Assessing the limitations of the Banister model in monitoring training

The aim of this study was to carry out a statistical analysis of the Banister model to verify how useful it is in monitoring the training programmes of elite swimmers. The accuracy, the ill-conditioning and the stability of this model were thus investigated. The training loads of nine elite swimmers, measured over one season, were related to performances with the Banister model. First, to assess accuracy, the 95% bootstrap confidence interval (95% CI) of parameter estimates and modelled performances were calculated. Second, to study ill-conditioning, the correlation matrix of parameter estimates was computed. Finally, to analyse stability, iterative computation was performed with the same data but minus one performance, chosen at random. Performances were related to training loads for all participants (R(2) = 0.79 +/- 0.13, P < 0.05) and the estimation procedure seemed to be stable. Nevertheless, the range of 95% CI values of the most useful parameters for monitoring training was wide: t(a) = 38 (17, 59), t(f) = 19 (6, 32), t(n) = 19 (7, 35), t(g) = 43 (25, 61). Furthermore, some parameters were highly correlated, making their interpretation worthless. We suggest possible ways to deal with these problems and review alternative methods to model the training-performance relationships.     

Desaturation Patterns Detected by Oximetry in a Large Population of Athletes

Optimal exercise performance in well trained athletes can be affected by arterial oxygen saturation failure. Noninvasive detection of this phenomenon when performing a routine ergometric test can be a valuable tool for subsequent planning of the athlete's training, recovery, and nutrition. Oximetry has been used to this end. The authors studied 339 athletes performing a similar exercise trial under well controlled environmental conditions. Maximum speed, oxygen uptake, and heart rate levels were simultaneously measured. From the obtained data, six patterns were found: (a) athletes in whom oxygen saturation is constant (≥ 95%) during test execution; (b) athletes displaying a progressive desaturation with incremental exercise intensities; (c) athletes presenting a transient desaturation in the anaerobic threshold region; (d) athletes starting with a mild-to-moderate desaturation at the beginning of the test, but reaching normal saturation values at the end; (e) athletes displaying mild-to-moderate desaturation levels throughout the whole test; and (f) athletes displaying a transient desaturation in the anaerobic threshold region and a new desaturation at the end of the test. In conclusion, it is believed that establishment of desaturation patterns by validated oximetry could be a first approach to evaluate the adaptation of the cardiorespiratory system to exercise intensity, helping to improve results.     

Thinking emotions with two-year-old children: an educational programme to improve emotional knowledge in young preschoolers / Pensando las emociones con niños de dos años: un programa educativo para mejorar el conocimiento emocional en primer ciclo de Educación Infantil

Abstract

This article aims to present preliminary data to validate and show the effectiveness of the educational programme Thinking emotions with a sample of children aged two years. To test its effectiveness, a sample of 57 children was selected. The sample was divided into experimental group (N = 38) and control group (N = 19). Participants were evaluated for overall development (Brunet-Lezine) and emotional understanding through two tests (AKT and TEC) before and after the implementation of the programme in the classroom. The tutors implemented the programme during school hours in weekly 45-minute sessions over six months. The results show significant advances in emotion understanding of children in the experimental group versus the control group. Results are discussed considering the implications of early education on emotions and the consequences on psychological wellbeing.     

Evaluating Environmental Education Programmes: Some issues and problems

This article presents the evaluation of a local government programme on environmental education (Programa Integral d'Educació Ambiental de Cornellà PIDEAC—Global Environmental Education Programme of Cornellà) in Catalonia. The programme aimed to change the habits of the local population. The evaluation has deployed quantitative and qualitative techniques in order to find out if that objective had been fulfilled. Its results show that the common understanding of environmental education has actually changed in the local population, although in a different sense than expected. The relationship of several social groups toward environmental issues should be taken into account to explain these results.     

Segmentation of Cinema Audiences: An Exploratory Study Applied to Young Consumers

The cinema exhibition sector in Spain, as well as in the rest of Europe, is a dynamic sector characterised by the present growth of multiplexes and consumer demand after a long period of decline. These changes make it relevant to analyse the cinema attendees' profile from a marketing perspective. To this end, we have developed an exploratory study on segmentation applied to the young cinema attendees. Doing so, we have found three different groups according to benefits sought in their going to the cinema and other demographic and behavioural variables. On the basis of information as such, specific marketing objectives could be set and more efficient strategies designed and implemented.     

Reading prosody development in Spanish children

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were recorded reading aloud a narrative text including short and long declarative, exclamatory and interrogative sentences. Recordings were analysed using Praat software to measure several prosodic features (i.e., pauses, duration, pitch and intensity). We found that third-grade children had not yet developed an adult-like prosody: they made more pauses, had a flatter melodic contour and had difficulty anticipating sentence structure. Fifth-graders displayed some features of adult prosody. Both length and type of sentence influenced the expressiveness of reading in the three groups. We conclude that reading expressiveness is closely related to reading experience and develops in a similar way to decoding and reading speed.
