Embodied effects of posture: Changing emotional and cognitive processes through the body

2018

La cognición y emoción encarnada es un concepto que está revitalizando el interés por estudiar el papel del cuerpo en el procesamiento de información. Este concepto puede definirse como un efecto donde el cuerpo, su estado sensoriomotor, su morfología o su representación mental juega un papel fundamental en la configuración de los procesos cognitivos y emocionales. El cuerpo y sus procesos implicados han recibido escasa atención dentro de las teorías del procesamiento cognitivo que han predominado en las últimas décadas. No obstante, en los últimos años se ha producido un cambio en la forma de entender el procesamiento de la información, ya que la evidencia empírica señala que el cuerpo eje…

Benefits of Yoga practice on body posture and on psychological and cognitive functions in children aged 8-10 years

Background. Many authors have reported benefits related to yoga practice. In particular, the scientific literature showed the influences of yoga on physical performance and cognitive functions. However, only few researches have examined the role of this training practice in children. For this reason, the purpose of the present study was to investigate the effects on body posture and features as self-esteem and attention in children aged 8-10 years. Materials and method. Sixty-five subjects (male n=28, female n=37) aged 8-10 years and attending primary school were enrolled for the study and randomly assigned into an experimental group (EG) which included 28 participants and a control group (…

The role of school physical education on adolescents' fitness levels during the pandemic period from COVID-19: An observational study of the Italian …

2022

ObjectivesIn Italy, in 2013, a new school curriculum with a sport character was established in high schools, called Sports High School (SHS). The aims of this study were: (1) to assess the fitness levels of SHS students who, respecting all the safety rules to limit the spread of COVID-19, practiced physical education (PE) at school with continuity for almost all of 2021, and to compare them with Traditional High School (THS) students; (2) to evaluate as the SHS may have influenced the fitness levels in adolescents.MethodsThis is a case-control study in which thirty participants were enrolled (SHS: n = 15; THS: n = 15). To assess the fitness levels, the following tests were administered: the…

Effects of Schroth method and core stabilization exercises on idiopathic scoliosis: a systematic review and meta-analysis.

2022

Abstract Purpose Conservative approaches such as Schroth exercises and core stabilization exercises showed effective results in the treatment of idiopathic scoliosis. This study aimed to critically evaluate the magnitude effect of Schroth and core stabilization exercises using a systematic review and meta-analysis. Methods This study has been developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The following three databases were searched for articles collection: Web of Science, PubMed, and Google Scholar. The key search terms were: Schroth exercise, core exercise, idiopathic scoliosis, Cobb angle, angle of trunk rotation, an…

The deltoid muscle: an electromyographical analysis of its activity in arm abduction in various body postures

1992

We have carried out an electromyographical examination of the activity of five different regions of the deltoid muscle during abduction/adduction in various body postures with different biomechanical actions of arm gravity. The results show that the deltoid action is highly differentiated in its different regions and is not restricted only to the generation of an abducting moment in the shoulder joint. There is obviously a biomechanical contribution, mainly by its spinal and clavicular regions, to the stabilization of the glenohumeral joint and to the control of the selected plane of abduction.

The effect of body posture on long range time-to-contact estimation

2011

On Earth, gravity accelerates freely moving objects downward, whereas upward-moving objects are being decelerated. Do humans take internalised knowledge of gravity into account when estimating time-to-contact (TTC, the time remaining before the moving object reaches the observer)? To answer this question, we created a motion-prediction task in which participants saw the initial part of an object's trajectory moving on a collision course prior to an occlusion. Observers had to judge when the object would make contact with them. The visual scene was presented with a head-mounted display. Participants lay either supine (looking up) or prone (looking down), suggestive of the ball either rising…

Narcoleptic and schizophrenic hallucinations

2002

The differential diagnosis of narcolepsy versus schizophrenia is sometimes complicated by similar phenomenology, particularly when hallucinations predominate. REM sleep disturbances seem fundamental in the pathophysiology of narcolepsy, and REM sleep intrusions during periods of wakefulness are often associated with hallucinations also in healthy controls and in patients with other brain disorders including schizophrenia. This study used a semistructured interview to investigate different aspects of hallucinations (frequency, modality, content, and dependence on body posture) in 148 patients with narcolepsy, 21 patients with acute exacerbation of a schizophrenic disorder, and 128 healthy su…

Effects of a Postural Exercise Program on Vertical Jump Height in Young Female Volleyball Players with Knee Valgus

2022

Background: Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance. Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus. Methods: This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG); the Valgus Control Group (VCG); and the Neutral Control Group (NCG). All three groups carried out the same volleyball training program. In addition, only the VEG underwent a 3-month postur…
