Resumen
Introduction: One of the limiting factors in the quality of life of seniors is the increased risk of falls. We come up with a new type of exercise, modified parkour for older adults. Objective: The purpose of the study was to determine the effect of the Parkour concept on functional mobility in older adults. Patients and Methods: Twenty older adults without cognitive or neurological deficits (> 26 points in the MoCa test) completed a 10-week exercise program. The program included the practice of overcoming obstacles of various shapes and sizes and the practice of fall techniques under the guidance of an instructor. The level of functional mobility was evaluated using the Timed Up and Go test (TUG 1), the Timed Up and Go test Cognitive, and the Timed Up and Go test manual (TUG 3) and functional reach test (Reach) before and after completing the exercise program. Results: Although participants in the parkour intervention program showed good results in the reach test before starting it, they were able to improve significantly. The effect of the parkour concept is not statistically significant for the functional mobility measured by the TUG tests. The difference is small by Cohen’s effect size (d = 0.22 and d=0.26). There was a slight improvement in the functional mobility test without another task (TUG1) and the modified test with another movement task (TUG3). There was no significant change in the modified cognitive test (TUG2). Conclusion: Modified parkour is a new activity that requires more scientific research. For this age group, we consider a positive improvement in any part of physical fitness.

Resumen
Background: Parkour is a modern sport known for daring jumps and moves in urban environments that require exceptional motor skills and various sports-specific techniques. Although it is increasingly popular among children and adolescents, training routines in youth Parkour are still rather driven by personal beliefs and experience of coaches than by evidence.
Purpose: This study aims to analyze basic motor skills and physical fitness of youth Parkour athletes compared to team sports athletes.
Study design: Cross-sectional study with matched-pair analysis.
Methods: Seventeen youth Parkour (12.50 ± 1.80 years) and seventeen team sports athletes (11.90 ± 1.70 years), matched for height and weight, participated in this study. Tests included static (single-leg postural sway = PS) and dynamic balance (Y-Balance test = YBT), jumping (countermovement jump = CMJ, drop jump = DJ, side-hop = SH), muscle strength (planks, pull-ups = PU) and basic gymnastics skills (bridging = BG, handstand = HS, cartwheel = CW).
Results: The Parkour group performed significantly better in the CMJ (p = 0.014), the anterior direction of the YBT (p < 0.001), cartwheel performance (p = 0.019), and pull-ups (p = 0.029) when compared to the team-sports group. Moderate but non-significant differences were observed in PS for the dominant (p = 0.12) and non-dominant leg (p = 0.14) as well as in SH (p = 0.06). No further significant differences were observed.
Conclusion: Children practicing Parkour demonstrated superior performances in certain parameters of motor skills and physical fitness compared to team sports athletes. The findings suggest that Parkour may contribute positively to children's overall physical development. However, more intervention studies with a prospective study design are needed for further recommendations.

Resumen
Background: Assistive devices facilitate daily activities and recovery, and are essential for nonweightbearing ambulation after orthopaedic foot or ankle surgery.
This study aimed to compare the usability of forearm crutches (FCs) and hands-free single crutches (HFSCs) during the early postoperative recovery phase in terms of their effects on mobility, speed, safety, range, endurance, personal preference, and quality of life. Methods: This prospective randomized crossover study included 35 participants. Assessments included the 36-Item Short-Form Survey, Short Musculoskeletal Function Assessment Questionnaire, and European Foot and Ankle Society Score administered preoperatively and at 2 follow-up examinations. Patients were assigned to either device (FC or HFSC) for the first 3weeks after surgery. The primary outcome was number of stumble events (SEs) during standardized mobility tests. For secondary outcomes (including mobility, speed, and range), patients completed clinical tests such as the 6-minute walk test, stair-climbing test, 10-m walk test, and indoor and outdoor parkour activities. Following the clinical tests, the patients provided qualitative feedback, including personal preference and overall device usage. After switching the devices, the tests were repeated at 6weeks postoperatively.
Results: Although FCs performed better in most mobility tests, patients favored HFSCs because of enhanced comfort and lower perceived exertion. Despite the physical advantages of FCs, patients tended to prefer HFSCs owing to their ergonomic benefits. The quality of life and physical function scores for both devices declined after surgery, reflecting a typical postoperative recovery phase. Younger and male patients generally performed better with HFSCs, whereas female, older, and overweight patients faced more challenges.
Conclusion: FCs outperform HFSCs with respect to mobility, but patients prefer HFSCs due to comfort and reduced exertion although the clinical significance of these perceived differences remains uncertain. This underscores the need for personalized device recommendations to improve postoperative outcomes. This study highlights the complexity of device selection based on individual patient needs and preferences.

Resumen
The positive impact of physical activity on cognitive functions is well established and varies by exercise type, with open‐skill sports—activities involving high uncertainty—offering distinct advantages. Although team sports are traditionally considered open‐skill activities, parkour provides a dynamic and varied environment. This study compared the effects of indoor team sports (consistent environment) and parkour (varied environments) on cognitive functions. Forty healthy young adults (mean age: 21.5 ± 3 years) were divided into a team sports group (TS, n = 19) and a parkour group (PK, n = 21). Both groups trained twice a week for 4 weeks, with sessions lasting 2 hours each. Cognitive performance was assessed pre‐ and posttraining using the Trail Making Test (TMT), Letter Cancellation Test (LCT), Change Blindness Test (CB), visual memory tests, and short‐ and long‐term memory recall. The PK group significantly improved in TMT and CB tests (p < 0.001), whereas the TS group showed no significant changes (p > 0.05). Both groups improved similarly in the LCT and working memory tests (p < 0.001). However, the PK group outperformed the TS group in long‐term memory tasks (p < 0.001). These findings suggest that parkour's exploratory nature enhances observation skills, visuospatial attention, and long‐term memory more effectively than indoor team sports. Training in diverse environments appears to yield greater benefits for visual and cognitive capacities than practice in static settings.

Resumen
Transcranial direct current stimulation (tDCS) is used to modulate brain function, and can modulate motor and postural control. While the acute effect of tDCS is well documented on patients, little is still known whether tDCS can alter the motor control of healthy trained participants. This study aimed to assess the acute effect of tDCS on postural control of parkour practitioners, known for their good balance abilities and their neuromuscular specificities that make them good candidates for tDCS intervention. Eighteen parkour practitioners were tested on three occasions in the laboratory for each stimulation condition (2 mA; 20 minutes)–primary motor cortex (M1), dorsolateral prefrontal cortex (dlPFC) and sham (placebo). Postural control was evaluated PRE and POST each stimulation by measuring Center of Pressure (CoP) displacements on a force platform during static conditions (bipedal and unipedal stance). Following M1 stimulation, significant decreases were observed in CoP area in unipedal (from 607.1 ± 297.9 mm² to 451.1 ± 173.9 mm², P = 0.003) and bipedal (from 157.5 ± 74.1 mm² to 117.6 ± 59.8 mm² P<0.001) stances. As well, the CoP total length was significantly reduced in bipedal (from 3416.8 ± 295.4 mm to 3280.6 ± 306.2 mm, P = 0.005) as well as in unipedal stance (from 4259.6 ± 398.4 mm to 3846.5 ± 468.9 mm, P<0.001), only after M1 stimulation. Relative pre-post changes observed after M1 stimulation were negatively correlated to experience in parkour only after unipedal stance (r = 0.715, P<0.001), meaning that the more participants were trained the less tDCS was effective. No significant changes were noticed after sham and dlPFC stimulation. These results suggested that the modulation of gait performance in athletes following an acute intervention of tDCS is specific to the targeted brain region, and that postures with reduced base of support (such as unipedal stance) were more sensitive to tDCS.

Resumen
The exponential growth in engagement with extreme sports in recent decades has surpassed our understanding of the perceptions and personal experiences of those individuals who participated. This research explores the relationship between self-efficacy, perceived enjoyment, perceived risk, attitude toward behavior, and continuance intention within the framework of the theory of planned behavior. The study collected data from 193 parkour enthusiasts who associated with Chinese amateur parkour clubs. Hypotheses were verified using structural equation modeling using AMOS 26.0. The results demonstrate notable associations across all categories, however, the hypothesis that perceived risk will influence attitude toward behavior was not supported. The study concludes with discussions on the implications for scholars and practitioners and suggestions for future research.

Resumen
In recent years, the number of practitioners of disciplines such as parkour, break dance or calisthenics (freestyle or street workout) has increased. These disciplines share common characteristics, such as an unregulated street origin and a focus on acrobatics. This study aimed to analyze the state of scientific publications related to these acrobatic street sports. A bibliometric analysis was conducted, applying traditional bibliometric laws to scientific documentation found in journals indexed in WoS and Scopus. Data processing and visualization were performed using Bibliometrix and Excel. A total of 199 articles published between 1984 and 2024 were identified, indicating exponential growth. Among these, 139 papers were related to parkour, 48 to breakdance, and 12 to street workout. A review of 158 journals revealed that they contained related publications, although their distribution did not conform to Bradford’s model, showig only two areas. Among 417 authors identified, 22 were deemed prolific and 12 prominent. France emerged as the most prolific country, followed by the USA. The 553 author keywords were categorized into three groups, each associated with one of the sports. The 26 most cited papers were selected as relevant, demonstrating a correlation between the increase in publications and the popularization of these sports, largely due to television exposure. The "International Journal of Sport Policy and Politics” emerged as the most prolific journal. The most relevant authors identified in each sport were Signey Grosprêtre (parkour); Max Daniel Kauther and Christian Wedemeyer (breakdance); and Javier Sanchez-Martinez (street workout)

Resumen
Perilunate dislocations are uncommon high energy injuries. The combination of fractures resulting in a trans-styloid, trans-scaphoid, and trans-triquetral perilunate fracture dislocation is extremely rare. We describe a 20 year old male who suffered this injury after a fall from height while parkouring. He underwent open reduction and internal fixation with ligamentous repair and carpal tunnel decompression. After 3 months, he was noted to have a radiographic evidence of scapholunate dissociation and he returned to the operative room for definitive fixation. Despite this complication, the final functional outcome 6 months after the second surgery was satisfying.

Resumen
This study aimed to describe frequent parkour practitioners' training habits, training motives and goals, and perceived performance factors of practitioners from different countries and continents. An ad hoc questionnaire (PARK-Q) was developed in four languages by the research group and validated by active experts with 12-18 years of experience practising and coaching parkour. The PARK-Q is a multidimensional questionnaire that explores demographics, habits, goals, motivation and perceived performance factors from the practitioner's perspective. The PARK-Q presented overall great internal consistency (Cronbach's α=.902) and was answered by one hundred and forty-one parkour practitioners (n=141, 26.2±5.0 years old) from 15 countries and four continents. Parkour could still be considered a masculine action sport with a low level of federated participation, mostly practised outdoors, with friends, in an unstructured way, and learnt freely: with friends, autodidact, etc. Parkour practitioners' motivation mainly comes from within and could be considered Intrinsic Motivation. To parkour practitioners, Precision, Environmental adaptability, and Movement techniques may be considered the most important performance factors, whereas Flip repertoire, Suffering capacity, and Keeping yourself distracted are the least important. Thus, new measuring instruments or assessments that align better with the discipline should be explored, considering the performance factors perceived by international parkour practitioners.

Resumen
Gymnastics encompasses various disciplines, including artistic gymnastics, rhythmic gymnastics, trampoline gymnastics, acrobatics, aerobic gymnastics, parkour, and gymnastics for all. While there are many differences in characteristics, movement execution, and equipment, all disciplines involve brief and high-intensity movements. Athletes achieve extreme ranges of motion and generate and absorb significant forces while performing gymnastic elements. Consequently, gymnasts are prone to numerous injuries, with frequencies ranging from 0.5 to 9.4 injuries per 1000 hours of athlete exposure. The most common types of gymnastics injuries are sprains and strains. In females, lower limb injuries prevail, whereas males predominantly experience upper limb injuries. Specifically, the ankle, knee, and foot are frequent sites of injury in the lower limb, while the shoulder joint, wrist, and elbow are commonly affected in the upper limb. Spinal and head injuries occur less frequently. Identifying factors associated with injuries is important for their prevention. They can be classified as non-modifiable, potentially modifiable,and modifiable. By addressing the latter two groups of factors, we can contribute to reducing the incidence of injuries. The main intrinsic factors linked to injury onset include age, a rapid growth period, previous injuries, joint laxity and instability, limb asymmetry, abnormal muscle stiffness, stress, fear,and lack of focus, while the main extrinsic factors are early specialization, training volume and duration. Most injuries occur during artistic gymnastics routines, especially during the floor exercise. Although more injuries happen during training sessions, the injury rate is higher during competitions. Furthermore, a higher number of injuries is associated with less experienced coaches and inadequate equipment.Preventive measures for gymnastics injuries revolve around training equipment,and healthcare modifications. Optimal landing technique, balanced workload, and comprehensive rehabilitation are crucial, alongside addressing mental and emotional strain.

Resumen
To investigate the generalization of correct parkour skill trials from physical education to parkour recess in elementary school as a function of skill level. Seven 2nd grade classes with 147 children (55 girls) received a 10-lesson sport education parkour season. During the season, children could voluntarily participate in five parkour recess sessions during lunch recess. Children’s voluntary participation in parkour recess was recorded and all skill trials in physical education and parkour recess were collected. There was no difference on voluntary participation in parkour recess between higher- (78%) and lower-skilled (77%) children. Higher-skilled children had higher percentages of correct skill trials than lower-skilled children in physical education (48% vs. 40%, p = .001) and parkour recess (42% vs. 32% p = .002). Most children voluntarily participated in parkour recess regardless of skill level. Parkour recess offered the opportunity to practice the skills learned in physical education.

Resumen
This study investigates the effects of parkour activity (PA) on physical fitness and grit for youth soccer athletes. True experimental research with a random control trial design for 12 weeks was adopted in this study. There were 78 male youth soccer athletes involved in the experimental (PA, n = 39) and control group (CG, n = 39) groups. The PA intervention program was carried out three times a week for 12 weeks. Pre-post-intervention tests were carried out to assess physical fitness and grit. The results of repeated measures ANOVA showed that there were significant effects of time, group, and time*group interaction on physical fitness (all, p <.05) and grit (all, p <.05). Meanwhile, Student's paired t-test results show that the PA group experienced significant differences scores between pre-and post-test in physical fitness (all, p <.05) and grit (all, p <.05), but in CG the differences were significant only occurred in sprint test 30m (p <.05), Illinois agility test (p <.05), hand grip test (p <.05) and there was no other difference, including grit (p >.05). In conclusion, we highlight that PA is the valid method to promote physical fitness and grit in youth soccer athletes.

Resumen
This case report describes a novel and unique combination of both electromagnetic and electrohydraulic focused extracorporeal shockwave therapy (ESWT) and extracorporeal magnetotransduction therapy (EMTT) for accelerated healing in a calcaneus epiphyseal fracture with delayed healing in an adolescent Parkour athlete. After a 2.5m jump, the 14-year-old experienced significant heel pain, however avoided telling his parents. After eight weeks, the initial imaging using ultra low dose weight-bearing cone beam CT (WBCT) revealed a calcaneus non-union situation adjacent to the open calcaneal physis. To improve and accelerate bony healing substantially, we chose to apply both combined focused electromagnetic (Storz Ultra, Storz Medical AG, Tägerwillen, CH) and focused electrohydraulic (MTS, Konstanz, Germany) ESWT in a fractioned fashion plus EMTT (Storz Magnetolith, Tägerwillen, CH) in five consecutive weekly sessions while allowing the patient to fully weight bear. The follow-up WBCT after six weeks revealed a near to total healing of the delayed union and being pain-free. Notably, combination therapy with focused ESWT and EMTT did not result in early closure of the calcaneal epiphysis. We conclude that combined focused electromagnetic and electrohydraulic ESWT and EMTT facilitate bony healing in adolescent calcaneal apophyseal fractures without any adverse effects on the open physis. Evidence level IV (case report).

Resumen
This study aimed to examine the effects of two different complex training protocols on physical performance in highly-trained youth basketball players. Fourteen adolescent players participated in twice-weekly sessions over eight weeks, following either the Drop Jump protocol (n = 7) or the Tic-tac protocol (n = 7), performing 1-3 sets of 8-9 exercises. Physical performance was assessed before and after the intervention using jumping tests (CMJ, squat, 10-5 hop jumps), change-of-direction speed (5-10-5), sprinting (0-20 meters), and muscular strength (isometric midthigh pull) tests. The intraclass correlation coefficient of within subjects measures was 0.95. Results showed no significant fixed effects for group or time on performance variables (p > 0.05), with greater variance attributed to measurements rather than group differences. The interindividual response to training was highly variable, contingent on the performance outcome. These findings suggest that the parkour-based Tic-tac protocol can be included in strength and conditioning programs for youth basketball players to enhance sport-specific actions. However, to improve physical performance in young team-sport athletes, it is crucial to address the individual needs of each athlete. This includes acknowledging the highly individualised responses to training stimuli.

Resumen
The purpose of this study was to assess the immediate effect of video feedback on the regulation and control of the standing back tuck somersault in the absence of vision. Two groups of male parkour athletes performed the standing back tuck somersault under both open and closed eyes conditions. The first group received video feedback, while the second group received verbal feedback. Concurrent analysis, including kinetic data from a force plate (Kistler Quattro-Jump) and kinematic data in two-dimensional by Kinovea freeware, was employed for motion and technical performance analysis. The results indicate that the loss of vision during the standing back tuck somersault affected only the take-off and ungrouping angle, as well as the vertical velocity and displacement. These effects were consistent regardless of the type of feedback provided (i.e., video feedback or verbal feedback). Furthermore, a significant Vision x Feedback interaction was observed at the level of technical performance. This suggests that the use of video feedback enabled the parkour athletes to maintain a high level of technical performance both with and without vision (i.e., 13.56 vs. 13.00 points, respectively, p> .05 and d= 2.233). However, the verbal feedback group technical performance declined significantly under the novision condition compared with the vision condition (13.14 vs. 10.25 points, respectively, with and without vision, p< .001 and d= 2.382). We concluded that when the movement is proprioceptively controlled (i.e., without vision), the video feedback enables the athletes to globally assess the technical deficiencies arising from the lack of vision and to correct them. These findings are discussed based on parkour athletes' ability to evaluate the kinematic parameters of the movement.

Resumen
The aim of this cross-sectional study was to compare acceleration outputs of the parkour-style “tic tac” action with those of the drop jump and the lay-up shot in youth basketball players. A total of 25 participants (17 boys, 13.80 ± 1.30 years of age; and eight girls, 15.00 ± 0.80 years of age) completed three trials of each action while wearing a single inertial motion capture unit with a sampling frequency of 200 Hz, positioned at the lumbar spine. All data were captured in a single session, using the same test order for all participants. Maximum resultant acceleration was calculated from the raw data for each action. Using sex and maturation status as covariates, data were analyzed using a Bayesian one-way repeated-measures analysis of covariance. Results revealed the jump + sex model to be the best fitting (BF10 = 9.22 × 105). Post hoc comparisons revealed that the tic tac produced greater maximal acceleration than the drop jump and the lay-up. These findings provide a biomechanical basis for the potential use of the parkour tic tac as an activity that could be used within the athletic development of youth basketball players.

Resumen
In this work, we present a system that detects Freezing of Gait Detection (FOG) that uses of a single wearable inertial sensor to automatically evaluate a Parkinson’s patient’s gait instability and detect FOG in real-time. A wearable vibrator is our cueing system which is triggered by the FOG detection whenever a FOG episode takes place. The vibration impulses help the patient to prevent FOG by switching to voluntarily movement execution. Sensor data were collected from nine patients with Parkinson’s disease performing Unified Parkinson’s Disease Rating Scale (UPDRS) test under the supervision of a clinical expert. Along with data recording, a video was taken from patient’s parkour. The data were labeled through the recorded video of the patient’s tests and FOG and non-FOG data were assigned. A machine learning model using a deep Long-Short-Term-Memory (LSTM) employ the accelerometer data from the sensor and the inference leads to a FOG or non-FOG classification. The FOG detection model is pruned, quantized and used for real-time inference on Google Coral board worn on the patient’ body. The model deployed on a Google coral board sends a trigger to the cuing device right after the FOG detection and the patient get alert for the happening FOG. The individualized model for one-second windows applied in this work performed an average of 91.5% of sensitivity and 86.5% specificity for models running on PC and 91.7% of sensitivity and 86.7% of specificity for the models tested on Google coral with the latency of 50 millisecond on real-time testing.
