Effects of a nonlinear pedagogy intervention programme on the emergent tactical behaviours of youth footballers

Purpose: This study analysed the effects of a training intervention programme using principles of Non-Linear Pedagogy (NLP) on the decision making (DM) and performance behaviours (P) of youth footballers.

Method: 19 footballers (U12 yrs) participated in 14 training sessions, spread over three phases: Pre-intervention, Intervention, Retention. The intervention was based on Small-Sided and Conditioned Games. We assessed progress during the intervention phase at two different points: intermediate and final. The GPET instrument was used to analyse the DM and P during the completion of 3208 passes in the intervention.

Results: Results shown significant improvements in the DM and P after the intermediate and final points of the acquisition phase. Moreover, significantly higher values were also obtained in both variables in the retention, compared to the pre-intervention phase.

Conclusion: Results indicated that the NLP intervention programme was effective in improving both aspects of team games performance in youth players, with effects consolidated over time.     

Significant life experiences and their relationship with the education of the scrutinizing gaze in the beauty ecologist César Manrique

The reality of the nature that we see can have multiple messages and meanings. Some of these are patent and continuously communicate with the individual, but others are hidden and are more difficult to unravel. A deep, contemplative and scrutinizing gaze is necessary to detect these messages. Educating this “new” way of seeing can help reinforce a person-nature bond that includes the aesthetic appreciation of beauty. This work shows the education of the gaze related to the artist César Manrique and the special bond that he established with the island of Lanzarote. He describes some key experiences, considered to be significant life experiences (SLEs), that revealed deep and secret messages to him and made him understand the true magnitude of the person-nature bond.     

The Engagement of Transnationals in Mexican University Classrooms: Points of Entry Toward Recognition Among Future English Teachers

For better or worse, English continues to expand as the commonly shared lingua franca throughout the world. With an increasing movement of transnational students—armed with English and flowing across borders—three university professors discuss their pedagogies and ways of knowing as they engage transnational students inside Mexican university classrooms for future teachers of English. Situated at an interior Mexican public university, each of them explores their unique positioning and the ways they taught transnational students. One is a transnational Mexican-American instructor; another is a researcher of transnationalism historically based in the U.S., and the other co-author is a Mexican national who learned English as a second language and has witnessed the rapidly changing population of students in the interior of Mexico. Toward the aim of improving the way transnationals access and experience formal education, they provide recommendations for improving pedagogy and expanding research.     

Search for autonomy in motor task learning in physical education university students

The study focused on discovering the influence that an autonomous motor task learning programme had on the improvement of perceived competence, intrinsic regulation, incremental belief and motivational orientations. The study was performed with two groups of participants (n = 22 and n = 20) aged between 19 and 35 years. The instruments used were the incremental factor of the Conceptions of the Nature of Athletic Ability Questionnaire (CNAAQ-2), the Goal Orientation in Exercise Scale (GOES), the intrinsic regulation factor of the Behavioural Regulation in Exercise Questionnaire (BREQ-2), the perceived autonomy factor of the autonomy measurement scale (EMA) and the perceived competence factor of the Motives for Physical Activity Measure Revised Scale (MPAM-R). The questionnaires were handed out over 3 months in a weekly session with pre-test and post-test. The results showed that the use of an autonomy-based teaching programme increased perceived competence, intrinsic motivation, incremental ability belief and task-involving motivational orientation.     

The path to information in the public domain: Official publications in Spain

Official publications are aimed towards editing and spreading the messages created by governments and other bodies of the public domain. At the beginning, the aim of this activity is twofold: on the one hand, fulfilling the principle of publicity of the norms, as it constitutes a basis for the efficiency of those, and, on the other hand, fulfilling a general function of information about the activities of public authorities. As the action of government generalises, this function of communication between those governing and those governed has extended to other fields of activity, thus, free and pay materials, both printed and electronic, are published.     

Regression Analysis and the Sociological Imagination

Regression analysis is an important aspect of most introductory statistics courses in sociology but is often presented in contexts divorced from the central concerns that bring students into the discipline. Consequently, we present five lesson ideas that emerge from a regression analysis of income inequality and mortality in the USA and Canada.     

Validity and reliability of a new field test (Carminatti's test) for soccer players compared with laboratory-based measures

The aim of this study was to assess the validity (Study 1) and reliability (Study 2) of a novel intermittent running test (Carminatti's test) for physiological assessment of soccer players. In Study 1, 28 players performed Carminatti's test, a repeated sprint ability test, and an intermittent treadmill test. In Study 2, 24 players performed Carminatti's test twice within 72 h to determine test-retest reliability. Carminatti's test required the participants to complete repeated bouts of 5 × 12 s shuttle running at progressively faster speeds until volitional exhaustion. The 12 s bouts were separated by 6 s recovery periods, making each stage 90 s in duration. The initial running distance was set at 15 m and was increased by 1 m at each stage (90 s). The repeated sprint ability test required the participants to perform 7 × 34.2 m maximal effort sprints separated by 25 s recovery. During the intermittent treadmill test, the initial velocity of 9.0 km · h(-1) was increased by 1.2 km · h(-1) every 3 min until volitional exhaustion. No significant difference (P > 0.05) was observed between Carminatti's test peak running velocity and speed at VO(2max) (v-VO(2max)). Peak running velocity in Carminatti's test was strongly correlated with v-VO(2max) (r = 0.74, P < 0.01), and highly associated with velocity at the onset of blood lactate accumulation (r = 0.63, P < 0.01). Mean sprint time was strongly associated with peak running velocity in Carminatti's test (r = -0.71, P < 0.01). The intraclass correlation was 0.94 with a coefficient of variation of 1.4%. In conclusion, Carminatti's test appears to be avalid and reliable measure of physical fitness and of the ability to perform intermittent high-intensity exercise in soccer players.     

Effects of cigarette smoking on cardiac autonomic function during dynamic exercise

The purpose of this study was to investigate the acute effect of cigarette smoking on cardiac autonomic function in young adult smokers during dynamic exercise. Fourteen healthy young smokers (21.4 ± 3.4 years) performed peak and submaximal exercise protocols under control and smoking conditions. Resting and submaximal beat-to-beat R-R series were recorded and spectrally decomposed using the fast Fourier transformation. Smoking resulted in a significant decrease in work time, VO(2peak) and peak O(2) pulse (P < 0.05). Heart rate increased at rest and during submaximal exercise after smoking (P < 0.05). The raw high frequency and low frequency power were significantly reduced by smoking, both at rest and during exercise (P < 0.05). The low to high frequency ratio was higher after smoking (P < 0.05). The normalised low frequency power was also significantly increased by smoking, but only at rest (P < 0.05). These data demonstrate that the tachycardic effect elicited by smoking is accompanied by acute changes in heart rate spectral components both at rest and during exercise. Therefore, the cardiac autonomic control is altered by smoking not only at rest, but also during exercise, resulting in reduced vagal modulation and increased sympathetic dominance.
