Anaerobic Performance Profiling in Elite Amateur Boxers.

While anaerobic fitness is highly important for the performance in Olympic (amateur) boxing, the relationship between anaerobic performance metrics is poorly understood, and profiling boxers according to their anaerobic capacity is still a challenge. With the current study in elite amateur boxers, we aimed to compare the metabolic and cardiovascular responses to different maximal tests and the intercorrelations between performance indices (peak and mean power, duration of the test, punching frequency) of several all-out tests and their correlation to physiological response metrics (blood lactate and heart rate, HR). Twelve male Olympic boxers performed a battery of tests, including 30 s Wingate cycling and arm cranking, boxing bag punching, steep uphill treadmill running to exhaustion, and progressive treadmill running VO2max test. Performance indices of different anaerobic tests were not closely correlated except for the duration of uphill running with body weight scaled (relative) peak and mean power produced during Wingate cycling test and absolute mean power of both Wingate tests. The number of punches landed on a bag per 30 s was associated only with relative power achieved during Wingate cycling test. HRpeak but not peak lactate response correlated strongly across exercise tasks. Finally, no correlation between the highly developed aerobic and anaerobic capacity, suggests a complex picture of the adaptation in elite amateur boxers.

A Retrospective Analysis of Group-Based Boxing Exercise on Measures of Physical Mobility in Patients With Parkinson Disease.

OBJECTIVES: The purpose of this retrospective study is to further the limited body of evidence regarding the effects of a group-based boxing intervention for those with Parkinson's disease (PD). DESIGN: A retrospective cohort study was performed analyzing data collected on outcome measures at 6-month intervals up to 2 years. Individuals participated in the standardized "Rock Steady Boxing" (RSB) program for up to 24 months. Every 6 months, measures were taken of balance (Fullerton Advanced Balance [FAB] Scale), functional mobility (Timed-Up and Go [TUG]), lower extremity strength (30-second Chair Stand [30CST]), and gait speed (10 Meter Walk Test [10MWT]). METHODS: Statistical significance (P < .05) was determined by a two-tailed t test. Data were collected from RSB-affiliated programs at 4 locations across the southeastern United States. Current and/or past participants in RSB with baseline and at least one subsequent outcome measure were included, resulting in 68 participants (54 male, 14 female, and mean age of 71.2 years ± 8.56 standard deviation). RESULTS: Statistically significant improvements in FAB scale, TUG, and 30CST over time were found at both 6- and 12-month time points. Significant changes continued through 18 months for FAB and 30CST. No significant changes in 10MWT were observed; however, a moderate effect size was observed at the 1-year point. CONCLUSIONS: Participants with PD were able to achieve statistically significant improvements in standard measures of functional mobility, balance, and strength within the timeline of this study. Limitations include the retrospective nature, an inability to monitor adherence, and lack of control over pharmaceutical or other interventions.

Sleepiness in retired male boxers: daytime sleepiness and its relationship with impulsiveness and depression symptomatology in retired professional male boxers.

BACKGROUND: Boxing exposes fighters to head impacts and potential traumatic brain injury (TBI). Though research has explored the neuropsychiatric consequences of contact sports, there is limited research into Excessive Daytime Sleepiness (EDS) and its relationship to other outcomes, such as impulsiveness and depression. Therefore, this study aimed to describe EDS in retired boxers using the Epworth Sleepiness Scale (ESS) and to examine how boxing and sleepiness relate to impulsiveness and depression symptomatology. METHODS: 86 male retired professional boxers from the Professional Fighters Brain Health Study (PFBHS) met the inclusion criteria. Adjusted multivariable models analyzed relationships between professional boxing bouts, EDS (ESS), impulsiveness (Barratt Impulsiveness Scale Version 11 (BIS-11)), and/or depression (Patient Health Questionnaire-9 (PHQ-9)). A causal mediation analysis was performed to assess whether boxing bouts and ESS scores predicted BIS-11 and PHQ-9 scores. RESULTS: Mean age was ∼51 years, fighters averaged ∼36 professional bouts, and ESS mean(SD) was 7.5(5.3). ESS scores were significantly associated with raw BIS-11 (Beta = 1.26, 95%CI = 0.77-1.75, p < 0.001) and ordinal PHQ-9 (OR = 1.20, 95%CI = 1.11-1.31, p < 0.001) scores in adjusted models, and the significant relationship between boxing bouts and BIS-11/PHQ-9 was mediated by ESS. CONCLUSIONS: EDS in retired male professional boxers may be strongly associated with other neuropsychiatric sequelae of TBI (impulsiveness and depression).Sleepiness; sleep; boxing; contact sports; impulsiveness; impulsivity; depression; Epworth sleepiness scale box.

'Knock down the brain': a nonlinear analysis of electroencephalography to study the effects of sub-concussion in boxers.

BACKGROUND AND PURPOSE: Boxing is associated with a high risk of head injuries and increases the likelihood of chronic traumatic encephalopathy. This study explores the effects of sub-concussive impacts on boxers by applying both linear and nonlinear analysis methods to electroencephalogram (EEG) data. METHODS: Twenty-one boxers were selected (mean ± SD, age 28.38 ± 5.5 years; weight 67.55 ± 8.90 kg; years of activity 6.76 ± 5.45; education 14.19 ± 3.08 years) and divided into 'beginner' and 'advanced' groups. The Montreal Cognitive Assessment and the Frontal Assessment Battery were administered; EEG data were collected in both eyes-open (EO) and eyes-closed (EC) conditions during resting states. Analyses of EEG data included normalized power spectral density (nPSD), power law exponent (PLE), detrended fluctuation analysis and multiscale entropy. Statistical analyses were used to compare the groups. RESULTS: Significant differences in nPSD and PLE were observed between the beginner and advanced boxers, with advanced boxers showing decreased mean nPSD and PLE (nPSD 4-7 Hz, p = 0.013; 8-13 Hz, p = 0.003; PLE frontal lobe F3 EC, p = 0.010). Multiscale entropy analysis indicated increased entropy at lower frequencies and decreased entropy at higher frequencies in advanced boxers (F3 EC, p = 0.024; occipital lobe O1 EO, p = 0.029; occipital lobe O2 EO, p = 0.036). These changes are similar to those seen in Alzheimer's disease. CONCLUSION: Nonlinear analysis of EEG data shows potential as a neurophysiological biomarker for detecting the asymptomatic phase of chronic traumatic encephalopathy in boxers. This methodology could help monitor athletes' health and reduce the risk of future neurological injuries in sports.

Innovative boxing training program outperforms the traditional scapular stabilization training program in post-stroke patients.

Facilitating the restoration of upper limb functionality is a key objective of stroke rehabilitation. This study aimed to compare the effects of boxing and scapular stabilization training on scapular mobility, balance angle, muscle strength, motor function, and satisfaction in hemiparetic patients. A total of sixty patients were randomly assigned to one of three groups: the boxing group (BG; n = 20), the scapular stabilization group (SSG; n = 20), or the control group (CG; n = 20) which received no treatment at all. Each treatment group participated in three sessions per week for a total of eight weeks. The scapular mobility, balance angle (SBA), muscle strength, upper extremity motor functions (Manual Function Test-MFT), and treatment satisfaction were evaluated. The BG group showed greater improvements in the SBA (F = 59,951; p = 0.000; η2 = 0.682), mobility-frontal plane (F = 7998; p = 0.000; η2 = 0.222), mobility-sagittal plane (F = 91,632; p = 0.000; η2 = 0.766), and mobility-transverse plane (F = 48,713; p = 0.000; η2 = 0.635) than did the CG group. BG strengthened the serratus anterior (F = 42,227; p = 0.000; η2 = 0.601), while SSG strengthened the infraspinatus (F = 31,772; p = 0.000; η2 = 0.532) more than did CG. Compared with those in the SSG, supraspinatus (F = 52,589; p = 0.000; η2 = 0.653), upper trapezius (F = 42,890; p = 0.000; η2 = 0.605), anterior deltoideus (F = 30,844; p = 0.000; η2 = 0.524), latissimus dorsi (F = 84,345; p = 0.000; η2 = 0.751), MFTs (F = 52,363; p = 0.000; η2 = 0.652) and satisfaction (p = 0.008) were greater in the BG. Both approaches had a beneficial impact on the recovery process. However, boxing training was more effective than scapular stabilization training for several parameters. Clinical Trial Number: NCT05568173 date 5/10/2022.

The effect of optimal load training on punching ability in elite female boxers.

Optimal load training is a method of training that aims to maximize power output. This is achieved by arranging optimal loads (optimal ratios of load intensity and load volume) during strength training. The fixed load intensity and number of repetitions employed in traditional strength training. The present study will investigate the applicability of these two load arrangements to female elite boxers. Twenty-four elite female boxers were divided into three groups [optimal load (OL = 8), traditional load (TL = 8) and control group (CG = 8)]. The six-week intervention consisted of strength training with different loading arrangements. The punching ability and strength were tested before and after the intervention. We found that optimal load training enhances a boxer's punching ability and economy, which aligns with the demands of boxing and is suitable for high-level athletes, whose strength training loads require a more individualised and targeted approach.

Enhanced boxing punch impact with silicone cushioning.

Introduction: Elastic cushioning materials protect human tissue from injury by absorbing impact energy and delaying its transfer. However, the potential compromise in force delivery to the hitting target remains unknown. Methods: To examine if silicone cushioning compromises punch force delivery to a hitting target, a double-blind crossover trial with 12 elite boxers was conducted following material tests. Each boxer delivered five maximal punches under two conditions: silicone-hand wrapping and gauze-hand wrapping, in counterbalanced order, with a 3-day interval between sessions. Force distribution along the Z-axis indicated the punch's intended direction, while forces along the X and Y axes represented force dissipation toward unwanted direction. Results: The material tests (based on ASTM International, West Conshohocken, PA, USA) demonstrated substantially higher compression to disruption for silicone than gauze of similar thickness. During the punching trials, the silicon-based hand wrapping exhibited slightly higher total force production (436 ± 33 N vs. 372 ± 12 N, p < 0.001) than the gauze-based hand wrapping. Moreover, force wastage, calculated as the sum of forces along the X and Y axes vs. the total force produced in percentage, was notably lower for silicone material (2.0% wastage) compared to gauze (3.8% wastage) (p < 0.001). The use of silicone materials lengthened the contact time between the punching fist and the hitting target from 35 ms to 50 ms (p < 0.001). Conclusion: The elastic cushion does not compromise the force delivery of the boxing glove to the hitting target. Instead, it appears to allow for additional maneuvering time for alignment during the fist-target contact with higher impact.

Accuracy of Instrumented Mouthguards During Direct Jaw Impacts Seen in Boxing.

PURPOSE: Measuring head kinematics data is important to understand and develop methods and standards to mitigate head injuries in contact sports. Instrumented mouthguards (iMGs) have been developed to address coupling issues with previous sensors. Although validated with anthropomorphic test devices (ATDs), there is limited post-mortem human subjects (PMHS) data which provides more accurate soft tissue responses. This study evaluated two iMGs (Prevent Biometrics (PRE) and Diversified Technical Systems (DTS) in response to direct jaw impacts. METHODS: Three unembalmed male cadaver heads were properly fitted with two different boil-and-bite iMGs and impacted with hook (4 m/s) and uppercut (3 m/s) punches. A reference sensor (REF) was rigidly attached to the base of the skull, impact kinematics were transformed to the head center of gravity and linear and angular kinematic data were compared to the iMGs including Peak Linear Acceleration, Peak Angular Acceleration, Peak Angular Velocity, Head Injury Criterion (HIC), HIC duration, and Brain Injury Criterion. RESULTS: Compared to the REF sensor, the PRE iMG underpredicted most of the kinematic data with slopes of the validation regression line between 0.72 and 1.04 and the DTS overpredicted all the kinematic data with slopes of the regression line between 1.4 and 8.7. CONCLUSION: While the PRE iMG was closer to the REF sensor compared to the DTS iMG, the results did not support the previous findings reported with use of ATDs. Hence, our study highlights the benefits of using PMHS for validating the accuracy of iMGs since they closely mimic the human body compared to any ATD's mandible.

Relationship between visual ability assessment and punch performance in competition in male amateur boxers.

Sport visual ability plays an important role in the performance of elite athletes in competition. However, its relationship with boxers' performance has not been fully understood. This study investigated the relationship between sports visual abilities and in-competition punching performance in 26 highly trained male amateur boxers. Ten visual abilities of the boxers were tested using the Senaptec Sensory Station (Senaptec, Beaverton, OR, United States), including Visual Clarity (VC), Contrast Sensitivity (CS), Depth Perception (DP), Near Far Quickness (NFQ), Target Capture (TC), Perception Span (PS), Multiple Object Tracking (MOT), Eye-Hand Coordination (EHC), Go/No Go (GNG), and Reaction Time (RT). Performance analyses were conducted on national boxing championships conducted by the boxers to analyze their punching accuracy. Correlation and regression analyses showed that punch performance %Hit was very strong correlated with DP, EHC, GNG, and RT, and showed a strong correlation with VC, CS, and PS. %Hit was moderate correlated with MOT, while there was no correlation with NFQ and TC. In addition, RT, EHC, and DP are important visual ability variables for boxers. The results of this study indicate that there is an overall relationship between sports visual ability and boxing performance, but there is also a specific relationship between variables in visual ability and boxing performance, especially faster reaction times, better processing of visual information, and decision-making abilities, and the ability to accurately recognize the distance and position of an opponent and their punches are essential for enhancing boxing performance. Further studies are needed to investigate the relationship between sport visual ability and more comprehensive performance in boxers, and the possibility of enhancing performance through specific visual training.

Phase Angle and Body Composition as Predictors of Fitness and Athletic Performance in Adolescent Boxers.

BACKGROUND: Phase angle (PhA) is an indicator of cellular health, function, and integrity. PhA has been considered an indicator of nutritional and health status, but it is uncertain whether it could be used as a fitness or athletic performance indicator. OBJECTIVE: To analyze the relationship between PhA and the fitness and athletic performance of adolescent boxers and to know whether this association is independent of body composition. METHODS: Thirty-seven trained youth boxers (15-18 y old) participated in the study. Participants underwent anthropometry and bioelectrical impedance assessments. The following tests were conducted: Fitness-Gram battery; speed, agility, and quickness; ball throws; punch impact force; bench press maximal strength; and vertical and horizontal jumps. Linear regression models were estimated and adjusted by covariates. RESULTS: The PhA was related to upper-limb strength. Nevertheless, in linear regression models, after adjusting models by body composition, only PhA remained as a predictor of relative maximal strength. The PhA was not a predictor of speed, agility, and quickness; cardiorespiratory fitness; or lower-limb power, in which adiposity was the main predictor of fitness. CONCLUSIONS: In adolescent boxers, PhA can predict upper-limb maximal strength independently of bioelectrical impedance analysis premises. However, compared with mucle mass, PhA is not a better predictor of upper-limb maximal strength.

Emerging athletes' career transitions in professional sport: an existential multi-case perspective.

Introduction: This article examines athletes preparing for, transitioning into, or going through the developmental stages of a professional sports career, referred to as the emerging athlete career transition. This transition includes events such as selections, Junior-to-Senior promotions, contracting, migration, and early exits. The article presents the collective findings of a multi-case study in three professional sports: rugby league, basketball, and boxing. Method: Consistent with pragmatic qualitative research methodology, a stratified data set was collected and analysed, incorporating researcher-practitioner fieldwork, interviews, documents and artefacts for these cases. This article explores unique events and the demographic and cultural implications of navigating emergent transitions along professional sporting pathways in New Zealand. Findings: These findings highlight the importance of building self-efficacy as a pre-condition for coping through preparation and experience. Recommendations: Recommendations include fostering collaborative cultures and authentic support relationships to facilitate better coping alongside athletic and personal development in these high-pressured environments. Furthermore, understanding existential perspectives of meaning, choice, and responsibility provides insights for developing the resources that allow emerging athletes to thrive in life beyond sport.

Reliability of Three Landmine-Punch-Throw Variations and Their Load-Velocity Relationships Performed With the Dominant and Nondominant Hands.

PURPOSE: This study assessed the reliability and load-velocity profiles of 3 different landmine-punch-throw variations (seated without trunk rotation, seated with trunk rotation, and standing whole body) with different loads (20, 22.5, and 25.0 kg), all with the dominant hand and nondominant hand. METHODS: In a quasi-randomized order, 14 boxers (24.1 [4.3] y, 72.6 [10.1] kg) performed 3 repetitions of each variation with their dominant hand and their nondominant hand, with maximal effort and 3 minutes of interset rest. Peak velocity was measured via the GymAware Power Tool (Kinetic Performance Technologies). The interclass correlation coefficients and their 95% CIs were used to determine the intrasession reliability of each variation × load × hand combination. Additionally, a 2 (hand) × 3 (variation) repeated-measures analysis of variance assessed the load-velocity profile slope, and a 3 (variation) × 2 (hand) × 3 (load) repeated-measures analysis of variance assessed the peak velocity of each variation. RESULTS: Most variations were highly reliable (intraclass correlation coefficient > .91), with the nondominant hand being as reliable or more reliable than the dominant hand. Very strong linear relationships were observed for the group average for each variation (R2 ≥ .96). However, there was no variation × hand interaction for the slope, and there was no main effect for variation or hand. Additionally, there was no interaction for the peak velocity, but there were main effects for variation, hand, and load (P < .01). CONCLUSION: Each variation was reliable and can be used to create upper-body ballistic unilateral load-velocity profiles. However, as with other research on load-velocity profile, individual data allowed for more accurate profiling than group average data.

Can boxing relieve symptoms of Parkinson's disease and improve quality of life? A qualitative study of the experiences of participants attending the Danish Parkinson boxing concept.

PURPOSE: To explore how people with Parkinson's (PwP) experience the impact of attending Parkinson Boxing (PB) on their symptoms and quality of life. METHODS: The authors NMAY and PeB conducted participant observations of four PB sessions and eight semi-structured interviews with PwP who participated in PB in Denmark. The empirical material was systematically analyzed using thematic analysis. RESULTS: Four main themes arose. The participants experience a sense of community from being part of a group where they share the same diagnosis. They described various bodily experiences related to their physical and cognitive functioning and well-being, as well as emotional experiences including feelings of joy, gratitude, and mental well-being. They are motivated to participate in the training sessions, and participation further motivates them to retain their exercise practice. CONCLUSIONS: The experienced impact of participating in PB relates to physical relief of symptoms and improved functioning in everyday life, as well as a mental lift, energy, and joy during and after training sessions. Participants described being motivated to attend PB and to continue their training practice. Thus, PB entails experiences of relief of symptoms and presumably improved quality of life for the participants.

Physical activity is an effective complementary treatment to experience improvement in health and well-being for people affected by Parkinson's disease.The Danish concept, Parkinson Boxing, inspired by the concept Rock Steady Boxing from USA, shows promise to relieve symptoms, improve mental and physical well-being and create social relationships.The motivation to engage in physical activity increases when exercising in a diagnosis-specific group as Parkinson Boxing where participants have a shared understanding of each other's challenges and simultaneously achieve social relationships.We recommend that rehabilitation professionals use diagnosis-specific group-based interventions which in addition to physical benefits creates basis for a sense of community, mental well-being and motivation to maintain physical activity among participants.

Care of The Older Fighter: Position Statement of the Association of Ringside Physicians.

Older Fighters are defined as combat sports athletes older than 35 years, based on heightened medical risks and historical classification. Age-related changes to the neurological, cardiopulmonary, endocrinological, thermoregulatory, osmoregulatory, and musculoskeletal systems increase these athletes' risks for injury and may prolong their recovery. These age-related risks warrant special considerations for competition, licensure, prefight medical clearance, in-fight supervision, post-fight examination, and counseling regarding training practices and retirement from combat sports. Neurological considerations include increased risk of intracranial lesions, intracranial hemorrhage, and sequelae from traumatic brain injury (TBI), warranting more comprehensive neurological evaluation and neuroimaging. Increased risk of myocardial ischemia and infarction warrant careful assessment of cardiac risk factors and scrutiny of cardiovascular fitness. Older fighters may take longer time to recover from musculoskeletal injury; post-injury clearance should be individualized.

Degenerative changes of the wrist in mixed martial arts and boxing based on the three column theory.

OBJECTIVE: Mixed Martial Arts (MMA) is a relatively young combat sport. In contrast to classic boxing, MMA combines techniques of grappling and striking. However, characteristic long-term effects of MMA on the wrist are discussed controversially. Aim of this study was to elucidate characteristic degenerative changes of the wrist from MMA fighters in comparison to classic boxers. METHODS: In this study, eleven professional MMA fighters and ten professional boxers with chronic wrist pain were examined and compared. Age, weight, number of fights and weekly hours of training were recorded. Wrist and hand of each fighter were examined using a 3T-MR scanner. Degenerations of the radial, central and ulnar column were analyzed according to Navarro's three-column theory and degenerative changes were categorized based on the classification of Fredericson. RESULTS: There was no significant difference of age, weight and number of fights between MMA fighters and boxers (p > 0.15). However, MMA fighters practiced significantly more hours per week (19.5 (MMA) vs. 8.5 (boxing) hours/week, p < 0.001). No significant associations were found between different training times per Week in terms of degenerative changes of the wrist in MMA and boxing based on the three column theory. The comparison of degenerative changes in the columns between MMA and boxing showed no significant differences. The MRI showed a significantly higher degeneration in the radial column compared to the central column among MMA fighters for ligaments (p = 0.01) and bones (p = 0.03). CONCLUSION: Due to different fighting techniques, different physical traumas, including falls, pattern of degenerations of the wrist between MMA fighters and boxers are different. MMA fighters suffer of a highly degenerative radial column and boxers suffer of a homogeneous degeneration of all three columns.

The effects of nonverbal pride and skill on judgements of victory and social influence: a boxing study.

Displaying nonverbal pride after a boxing match leads to judgements of success. However, it is not clear the extent to which this effect generalises nor whether it can override competing information. An experimental design had 214 participants watch two boxing clips that were manipulated so that one was evenly matched and the other had a fighter with an advantage (i.e. demonstrating more skill). Nonverbal behaviour at the completion of the fight varied between fighters (pride versus neutral). When the fight was evenly matched, the fighters displaying nonverbal pride were judged as winning the fight, but the fighter did not garner increased social influence. In contrast, when fighters demonstrated superior skill, the more skilled fighters who displayed neutral postures rather than the less-skilled ones displaying pride were judged as winning the fight, and the skilled fighters garnered increased social influence. These results suggest that in a boxing context, a pride bias works in evenly matched scenarios, but when differences in skill are more clearly present, a skill bias is more pronounced and leads to more social influence. Furthermore, perceptions of skill were associated with judgments of victory across stimuli, suggesting the importance of skill perceptions in such judgments.

Effect of Boxing Exercises on the Functional Ability and Quality of Life of Individuals with Parkinson's Disease: A Systematic Review.

Parkinson's disease (PD) is a neurological disorder caused by the loss of dopamine-producing cells in the substantia nigra and characterized by motor and non-motor symptoms. Boxing is a type of complementary therapy to improve symptoms in PD. The purpose of the present study was to examine the effect of boxing training on the functionality and quality of life of patients with PD. The literature search was performed on PubMed, Scopus, PEDro, Cochrane Library, and Google Scholar search engines. The PEDro scale was used to assess the methodological quality of the studies. This systematic review included three studies that examined disease severity, mobility, physical activity, balance, and quality of life. According to the PEDro scale criteria, the three articles included were of high methodological quality. Statistically significant improvements after the implementation of boxing training was shown for balance and quality of life in contrast to the other variables. Boxing training intervention programs had a positive effect on balance and quality of life in patients with PD; however, the results are conflicting regarding certain functionality variables. Therefore, it is necessary to conduct further research to examine the effectiveness of boxing training on the functionality and quality of life of patients with Parkinson's disease.

El artículo que se ofrece tiene como objetivo socializar resultados de la investigación realizada sobre el desentrenamiento deportivo en el boxeo potenciado con el equino-interacción-profiláctica. De manera conclusiva, los aportes teórico y práctico demostraron el cumplimiento del objetivo de la investigación y la solución del problema científico.

A preparação do boxeador implica em mudanças e adaptações fisiológicas para garantir as cargas físicas, psicológicas e sociais às quais o boxeador foi submetido. Ao final dessa etapa, surge o destreinamento esportivo, cuja natureza é eminentemente pedagógica e consiste em desinstalar os componentes que garantiram o acúmulo de cargas durante sua etapa como boxeador ativo, até atingir os níveis de um praticante normal sistemático de Cultura Física. O objetivo deste trabalho consistiu em projetar uma estratégia pedagógica baseada em um modelo semelhante de destreinamento aprimorado com a interação equino-profilática, baseada no uso de exercícios com cavalos como elemento de mudança. Os métodos e técnicas empíricos utilizados foram a observação de sessões esportivas, a análise de documentos, pesquisas com ex-pugilistas, treinadores, médicos esportivos, oficiais e especialistas selecionados, bem como workshops de opinião crítica e socialização entre treinadores de boxe. Como resultado, foi obtido um modelo pedagógico do qual derivou uma estratégia. Essas contribuições foram confirmadas por meio da aplicação parcial da estratégia em uma equipe esportiva em Majibacoa, Las Tunas, e sua viabilidade de generalização foi demonstrada. O objetivo deste artigo é socializar os resultados da pesquisa realizada sobre o destreinamento esportivo no boxe, aprimorado com a interação equino-profilática. Em conclusão, as contribuições teóricas e práticas demonstraram o cumprimento do objetivo da pesquisa e a solução do problema científico.

The preparation of the boxer entails physiological changes and adaptations to guarantee the physical, psychological and social loads to which its practitioners have been subjected. Once this stage is completed, sports detraining appears, the nature of which is eminently pedagogical and consists of uninstalling the components that guaranteed the accumulation of loads during his time as an active boxer, until reaching the levels of a normal systematic practitioner of Physical Culture. The objective of this work was to design a pedagogical strategy based on a model of the same nature for detraining enhanced with equine-interaction-prophylactics, based on the use of exercises with horses as an element of change. Observation of sports sessions, document analysis, a survey of former boxers, coaches, sports doctors, officials and selected experts, as well as critical opinion and socialization workshops among boxing coaches, were used as empirical methods and techniques. As results, a pedagogical model was obtained from which a strategy was derived. These contributions were verified through the partial application of the strategy in a sports complex in Majibacoa, Las Tunas and its feasibility to be generalized was demonstrated. The article offered aims to socialize results of the research carried out on sports detraining in boxing enhanced with equine-interaction-prophylaxis. Conclusively, the theoretical and practical contributions demonstrated the fulfillment of the research objective and the solution of the scientific problem.

Application of immersive virtual reality in the training of wheelchair boxers: evaluation of exercise intensity and users experience additional load- a pilot exploratory study.

BACKGROUND: Over the last few years, there has been a growing interest in workout apps and active virtual reality video games (AVRGs), which provide entertainment and enable users to undertake various forms of physical activity (PA) at home. Presumably, these types of exercises can be particularly useful for people with physical disabilities, who experience problems with access to sports and leisure facilities due to architectural and communication barriers. However, it is interesting whether the intensity of PA in VR is high enough to provide users with health benefits, as it is mainly based on arm movements. OBJECTIVE: The main aim of the study was to evaluate the intensity of physical exercise of wheelchair boxers during a boxing training session using the FitXR app in immersive VR in light of health-related PA recommendations. The effect of Velcro-fastened hand-held weights (HHWs) on the intensity of PA undertaken by people in VR was also examined, and the attractiveness of virtual exercise were assessed in the opinion of users. METHODS: PA intensity was evaluated using a heart rate monitor based on the percentage of maximal heart rate (% HRmax) and the Borg's rating of perceived exertion (RPE 6-20). The attractiveness perceived during exercise by users were evaluated using the Physical Activity Enjoyment Scale (PACES 1-7 scale). RESULTS: The study shows that the exercise intensity of the athletes during wheelchair boxing training in VR is at a beneficial moderate level for health (HRave=68.98% HRmax). The use of HHWs (0.5 kg) does not significantly increase the PA intensity of the individuals during virtual exercise. Users with disabilities highly rated the attractiveness (6.32 ± 0.79 points) of PA during virtual boxing training. CONCLUSIONS: Boxing exercises in VR can be an attractive and health-related form of PA for wheelchair boxers and a supplement to their conventional training.

Boxing behavior recognition based on artificial intelligence convolutional neural network with sports psychology assistant.

The purpose of this study is to deeply understand the psychological state of boxers before the competition, and explore an efficient boxing action classification and recognition model supported by artificial intelligence (AI) technology through these psychological characteristics. Firstly, this study systematically measures the key psychological dimensions of boxers, such as anxiety level, self-confidence, team identity, and opponent attitude, through psychological scale survey to obtain detailed psychological data. Then, based on these data, this study innovatively constructs a boxing action classification and recognition model based on BERT fusion 3D-ResNet, which not only comprehensively considers psychological information, but also carefully considers action characteristics to improve the classification accuracy of boxing actions. The performance evaluation shows that the model proposed in this study is significantly superior to the traditional model in terms of loss value, accuracy and F1 value, and the accuracy reaches 96.86%. Therefore, through the comprehensive application of psychology and deep learning, this study successfully constructs a boxing action classification and recognition model that can fully understand the psychological state of boxers, which provides strong support for the psychological training and action classification of boxers.
