TREINAMENTO DE FORÇA DO CENTRO ABDOMINAL EM JOVENS ESTUDANTES

ABSTRACT Introduction: Recent studies point out that strength training with load may substantially help athletes’ strength, while strength training with moderate load may improve motor coordination. Objective: Investigate the current status of abdominal core strength training in young people, surveying the current problems. Methods: Students from a particular province were selected for the investigation. We performed tests, comparisons, and analyses of results on the abdominal core strength of the exercises practiced in sports schools to provide better support for amateur training. The Abdominal Octopole Strength Bridge Test uses overcoming one's weight. Results: Boys accounted for 59.04% of abdominal core strength, while girls accounted for only 22.50%, with most of them at their average level of 40.00%. The proportion of girls with low scores is also higher (26.25%); in boys, the deficient proportion is 8.77%. Conclusion: There is a significant difference in the abdominal core strength of the students. The expectation of a difference between male and female students not being very large contrasted with the reality, suggesting that girls need to pay attention to abdominal core strength training during training. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Digital Twin in Sport: From an Idea to Realization

A digital twin is a virtual model to reflect a physical object and helps it by making proper decisions. The decision-making process is based on the same input data that the simulated physical object has access to. Due to exploiting artificial intelligence, the decision-making process of the digital twin is more sophisticated than that of the physical object. In this study, the digital twin is applied to the sports training domain, where it addresses those questions that have arisen during the implementation of interval cycling training sessions. Thus, the digital twin runs on a mobile device (i.e., the Raspberry Pi platform), with which a cycle is equipped and demonstrates user-friendliness, robustness, reliability, and accuracy. The interval training sessions are transferred to the mobile device in the form of the domain-specific language EasyTrain, ensuring higher expressive power and ease of use. During the implementation, the digital twin advises the athlete with predicted information obtained by a sophisticated prediction model via a screen. The results of a huge experimental work showed that the difference in the average efficiency of the interval training implementation between the two cyclists that performed the experiments is prominent, as the efficiency of the professional training surpassed 90%, while the amateur training efficiency barely achieved 70%.

Trends and Problems in Designing Architectural Image of Modern Sports and Health Complexes Using the Case of the Moscow Region

Over the past 10 years, the population of Russia has had an increased interest in amateur training. There are many wellness and sports complexes being constructed allowing people to comfortably do sport. This article shows the analysis and identification of characteristic features of volumetric planning solutions and architectural and town-planning design of such complexes. The modern sports and wellness center (SWC) should have versatile and multi-functional planning solutions. Analysis of the objects showed that a modern SWC has a small area of up to 2,000 sq.m. and the number of floors vary from 1 to 3. The complexes are aimed at a wide range of users, at different age groups, in addition to multi-purpose gyms, there are some specialized ones included in the layout: tennis courts, gymnastics, volleyball, swimming pools and skating rinks, as well as additional recreation functions: SPA treatments, baths, nutrition. The structural system of buildings is metal frame one.The volume solution for the complexes varies from simplified to complex forms, facades have various finishing materials and color schemes. The variety of solutions allows to create unique buildings, but at the same time, it makes it difficult to visually identify buildings as sport and wellness centers. The necessity of creating a unified system of visual identities for mass sports facilities was identified.

Characterizing Head Impact Exposure in Men and Women During Boxing and Mixed Martial Arts.

Background:The accumulation of subconcussive impacts has been implicated in permanent neurological impairment. A gap in understanding the relationship between head impacts and neurological function is the lack of precise characterization and quantification of forces that individuals experience during sports training and competition.Purpose:To characterize impact exposure during training and competition among male and female athletes participating in boxing and mixed martial arts (MMA) via an instrumented custom-fit Impact Monitoring Mouthguard (IMM).Study Design:Cross-sectional study; Level of evidence, 3.Methods:Twenty-three athletes (n = 4 women) were provided a custom-fit IMM. The IMM monitored impacts during sparring and competition. All training and competition sessions were videotaped. Video and IMM data were synchronized for post hoc data verification of true positives and substantiation of impact location. IMM data were collected from boxing and MMA athletes at a collaborating site. For each true-positive impact, peak linear acceleration and peak angular acceleration were calculated. Wilcoxon rank sum tests were used to evaluate potential differences in sport, activity type, and sex with respect to each outcome. Differences in impact location were assessed via Kruskal-Wallis tests.Results:IMM data were collected from 53 amateur training sessions and 6 competitions (session range, 5-20 minutes). A total of 896 head impacts (men, n = 786; women, n = 110) were identified using IMM data and video verification: 827 in practice and 69 during competition. MMA and boxers experienced a comparable number of impacts per practice session or competition. In general, MMA impacts produced significantly higher peak angular acceleration than did boxing impacts (P < .001) and were more varied in impact location on the head during competitions. In terms of sex, men experienced a greater number of impacts than women per practice session. However, there was no significant difference between men and women in terms of impact magnitude.Conclusion:Characteristic profiles of head impact exposure differed between boxing and MMA athletes; however, the impact magnitudes were not significantly different for male and female athletes.

Effects of Ultratrail Running on Neuromuscular Function, Muscle Damage and Hydration Status. Differences According to Training Level.

The status of trail running races has exponentially grown in recent years. The present study aimed to: (a) evaluate the acute response of ultratrail racing in terms of neuromuscular function, muscle damage and hydration status; (b) analyze if responses could differ according to training levels. Twenty runners participated in the present study. The participants were divided into amateur training level (n = 10; 43.30 ± 4.52 years) or high level competitors (n = 10; 41.40 ± 6.18). Neuromuscular response (squat jump, countermovement jump and Abalakov jump), muscle damage (alanine aminotransferase, bilirubin, creatine kinase and leukocytes) and hydration status (sodium and creatinine) were evaluated before and after the Guara Somontano Ultratrail Race (108 km distance, with an accumulated slope of 5800 m). The height and power achieved by vertical jumps were lower after the race (p < 0.001). The post-race muscle damage and creatinine parameters increased in both groups (p < 0.001). The high-level group obtained lower percentages of change in squat jump and countermovement jump than the amateur-level group (p < 0.05). However, the increase in creatinine was greater for the high-level group (p < 0.05). Ultratrail racing reduces neuromuscular function and increases muscle damage. High-level runners showed less neuromuscular fatigue compared to amateur ones.

Fair Play in Physical Education and Beyond

The aim of this study is to examine the level of understanding of the principle of fair play by secondary school pupils (n = 827) from the Polish province of Wielkopolska, physical education (PE) students from Poznan University of Physical Education (n = 437), and PE teachers (n = 130). Two structured survey questionnaires were used, namely: The three-level scale known as the Fair Play Moral Dimensions Concept Scale and a Factors of Moral Influence Scale. There were observed differences between male and female students in their comprehension of the principle of fair play regarding the category of sporting activity practiced. The female teachers’ amateur training group more frequently identified the highest level of fair play (32.1% of the examined female teachers) in comparison with their male colleagues. Moreover, differences were noted between boys and girls at the secondary school level. Boys rated the influence of PE teachers and coaches higher, while girls declared that they were more influenced by media and education. For both boys and girls, parents constituted the highest-rated factor of the influence on their moral development. Students also indicated the influence of parents as the highest-rated factor. Among PE teachers, school, as a source of influence on one’s moral development, was awarded higher rates by female than by male teachers. It was observed that parents constituted the highest-rated factor of influence for PE teachers.

The Preventive Effect of the Nordic Hamstring Exercise on Hamstring Injuries in Amateur Soccer Players

Background: Hamstring injuries are the most common muscle injuries in soccer, and they have a high rate of recurrence. Eccentric hamstrings strength is recognized as an important modifiable risk factor. This led to the development of prevention exercises such as the nordic hamstring exercise (NHE). The effectiveness of the NHE on hamstring injury prevention has never been investigated in amateur soccer. Purpose: To investigate the preventive effect of the NHE on the incidence and severity of hamstring injuries in male amateur soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Male amateur soccer players (age, mean ± SD, 24.5 ± 3.8 years) from 40 teams were randomly allocated to an intervention (n = 20 teams, 292 players) or control group (n = 20 teams, 287 players). The intervention group was instructed to perform 25 sessions of NHE in a 13-week period. Both the intervention and control groups performed regular soccer training and were followed for hamstring injury incidence and severity during the 2013 calendar year. At baseline, personal characteristics (eg, age, injury history, field position) were gathered from all participants via a questionnaire. Primary outcome was injury incidence. Secondary outcomes were injury severity and compliance with the intervention protocol. Results: A total of 38 hamstring injuries were recorded, affecting 36 of 579 players (6.2%). The overall injury incidence rate was 0.7 (95% CI, 0.6-0.8) per 1000 player hours, 0.33 (95% CI, 0.25-0.46) in training, and 1.2 (95% CI, 0.82-1.94) in matches. Injury incidence rates were significantly different between the intervention (0.25; 95% CI, 0.19-0.35) and control groups (0.8; 95% CI, 0.61-1.15), χ2(1, n = 579) = 7.865; P = .005. The risk for hamstring injuries was reduced in the intervention group compared with the control group (odds ratio, 0.282; 95% CI, 0.110-0.721) and was statistically significant (P = .005). No statistically significant differences were identified between the intervention and control groups regarding injury severity. Compliance with the intervention protocol was 91%. Conclusion: Incorporating the NHE protocol in regular amateur training significantly reduces hamstring injury incidence, but it does not reduce hamstring injury severity. Compliance with the intervention was excellent.

How can Westerners study Japanese Noh? An interview with Richard Emmert, Director of the Noh Training Project and Theatre Nohgaku

Is it really possible to study Japanese Noh theatre outside of Japan? Can Noh training be meaningful to non-Japanese, yet faithful to traditional training methods? Is amateur training outside of Japan actually all that different to amateur training inside Japan? In this interview, conducted in September 2013, Richard Emmert explains his approach to Noh training inside and outside of Japan, its relationship to traditional modes of instruction, and the possibilities for innovation. He articulates his rationale for the production of Noh in English, and explores how a lack of skilled performers for these projects led to the creation of the various Noh Training Projects held around the world. Above all, he argues that an understanding of Noh's formal complexity is central to training. He suggests that such knowledge enables the full significance of training to be realised, the meaning of innovation in Noh to be discerned, and the discovery of subtle transferable performance skills through a recognition of the relationships between music, movement, and voice.

Imagery Training is easy to operate and does not require any special requirements, only a relatively quiet environment and body relatively relaxed time. Therefore, this article explore the imagery training in aerobics amateur training effect, provide a theoretical basis for the training.

Breakdance Injuries and Overuse Syndromes in Amateurs and Professionals

Background Serious injuries due to breakdancing have been presented only as singular case reports to date. So far, there have been no comprehensive studies about injuries in this sport. Hypothesis Professional breakdancing might lead to a higher incidence of injuries than amateur training. Wearing safety equipment is correlated with a decreased incidence of injuries and pain. Study Design Descriptive epidemiology study. Methods The retrospective study surveyed 40 breakdance professionals and 104 amateurs by questionnaire. Results There were 1665 injuries and 206 overuse syndromes found in 380 588 hours of training, leading to a loss of 10 970.6 training days. Professionals reported significantly (P < .001) more injuries and overuse syndromes with significantly more injuries of the wrist (P < .001), knee (P < .001), hip/thigh (P = .003), ankle/foot (P = .013), and elbow (P = .033). No significant differences were found in the time lost per injury and the time lost per overuse syndrome. Pain occurred most frequently in the region of the wrist, spine, shoulder, and ankle. A negative correlation between protective gear and injuries or frequency of pain could not be shown. Conclusion Breakdancing must be considered as a potentially high-risk dancing sport. Even with severe injuries, dancers interrupt training only for limited periods of time. Clinical Relevance Breakdance injuries and overuse should not be underestimated. Physicians should be aware of the common risks in this highly acrobatic kind of dancing.
