability of the relative values of F1RM around 92 and 87% of F0 for BP and SQ suggests the use of these values for monitoring resistance training programmes. 相似文献

Education during World War I has been a relatively unexplored field of research, especially in the case of countries with a neutral stance in that war. The Netherlands is one such country. This article argues that even though the Netherlands was politically neutral, it was and considered itself a part of western civilisation and shared in the experience of a cultural or existential crisis that came over Europe as a consequence of the war. This crisis also caused Dutch pedagogues to reflect on the war. Leading Dutch pedagogues wrote in their journals how education had to be changed in order to prevent a future war or to preserve moral values in their country, which was not (yet) part of the warfare. To characterise this effort, we introduce the concept of cultural mobilisation, following recent developments in the historiography of the cultural dimensions of the Great War. Based on an in-depth analysis of Dutch pedagogical journals, ranging from Protestant, Catholic and socialist to humanist and anarchistic world views, we focus on three pedagogical debates that were influenced by the Great War. The first debate focuses on peace education and shows how pedagogues rejected the war pedagogy of their German colleagues in particular and advised teachers to pass on a peace-loving message to their pupils. The second debate focuses on the reception of Montessori education and the third on Foerster’s and Kerschensteiner’s social pedagogy, both in light of the desire of pedagogues to improve moral education in the school. 相似文献
