The diagnosis and evaluation of scoliosis is done by carrying out X-rays. A protocol is implemented for tracking the evolution of a scoliosis which involves both clinical control and imaging (X-ray) every 6 months, until the end of the growth period of the child. Because investigations such as X-ray and CT, can have harmful effects on the child's growing body (recent studies have shown that X-ray affects the skin, eyes, hematopoietic tissue, gonads and may cause cancer), new methods for diagnosing and tracking the evolution in time were researched. The present paper tries to present the current methods used in the diagnosis and assessment of scoliosis evolution in time, pointing out the main advantages and disadvantages of each method. There are a few methods developed in recent years in Germany by Zebris Medical Gmbh (using mapping with ultrasonic digital equipment), in Canada by InSpeck (using three-dimensional mapping through digital image acquisition) but used on a small scale. The newly developed methods have the advantage of being non-invasive, painless, non-irradiating and they can be used regardless of health status or gender. Although medical technology has developed very rapidly in recent years, radiology remains the most common method of investigation used for scoliosis. Certainly, in the near future the methods presented in this paper could be used more widely, for the benefits arising from their use.</p></abstract>ARTICLEtrue of some physical fitness characteristics at age 11 to 13<abstract><title style='display:none'>Abstract</title><p>Many studies indicate that an adequate physical fitness is an important marker for a healthy body and a healthy mind.

At this age, skills like coordination, speed or the two combined, namely agility, are developed the best. Agility is an important characteristic of motor development, a quality needed to maintain and control body position while changing direction.</p><p>Our study focuses on a primary school class that practices physical education and we tried to see how they develop their combined coordination and speed skills. We choose to use a set of six agility tests that analyze the main components of agility like speed of movement, lateral movement, balance, coordination: Illinois Agility, Agility T-test, Agility Cone, Box Drill, AFL Agility, Arrowhead agility test and so on. After using some specific programs to develop speed and coordination we used the same tests and saw the improved results. We had two groups that we worked with, first group, the experimental group, included 16 students (age 10±1.3 years; body mass 40.3±5.4 kg; body height 142.3±5.1); the control group, included 19 students (age 10±1.6 years; body mass 43.6±3.4 kg; body height 138.5±4.7).</p><p>Results showed that the experimental group developed skills like speed, coordination and agility easier than the other group. Statistically significant differences were determined within the experimental group both in the initial and in the final tests (p&lt;0.05), also significant differences were discovered between the experimental and the control group in the final measurement (p&lt;0.05).</p><p>Conclusions. The Hypothesis of this study was confirmed - participation of young children in special programs for developing agility skills can prove to be very constructive for their future by developing skills like speed, coordination, lateral movement etc.</p></abstract>ARTICLEtrue A rational management of food intake by bodybuilders<abstract><title style='display:none'>Abstract</title><p>Here is how Cédric sees people eating French fries, six month after entering a bodybuilding training room: « If I give it greasy food (speaking about his body), I run the risk of being nauseated by these chips and the organism will not miss out on the chance of stocking all this unhoped for fat, which would ruin 5 weeks of daily efforts. Ridiculous! ». Certain foods become a source of aversion; eating is no longer a pleasure. These words are even more surprising when discovering Cédric’s dietary habits. Indeed, he eats alternatively 33 grams of plain rice and then, one hour later, 100 grams of chicken, which he repeats 16 times a day. In order to stay awake, he takes pure caffeine, in addition to the usual products: vitamins and food supplements. How is such a fast change in food tastes and distastes possible? How does it occur? This can only be understood by examining the logic that governs the world of bodybuilding. Each aspect of life is reorganized around one single aim: maximal muscular development. Thus, increasing muscular mass is the ultimate aim of bodybuilders, which means that pleasure can only come from activities that bring them closer to this aim. Eating becomes a completely instrumental activity; bodybuilders speak of « nutrimentation ». Phases of drastic dieting are followed by calorific orgies. These modifications are the result of the continuous inculcation of puritan ethics which progressively organize every aspect of their life.</p></abstract>ARTICLEtrue differences of volleyball players<abstract><title style='display:none'>Abstract</title><p><italic>Aim:</italic> The paper’s purpose is to determine the existence of differences in anthropometric and postural characteristics in specific sport branches, in this case, to find the ergonomic posture for athletes in the area of volleyball.

Omega-6 and particularly omega-3 fatty acids have important roles in the organism, contributing to the maintenance and promotion of health. The optimal proportion of omega-6/omega-3 fatty acids is 2:1, or even better 1:1. They are involved in normal growth and development, play a role in the prevention of coronary and cardiovascular diseases, of diabetes mellitus, of arterial hypertension, arthritis and cancer. Omega-3 fatty acids mainly have an anti-inflammatory effect, but also act as hypolipidemic and antithrombotic agents. A potential role of omega-3 fatty acids is that of increasing physical performance. Their role in the physical activity refers on one side to the global health of athletes and on the other side to their anti-inflammatory effect, as high intensity physical exercise induces increased free-radical production and microtraumas, with the induction of an inflammatory status. The anti-inflammatory effect of these fatty acids manifests through an increased production of endogenous antioxidant enzymes, through decreasing the production of prostaglandins metabolites, decreasing the production of leukotriene B4, etc. They are also effective on reducing muscle pain post eccentric exercise and on decreasing the severity of bronchoconstriction induced by exercise, as well as improving pulmonary function variables. In conclusion it seems that supplementing diets with omega-3 fatty acids, apart from having benefic effects on health and on the prevention and management of certain affections, proves to be a beneficial for physical activity and athletic performance.</p></abstract>ARTICLEtrue regarding the optimisation of the spike in modern volleyball<abstract><title style='display:none'>Abstract</title><p>The aim of this paper is to analyse in detail the aspects regarding increased efficiency of the spike in the game of volleyball, given the requirements of a flawless technique that will maximize the potential of the players. Our intention was to verify whether the steps of approach are unfolding in a uniformly accelerated motion and are leading to a vertical leap in the desired parameters at the moment of take off. We also wanted to check if the range of upper body motion is a determinant in the efficiency of the spike consisting in a high striking point and a remakable hitting force.</p><p>Material and methods: The video footage was obtained from 6 players of “U” Timisoara's volleyball team and 6 international players. For the analysis and processing of the footage the program Kinovea was used and the following parameters were assessed: striking speed(m/s), range of motion (cm and °), flexion between arm and forearm, angle of arm with the vertical at contact, movement speed for the first, second and third approach steps.</p><p>Results: The international subjects had a 12 cm longer path of the hand in striking motion. Given the shorter segments of “U” Timisoara's players, they compensate by having a 2° larger range of motion, above the elite players. We recorded diferent angles of the spiking arm with the vertical for the 2 groups, namely a mean of 24.5° for the elite players and just 15° for the players of “U” Timisoara. These aspects lead to a striking speed 3m/s higher for the international spikers compared to “U” Timisoara sportsmen. Having measured a uniformly accelerated approach for the international subjects, “U” Timisoara's players don't respond to the same requirement with close values of the second and third step of approach.</p></abstract>ARTICLEtrue regarding the managers’ behavior towards employees within sports organizations<abstract><title style='display:none'>Abstract</title><p>Starting from the definitions found in the literature, according to which the management is strictly related to the manner in which managers behave and act in their relationship with the employees and to the manner in which their behavior can influence the subordinates’ motivation, the conducted research wishes to establish the presence of these elements in the daily activities and their role increasing performance within sports organizations.</p><p>Therefore, based on the analysis of the data gathered through the survey, a series of action plans can be outlined for the improvement of the work relationships at the level of managers and employees.</p></abstract>ARTICLEtrue study on bodyweight and body fat among students from the Physical Education and Sport Faculty in Iaşi<abstract><title style='display:none'>Abstract</title><p>This papers aims at identifying the mean body mass index and body fat percentage among students from Physical Education and Sport Faculty in Iaşi.</p><p>The study was conducted on a series of 297 students majoring in Physical Education and Sports, but also in Kinetotherapy and Special Motricity (bachelor studies and master studies). By determining the body mass index mean and body fat mean for students within five specialties, we managed to classify them into categories. The assessment of body mass index was conducted using the standard formula BMI= weight in kilograms/height in meters<sup>2</sup> and that of body fat using the Fat Track II body fat calliper.</p><p>Research findings highlighted that the body mass index mean values for each academic year range within normal parameters. As for body fat, the mean value of all academic years ranges in the “very good” and “good” categories. Whereas most mean values range within normal limits, it must not be neglected that overweight or underweight cases were also pinpointed, which should be a warning sign for the future specialists in the field of Physical Education and Sports.</p></abstract>ARTICLEtrue on the correlation between real body and body image<abstract><title style='display:none'>Abstract</title><p>Every individual in the society has a representation of it's own body in relation to the spatial cues, postural cues, time cues, etc., considered by specialists the body scheme. Throughout its development, the human being goes through different stages of organization of both the image the and body scheme. We start carrying out this study from the idea that there could be, in male individuals, a link between body representation (own image projected outwardly apparent by reference to an image presented through a questionnaire) and anthropological parameters, such as body fat and body mass index.</p><p>The study was conducted on a total of 28 subjects, aged 22.71 ± 2.62 years, height of 177.11 ± 6.76 cm and body weight of 73.56 ± 12.60 kg. For these subjects the body composition has been determined by electromagnetic bioimpendance technique and projection of the self was assesed through a questionnaire.</p><p>After analyzing statistical data, our hypothesis was refuted by the lack of mathematical connections between the variables analyzed.</p></abstract>ARTICLEtrue perception in young people Survey in the Italian primary school and comparison with the Maltese school<abstract><title style='display:none'>Abstract</title><p>Here below are the results of a comparative study on the perception of the sports practice in primary school by focusing on the possible differences between genders and classes, and assessing the difference of the sociologic aspects and the media.

There are more discussions regarding the activity of sport performance about objectification, optimization, standardization, rationalization, modeling and other notions which had no meaning for the coaches and players during the romantical period of the basketball game. Tracking a team’s basketball game means more than just gathering information about the individual or collective style of play. If the statistics about the opponent are made, in general, to exploit their weaknesses, the statistics which are focusing on their own team, help to determine not only if the players are useful or harmful, but it also shows their progress or their setback in a competitive season.</p><p>The purpose of this study is to analyze the efficiency of the female players from a basketball team during a competitive season, depending on the season period (first half-second half), the training methods of the coaches, the places where the games are being held (home-away) and the opponent’s level.</p></abstract>ARTICLEtrue of a home-based physical therapy program in patients with chronic low back pain<abstract><title style='display:none'>Abstract</title><p><italic>Aim</italic>: To demonstrate the effectiveness of a home-based physical therapy program on pain, spine mobility and quality of daily activities in patients with chronic low back pain (CLBP). We also want to show that patients who undergo this program decreased their intake in analgesic and anti-inflammatory drugs. <italic>Methods</italic>: 18 patients with chronic low back pain were assessed with the following tests: VAS pain scale, Schober’s test and Rolland-Morris questionnaire. Acetaminophen and nonsteroidal anti-inflammatory drugs (NSAID) consumption was recorded. Over a period of six months all subjects participated in a 45 minutes home-based physical therapy program, three times per week. Before starting this intervention all patients were instructed and exercises were demonstrated in front of them by a physical therapist. Moreover, they received written brochures in order to exercise correctly at home. Follow-up examinations took place at baseline and six months later. <italic>Results</italic>: We obtained significant differences between pre- and post-intervention assessments of pain (p=0.001), lumbar flexion (p=0.0001) and functional status (p=0.0005) in our group. Moreover, the number of patients who were taken analgesics decreased from 7 (39%) to 5 patients (28%). Likewise the number of patients who were taken anti-inflammatory drugs decreased from 11 (61%) to 8 (44%). <italic>Conclusion:</italic> The home-based rehabilitation program was effective in improving the ranges of active lumbar flexion and in decreasing the physical disability caused by low back pain, as well as in reducing the levels of pain. We note that a larger number of patients have given up to the intake of NSAIDs comparative to those who have given up to analgesics.</p></abstract>ARTICLEtrue effect on reaction speed and lower limbs power<abstract><title style='display:none'>Abstract</title><p><italic>Background:</italic> Acetaminophen (also known as Tylenol or Paracetamol) is a very popular drug, that requires no prescription and is usually used as analgesic and antipyretic. A considerable number of previous studies show that acetaminophen has no effects that could alter exercise capacity or performance. On the other hand, there are studies sustaining that exercise performance can be improved with acetaminophen through a reduction in perceived pain, and also a reduction of the body heat produced by the muscle contraction. <italic>Purpose:</italic> The aim of our study was to check if acetaminophen influences reaction speed and power of the lower limbs muscles. <italic>Participants and method:</italic> For this study we recruited twenty-nine males, aged between 19 and 28 years old. We had two testing sessions for each participant, in the same day (the baseline evaluation, and the second evaluation at half an hour after acetaminophen ingestion). The evaluation sequence was: Body composition evaluation, acoustic-visual reaction test for one leg (left and right), Squad jump on one leg (5 jumps on each foot) and Stiffness test (7 jumps on each foot). <italic>Results:</italic> Acetaminophen has no significant influence on visual and acoustic reaction time of left or right leg. The Squat Jump test revealeda significant increase of explosive power on left leg (from 10.19±1.66 to 10.61±1.66 W/Kg, p=0.03) and right leg (10.16±1.59 W/Kg to 10.62±1.84 W/Kg, p=0.02). Another significant result of our study is the increase of reactive power (obtained during the Stiffness test) after the acetaminophen ingestion (from 16.35±4.86 to 17.53±3.79 W/Kg on left leg and from 15.92±4.2 to 17.04±4.26 W/Kg on right leg). <italic>Conclusions</italic>: Acetaminophen ingestion does not influence visual or acoustic reaction time but can improve the exercise performance through an increase in both explosive and reactive power of lower limbs.</p></abstract>ARTICLEtrue the sense of rhythm in primary education students<abstract><title style='display:none'>Abstract</title><p><italic>Background:</italic> Rhythm as a core element of complex coordination is the key to efficient moulding of motor skills specific to sports activities in curricula. Practicing physical exercise in a varied rhythm and tempo in primary school students moulds the skill of achieving correct movement basics (direction, span, coordination, and expressivity). The use of music in sports classes improves kinetics and vestibular sensitivity. The sense of rhythm and tempo are imperative criteria in vocational schools. <italic>Purpose:</italic> This paper aims to describe a pattern of means selected to develop the sense of rhythm and to allow movements in different sports branches with increased efficiency. <italic>Methods:</italic> The test battery was applied on a sample of 15 students from the 4th grade of the “Ion Vidu” National Arts College in Timisoara, Romania, aged 9-10 years, over an entire school year, using different rhythms and tempos during sports classes, which were later used in gymnastics, athletic events, and basketball. <italic>Results:</italic> Data recorded after the application tests, processed and interpreted confirms the proposed assumption and validates the motor contents used. Conclusions: Sense of rhythm is a component of coordinative capacity that is required to be educated from an early age. Rhythmic movements are easier to automate saving energy and motivating students to an active and conscious participation.</p></abstract>ARTICLEtrue frequency and body composition of elite Romanian rugby players<abstract><title style='display:none'>Abstract</title><p><italic>Background:</italic> The physical exertion in the game of rugby is intense and depends on the playing position. This study hypothesized that peculiarities of body composition are important and should be properly interpreted in order to improve fitness and particularly in order to reduce the risk of injuries. <italic>Purpose:</italic> The aim of the present paper is to highlight the importance of body composition evaluation and to underline the usefulness of the data thus obtained for both training individualization and sports injuries risk reduction. <italic>Material and Methods:</italic> Thirty seven senior male rugby players from the former Romanian national team were assessed on body composition using a segmental multi-frequency bio-impedance analyzer InBody 720 (The Body Composition Analyzer – South Korea). We compared the results from both the preseason and the regular season 2012 with the international norms for elite players and we categorized the data by playing positions. <italic>Results:</italic> We have analyzed the amount of lean mass on each limb (kg), body water content (l), percentage of body fat, bone mineral and protein content (kg). We observed that the number of injuries is directly correlated to high levels of body fat percentage, low lean mass, and edema scores. <italic>Conclusions:</italic> The risk of injury can be identified among elite rugby players not only by using fitness tests, but also by using a simple and objective test of body composition. These results show how important it is to monitor the level of body fat, lean muscle mass and muscular development in order to modify nutrition and food habits, individualize trainings and thus reduce the number of injuries.</p></abstract>ARTICLEtrue opinion of Romanian male tennis players about the importance of mental trainining<abstract><title style='display:none'>Abstract</title><p>The aim of this paper is to analyze the importance of mental preparation for competition in Romanian tennis players. We collected data from 67 Romanian male tennis players (mean age: 24 years) by means of questionnaires. Thus, we applied two questionnaires: a demographic test and SCAT - Sport Competition Anxiety Test. Data were analyzed using SPSS Statistics version 20.0. The results indicate fourth aspects of the analyze: who is in charge with the mental preparation, if the athletes know the modern technics used by the specialists for the mental training for competition, the opinion about necessity of mental training and some aspects of anxiety and the strategies to combat it. The conclusions indicate that the mental preparation under the supervision of a specialist is not high practiced by the Romanian tennis players. The need for a specialist is demanded especially to control the emotions before the competition. The current practice to combat the anxiety is music listening, separation from the group, praying or respiration exercise. There is a largely need to improve this technics.</p></abstract>ARTICLEtrue rehabilitation management after hip arthroplasty: a case report<abstract><title style='display:none'>Abstract</title><p><italic>Aim:</italic> In this paper we describe the physical therapy management of a 64-year-old female following a bilateral hip arthroplasty. <italic>Method:</italic> The patient featured in this study, after the surgical intervention had undergone specific recovery treatment consisting of: posture techniques, static (isometric contractions) and dynamic kinetic techniques (passive motion, passive-actives, actives, actives with resistance), massage, respiratory gymnastics and reeducation of walking. <italic>Results:</italic> At the end of the rehabilitation program, hip muscular strength and joint range of motion were improved significantly.
