Practice task design in team sports: Representativeness enhanced by increasing opportunities for action

Abstract This study investigated effects of manipulating the number of action possibilities in a futsal passing task to understand the representativeness of practice tasks designs. Eight male senior futsal players performed a passing task in which uncertainty on passing direction for the player in possession of the ball was increased in four conditions and compared with passing data from a competitive match. Performance during a passing task and competitive futsal performance was compared using ball speed and passing accuracy data. Ball speed data were analysed by approximate entropy (ApEn) to capture their regularity in each of the four conditions and during competitive performance. Significantly high levels of regularity were observed in predetermined passes in comparison with emergent passes (i.e., passes with high number of possibilities for action). Similar results for ball speed regularity were observed between practice tasks with a high number of possibilities for action (i.e., emergent passes) and competitive performance. Similar results were observed for passing accuracy in practice tasks with a high number of possibilities for action compared to competitive performance. Increases in the number of action possibilities during practice improved action fidelity of tasks in relation to competitive performance.     

Movement behaviors and their association with depressive symptoms in Brazilian adolescents: A cross-sectional study

Background:Physical activity,sleep,and sedentary behaviors compose 24-h movement behaviors and have been independently associated with depressive symptoms.However,it is not clear whether it is the movement behavior itself or other contextual factors that are related to depressive symptoms.The objective of the present study was to examine the associations between self-reported and accelerometer-measured movement behaviors and depressive symptoms in adolescents.Methods:Cross-sectional data from 610 adolescents(14-18 years old)were used.Adolescents answered questions from the Center for Epidemiological Studies Depression scale and reported time spent watching videos,playing videogames,using social media,time spent in various physical activities,and daytime sleepiness.Wrist-worn accelerometers were used to measure sleep duration,sleep efficiency,sedentary time,and physical activity.Mixed-effects logistic regressions were used.Results:Almost half of the adolescents(48%)were classified as being at high risk for depression(score≥20).No significant associations were found between depressive symptoms and accelerometer-measured movement behaviors,self-reported non-sport physical activity,watching videos,and playing videogames.However,higher levels of self-reported total physical activity(odd ratio(OR)=0.92,95%confidence interval(95%CI):0.86-0.98)and volume of sports(OR=0.88,95%CI:0.79-0.97),in minutes,were associated with a lower risk of depression,while using social media for either 2.0-3.9 h/day(OR=1.77,95%CI:1.58-2.70)or>3.9 h/day(OR=1.67,95%CI:1.10-2.54),as well as higher levels of daytime sleepiness(OR=1.17,95%CI:1.12-1.22),were associated with a higher risk of depression.Conclusion:What adolescents do when they are active or sedentary may be more important than the time spent in the movement behaviors because it relates to depressive symptoms.Targeting daytime sleepiness,promoting sports,and limiting social media use may benefit adolescents.     

Intergenerational preschool experiences and the young child: Potential benefits to development

We conducted an exploratory study evaluating the potential impact of intergenerational programming (IG) on children's socio-emotional development, behavior, school performance, and attitudes and behavior toward older adults. Children currently in kindergarten through second grade (age range: 6–8 years old) who previously attended one of two preschools of comparably high quality and serving families of similar demographic profiles were compared 1–3 years after graduating from their respective programs. One program offered intergenerational (IG) programming while the other was a traditional single-generation program (SG). Face-to-face interviews were conducted with the child and one of his/her parents in their home. In addition, a mail survey was sent to the child's school teacher. The study explored whether children exposed to IG had differential outcomes on specific measures as compared to children who attended the SG program. Results showed that children from the IG program had higher levels of social acceptance, a greater willingness to help and greater empathy for older people, slightly more positive attitudes, and better able to self-regulate their behavior than children from the SG program. Although limited by the lack of a pre–post experimental design, these results provide initial evidence that an IG program can offer additional benefits to children's development whose impact can last into the their early school age years.     

Cooperative methods and self-regulated strategies development for argumentative writing

The authors analyze the efficacy of a cooperative method associated with self-regulated strategy development (SRSD) for argumentative writing compared with a SRSD single approach. Seven teachers and 230 ninth-grade students from three middle schools participated in the present study in which teachers were part of a practice-based professional development program. Schools were assigned either to the experimental group or to the comparison group. Over a three-month period, all students were taught SRSD strategies. After this period, students from the experimental group participated in a cooperative setting, whereas the comparison group followed the SRSD only. The results indicated that students in the experimental group made statistically significant greater gains in structural argumentative elements and in the quality of writing texts immediately after the intervention and one month later. Thus, the study provides evidence for the benefits of adding a cooperative setting to SRSD in implementing argumentative writing skills.     

High-volume resistance training reduces postprandial lipaemia in postmenopausal women

The aim of this study was to compare the effects of 11 weeks of low-volume resistance training (LVRT) and high-volume resistance training (HVRT) on muscle strength, muscle thickness (MT), and postprandial lipaemia (PPL) in postmenopausal women. Thirty-six healthy and untrained postmenopausal women (age, 58.9 ± 5.8 years; 68.6 ± 10.3 kg; and BMI, 26.9 ± 4.8 kg · m^?2) participated in resistance training 3× per week for 11 weeks (HVRT = 12; LVRT = 13; and control group = 11). Biochemical variables, both pretraining and post-training, were evaluated 16 h after the administration of an oral fat tolerance test (OFTT) and metabolic variable during [energy expenditure (EE)] and after training session [excess postexercise oxygen consumption (EPOC)]. Muscle strength (1 RM) and MT were also calculated, and no significant differences were observed between the groups for PPL (mmol · L^?1 per 5 h) as measured by glucose, high-density lipoprotein, low-density lipoprotein, and total cholesterol. EE total (EE + EPOC; 6.12 ± 1.21 MJ vs. 2.26 ± 0.85 MJ), resting fat oxidation (5.52 ± 1.69 g · h^?1 vs. 4.11 ± 1.12 g · h^?1); MT (vastus medialis, 21.4 ± 1.8 mm vs. 18.4 ± 1.2 mm and vastus lateralis 22.3 ± 1.2 mm vs. 20.8 ± 1.3 mm); triacylglycerol (TAG) 0, 1, 2, 4; and 5 h after OFTT, TAG area under the curve (AUC) (5.79 ± 0.42 vs. 7.78 ± 0.68), and incremental AUC (?46.21 ± 14.42% vs. 7.78 ± 4.68%) were all significantly different post-training for HVRT versus LVRT, respectively (P < 0.05). The results of this investigation suggest that HVRT reduces PPL in postmenopausal women.

“We Share the Same Biology…” Cultivating Cross-Cultural Empathy and Global Ethics Through Multilingualism

The “language-culture tesseract” hypothesized in the September 2010 issue of Mind, Brain, and Education suggests successive links between non-native language (NNL) acquisition, the development of cross-cultural empathy, and prosocial global ethics. Invoking Goethe's (1833/1999) aphorism, “those who do not know other languages know nothing of their own,” it was argued that becoming plurilingual constitutes an essential step toward metalinguistic and metacultural awareness; and that “what is true of water for a fish is also true of the mother tongue and of the native culture for a human being.” In this article, we would like to elaborate on that argument and submit to the MBE community the idea of applying the developing understanding of empathy in the brain toward the design of new approaches to NNL education that maximize its potential to cultivate a positive local–global dialectic in students.     

Expert judgements and the demand for novels in Flanders

This paper analyses the effect of literary prizes and nominations on the subsequent market success using a panel dataset of Dutch-language titles from January 2003 to June 2005. The analysis indicates winning a prize generally has a positive effect on the ensuing sales, whereas nominations do not generate additional sales. The precise effect differs depending on the particular prize. Winning a “home” debut prize has a significant positive effect on sales, and, to a lesser extent, “established” literary prizes have a significant positive effect on the sales of the winning title, but winning a debut prize in the Netherlands, the neighbouring country, has no effect on sales in Belgium.
