Starting from the assumption that motor activities are the perfect environment for socialization, communication and social integration of young people, this study aims to analyze the effectiveness of these activities in improving intergroup relations at the university level. In this research, the samples were composed of two groups, the experimental group (n = 25) with students from the Physical Education specialization and control group B (n = 25), composed of students from the Faculty of Sciences. The sociological survey applied on the two samples aimed to analyze the level of socialization, communication and social integration of students. The findings showed that the experimental group is more united, having a higher level of socialization and communication, compared to the control group B, proving once again the socializing effects of motor activities.

In this research, we tried to discover the motivations considered by the students decisive for active participation in the motor activities proposed within the hours of physical activity and sport. The study had as main research method the survey of views and research sample included a total of 100 students from the University "Lucian Blaga" from Sibiu. Research findings showed that the main motivation of students to practice motor activities were keeping or maintaining optimal health, the need for relaxation or stress relieving, maintaining a physically, mentally, emotionally and socially balance, the attractiveness of motor activities, promoting values in the sphere of socialization, finding new friends, communication, socialization. Gender differences show that opinions are divided, male students consider physical and social motivations as most important while female students consider as exponential for the motor activities the mental and sanogenic effects.

The purposes of this study was: (1) develop a different methodology based on open-source technologies to promote quantitative movement analysis of sport skills as a regular tool in the biomechanics classroom, (2) analyze the expertise and development students’ level during the work labs and finally, (3) access the students’ engagement, motivational status and technology expertise performed in sports biomechanics. First we explore movement analysis with Dartfish software. A second software Kinovea 0.8.15 was used to extract variables for the 2D kinematical analysis and the Excel 2010 was used for data mapping and the statistics treatment (p = 0,05). For the gait study results presented as an example, the statistically significant differences from the overcharge increase (+ 40% of body weight) were found on step time at 1,80 m/s (p=0,029), on the step leng at 1,25 m/s (p=0,001) and at 1,80 m/s (p=0,003), on the leng gait cycle at 1,25 m/s (p=0,011) and at 1,80 m/s (p=0,002), on the torso angle at 1,80 m/s (p=0,000) and on the hip joint angle motion at 1,25 m/s (p=0,000) and at 1,80 m/s (p=0,012). However, we conclude that overcharge (+ 40% body weight) reduce the step time and step lengthy, shorter gait cycle, increase torso frontal flexion (sagittal plane) and increase the hip joint flexion, mainly in the swing phase.The advantage of this type of classroom lab work with students, besides of having no costs, is an increase of their motivation, pushing the passing rates from 45% to 77% last year. The ability of understanding theory concepts has an exponential raise as every new concept has immediate application on the practical analysis performed with Kinovea At phase 4 we will establish the validity and reliability of all 3 softwares: Dartfish, Kinovea, and Tracker and compare sports and rehabilitation movements at 30 fps versus 60 fps

Play fighting is a form of behavior in which partners compete with each other to gain an advantage. Behavior during play fighting largely resembles the behavior in a real fight, where partners encounter, push and pull down onto the ground, trying to get into a position whereby to control or to dominate the opponent. In the play, unlike the fight, movements are exaggerated and performed at a lower intensity, muscles being somewhat less tensed, and certain actions that can cause injury to the partner are inhibited or modified, while offensive-defensive roles will be reversed quite frequently. Play fighting can be considered a type of evolutionary adaptation designed to facilitate those experiences that will shape the cognitive and emotional development necessary for living in social communities. Research undertaken on different mammal species shows that play fighting offers many opportunities for expression and decoding emotions, improves emotional regulation and contributes to the development of coping mechanisms.

Hip osteoarthritis is mainly characterized by articular cartilage lesisons (distrophy, erosions), lack of articular surfaces shape and contour due to femoral head distruction.Aim. This paperwork aims to emphasize the efficiency of a comprehensive rehabilitation program in functional and quality of life improvement and pain reduction, in patients with hip osteoarthritis.Subjects. This study was conducted in Clinical Rehabilitation Hospital from Baile Felix, on a group of 10 patiants with hip arthrosis, aged between 50 and 80 years old, 50% man, 50% woman, average weight &2 kg, IMC 25.6, duration of affection average 17 years, 50% retired from activity, 50% workers. Metods. As assessment tools were used: goniometry, 0-5 scale for muscular force and Womac index for pain and quality of life assessment. The exercise program aimed to increase hip muscle tonus and the increasing of hip jount mobility and stability due to a better crossing of femorla head in the acetabular cavity. Results. After following rehabilitation program, we found the reduction of pain (11±8.18 baseline versus 9±8.18 final), the improvement of hip joint moiblity (4.60±3.28 pretest versus 3.7±3.27 posttest), of physical functioning (43.20±26.75 pretest versus 40.30±26.42 posttest) and of quality of life (59.8±38.12 pretest versus 53±37.70 posttest). Conclusions: A rehabilitation program followed 5 times/ week, for two weeks, can lead to the improvement of hip joint mobility, to an increased muscular force of pelvic girdle and to the impovement of quality of life in patients with hip osteoarthritis.
