Education to see an inquiry into the performance in young female volleyball athletes
No full textThe eye allows encoding and receiving information about movement: it also allows knowing the environment, including space and three-dimensional parameters: therefore it plays a key role in posture. Thus, there is a strong connection between the latter, the visual system and movement. Therefore, the aim of this study was to highlight, through electronic stabilometry in static mode, a correlation, whether or not statistically significant, of any possibility of influencing in an immediate manner the proprioceptive reflexes that link an athlete's extrinsic eye muscles and posture.
Methods
The study was conducted on 18 female volleyball athletes. These were subjected to a Lang test of dominant eye and of hypo-convergence. Then to a stabilometric measurement in upright stance with open and closed eyes both in the cabin and in the open field. After that, to exercises of evocation of the convergence reflexes at close range, with the use of a micro-magnet, and from a distance, using a stereo trainer device. We eventually proceeded to a comparison between the stabilometric recordings in the cabin and in the open field.
Results
There were no statistically significant differences between recordings in the cabin and in the open field. The difference is statistically significant (p<.001), however, on behalf of the condition in the open field in the length parameter, which indicates a greater stability of athletes.
Discussion.
The sporting gesture is mostly influenced by the Tonic Postural System, although there are many other factors that contribute to its success. The data confirm that the volleyball athletes are accustomed to an assessment of their surroundings and have a good stability due to the frequent handling of balance or unsteady conditions.

Does perceived sport competence influence physical activity enjoyment?
Full text linkIn the sport and physical activity (PA) field, enjoyment is a positive affective response to the sport experience (Scanlan & Simons, 1992) and it can also be considered an important factor in promoting active lifestyles and regular PA among school-aged children (Carraro et al., 2008). The aim of thepresent study was to investigate the effects of perceived sport competence on PA enjoyment.
Methods
Partecipants were 394 pupils (173 boys and 221 girls) aged between 12 and 13 years (M=12.2). The Physical Self-Description Questionnaire-Short (PSDQ-S;
Marsh et al., 1994) and the Physical Activity Enjoyment Scale (PACES; Carraro
et al., 2008) were completed. Pearson’s correlation test was used to measure
the association between variables.
Multiple linear regression analysis was conducted to investigate the correlation between PSDQ-S scores (independent variables) and PACES total score (dependent variable).
Results
Pearson’s correlation test revealed the following positive associations
between PSDQ-S variables and PACES total score: endurance (r = .527, p < .001);
flexibility (r = .206, p < .001); strength (r = .365, p < .001); coordination(r = .427, p < .001); sport skill (r = .546, p < .001). Multiple linear regression analysis showed the following score indices: SE = 7.76; t = 20.79; R2 = .363; F(5, 388) = 44.13; p < .001.
Our results highlighted positive associations between physical self-concept scales and PA enjoyment, and our hypothesis that perceived sport competence can be considered a good predictor of PA enjoyment was confirmed. The results could contribute to our understanding of the processes involved in the promotion of active lifestyles and regular PA among young people
Effects of combined training in type 2 diabetes mellitus
Full text linkAim: Whole body Vibration (WBV) is a training methodology used both for the improvement of
neuromuscular performance in healthy subjects (Sitjà-Rabert et al., 2012) and as an instrument in
the treatment of osteoporosis, sarcopenia and metabolic syndrome (Albasini et al., 2010).
The aim of the study was to investigate the effects of an intervention protocol on a sample of
patients with type 2 diabetes.
Methods: A total of 24 patients (8F; 16M) aged between 46 and 76 years (M= 63) were involved in
a specific 3-month program consisting of 3 one-hour sessions per week. For the case history a
Personal File was used. The data relating to the parameters Body Mass Index (BMI), Maximum
Oxygen Consumption (VO2max), Weight and Glycated Hemoglobin (HbA1c) were collected at T0
and at T1. The training protocol included the alternating combination of aerobic exercise and WBV.
Results: at this initial stage of data processing, the BMI and HbA1c were more sensitive to any
changes. The median value of both variables decreased as follows: BMI (= 33.00; = 32.50), HbA1c
(= 8.00; = 7.00). In male compared to female examinees the median value decreased by 1 point.
Conclusions: The alternating combination of aerobic exercise and WBV proved effective for the
two parameters. It would be desirable in the future to increase the sample and evaluate gender
differences
Victimization in primary school bullyng and the role of physical activity inside and outside school
No full textIn the school years between 6 and 10 years old, children identify leaders who can have a positive or negative effect on the dynamics of the class. The aim of this study was to evaluate the degree of victimization among boys and girls during school motor activity and the relationship between victimization and physical activity inside and outside school
Motor activity in water and Fine-lubinsky sindrome
No full textFine-Lubinsky syndrome was described in
1993, as a very rare syndrome which entails
craniofacial anomalies, bilateral hearing loss, cataract,
microstomia (small mouth), central nervous system
abnormalities and psychomotor delay. (Cole P. et al.
2009)
Unusual abnormalities include
brachydactyly*, camptodactyly* and anomalies of the
deciduous dentition. The conditions that contributed to
the onset of the pathology in this specific case, are
genetic recessive.
The article is about a series of water activities
suggested to a 35 year old woman, aimed to improve
balance, maintenance of praxis schemes, strengthen
abdominal muscles, increased mobility of the lumbar
tract of the spinal column, pragmatic competence and
development of intentionality
Effects of physical exercices in 2 type diabetes patients: roule of whole body vibration
Full text linkInternational literature showed aerobic and resistance training, used in therapy of diabetes, are able to improve both metabolism and incidence of diabetes. This is tanks to more sensibility of muscle cells to the insulin.
This presentation is a 12 weeks study on 2 type diabetes patients working with aerobic and resistance training.
Patients were divided into 2 groups: the first one worked with aerobic training and Whole Body Vibration, the second one with aerobic and resistance training
Balance and posture: effects of proprioceptive training on a group of sedentary people
Full text linkAbstract
Objectives: The object of this study was to evaluate the effects of proprioceptive exercises on the parameters
associated with stability and posture and how these changes following the stress offered by a proprioceptive
insole, placed under the plantar surface during the evaluation tests in pre (T0) and post- training (T1). Data
sources: Participants was 19 sedentary subjects (aged 31.4±3.6) divided in experimental group (EG = 4 males
and 6 females) and control group (CG = 3 males and 6 females). The first (EG) performed a proprioceptive
training for the system podalic; the second (CG) performed only postural exercises. The training was done daily
by the subjects, for a duration of 10 weeks. The stabilometric parameters taken into consideration for our study
were: Xmoyen/Ymoyen, Surface, VarVit, AVG/TALG, AVD/TALD, IVV, ROMBERG as they are variables
that allow an immediate interpretation of a person's stability. Results: The t-test in the experimental group (open
eyes) with the insole, showed statistical significance in the VarVit parameter (p =.03 - r =.94); with eyes closed,
the significance was found in the parameter surface (p =.01 - r =.7) with a further reduction of the variation in
velocity/VarVit (p =.07 - r =.6). The control group significantly improved the speed-variance/VarVit in closedeyes
at dynamic mode (p=.04 - r =.06). Main results: The results of this study indicate that "stresses" provided
represent a type of activity capable of effectively activating the proprioceptive control aimed at reducing
disequilibrium. Conclusions: The results of this study show that the solicitations provided through
proprioceptive training represent a type of activity capable of effectively activating proprioceptive control with
the aim of reducing the imbalance

New clinical standard guidelines for stabilometry parameters: differences by gender and age.
No full textStabilometry is an electronic system device that measures and studies the movements of a person in a standing position, to lead it back to stability (anti-fall). In 1985, the
Association Française de Posturologie - AFP published the rules for some postural parameters obtained from a standardized platform (Normes 85-AFP, 1986). Whereas
before, with the rules AFP 85, the detection of the postural parameters was performed in the laboratory, inside a cabin, isolating the person from the surrounding
environment, starting from our work, the measurements are performed in a clinical setting rather than in a research lab, in a cohort of patients, rather than in volunteers,
and conducted in an open environment (open field), always following the same criteria (normal brightness, absence of visual or auditory stimuli, positioning of the feet at
30 degrees, on a new platform that allows the 40 Hz registration, with feet apart, and separated forefoot from the heel, in static mode, open/closed eyes, during 51.2
sec). In this study all postural parameters were recorded in enrolled subjects divided by gender and and age in order to get new clinical guidelines for all stabilometric
parameters and then very significant values of statistacal normality . Postural parameters allow us to diagnose the causes of postural imbalance. All stabilometric
measurements were carried out by the same M.D. in static condition ,in the same clinical environmental conditions, observing criteria of inclusion and exclusion, in 3972
subjects aged from 5 to 87, both with open and closed eyes using the Cyber Sabots equipment (standardized platform with separated feet and detections for forefoot
and rearfoot with a sampling frequency of 40 Hz). The results were subjected to independent statistical analysis at ILEPS University, to have objectivity and
methodological rigor , grouping subjects by gender and age
