Towards Automatic Object Detection and Activity Recognition in Indoor Climbing

Rock climbing has propelled from niche sport to mainstream free-time activity and Olympic sport. Moreover, climbing can be studied as an example of a high-stakes perception-action task. However, understanding what constitutes an expert climber is not simple or straightforward. As a dynamic and high-risk activity, climbing requires a precise interplay between cognition, perception, and precise action execution. While prior research has predominantly focused on the movement aspect of climbing (i.e., skeletal posture and individual limb movements), recent studies have also examined the climber’s visual attention and its links to their performance. To associate the climber’s attention with their actions, however, has traditionally required frame-by-frame manual coding of the recorded eye-tracking videos. To overcome this challenge and automatically contextualize the analysis of eye movements in indoor climbing, we present deep learning-driven (YOLOv5) hold detection that facilitates automatic grasp recognition. To demonstrate the framework, we examined the expert climber’s eye movements and egocentric perspective acquired from eye-tracking glasses (SMI and Tobii Glasses 2). Using the framework, we observed that the expert climber’s grasping duration was positively correlated with total fixation duration (r = 0.807) and fixation count (r = 0.864); however, it was negatively correlated with the fixation rate (r = −0.402) and saccade rate (r = −0.344). The findings indicate the moments of cognitive processing and visual search that occurred during decision making and route prospecting. Our work contributes to research on eye–body performance and coordination in high-stakes contexts, and informs the sport science and expands the applications, e.g., in training optimization, injury prevention, and coaching.

Exposure misclassification: an “immortal time” bias in observational studies of training load and injury

Several observational studies of the relationship between training load and injury have found increased risks of injury at low loads. These associations are expected because load is often assessed at the end of the injury follow-up period. As such, athletes who get injured earlier in the follow-up period will have systematically lower loads than athletes who get injured later in the follow-up period. In this commentary, we identify this problem as a type of exposure misclassification occurring from the misalignment of exposure measurement and start of follow-up. This methodological issue has previously been recognized in other areas of epidemiology as “immortal time bias”. We discuss how this bias can be prevented by aligning the measurement of load with the start of follow-up for injury.

Competitive Surfers Training Profile And Injury Prevalence And Patterns: Data From Brazilian National Youth Championship

Competitive Surfers Training Profile And Injury Prevalence And Patterns: Data From Brazilian National Youth Championship

A Single Bout of On-Ice Training Leads to Increased Interlimb Asymmetry in Competitive Youth Hockey Athletes.

Interlimb asymmetry (ILA) refers to an anatomical or physiological imbalance between contralateral limbs, which can influence neuromuscular function. Investigating the influence of neuromuscular fatigue on ILA may be critical for optimizing training programs, injury rehabilitation, and sport-specific performance. The purpose of this study was to determine if a single bout of ice hockey-specific exercise creates or exacerbates lower-limb ILA. Before and after an on-ice training session, 33 youth ice-hockey athletes (14.9 [1.7]y; 11 females) performed 3 repetitions of a maximal vertical countermovement jump (CMJ), an eccentric hamstring contraction, and maximal isometric hip adduction and abduction contractions. Force- and power-related variables were analyzed to determine limb-specific neuromuscular function. The on-ice session reduced maximal isometric hip adduction (left: 7.3% [10.3%]; right: 9.5% [9.6%]) and abduction (left: 4.9% [6.9%]; right: 5.0% [8.1%]) force, but did not impair (P ≥ .10) CMJ performance (jump height, relative peak power, braking duration, and total duration). After the on-ice session, ILA was greater for CMJ propulsive impulse (6.3% [2.9%] vs 5.1% [2.6%]), CMJ braking rate of force development (19.3% [7.6%] vs 15.2% [6.4%]), and peak isometric hip adduction force (6.7% [5.5%] vs 6.1% [4.1%]). In conclusion, hockey-specific exercise leads to increased ILA for multiple force-related metrics, which may be a compensatory mechanism to maintain bilateral task performance when fatigued.

A biomechanics research on drug therapy in the rehabilitation of sports training injuries

In the process of sports training and competition, if sports injury occurs, it not only has a serious impact on the physical and psychological of athletes, but also has a negative impact on the overall training and competition. During the competition, if effective treatment is not obtained, it can have an irreversible impact on athletes’ future participation in sports. Nowadays, many athletes lack knowledge on the prevention and treatment of sports injuries during physical exercise. Therefore, it is urgent to conduct research and analysis on the treatment methods for training injury rehabilitation. In this paper, the visual analogue scale (VAS) and cell landscape analysis technology were used to analyze and compare the therapeutic effects of platelet rich plasma (PRP) injection technology, diclofenac, indomethacin, Qili San and placebo tablets. Focusing on how these drugs promote rehabilitation by affecting mechanical parameters and tissue mechanical properties, it is concluded that PRP injection technique, diclofenac and indomethacin improve the treatment effect of pain after rehabilitation of sports injuries. The number of people who completely recovered with Indomethacin was 4 and that with placebo was 2. The results show that these drugs significantly improve the mechanical properties of the tissue and contribute to the rehabilitation process. This study has further explored the drug treatment of sports injury, explored several drug treatment mechanisms and efficacy and has guiding significance for subsequent drug treatment of sports injury.

Utilize intelligent algorithms to predict medication plans, reduce medication errors, and intelligently adjust the course of treatment based on the patient’s condition. In artificial intelligence healthcare, high-quality online medical services can be created through intelligent technology, providing convenient medical consultation for patients. Result: This article selected 200 patients with musculocutaneous nerve injury caused by aerobics training for grouping experiments. The average diagnostic accuracy of traditional medicine and artificial intelligence medicine were 84.2% and 95.6%, respectively. Conclusion: Artificial intelligence medicine can achieve medical informatization and intelligently analyze patients’ medical information, which helps to improve the accuracy of medical diagnosis for aerobics training injuries.

Athlete Health Implications of Match Injuries in Portuguese Rugby Union.

Our aim was to report time-loss match injuries in Portugal's "Divisão de Honra" (Portuguese first tier) in the 2022/2023 season, focusing on injury incidence, burden, anatomical region, and type, to assess their impact on athletes' health and availability to play. A prospective cohort study was conducted monitoring injuries via an online form filled in by each team's medical department, categorizing player position, as well as injury type, location, and severity. Incidence and burden were calculated per 1000 player-match-hours. The overall injury incidence was 54.4 injuries per 1000 player-match-hours (95% CI 30.3-96.2). Forwards had higher injury incidence than backs. Lower limbs were the most affected locations-29 injuries/1000 h of exposure (95% CI 13.7-52.0). Sprain/ligaments injuries were the most common type of injury (14.4 injuries/1000 h (95% CI 3.7-30.0), followed by muscle injuries (8.1 injuries/1000 h 95% CI 4.9-11.5). Injury incidence was higher than what is reported in amateur competitions and lower than for professionals. Injury severity was similar to that in other studies. Our study suggests a lower injury burden than in other semi-professional and elite leagues. These findings highlight the need for targeted injury prevention strategies in the Portuguese Rugby Union to increase athletes' availability by decreasing injury incidence and/or burden. Further research with broader participation and training injury data is needed.

Advances in Intelligent Sports Based on Triboelectric Nanogenerators

In the realm of intelligent sports, the integration of triboelectric nanogenerators (TENGs) marks a transformative approach toward energy sustainability and more advanced athletic monitoring. By leveraging the principle of triboelectricity, TENGs ingeniously convert mechanical energy from athletes’ movements into electrical energy, which offers a green and efficient power solution for wearable technology. This paper presents an innovative study on the application of TENG technology in sports science, with the results illustrating the potential utility of TENGs in revolutionizing the way we monitor, analyze, and enhance athletic performance. Through the development of self-powered wearables and equipment, TENGs facilitate real-time data collection on physiological and biomechanical parameters, ultimately enabling personalized training adjustments and injury prevention strategies. Our findings underscore the dual benefit of TENGs in promoting environmental sustainability by reducing the overall reliance on traditional energy sources and growing the capabilities of intelligent sports systems. This research contributes to the burgeoning field of nano-energy sports applications while setting the stage for future explorations into the optimization of TENG integration in athletic performance enhancement. Finally, the paper concludes by discussing remaining challenges in this area and opportunities for further research.

Prevalence, severity, and predictors of self-reported depression in ultra-distance runners: An online survey based on 265 athletes.

BackgroundLiterature suggests a high prevalence of mental health disorders among athletes practicing elite and extreme sports. One of the most commonly encountered disorders in this group of individuals is depression. ObjectiveThe aim of this study was to examine the prevalence, severity, and risk factors of symptoms of self-reported depression among ultra-distance runners. MethodsData was collected using an online survey (February to April 2023) and included 265 (age 48.35 ± 10.52 years) adult ultra-runners. The Beck Depression Inventory-II (BDI-II) was used to measure self-reported depression. Additional variables comprised basic sociodemographic information and information regarding training, ultramarathon experience, and previous injury. Descriptive and interferential statistics were performed using JASP Version 0.16.4. ResultsWe found that 21.9 % (n = 58) of ultra-runners suffered from self-reported depression (i.e., BDI-II score ≥ 14) with an average BDI-II score of 22.7 ± 7.1 (moderately severe symptoms). Female ultra-runners had a higher prevalence (30.8 %) of self-reported depression than males (16.2 %, p = .001). Logistic regression revealed that ultra-runners without previous sports injury (p = .01) and those of increasing age (p = .003) had a significantly lower risk of self-reported depression. Similarly, linear regression showed the absence of injury (p < .001) and increasing age (p = .02) resulted in significantly lower BDI-II scores. Training volume in distance and hours per week as well as ultra-running experience did not show any significant association. ConclusionsAffecting more than one-fifth of our collective, depressive symptoms appear to be highly prevalent among ultra-runners. Our findings underline the importance of screening for clinical depression, especially among injured athletes. However, the previously assumed peculiarities of the sport in the area of high training volume do not appear to be a significant factor.

Analysis of Mechanical Damage in Dance Training Under Artificial Intelligence Behavior Constraints

This study focuses on the application of artificial intelligence behavior constraints in the analysis of mechanical injuries in dance training, aiming to accurately analyze and effectively prevent mechanical injuries during dance training through the introduction of artificial intelligence technology. Dance, as a highly dependent art form on physical skills, often comes with a certain risk of mechanical injury during its training process. In this study, we first reviewed the relevant theories of mechanical injuries in dance training and analyzed the inherent relationship between dance movements and mechanical injuries. Subsequently, we utilized artificial intelligence technology to conduct behavior constraint analysis on the dance training process. By constructing a dance action recognition model, we achieved real-time monitoring and evaluation of dance training actions. On this basis, we further utilize the principles of mechanics to quantitatively analyze dance movements and extract key factors that affect mechanical damage. Through in-depth analysis and comparison, this study found that mechanical injuries in dance training are mainly influenced by various factors such as movement standardization, training intensity, and individual differences. We applied the theory of sports biomechanics to study sports dance injuries and analyzed the causes of athlete injuries. By exploring more scientific training methods and means, the correlation coefficients between main joint muscle strength, proprioception, tibialis anterior muscle imbalance response time, and rotational stability were measured to study proprioception training suitable for sports dance, adhering to the principle of gradual progression. In future sports dance rotation training, corresponding training should be carried out according to the characteristics of different rotation steps, providing reference for strengthening leg training and ankle training.

Clinical efficacy of double-bundle and double-tunnel enhanced reconstruction in the treatment of anterior cruciate ligament injury

To explore the clinical efficacy of double beam double tunnel enhanced reconstruction technique in the treatment of knee anterior cruciate ligament(ACL) training injuries. Twenty-nine cases of ACL injury of knee joint from January 2021 to December 2021 were retrospectively analyzed. All the cases were underwent ligament reconstruction surgery. Cases were grouped by surgical technique:there were 14 patients in conventional reconstruction group, including 13 males and 1 female, aged from 22 to 31 years old with an average of (27.07±7.28) years old, autogenous hamstring tendon was used for ligament reconstruction. There were 15 patients in the enhanced reconstruction group, including 13 males and 2 females, aged from 25 to 34 years old with an average of (29.06±4.23) years old, double tunnel ligament reconstruction, the autogenous hamstring muscle was used as the anteromedial bundle, and the posterolateral bundle was replaced by a high-strength line. The difference between knee tibial anterior distance, Lysholm score, International Knee Literature Committee (IKDC) subjective score, Tegner motor level score and visual analog scale (VAS) at 6th and 12th months after the surgery, limb symmetry index (LSI) were recorded at the last follow-up and surgery-related adverse effects during follow-up. All patients were followed up, ranged from 13 to 15 months with an average of (13.7±0.8) months. There were no serious adverse reactions related to surgery during the period. There was no statistical difference between the preoperative general data and the observation index of the two groups (P>0.05). The difference in tibial anterior distance at 6 and 12 months in the enhanced reconstruction group (1.45±0.62) mm and (1.74±0.78) mm which were lower those that in the conventional reconstruction group (2.42±0.60) mm and (2.51±0.63) mm(P<0.05). There was no significant difference in postoperative Lysholm score, Tegner motor level score, IKDC score, VAS, and limb symmetry index at the last follow-up(P>0.05). The enhanced reconstruction technique can more effectively maintain the stability of the knee joint and has no significant effect on the postoperative knee joint function compared with the traditional ligament reconstruction technique. The short-term curative effect is satisfactory, and it is suitable for the group with high sports demand.

Maximizing the performance of badminton athletes through core strength training: Unlocking their full potential using machine learning (ML) modeling

Core strength training plays an essential role in maximizing performance for badminton athletes. The core muscles in the abdominal, back, and hip regions provide stability, enable efficient power transfer between the upper and lower body, and allow for rapid changes in direction - all crucial components for success in badminton. However, optimizing core training requires an understanding of its impact on sport-specific skills. A variety of exercises targeting the abdominal, back, and hip muscles are discussed. Incorporating core strength training into regular regimens can improve athletes' overall strength, endurance, balance, control, and prevent injuries. This study investigates the effects of various core exercises on stability, agility, and power in badminton players. A comprehensive literature review was conducted to explore the biomechanical demands of badminton and how core musculature contributes to movements like serving, smashing, and lunging. Studies assessing the effects of core training programs in related racquet sports were also examined. The results indicate that targeted core exercises significantly improve athletes' stability, agility, and power output. Exercises targeting the abdominal, back, and hip muscles enhance performance capabilities while reducing injury risk. Machine learning (ML) techniques are then applied to further analyze the relationship between core training and athletic performance. An Artificial Neural Network (ANN) is developed using a dataset of athletes' training histories, metrics, and injury profiles. The model predicts enhancements to stability, agility, and strength from optimized core strengthening routines. Validation confirms the network accurately captures the complex interactions between training variables and physical attributes. This integrated approach provides evidence-based guidelines for tailoring individualized training regimens to unleash players' full abilities. ANNs hold promise for analyzing large datasets on athletes' performance metrics, training variables, and injury histories to design personalized training programs. Linear regression analysis confirmed the ANN's accurate predictions. The findings emphasize integrating data-driven core strength training tailored for badminton into comprehensive programs can help optimize physical abilities and elevate performance levels.

Impact of an Integrated Human Performance Support Group: Evaluation of Air Force Special Warfare Candidate Training and Musculoskeletal Injury Outcomes Over Eight Fiscal Years.

The Special Warfare Training Wing and Special Warfare Human Performance Support Group (HPSG; all-co-authors) were established in fiscal year (FY) 2019 to consolidate and oversee all Air Force Special Warfare (AFSPECWAR) training and provide embedded medical and human performance support to candidates with the goal of improving graduation rates and the longevity of the AFSPECWAR operator. The purpose of this manuscript is to assess the impact of the HPSG on AFSPECWAR graduation rates, musculoskeletal injury (MSKI) incidence, and cost. Graduation rates, MSKI incidence (including incidence density and cumulative incidence probability), and MSKI-related health care costs were assessed across all AFSPECWAR training pipelines spanning 8 FYs 2015-22, including Indoctrination, Assessment, and Selection Courses (Selection); Tactical Air Control Party (TACP); Special Tactics (ST), and Guardian Angel (GA). A total of 5,728 distinct candidates were assessed over the time frame. There were significant decreases in attrition when comparing the HPSG era (FY 19-22) with the prior 4-year period for the ST (47% vs. 82% graduates) and TACP (34% vs. 41% graduates) training pipelines. The corresponding Selection (36% graduates) and GA (80% graduates) pipeline attrition rates remained stable. MSKI incidence rates (both incidence density and cumulative incidence probability) overall were not significantly different when comparing the pre-HPSG and HPSG time frames; however, they varied between the two time frames by course. GA candidates had a decrease in MSKI during the apprentice course in the HPSG era compared with the pre-HPSG era (2.4-1.0 cases per 100 trainee weeks; P < .001), which corresponds to a nearly 20% reduction in the cumulative incidence probability (i.e., proportion of trainees injured) after 10 weeks of course. For ST and TACP courses, however, significantly increased incidence of MSKI was observed when comparing the two time frames (P < .001), while for Selection courses, the rates remained stable. A significant reduction in the cost of MSKI-related management (62% total relative value units, 83% total costs) was observed. The impact of the HPSG on attrition, MSKI incidence, and cost-of-care was not consistent across all training pipelines; however, taken together, there were no increases in attrition, and the cost of MSKI management was significantly lower.

Wielokierunkowy wpływ wysiłku fizycznego na układ immunologiczny u sportowców wyczynowych

The extreme physical effort and psychological stress are everyday challenges faced by athletes. The regular training results in adaptation to increasing physical effort. It contributes to changes in various organs and metabolic processes. Intense physical training has been shown to affect numerous body systems including the immune system. The aim of this paper is to present the influence of extreme physical activity on various aspects of immune response. The changes in the immune system of athletes include not only those related to blood leukocytes, but those in connection to respiratory and gut associated lymphoid tissue as well. Moreover, the immune cells play an important role in muscle regeneration after sustaining training injury. The mmunology of physicial activity – mainly extreme physical activity – is a new, not fully recognized yet field of research. The understanding of these interactions facilitates a proper training planning for different groups of athletes.

Incidence and burden of 671 injuries in professional women footballers: time to focus on context-specific injury risk reduction strategies

ABSTRACT This study investigated the extent of injury incidence and burden in a professional women football team of the Scottish Women’s Premier League during two seasons. All injuries causing time-loss or required medical attention were recorded prospectively. A total of 671 injuries, 570 requiring medical attention and 101 causing time-loss were recorded in 41 players. Injuries occurring with National Team resulted in 12% of the club’s international players’ lay-off. Overall injury incidence was 11.1/1000-hours and burden was 368.9 days/1000-hours. Injury incidence (23.9/1000-hours vs 8.2/1000-hours) and burden (1049.8 days/1000-hours vs 215.1 days/1000-hours) were higher for match compared to training. Foremost mechanism of match injury burden was indirect-contact, which was different than the non-contact predominantly observed for training injury burden. Injury incidence, burden and patterns differed between training, match and playing positions. Tailoring injury-risk reduction strategies considering context, circumstances and playing position deserve consideration to enhance player’s injury resilience in professional women footballers.

To investigate the effectiveness of double EndoButton suture fixation Latarjet procedure in the treatment of shoulder anterior dislocation with glenoid bone defect caused by military training injuries. The clinical data of 14 patients with anterior shoulder dislocation with glenoid bone defect due to military training injuries who met the selection criteria and admitted between August 2021 and December 2022 were retrospectively analyzed. All patients were male, the age ranged from 21 to 38 years, with an average of 26.8 years. The time from initial dislocation to operation was 6-15 months, with an average of 10.2 months. Anterior shoulder dislocation occurred 5-12 times, with an average of 8.2 times. All glenoid bone defects were more than 10%, including 5 cases of 10%-15%, 8 cases of 15%-20%, and 1 case of 24%. All patients were treated by double EndoButton suture fixation Latarjet procedure. The operation time and complications were recorded. The shoulder function and pain were evaluated by the American Association for Shoulder and Elbow Surgery (ASES) score, Rowe score, Instability Severity Index Score (ISIS), and visual analogue scale (VAS) score before and after operation. The range of motion of the shoulder was recorded, including forward flexion, 0° external rotation, and abduction 90° external rotation. The position, healing, and resorption of the bone mass were evaluated by three-dimensional CT of shoulder joint after operation. All patients successfully completed the operation, and the operation time was 100-150 minutes, with an average of 119.7 minutes. There was no complications such as infection, vascular and nerve injury. All patients were followed up 12-20 months, with an average of 15.6 months. During the follow-up, 4 patients had bone mass separation, absorption, and recurrent anterior dislocation, and the shoulder joint fear test was positive. Imaging of the remaining patients showed that the bone mass healed well, no anterior dislocation recurrence occurred, and the healing time was 3-7 months (mean, 4.7 months). At last follow-up, the range of motion, ASES score, Rowe score, ISIS score, and VAS score of the patients significantly improved when compared with those before operation ( P<0.05). The effectiveness of double EndoButton suture fixation Latarjet procedure for the treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injury is satisfactory.
