Men are different from animals for the skill in living in erect position . In the quadruper the stability depends from a large polygon of support ,while in the man the area of support of the feet is rather limited and its barycentre falls more aloft, with many difficulties in the search of the equilibrium .
The erect position is not original in the man but it depends from "learning". With the development of the human species the man has èassed by the crawling position to that quadruped and subsequently to that erect . The man has modified his structural and functional order aìfor competing with the force of gravity and stabilizing his equilibrium. The human body performs some movements according to various degrees of angular liberty; it must modify his geometric order and it must continuously seek the centre of gravity for restoring the equilibrium.
The aim of this study is to analyze the posture in a sample of 63 sedentary young people, for observing alterations that can to produce future problems in the coordination of movement.

In Schmidt and Wrisberg' model (2000), timing is described as a deep component of motor programs and it is a very important element in planning voluntary movements. In this study we focused on the influence that the timing may have on motor programming of a technical gesture as the swing in golf. Recently , some authors have turned their attention to this facet of motor action and there is a general agreement on the influence that acoustic perception have on the timing of a specific movement (Agostini et al,2004; Righi et al.2007; Effenberg,1996).
In fact, acoustic stimulation has been used to standardize ad improve sport performances.
The aim of this study was to control whether the acoustic stimulation associated with the best individual performance improved performance in relation to visual stimulation and the absence of stimulation. The experiment was carried out at Asolo Golf Club (Italy) and participated 12 expert golfers with at least 10 years of experience and a handicap between 10 and -3 . All subjects were treated with acoustic stimulation, visual stimulation and no stimulation before the execution of technical movements. The results show that acoustic stimulation leads to better performance than the other two conditions, confirming the hypothesis. In particular , the acoustic model improve the ability od golfers to shoot the ball near the hole, provide distance information, with a strong effect on standardization of golfers movement and leads the athletes to give higher evaluation of their performance.

For a long time health was associated with a negative meaning: "the disease". For several years , however, the term health has taken a meaning much broader recruiting puzzle pieces that are different areas as genetics, economics, physical environment, acces to service and lifestyle.
Among the components that make up the lifestyles, Physical Activity, defined as any body movement associated with muscle contraction, which increases energy expenditure irrespective of the level of intensity, and the Active Lifestyle, defined as behaviour that gives preferences in carrying out daily activities to use if their bodies compared to motor vehicles, have assumed a key role in health promotion.
International and National prevention strategies, heated by WHO (World Health Organization) and CCM (Center for Disease Control, Italy), based their actions on these two aspects of lifestyle: research has shown that it I snot necessary to play vigorous Physical Activity to be physically active, because the share of movement needed it is possible to be recruited in daily activities. These gestures, one established as behaviours, prevent major risk factors.
Despite this evidence the findings on sport practice in Italy (ISTAT,2006) shows a country relatively sedentary, men seem to be more active and more satisfied with their lifestyle while women are less active and less satisfied.
Physical Activity and Active Lifestyle are behaviours on which actions can be taken but in order to develop autonomous choice is essential to stress the importance of adequate social support to deepen the knowledge and procedures to live a Physical Active life.

The purpose of these study was to evaluate the effects on both skill-and health -related components of physical fitness of an annual physical education class in the primary school . Onegundred one children between 7 an 10 years were assigned to 2 experimental group (Kidd and KLess) and a control group (None). The experimental groups attending a two time a week, 60 minutes physical educational class; the control group didn't attend a specifical physical education class.
Through a graphodynamical survey on handwritings and drawings of children of the experimental group it is possible to collect important results, in particular to understand the temperament of the children, the dispositions, the tendency of intelligence and sensibility and to observe the eventual changes of the graphical movement during the period of the research in relation to a specific physical activity.

Aims: The ludic-motor riding teaches to examine and learn the meaning of animal behaviours, develops the collaboration sense and proper behavioural models. The group activity facilitates the acquisition and respect of rules settled in the group.From the motor point of view, equitation permits to improve neuromuscular functions, as the body knowledge and self awareness, regional coordination , general dynamic coordination and balance
Methods: Two students groups have been chosen, the first is a work group, while the second one is a control grou. The first group consises in twelve kids(six boys and six girls, eight kids are six years old ande four kids are seven years ol), attending "Castel Lornano" Sport Horse Centre of Macerata (Italy). The second group includes twelve kids (six girls and six boys, eight kids are six years old and four kids are seven years old) attending "E.Mestica" Comprehensive School of Macerata(Italy)Motor test and relational test have been given to both groups (in two different phases).. MO.VI.T motor test has been used to check motor improvement . Direct observation has been used to detect behaviours and relationships of kids involved in the ludic-motor equitation.
Results: Meaningful improvement in the work group, both in motor and in relational areas. About motor aspects, the work group kids have shown beneficial effect on relation with body scheme, coordination and balance. About effective relational aspects , relevant improvement have been noticed in autonomy, relational and socialization skills.
Conclusions: This work intended to reach motor coordination, essential aim in the execution of vaulting exercises on horse. The socialization and collaboration have been encouraged because the lesson organisation tends toan intense work group., that is fully reached thorugh the respect of rules, execution timens, priorities, and space-time organization.
