Methodological aspects regarding the admission criteria to Physical
Education and Sport Faculties for a better insertion on the labor market
- Abstract: Introduction: In the context in which physical activity is considered today to be a profession, the profile faculties must seek both, the readaptation of study programs to the requirements of the labor market and the updating of student recruitment policies. This study‘s aim is to analyse AVU‘s PESF admission trials from a bio-motric perspective, in order to improve the admission methodology.Methods: The study is a longitudinal one, and subjects are applicants from the 2017 and 2018 academic year (N=117, M=25±9.20 years, out of which B=88, F=29). Methodological approach: a statistical analysis of applicants‘ admission trials using the IBM SPSS Statistics 19 (C.I. =95%) programme. Trial results have been equated to grades. Correspondingly, the gathered data has been compared to: 11th and 12th grade curricular areas, with data included in Faculty of Physical Education and Sport‘s Report (University of Bucharest) regarding the bio-motric potential of Romanian students (2015) as well as with admission methodology related data from other faculties.Results: The gathered results – grouped per trial type- are: speed Ms= 7.3±2.47, standing jump Msj=6.6±2.46, push up Mpu= 9.86±0.73, football Mf=8.18±1.71, handball Mh= 6.83±2.82, basketball Mb=6.56±4.24, volleyball Mv=8.87±0.97, gymnastics Mg=7.83±1.94.Conclusions: AVU‘s FEFS admission policy requires better suited trials in relation to the bio-motric potential (qualities and motor skills) of today‘s graduates. Also, FEFS‘ educational offer (meaning study programmes, study subjects, curricular content) must be able to better cover work force dynamics and labour market requirements.

Training effects on physical fitness and vertical jumps of junior handball
players
- Abstract: Introduction: In handball, the time for physical training is limited, because the focus is placed on the technical-tactical and mental aspects. The introduction of specific physical training is crucial in increasing the sports performance. Even though handball is a team sport, match analysis has shown that physical training in modern handball should be pointed towards the specific playing position and individual physical ability of the players.Materials and methods: The subjects who participated in this are from two groups: the control group consisting of 16 junior I athletes aged 16-18 years, from the CSM Resita handball club, and the experimental group represented by 16 junior I athletes aged between 16-18 years old, from the handball club SCM Politehnica Timișoara. On the experimental group, it was applied in addition to the specific training program, an additional strength training program to increase strength and endurance. The tests aimed to evaluate the following parameters: specific power and specific energy of lower and upper limbs or aerobic fitness.Results and discussions: For both dynamometric and endurance tests, statistically significant differences for all parameters have been registered only for the experimental group. The results showed an important improvement in the variables of the experimental group after training.Conclusions: The objective to improve the physical training of junior handball players by applying a complementary training program was achieved.

- Abstract: Introduction: Short distance running is part of the maximum intensity cycling exercises, consisting of combined efforts, each step being performed as a result of a complete impulse, characterized by covering a distance in a shorter time.Objective: This study aims to follow the development of power for the start in short distance speed trials.Material and method: A 26-year-old male athlete, who has been practicing athletics for 14 years, participated in the study, based on the 100-meter flat sprint. The pre-test was performed before the preparation period, the intermediate test after one mesocycle (one month) and the final test after the second mesocycle (after 2 months). The evaluations followed the strength with which 4 exercises were performed (deadlift, clean, power clean and squat) of 6 repetitions each. At the same time, the length of the distance covered in the first three steps from the start was followed. During the two mesocycles, the athlete participated in specific strength development training.Results: After the two-month training period, statistically significant (p<0,05) improvements were observed in 3 of the 4 exercises, with clean improving from 575 W to 626 W, with deadlift from 560 W to 670 W, and at squat from 422 W it reached 676 W. Regarding the result obtained at power clean, an improvement was observed from 556 W to 557 W, statistically insignificant (p = 0.48). At the triple step, there were improvements both when starting with both feet at the same level and when starting with one foot before.Conclusions: Following the results obtained in the three evaluations, we notice that the training program was developed efficiently and that the results improved in all the evaluation tests.

Clinical examination of the sprained knee
- Abstract: Introduction. Patients with knee injuries may be consulted in a first stage by specialists, such as the sports doctor, and in a second stage, depending on the severity of the injury and the therapeutic orientation, it may be necessary to consult an orthopedic surgeon and / or medical rehabilitation.Aim. Particularly important in the traumatic pathology of the knee is the physical examination. It must be rigorous and systematic, because, based on it, a correct diagnosis can be established, which also assesses the severity of the lesions. Only in this way the optimal therapeutic decision be made in order to establish an accurate initial diagnosis and to evaluate the severity of the sprain, depending on which medical or orthopedic-surgical treatment is decided.Methods. Complete and accurate physical examination in the knee sprain, begins with a meticulous anamnestic interview, followed by inspection and palpation. The examination ends with a series of maneuvers to test the various potentially damaged structures of the knee.Results. All the listed elements will allow us to establish the therapeutic management in the recent sprain of the knee and to differentiate the affected structures: sprain with the interest of the collateral ligaments or with the damage of the central pivot, represented by the cruciate ligaments.Conclusion. Although with the advent of imaging investigations methods, which provide particularly important information and the diagnosis becomes much simplified, the stage of the physical examination of the patient in the knee sprain should not be omitted, it is an accessible and extremely useful tool in the orientation toward diagnosis.

Systematic literature review on the use of transcutaneous electrical nerve
stimulation in the early recovery stage after total hip arthroplasty
- Abstract: Purpose: The recovery of periarticular muscles plays a very important in the functional recovery after total hip arthroplasty. This recovery can be optimized by using transcutaneous electrical nerve stimulation (TENS) in addition to recovery exercises. This survey aims to prove the beneficial effects of electrical stimulation in the early recovery of patients with hip prosthesis.Material and method: Searches in 4 databases (PubMed, Google Scholar, Web of Science and ResearchGate) have led to the identification of 38 articles as follows: in PubMed - 5, in Google Scholar - 18, in Web of Science - 11, in ResearchGate – 4.Results: The use of TENS in the early recovery stage after hip arthroplasty is relatively little covered in the literature. Of all the articles studied 4 articles meet the inclusion criteria. The beneficial effects of applying TENS on atrophied muscles are: increased muscle strength, decreased edema, and improved functionality.Conclusions: Although it cannot be recommended as the only treatment method in the early recovery stage after hip arthroplasty, in combination with physical exercises, applying TENS immediately after surgery may help repair atrophied muscles.

Dance therapy for Parkinson’s disease: a systematic review
- Abstract: Introduction: Dance therapy has rapidly gained popularity among patients with Parkinson’s disease because it is an enjoyable form of exercise and can provide multi-dimensional benefits. Clinical studies have shown that dance improves motor symptoms, particularly balance and mobility problems, as well as the overall physical condition of Parkinson’s patients.Purpose: The aim of this paper is to highlight the benefits of dance therapy in the clinical management of parkinsonian patients and also to find out which dance is the most advantageous for use in therapy and whether the type of dance used leads to significantly different results.Methods: This paper is a systematic and topical review. After a keyword search, 20 articles on dance therapy in Parkinson’s disease were selected according to the PRISMA model, using Google Scholar and Pubmed as search engines.Results: As a form of physical exercise, dance incorporates vigorous movement, social interaction and cognitive stimulation. Studies have shown that dance can reduce tremor, bradykinesia and stiffness, increasing forward speed and multi-tasking gait. At the same time, spontaneous balance disturbances improved and the risk of falls decreased. Argentine Tango is the most widely used dance in therapy. Although other forms of dance used in research led to significant changes, tango dance was found to produce changes of greater value. However, all types of dance achieved positive results in terms of physical, motor and psycho-emotional aspects of patients.Conclusion: Dance therapy is a feasible and safe method for the rehabilitation of parkinsonian patients, brings improvements in motor and non-motor signs of Parkinson’s disease and practiced for at least 12 months regularly, slows down the progression of the disease.

Anxiety and athlete performance: a systematic narrative review of the
mutual influence of these concepts
- Abstract: PurposeThis systematic review was designed to assess the existence of a potential bidirectional relationship between competitive anxiety and sport performance among professional athletes. Psychotherapists believe that the relationship between these 2 parameters can be directly proportional and, moreover, can go both ways, as they have systematically observed in the general population.MethodsFor this purpose, a number of 45 descriptive studies were selected from the cybernetic literature to estimate the level of anxiety in competitive athletes, the variables that may influence this parameter and the level of performance achieved as a result. Without therapeutic intervention, anxiety parameters and its covariates were assessed to detect the influence on sport performance and predict the outcome of a competition based on these concepts.ResultsThe systematic review of these studies revealed that competitive anxiety has a major and statistically significant influence on the competitive situation a an athlete, having an important action on their career in the short and long term.ConclusionsThis analysis has succeeded in demonstrating that a certain degree of anxiety, within the limits imposed by the game experience and through fine psychological mechanisms, can become an asset in terms of achieving the chosen goal in the athlete’s career.

Development of the body scheme in children in primary education: a
systematic narrative review of the influence of an intervention plan on
this psychomotor component
- Abstract: AimThe purpose of this review is to summarize the scientific literature that examined the importance of physical activity programs in the development of body scheme in primary school students by identifying methods and tests used to test body scheme on motor development, spatial-temporal orientation and coordination.MethodUsing the electronic databases Research Gate and Web of Science, we searched for articles using key words, including terms related to methods, intervention plan, children’s age and body schemes. We selected only those that followed the influences of an intervention plan on children.ResultsWe selected 30 articles regarding the development of the body scheme, the spatial-temporal orientation and the coordination through an activity plan. The study results in the three categories show a significant influence on body scheme, spatial orientation and coordination. Following the tests applied and the results obtained, we can say that a well-structured program of physical activity influences the child’s development in terms of body scheme. If it is correctly integrated, one can avoid the existence of body diagram disorders that are quite common for children.ConclusionThe harmonious physical development of the child is influenced by a program of physical activity. Early participation in these programs is recomended in order to avoid disorders of body scheme.

Factors Predisposing to Weight Gain in Young Adults during COVID-19 Home
Confinement
- Abstract: IntroductionHome confinement during the COVID-19 pandemic reduced the physical activity level and exacerbated other unhealthy behaviours such as vices and eating disorders. This study analyses the risk factors predisposing to weight gain in young adults during COVID-19 home confinement.Material and methodFour hundred thirty-three students, aged between 19 and 25, participated in an online survey to understand the factors associated with weight gain. The following lifestyle dimensions were investigated in a regression model: physical activity, personal experiences, occupation, risk of vices.ResultsWe have found significant associations between weight gain (as a dependent variable), and frequency of physical activity (p = 0.009), occupational performance (p = 0.002), and alcohol consumption (p = 0.002). Male respondents are more likely to have gained weight during isolation. For an increase of one unit in the frequency of playing sports, we expect an odd of 0.25 (p = 0.048) for the respondents’ weight loss. Moreover, if the occupational performance increases by one unit, a weight decrease by a rate of 0.52 (p =0.02) is expected.ConclusionIn conclusion, young adults less engaged in physical activity, who assessed their occupational performance as lower, and who consumed alcohol more often during home confinement are the most likely to have gained weight.

The Use of Digital Technologies in the Physical Education Lesson: A
Systematic Analysis of Scientific Literature
- Abstract: IntroductionThe development and diversification of digital technologies in modern era has got a tremendous influence in the field of Physical Education too.This research‘s purpose is to examine the previous studies conducted upon the usage of these diverse digital technologies in the instructive and educational process for the subject of Physical Education.MethodsSix electronic databases have been used to select the articles that include the usage of digital technologies for the Physical Education school subject. After applying the exclusion criteria, there have been selected and evaluated 26 scientific articles indexed during the years 2015 – 2016.ResultsWe can notice that the worldwide technology evolution has contributed to the progressive growth of research regarding the usage of digital technologies even for the field of Physical Education. It was established that the technologies used for the lessons can improve the motor or moving skills and can improve the students motivational level for the Physical Education lessons. The current research also shows that digital technologies can be regarded as a way to involve students in cooperating with their peers. Important studies also refer to investigating the effects that short videos have upon the instructive and educational process itself as well as upon the students evaluation during the Physical Education classes. Using digital technologies (iPads, smartphones, tablets, audio players, computers and apps) doesn’t necessarily involves giving up to the traditional methods, but furthermore, using them simultaneously, can improve the entire learning process, increasing the quality of the lessons and attracting the students towards the Physical Education classes. The article also presents some barriers that can appear in the process of integrating these digital technologies into the lessons. We notice that combining more learning methods of teaching (the reverse learning method with different games, learning by following instructions given with the help of augmented reality, integrating different ways of playing) in the course of Physical Education can bring benefits upon the motor abilities or movements performed by students.ConclusionsIn most of the studies that were analysed it can be noticed that positive results in the instructive and educational process were obtained in regard of improving the motor skills, the students learning abilities and motivation as a result of merging and integrating different digital technologies in the Physical Education classes.

The impact of home office setup due to COVID-19 pandemic on IT
professionals′ physical health: a systematic review
- Abstract: IntroductionThe COVID-19 pandemic represented a great reset in terms of how we work; it affected all organizational levels and brought up unexpected challenges, forcing a lot of workers to shift into working from home. A home office may not be suitable for IT professionals as it is not usually designed ergonomically for long-term use. This study aimed to explore the effects of the COVID-19 pandemic on IT professionals’ physical health who hypothetically deal with non-ergonomic workstations at home and with modified workloads.Material and methodThe research was conducted based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) methodology. The scientific material was selected through a search in PubMed, Scopus, Clarivate Analytics, and Google Scholar databases; the eligible studies were published in 2020 and 2021, involved IT professionals who shifted to home office due to the COVID-19 pandemic and analysed the physical health issues related to these changes.ResultsPhysical health outcomes as neck pain and other musculoskeletal complaints, along with increased stress and anxiety, as mental issues, were reported in most of the participants interviewed in the selected studies; the musculoskeletal complaints were strongly influenced by the unexpected changes that came along with working from home in terms of workload and workstations. On the other hand, having a room dedicated to professional activities, an ergonomic workstation, knowing how to adjust the workstation, and increased satisfaction with indoor environmental quality factors in the workspaces were associated with a lower chance of developing new health problems during this period.ConclusionThe present study confirms that in the case of IT professionals there is a strong association between working from home, poor ergonomic workstations and high prevalence of musculoskeletal complaints, and, especially, an increased occurrence of neck pain.

Defensive vs offensive style on clay courts
- Abstract: IntroductionIn tennis, knowledge of the characteristics of different playing styles is essential to achieve the desired results and to improve specialized technical-tactical procedures according to the playing surface on which the match is played, together with the individual and opponents’ peculiarities.PurposeAdopting a style of play that is suited to the individual characteristics of the player, the opponent and the characteristics of the playing surface can improve the chances of winning for the player who is mostly on the defensive. This comparative study aims to highlight the differences between the two players in a tournament on a slow surface, using the chosen methods and means.MethodsThe main research method was the method of analysing the 6 matches using different statistical indices. In doing so, the average results of all 6 matches played by the two players up to the final were compared with the results of the statistical indices of the final match. For this study we have selected the main indices for the topic.ResultsThe results of the study showed that a defensive player spends more time on the court during a tournament. With the help of data analysis and recordings, it can be observed that the offensive or defensive player stands out according to the studied parameters. Some parameters are specific to a style of play. Also, a defensive player with good speed and agility can adapt more easily on a slow surface (clay).ConclusionsThe playing surface can negatively affect the results obtained in major tournaments if the emphasis in training is not placed on developing a game adapted to individual characteristics. Also, the player who can adapt during the match has a better chance of winning a Grand Slam tournament.

Relationship between lower limb power and dynamic stability in volleball
players
- Abstract: IntroductionAs in all team sports, lower limb power is an important quality of any player. Especially when it comes to volleyball, a game that relies on jumping performance on almost every action except reception. Another crucially important quality of the lower limbs is dynamic stability. Without the latter, the frequency of injuries rises, and that is something any coach or player wants to avoid. The question arises: Are the two qualities related'AimThe study aimed to investigate the correlation between lower limb power and force measured using an inertial flywheel training/measuring device and dynamic stability evaluated through the Y balance test.Material and methodThe Y balance test was used for evaluating the lower limb dynamic stability of 8 Romanian volleyball players. In addition, using an inertial flywheel training system (kBox 4 Pro, Exxentric, Sweden) and kMeter II measuring device the following parameters where measured: average force AvF (N), average power AvP (W), concentric peak power ConPP (W), eccentric peak power EccPP(W). The relative peak power RPP (W/kg) was calculated by dividing concentric peak power by the weight of the volleyball player. The subjects performed 8 maximal squats using the kBox harness and the L (0,05 kgm2) flywheelResultsComposite reach distance (CRD) means for the lower limbs have been compared using the t-test and although there is a difference of 1.8%, it isn’t significant, (p<0,001). We have found a direct correlation between the average composite reach distance and relative peak power (r=0.71, p=0.045) and also with the average power (r=0.75, p=0.032) of the lower limbs. The composite reach distance for the right leg correlates with the relative peak power (r=0.73, p=0.036); average force (r=0.73, p=0.039), and average power (r=0.77, p=0.024). For the left leg, however, the only correlation found with the CRD is the average power (r=0.75, p=0.044).ConclusionsThe medium composite reach distance CRDM is directly correlated with the average lower limb power and relative peak power but due to the small sample size, the power of this effect is unknown. CRDR (right leg) significantly correlates with relative peak power, average power but also with average force whereas CRDL (left leg) only correlates with average power. This does not come as a surprise because all the subjects are right side dominant. There is no significant difference between CRDR and CRDL p<0.001. This is quite important because stability asymmetries of the lower limbs may lead to injury.
