Formación corporal motora. Una noción que se construye con los sujetos de enseñanza en Educación Física

Según el Plan de estudios 435/03 del Profesorado en Educación Física que se dicta en el Centro Regional Universitario Bariloche dependiente de la Universidad Nacional del Comahue existe, en los trayectos formativos de primer, segundo y tercer año, una asignatura cuya denominación es Formación Corporal Motora en adelante (FCM). En la misma se ha intentado, durante estos años, articular disciplinas deportivas como el Atletismo, la Gimnasia y la Natación. En esta comunicación se trata el encuadrede conocimiento que se desarrolla en la asignatura FCM3 del tercer nivel de la formación, planteando un espacio diferente respecto a la construcción de corporeidad y motricidad del sujeto. Se plantea como alternativa a las perspectivas gimnástica- higienista y físico-deportiva en la formación de profesionales de la Educación Física.Entonces ¿cómo se visibiliza la formación corporal motora del sujeto desde la enseñanza de las destrezas en las diversas propuestas pedagógicas? En este sentido, nada de lo que se lleve adelante en la enseñanza es ni neutral ni inocente,está teñido de sentido, de significado, de poder y de utopía. Siguiendo a Zerbino el reto es preguntarse ¿"qué estamos sosteniendo con aquello que hacemos"?

The List of Social Situation Problems: Reliability and validity in an adolescent Spanish-speaking sample

The aim of this study was to analyze the psychometric properties of the Spanish translation of the List of Social Situation Problems (LSSP; S. H. Spence, 1980). The questionnaire was administered to a sample of 388 adolescents between the ages of 12 and 18. Exploratory factor analysis identified four factors: Social Anxiety, Adult Oppositional, Assertiveness, and Making Friends, which accounted for 26.64% of the variance. Internal consistency of the total scale was high (alpha = .86). Correlations between the LSSP and two self-report measures of social anxiety, the Questionnaire about Interpersonal Difficulties for Adolescents (r = .45) and the Social Phobia and Anxiety Inventory (r = .48), were statistically significant. A significant difference was found between LSSP total scores for adolescents with and without social anxiety (d = 1.14), supporting the construct validity of the scale.

Partnerships in mental health: Addressing barriers to social inclusion

Current trends in mental health services emphasize working in partnership with consumers and other government and non-government community organizations for improvement in quality of life for service users. People with a mental illness experience social exclusion, thereby limiting their ability to participate fully in community life. Occupational therapists have a substantial role to play in helping service users to overcome barriers to their community inclusion. Partnerships need to be formed to increase access to community resources and participation in activities that are enjoyed by other members of the community. Such partnerships have a health promotion emphasis and foster the relationship between mental-health services and the wider community, thus shifting the focus from direct occupational therapy service delivery to community-based rehabilitation interventions.This article describes the development, implementation and evaluation of an Australian healthy lifestyle course devised to meet the identified rehabilitation goals of people with mental illness to lose weight, get fit, commence vocational study and get a job. The course was run in partnership between mental health consumers, occupational therapists from the St George Mental Health Rehabilitation Service and staff and students from the Sutherland College of Technical and Further Education.

Impaired memory and olfactory performance in NaSi-1 sulphate transporter deficient mice

In the present study, NaSi-l sulphate transporter knock-out (Nas1-/-) mice, an animal model of hyposulphataernia, were examined for spatial memory and learning in a Morris water maze, and for olfactory function in a cookie test. The Nas1-/- mice displayed significantly (P < 0.05) increased latencies to find an escape platform in the reversal teaming trials at 2 days but not 1 day after the last acquisition trial in a Morris water maze test. suggesting that Nas1-/- mice may have proactive memory interference. While the wild-type (Ncis1+/+) mice showed a significant (P < 0.02) decrease in time to locate a hidden food reward over four trials after overnight fasting, Nas1-/- mice did not change their performance, resulting in significantly (P < 0.05) higher latencies when compared to their Nas1+/+ littermates. There were no significant differences between Nas1-/- and Nas1+/+ mice in the cookie test after moderate food deprivation. In addition, both Nas1-/- and Nas1+/+ mice displayed similar escape latencies in the acquisition phase of the Morris water maze test, suggesting that learning, motivation, vision and motor skills required for the task may not be affected in Nas1-/- mice. This is the first study to demonstrate an impairment in memory and olfactory performance in the hyposulphataemic Nas1-/- mouse. (c) 2004 Elsevier B.V. All rights reserved.

Muscle synergies at the elbow in static and oscillating isometric torque tasks with dual degrees of freedom

This study's aim was to identify the effect of oscillation of torques in isometric tasks under identical mechanical conditions on the muscle synergies used. It was hypothesized that bi-functional muscles would play a lesser role in torque oscillation, because they would also generate an undesired oscillation. Thus, changes in muscle synergies were expected as a consequence of oscillation in torque generation. The effect of the trajectory of torque generation was investigated in dual-degrees-of-freedom submaximal isometric oscillation torque tasks at the elbow. The torques were flexion-extension and supination-pronation. Oscillation torques were compared with static torque generations at four torque positions during oscillation. Muscle activity was determined with surface electromyography. Compared with the static torque tasks, the oscillation tasks showed an overall increased muscle activity. The oscillation tasks, however, showed similar activity patterns and muscle synergies compared to the static composite tasks. It was found that the motor system is well able to control different orthogonal combinations of slow torque oscillations and constant torques by employing a single oscillating muscle synergy.

Interventions for improving self-awareness following acquired brain injury

Accurate self-awareness in clients who have had an acquired brain injury (ABI) has been associated with positive outcomes. However, providing intervention that improves clients' self-awareness is a challenging task for occupational therapists. The present paper provides an overview of the literature regarding models to guide intervention, intervention considerations, descriptions of interventions, and research evidence for interventions. Professionals can draw upon cognitive rehabilitation models and specific models of self-awareness. Facilitatory interventions, such as education, feedback, behaviour therapy and psychotherapy have been recommended to a greater extent than compensatory interventions. The development of interventions for improving self-awareness is at an early stage, and research on the effectiveness of interventions is limited. Future research is required into the effectiveness of interventions to improve clients' self-awareness before structured intervention guidelines can be developed.

Cerebellar morphology in developmental dyslexia

Recent evidence has suggested cerebellar anomalies in developmental dyslexia. Therefore, we investigated cerebellar morphology in subjects with documented reading disabilities. We obtained T1-weighted magnetic resonance images in the coronal and sagittal planes from 11 males with prior histories of developmental dyslexia, and nine similarly-aged male controls. Proton magnetic resonance spectra (TE=136 ms, TR=2.4 s) were obtained bilaterally in the cerebellum. Phonological decoding skill was measured using non-word reading. Handedness was assessed using both the Annett questionnaire of hand preference and Annett’s peg moving task. Cerebellar symmetry was observed in the dyslexics but there was significant asymmetry (right grey matter>left grey matter) in controls. The interpretation of these results depended whether a motor- or questionnaire-based method was used to determine handedness. The degree of cerebellar symmetry was correlated with the severity of dyslexics’ phonological decoding deficit. Those with more symmetric cerebella made more errors on a nonsense word reading measure of phonological decoding ability. Left cerebellar metabolite ratios were shown to correlate significantly with the degree of cerebellar asymmetry (P<0.05) in controls. This relationship was absent in developmental dyslexics. Cerebellar morphology reflects the higher degree of symmetry found previously in the temporal and parietal cortex of dyslexics. The relationship of cerebellar asymmetry to phonological decoding ability and handedness, together with our previous finding of altered metabolite ratios in the cerebellum of dyslexics, lead us to suggest that there are alterations in the neurological organisation of the cerebellum which relate to phonological decoding skills, in addition to motor skills and handedness.

Youth Sports: Implementing Findings and Moving Forward with Research

This paper reviews the literature, outlines practical implications, and discusses future studies in youth sport researc h. The literature is discussed in light of three potential benefits of youth sport participation 1) physic al health, 2) psycho- social development, and 3) motor skills acquisition. The ultimate objective of youth sport programs is to consider all the benefits of youth sport participation rather than focusing on one or two at the cost of the other(s). It is suggested that researchers, s port administrators, coaches, and parents work together to promote sporting activities and programs that are more likely to enhance children’s physical health, psychosocia l development and lifelong recreational or elite sport participation.
