Effects of the practice of muscle stretching
No full textStretching is one of the warming methods used by most athletes, because you think would produce, on the one hand, positive effects on athletic performance and, on the other hand, a decrease in the risk of injury. However, despite this wide spread and its enormous application in most sports, stretching is now the subject of numerous controversies of interpretation that are questioning both the effectiveness, the actual usefulness. In fact, the results of scientific studies and sports practice has shown that static stretching would have a negative effect on performance and no reduction in the risk of trauma. Used, instead, for the training of joint mobility can produce significant results as regards the increase in the amplitude articular
Energetic cost in the different running conditions in team sport for the educational teaching method
No full textThis case study aims to assess the energetic cost at different running conditions (RC) with/without a ball on: Linear running and shuttle running with changes of direction (180°). Experimental approach to the problem requires the following tests/devices: Squat Jump/Counter Movement Jump (Op to jump) to assess the strength’s decrease of the lower limbs before/after each test and Ratings of Perceived Exertion after each RC to assess the training load. ANOVA with repeated measures will be used to assess the significant differences for each variable between each RC. The results of this study could be useful to optimize the basketball training load related to the RC in different seasonal periods
The 'autism in school age: Early diagnosis for treatment
No full textAutism is a serious psychiatric disorder that limits the person first and then fit to integrate into society and then to establish relationships with others. For example, pet therapy can be important in facilitating the relationship: the one with the animal, has an immediate relationship. To help children with autism using hippotherapy or dolphin therapy. In the rehabilitation of the child sits like riding without a saddle on its back by enabling him to have resulted from stimulation of rhythm and 'support of the hoof. The treatment of the horse just counteracts the hyperactivity of children with autism. The noise given by the rhythm of the hooves, like the heartbeat of the baby in the womb of the mother felt, that causes a feeling of wellbeing. With the dolphin therapy instead of the child through a kind of return to the womb, just due all'immergersi water. The pet therapy works on many levels. The relationship established between the child and the animal, and the affection that binds them, are all elements that act positively on the affective-emotional and psychophysical realm. The pet therapy has a positive effect on three levels: 1) emotional and psychological. Pets help to ease the loneliness with their needs center around the person's attention: for example, a puppy away from negative thoughts, you feel accepted and promotes interpersonal relationships; 2) at the physical level: the animals are a stimulus to motor activity and a tool for rehabilitation; 3) at play: the animal throughout its life, always manages to have the ability to play, even causing people to play
Physical commitment and specific work for each role in an elite soccer team
No full textThe aim of this study is to detect the differences in physical commitment required for professional
footballers and if there are significant effects between the preseason period and season of the championship
(Second Division Italian); in order to, eventually there are not significant differences, to schedule specific work
sessions for work groups (distinguished by role). The following quantitative variables have been detected:
distance covered, energy cost, metabolic power, distance travelled in high acceleration and in high deceleration.
The team was divided by roles into 5 groups (n=5) and each group included four players. The activities of the
players were monitored using GPS technology with a sampling rate of 10 Hz and in relation to five different
game positions: (CD) Central Defenders, (FB) Full-Backs, (M) Midfielders, (AM) Advanced Midfielders and
(A) Attackers. It has been used the following descriptive statistic (average values, standard deviation, minimum
and maximum values) and checking the normality of distribution (KS test, skewness and kurtosis), and 2x5
ANOVA. The results obtained during season were compared with that acquired at the beginning of the year (preseason)
and significant effects there aren’t between the different groups
Physical activity and its relation to body and ludic expression in childhood
Full text linkThe article discusses the conditions of the relationship between learning and playing through motor activities , considering the latter as a potential place of education and training of the personality. They are then taken into account the function of the game , theories and research on the game, both among children between adult and child. Finally , it is highlighted the interdependence between the game and the motor activity in the evolution of the child, but is exalted above all the recreational
and mobility, as a resource for learning and privileged relationship that allows the child to transform reality according to his inner needs and to realize its potential. The importance of playing with their parents for the child 's educational opportunity , and training to build bonds of intimacy with the people most important to him . Today, however , due to busy engagements of the parents, you are likely to spend little time with their children. It’s good to emphasize the importance of space and time to recover for the game, especially because it is through play that goes deeper communication between children and adults
Fine needle aspiration biopsy of salivary gland lesions. A reappraisal of pitfalls and problems.
No full textTo assess the diagnostic value of fine needle aspiration biopsy in individual lesions of the salivary glands.
STUDY DESIGN:
During a 16-year period (1979-1995), 841 salivary gland lesions were investigated by fine needle aspiration with cytologic examination. The lesions affected the parotid gland area in all cases except 85 and 19, respectively, in which the submandibular gland and oral cavity (more often the palate) were involved.
RESULTS:
Approximately 3% (25/841) of the aspirates were inadequate, and in 97% of cases they represented the result of samplings performed outside our institution. The 816 diagnostic aspirates comprised 245 cases negative for tumor cells (benign cysts, inflammatory, malformed, degenerative lesions), 571 positive for tumor cells (benign; malignant; not otherwise specified [NOS]); metastatic to the salivary gland tissue; or to the intraparotid or periparotid lymph nodes). Among the 245 cases negative for tumor cells, 36 underwent surgery, and the absence of a neoplasm was histologically confirmed in all cases but one (a low grade mucoepidermoid carcinoma, underdiagnosed as a retention cyst). Among the 571 patients having a cytologic diagnosis positive for tumor cells, in 518 the lesion was removed and the tumor nature confirmed. The cytologic diagnosis of a neoplastic lesion demonstrated a good correlation with histology except in an oncocytic adenoma diagnosed as a Warthin's tumor, in a basal cell adenoma diagnosed as pleomorphic adenoma, in a low grade mucoepidermoid carcinoma of the palate diagnosed as a polymorphous low grade adenocarcinoma and in a vegetative intravascular hemangioendothelioma diagnosed as a possible malignant tumor, NOS.
CONCLUSION:
The accuracy was 97%, the sensitivity to the presence of a tumor 98% and the specificity for absence of a neoplasm 98%. Despite the relative rarity of salivary gland tumors, if established diagnostic criteria are present and strictly observed, the great majority of the common variants of the nonneoplastic and both benign and malignant salivary gland tumors can be diagnosed with a high level of accuracy. There remains a proportion of "problem cases" due to the rarity of the lesions, and in these circumstances the uncertainty must be conveyed to the surgeon openly, leaving the diagnosis open, with a few suggested differential diagnoses
SOME ASPECTS ON TEACHING AND LEARNING BY PHYSICAL ACTIVITY
No full textThe aim is to compare some of the principles of learning and to find a specificity o by with reference to the
thought of some authors such as Bruner, Vygotsky and Piaget in correlation on body. Aspects such as
experience, memory, phisycal activity and emotion, can facilitate or hinder the process of learning, in the
light of these pedagogical ideas provide some link with the teaching and educational practices of a school
context. In conclusion, it highlights the aspects on the process by an investigation on theoretical approach
