Study On The Effectiveness Of Using The Nage-No-Kata Programme To Increase The Technicality Index In Adolescent Judo Athletes

Patricia Roxana Fort — 2025-06-07

This study examines the efficacy of a Kata-based technical training programme in improving Judo technique execution. Conducted over eight months (September 27, 2021-April 27, 2022) at the Municipal Sports Club in Bucharest, the experiment involved 16 performance-level judokas with a minimum of five years of experience. A structured Nage-No-Kata programme was implemented three times weekly, with initial and final assessments evaluating Kata performance and competition technique (Ippon scoring). Wilcoxon test results revealed significant improvements (p < 0.05) in Kata execution (W = 3.5, Z = -3.20) and Ippon performance (W = 0, Z = -3.51), with effect sizes of 0.80 and 0.87, respectively, indicating a strong positive impact. The findings of this experiment on the use of the Kata tool in Judo sports training for enhancing technical proficiency show that competitive performance can be improved. However, limiting factors place this study in the position of a starting point for future research on this topic

Mihaela Gavrila-Ardelean — 2025-06-07

The present study explores the influence of emotional and behavioral status on sports performance among students. The relationship between the emotional state and the behaviors associated with sport is complex and bidirectional, influencing the levels of motivation, concentration, resilience and team cohesion (Ionescu, 2018). Thus, it is essential for coaches and teachers to understand these dimensions in order to optimize sports training and support the personal development of students. The paper brings into discussion various theoretical models and empirical research that highlight the role of emotional states in sports performance, providing recommendations for effective interventions.

Improving The Methods Of Training And Selection Of Female Handball Players

Andrei Bitang — 2025-06-07

The theory and methodology of physical education and sports is the science that studies the laws of physical education and sports. Handball is a means of physical education, because it contributes to improving health, harmonious physical development, the development of motor and mental qualities, as well as the acquisition of motor skills. In order to achieve high results, it is necessary to practice it within sports teams in which the training work must be well planned and carried out on a scientific basis. The road to the heights of sports mastery is difficult, requires a lot of work and very careful and, above all, continuous training. However, mastery is achieved faster than in other sports games. The purpose of this work is to develop and experimentally implement a training program that includes proprioceptive means, oriented towards optimizing the means of training and selection of players for the game of handball, juniors III, in order to maximize the use of performance skills. The results obtained in the physical assessment are very good, which indicates that, in the physical training and selection process, means and exercise structures appropriate to the children's age were used.

Educational, Sports, Cultural and Solidarity Tourney: from the point of view of the Sports Organization

Vinicius Barroso Hirota — 2025-06-07

The practice of organizing sports events is a new area of research and therefore requires further studies. The objective of this study was to identify events that have different values and characteristics from traditional sports competitions. To this end, a survey of information about these events and an interview with the organizing committees of these events were carried out. The study was guided by qualitative research, of a descriptive and interpretative nature, involving interviews and documentary research of the events selected for the study. After reading the data, information was gathered to better understand the values of the Educational, Sports, Cultural and Solidarity Tournament (TECSESP). As a result, we found that there is a sports organizational model for holding this event, the organizing committee of TECSESP that seeks to promulgate values that are passed on through the actions of participants and organizers. Because the event is held periodically, it has been structuring itself and seeking to be increasingly aligned with its target audience in a process of collaboration.

Covid-19 And Its Impacts On Students' Attitudes And Behaviours Related To Proper Nutrition, Alcohol Consumption, And Smoking.

Robert Çitozi — 2025-06-07

Albania has experienced tremendous political, social, and economic transformation throughout the 1990s. Among these have been modifications to nutrition, both in terms of quantity and quality. Most people now live in better conditions thanks to the move in the political system towards a free-market economy, which also resulted in more cars on the road. As a result, there was a surge in both environmental pollution and population inactivity, which has been connected to obesity and overweight in all age categories. For children and young people, unhealthy eating habits and physical inactivity have the biggest effects. This study, which involves students from the Faculty of Physical Activity and Recreation practically every year, aimed to determine the prevalence of overweight and obesity, as well as alcohol and cigarette use, in first-year bachelor's students. The study's main goal was to determine whether the Corona virus epidemic had any influence on the results. 140 students were chosen at random between October and November 2021, with a mean age of 18.69 years (58.75% male and 41.42% female participants). The results indicate that some sports university students may benefit from studying a sports nutrition module as well as nutritional and health promotion programs to lessen this propensity, especially in male students, even though the general prevalence of overweight and obesity in the sample investigated is low. We believe that the rise in alcohol and cigarette use since the end of our previous study in 2019 is likely due to isolation during COVID-19, either out of boredom or to deal with tension and anxiety levels that have been reported to rise across the board in all demographic groups.

Investigation of the Effects on Physiological Parameters of Football Players in Pre-season Period

Murat Tutar — 2025-06-07

The pre-season period in football is of great importance in order to optimise the performance of athletes and minimise the risk of injury. The aim of this study was to follow the physiological parameters of the athletes in the first pre-season preparation phase and to determine their readiness levels. Twenty-four professional licensed athletes aged between 18-35 (24.3±5.42) years participated in the study. The body weight and height of the athletes at the beginning of the season were 72.4±7.44 and 180.0±6.33, respectively. At the beginning and at the end of the first preparation phase, fat measurement, squat jump, overhead squat assessment and yo-yo endurance test were performed. The fat percentage obtained as a result of the tests was 7.43±0.73 in the pre-test and 6.99±0.65 in the post-test, 40.25±4.9 in the squat jump pre-test and 41.45±4.8 in the post-test, 17.33±3.5 in the overhead squat assessment pre-test and 19.50±2.1 in the post-test and 1723.3±307.6 in the squat jump pre-test and 1852.08±335.8 in the post-test. According to t-test data, statistically significant differences were found in fat percentage, squat jump, overhead squat evaluation and yoyo data (<.001). According to the results of the study, it can be said that the fat percentage, strength assessment, anaerobic power and endurance skills of the athletes improved in the first pre-season preparation phase.

Comparative Study Between The Heavy Duty Training Method And The Classical Training Method

Narcis Julien Herlo — 2025-06-07

Purpose: The study aims to compare the effectiveness of the Heavy Duty training method with the classical method in the development of muscle strength and hypertrophy, focusing on the biceps brachii and triceps surae muscle groups.
Methods: The research was conducted over a period of 6 months at Panoramic Gym in Arad, involving a sample of 45 volunteers randomly divided into two groups: an experimental group (E.G.) and a control group (C.G.). The E.G. followed the Heavy Duty training method, while the C.G. followed the classical method. Strength tests (pull-ups and calf raises) and anthropometric measurements (arm and calf circumference) were used. Data were analyzed using arithmetic mean and standard deviation.
Results: The E.G. recorded a 19.9% increase in pull-ups and 9.7% in calf raises, while the C.G. showed increases of 16.5% and 4.9%, respectively. Arm circumference increased by 3.3% in the E.G. and 2.7% in the C.G., and calf circumference by 1.9% vs. 1.5%.
Conclusions: The Heavy Duty method generated superior progress in muscle strength and hypertrophy compared to the classical method, demonstrating greater efficiency in stimulating physiological adaptations through short and intense workouts, suitable for advanced athletes.

Effective Methods For Assessing General Strength In High School Students

Georgeta Lucia Piscoi — 2025-06-07

Physical education and sports have particularly large social tasks, and this aspect constitutes a signal of attention for physical education and sports teachers, as high school students are approaching the completion of biological growth
The motor quality strength is present in school curricula at each level of study. In the preparation of students, interdependent relationships are created between the components of the preparation, between the development of motor qualities, the development of morpho-functional indices and the acquisition of motor skills. As research objectives, we aimed to: carry out initial testing on 4 control samples in different classes of the high school cycle and in SAM classes; go through a system of lessons intended for the development of the motor quality strength, a system with increasing intensity and complexity from one year of study to another; establish a set of measures necessary to improve the current teaching and evaluation system in the discipline “Physical Education”. The materials, methods and means used were adapted to the working conditions in an improvised gym, with reduced height, width and length. We specify that there is no possibility of developing strength in a coherent system of lessons due to the delicate period we are going through. The development of motor qualities is necessary to achieve the other requirements of the curriculum. Knowing the level of development of the motor quality strength, as well as its evolution curve is of particular importance, therefore, as results, correlating the data obtained from parallel classes, for each test, as well as for the evolutions recorded in them over the course of one or two years, the values obtained are calculated, differentiated for boys and girls

Effectiveness Of Massage In Recovery From Exercise-Induced Muscle Injury In Older Adults

Marconi Roberto Gabriel — 2025-06-07

The study aims to evaluate massage as a recovery method for joint position, and balance after exercise-induced muscle injury in older adults. One hundred and seventy-five elderly patients performed an exercise session targeting the calf muscles (five exercises, six sets of 15 repetitions to induce muscle damage). The objectives of the study are to evaluate the role of massage and the Scottish cold shower in the recovery of older adult patients. After training, the participants underwent one of the recovery interventions: a 20-minute massage on the calves, a 12–15-minute Scottish cold shower on the lower limbs (12.5 ± 1°C). These interventions were administered immediately after exercise and again at 24, 48 and 72 hours over a period of 21 days. Conclusions: the measurements taken each time included muscle pain, joint position, and postural-balance balance. The treatments and the time allocated to repetitive massage significantly reduced muscle pain and improved balance. Conversely, although they alleviated muscle pain, they did not effectively prevent loss of muscle strength, balance deficits. Therefore, older people who engage in strength training can benefit from massage for longer to help with muscle recovery, improve balance, and reduce the risk of falls.

Pilot Study In Calcified Tendinopathy Of The Shoulder: The Importance Of Targeted Ultrasound-Guided Shock Wave Treatment

Iosif Ilia — 2025-06-07

Calcific tendinopathy of the shoulder is a degenerative disorder marked by calcium accumulation within the rotator cuff tendons, most commonly involving the supraspinatus tendon. This condition is a frequent source of persistent shoulder pain and reduced function, with reported prevalence among symptomatic individuals ranging from 2.5% to 54% (Uhthoff, Sarkar, & Maynard, 1976). A variety of non-surgical treatments are available, including nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, corticosteroid injections, and, in resistant cases, surgery. Recently, extracorporeal shock wave therapy (ESWT) has gained attention as a promising non-invasive treatment option (Brindisino, Marruganti, Lorusso, Cavaggion, & Ristori, 2024). This randomized, controlled, prospective study aimed to be a pilot study in assessing the therapeutic effectiveness of r-ESWT in managing calcific tendinopathy of the shoulder. Two ESWT techniques were compared: one guided by ultrasound to target calcific deposits directly, and the other based on anatomical landmarks focusing on the supraspinatus tendon origin. Materials and Methods: The study included twenty-one patients diagnosed with calcific tendinopathy, randomly divided into two treatment groups. Each participant received three ESWT sessions, with 2000 pulses delivered at 2.2 bars pressure, using an energy level of 5 and frequency of 8Hz. Clinical progress was evaluated using the Constant-Murley Shoulder Outcome Score (CMS) at 12 weeks and six months following treatment. Additionally, ultrasound imaging was used to monitor changes in the calcium deposits.
Results: Patients treated with ultrasound-guided ESWT showed better clinical and imaging results than those who received the landmark-based treatment. The ultrasound-guided group experienced greater pain reduction and functional improvement, along with a significantly higher rate of complete resolution of calcific deposits.
Conclusions: These results highlight the critical role of accurate targeting in maximizing the effectiveness of r-ESWT for shoulder calcific tendinopathy (Haake, Deike, Thon, & Schmitt, 2002).

The Effectiveness Of Kinesiotherapy In Managing The Risk Of Muscle Injuries In Bodybuilders

Claudiu Octavian Bulzan — 2025-06-07

Bodybuilding, as a sports discipline, involves a rigorous training regimen primarily focused on developing muscle hypertrophy and maximal strength. Practiced at both recreational and competitive levels, bodybuilding entails systematic and progressive loading of the musculoskeletal system, resulting in significant biomechanical stress on muscle groups, joints, and myofibrillar units involved (Zemper, 2005). Repeated stress, particularly in the absence of appropriate recovery strategies, increases susceptibility to muscle injuries, which can range from mild muscle strains to partial or complete muscle fiber tears (Orchard & Best, 2002).
Muscle injuries not only affect immediate athletic performance but can also significantly impact the continuity of training, functional balance, and, in severe cases, compromise the athlete’s long-term ability to compete at a high level (Järvinen et al., 2005). Consequently, preventing these dysfunctions has become a strategic priority in modern sports performance management (Ekstrand et al., 2011).

The Importance Of Selection And The Influence Of An Assisted Training Program On The Development Of Motor Skills In Children A Comparative Study

Narcis Julien Herlo — 2025-06-07

The multiple aspects related to the importance of selection in the sports field are one of the fundamental requirements and, at the same time, the premises for successful results in the long term. The objectives of this study were to achieve a rigorous selection, adapted to the specifics of athletic events, considering a variety of parameters that, integrated, outline the general sports profile of the children included in the research.
The methods used included the initial and final testing of the students remaining in the study group, in order to obtain a more objective and precise assessment of the individual motor skills. Before deciding on the inclusion of children in the specialized training process, it is recommended that they follow a unitary basic training program, lasting between 1 and 3 months, to balance the initial level of motor development.
The results obtained highlight significant differences between the two analysed groups. The final mean values support the hypothesis that the students in group A (experimental), who benefited from an additional assisted sports training program, structured according to a SWOT analysis, obtained superior results compared to the control group. This demonstrates the effectiveness of the proposed intervention and the relevance of a well-founded selection, followed by a period of preparation adapted to the specific needs of each child.
