Geriatric medicine and Olympic elite sports-parallels and philosophies.

The 30th Olympiad took place in July 2024. At first glance, sports science and training of elite athletes may appear to be of little relevance to geriatric medicine. However, there are important parallels between the practice of geriatric medicine and elite sports and lessons that we can learn from our sports science colleagues. Elite athletes and older people are operating at the margins of physiological capacity. Both benefit from tailored, scientifically informed training programmes delivered and monitored by a multidisciplinary team. There are parallels between the comprehensive geriatric assessment and the philosophy of marginal gains pioneered by British Cycling. Insights into the biology of skeletal muscle function are beginning to translate into the development of clinical interventions and substances that offer an unfair advantage in sport by improving muscle strength and physical performance may be of therapeutic benefit in sarcopenia. The 2024 Olympics provide an opportunity for us to learn lessons for excellence in our research and provide an opportunity to promote exercise across the life course-important for healthy ageing.

Risk Factors for Suicide Among Professional Athletes.

BACKGROUND: Suicide is a major public health concern that affects all demographics. Risk factors for suicide in professional athletes are poorly understood compared with the general population. The goal of this study was (1) to explore the current literature on risk factors for suicide in the population of professional athletes and (2) to formulate a proposed suicide risk identification tool as the first step in the production of a validated screening method specific to this population. METHODS: A comprehensive literature search for relevant publications was carried out through 7 databases. RESULTS: There is some evidence to suggest that retirement, anabolic androgenic steroid use, sexual abuse victimization, health problems, financial issues, relationship issues, having immigrant parents, having a financially disadvantaged childhood, using self-blame or behavioral disengagement as a coping strategy, changes in appetite or weight, sleep problems, reduced competitiveness, and thinking about a career after retirement are potential risk factors for suicide in this population. There is limited evidence to suggest that having a career in elite or professional sports, participation in contact sports, and participating in specific sports that are not associated with a higher suspected prevalence of performance-enhancing drug use are potential risk factors. CONCLUSIONS: This study identified potential risk factors for suicide among elite and professional athletes. These findings were used to help formulate a proposed suicide risk identification tool. Future research is recommended to explore and clarify specific risk factors for suicide in this population and to test the validity of the proposed tool.

Clinical and Imaging Outcomes Over 12 Weeks in Elite Athletes With Early-Stage Tendinopathy.

Knowledge of how to treat chronic tendinopathy has advanced in recent years, but the treatment of early tendinopathy is not well understood. The main purpose of this prospective observational study was to investigate if changes occur in clinical and imaging outcomes over 12 weeks in elite athletes with recent debut of tendinopathy. Sixty-five elite adult athletes (24 ± 5 years) with early Achilles or patellar tendinopathy (symptoms < 3 months) were examined at baseline and after 12 weeks. Patients were divided into groups based on the duration of symptoms at the time of inclusion: (T1): 0-1 month, (T2): 1-2 months, or (T3): 2-3 months. Pain-guided activity modification was the only intervention. We assessed the following clinical outcomes: Questionnaires (Victorian Institute of Sports Assessment (VISA)) and pain scores (0-10 numeric rating scale, NRS), structural outcomes from ultrasonography: Thickness, echogenicity, and Doppler flow, and from magnetic resonance imaging: Cross-sectional area (CSA), thickness and length. Tendinopathic Achilles and patellar tendons displayed no significant differences on imaging tendon structural outcomes between T1 (n = 19), T2 (n = 23), and T3 (n = 20) at baseline or after 12 weeks, with one exception: Patellar tendons in T1 were thicker than T2 and T3 at baseline. Although athletes improved clinically on VISA and most NRS scores after 12 weeks, affected tendons with greater thickness, CSA and Doppler flow than contralateral tendons at baseline remained unchanged after 12 weeks. In conclusion, these data suggest that early tendinopathy in elite athletes can improve clinically after 12 weeks while morphology remains unchanged.

Combined proteomics and metabolomics analysis reveal the effect of a training course on the immune function of Chinese elite short-track speed skaters.

INTRODUCTION: The aim of this study was to combine proteomics and metabolomics to evaluate the immune system of short-track speed skaters (STSS) before and after a training course. Our research focused on changes in urinary proteins and metabolites that have the potential to serve as indicators for training load. METHODS: Urine samples were collected from 21 elite STSS (13 male and 8 female) of the China National Team before and immediately after one training course. First-beat sports sensor was used to monitor the training load. Proteomic detection was performed using a Thermo UltiMate 3000 ultra high performence chromatography nano liquid chromatograph and an Orbitrap Exploris 480 mass spectrometer. MSstats (R package) was used for the statistical evaluation of significant differences in proteins from the samples. Two filtration criteria (fold change [FC] > 2 and p < 0.05) were used to identify the differential expressed proteins. The Kyoto Encyclopedia of Genes and Genomes enrichment analysis for differential proteins was performed to identify the pathways involved. Nontargeted metabolomic detection was performed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS_) with an ACQUITY 2D UPLC plus Q Exactive (QE) hybrid Quadrupole-Orbitrap mass spectrometer. Differential metabolites were identified using non-parametric statistical methods (Wilcox's rank test). Two filtration criteria (FC > 1.2 and p < 0.05) were used to identify differential metabolites. Combined analysis of proteomic and metabolomics were performed on the "Wu Kong" platform. Correlation analysis was performed using Spearman's rank correlation coefficient. RESULTS: (1) The most upregulated proteins were immune-related proteins, including complement proteins (C9, C4-B, and C9) and immunoglobulins (IgA, IgM, and IgG). The most downregulated proteins were osteopontin (OPN) and CD44 in urine. The correlation analysis showed that the content of OPN and CD44 (the receptor for OPN) in urine were significantly negatively correlated with the upregulated immune-related proteins. The content of OPN and CD44 is sex-dependent and negatively correlated with the training load. (2) The most upregulated metabolites included lactate, cortisol, inosine, glutamine, argininosuccinate (the precursor for arginine synthesis), 3-methyl-2-oxobutyrate (the catabolite of valine), 3-methyl-2-oxovalerate (the catabolite of isoleucine), and 4-methyl-2-oxopentanoate (the catabolite of leucine), which is sex-dependent and negatively correlated with OPN and CD44. (3) The joint analysis revealed five main related pathways, including the immune and innate immune systems. The enriched immune-related proteins included complements, immunoglobulins, and protein catabolism-related proteins. The enriched immune-related metabolites included cAMP, N-acetylgalactosamine, and glutamate. (4) There is a significant negative correlation between the content of OPN and CD44 in urine and the training load. CONCLUSION: One training course can lead to the activation of the immune system and a sex-dependent decrease in the content of OPN and CD44. Training load has a significant and negative correlation with the content of OPN and CD44, suggesting that OPN and CD44 could be potential indicators for training load.

Sticking the landing: A comparison of shod vs barefoot landing kinetics and foot muscle characteristics in gymnasts, cheerleaders, and non-athletes.

OBJECTIVES: The ability to control landings and stabilize quickly is essential in sports like gymnastics and cheerleading, where landing quality impacts scores. The similarities and contrasts between these sports, where one trains primarily barefoot and the other shod, may increase understanding of the kinetic role of the foot during landings. DESIGN: Sixteen gymnasts (GYM), sixteen cheerleaders (CHR), and sixteen non-athletes (NAT) performed single-foot shod and barefoot drop landings onto a force plate. METHOD: Foot muscle strength was assessed using a custom test and ultrasound imaging was used to measure six foot muscles. Group differences in muscle sizes and strength measurements were compared using one-way ANOVAs (α = 0.05). Landing mechanics metrics were evaluated using 3 x 2 between-within ANOVAs (α = 0.05). Pairwise comparisons were made using Tukey post-hoc tests. RESULTS: Barefoot landings resulted in greater peak vertical ground reaction force (pVGRF) and lower time to pVGRF (TTpVGRF). Significant group main effect differences were found between GYM and NAT for all kinetic measures (GYM: shorter time to stability (TTS) and TTpVGRF, and greater pVGRF), while no significant differences in landing kinetics were found between CHR and either GYM or NAT. No interactions were found between group and condition. GYM and CHR had significantly greater summed foot muscle size than NAT, however, only CHR displayed significantly greater toe flexion force than NAT. CONCLUSIONS: Our data suggests that while wearing shoes does not affect groups differently, footwear reduces initial peak VGRFs but does not influence later stabilization times.

Improvements in executive functions by domain-specific cognitive training in youth elite soccer players.

This study examined the impact of sport-specific cognitive training (CT) on executive functions (EFs) in youth soccer players. Thirty-one athletes (13-15 years) participated, 13 in the intervention group (IG) and 18 in the control group (CG). The IG underwent an 8-week soccer-focused CT program, while the CG maintained regular training. The assessments included working memory, inhibition, and cognitive flexibility tasks. The results revealed no significant improvements in EFs in the IG compared to those in the CG. Both groups showed enhanced cognitive flexibility, possibly due to general cognitive development or learning effects. The study suggested that an 8-week sport-specific CT may not enhance EFs in young soccer players, potentially due to a ceiling effect in highly skilled athletes. These findings should be considered when designing cognitive training programs for athletes, and future research could explore the optimal duration of such programs.

Impact of mindfulness on football coaches: A mixed design.

Mindfulness is an increasingly popular practice among elite athletes to improve performance and well-being, but its application for coaches is still very limited. Therefore, a new program (M×E; Mindfulness para Entrenadores) was designed and implemented online for 6 weeks for coaches, support staff, and technical directors. Participants were 58 (57 men), aged between 23 and 58 (M = 31.8). The between-subject analysis (RM ANOVA 2×2) included experimental (n = 26) and wait-list control group (n = 21). A total of 29 completed the within-subject analysis (RM ANOVA) completing follow-up measurements until six months. The analysis was complemented with 21 individual semi-structured interviews. The experimental group showed significant improvements in mindfulness trait (p < .001), interpersonal mindfulness (p = .010), and a significant improvement in emotional regulation (p = .010) in comparison to the wait-list control group. The experimental group's positive trend in all variables' levels was maintained until six months after the program. The qualitative analysis showed a positive impact on professional, personal, and social areas with improvements related to performance and well-being. Several participants considered the program as "fundamental" for their professional role. This study provides information on best practices in implementing mindfulness-based programs, highlighting their practical orientation, the training plan, and the safe space. These results offer initial validation of the potential of the M×E and invite sports organizations to incorporate mindfulness-based programs specially designed for coaches, support staff and technical directors.

A systematic review and network meta-analysis on the effectiveness of exercise-based interventions for reducing the injury incidence in youth team-sport players. Part 1: an analysis by classical training components.

OBJECTIVES: The primary purposes were (a) to estimate the pooled effects of injury prevention programs (IPPs) on reducing overall and some specific body regions (lower extremity, thigh, knee, and ankle) injury incidence rates (IIRs) and (b) to compare the effects of single- and multi-component IPPs on mitigating injury risk in youth team sport athletes. A secondary objective was to explore the individual effects of different components on these IIRs. MATERIALS AND METHODS: Searches were performed up to 15 January 2024 in PubMed, Web of Science, SPORTDiscus, and Cochrane Library. Eligible criteria were: exercise-based interventions evaluated against a control group, overall IIRs were reported, and youth (≤19 years old) team sport players. Two reviewers extracted data and assessed trial quality using the Consolidated Standards of Reporting Trials (CONSORT) statement, the Physiotherapy Evidence Database Scale (PEDro), and a risk of bias tool (Cochrane Back and Neck Group). Pooled effects were calculated by Frequentist random effects pairwise and network meta-analyses. RESULTS: Twenty-one studies were included. IPPs reduced overall, lower extremities, thigh, knee, and ankle IIRs by an average of approximately 35%. Most of the IPPs demonstrated statistically significant risk mitigation effects for overall and lower extremity injuries compared to control group. Interventions comprised exclusively of strength ([IRR = 0.3 [95%CI = 0.10-0.93]) and flexibility (IRR = 0.49 [95%CI = 0.36-0.68]), as well as those including stability exercises, were the most effective measures for reducing injuries in youth team sports. CONCLUSIONS: The implementation of current IPPs in training sessions for several weeks has shown to be an effective strategy for reducing the risk of injury in youth team sport athletes by one-third. Indirect evidence suggests that strength, flexibility, and stability might be exercise components with the highest risk mitigation effects; however, more research is crucial to confirm our estimates with direct evidence.

Injury prevention programs could reduce around one-third the incidence of injuries occurring in youth team sport athletes.Strength, flexibility, and stability seem to be key exercise-based components to be included in any training program aimed at minimizing the risk of injury in youth.Further research comparing head-to-head injury prevention programs in youth athletes is needed to make more founded conclusions on their true risk mitigation effects.

Implication of microRNAs as messengers of exercise adaptation in junior female triathlonists.

While expression profile of muscle-specific miRNAs following endurance training is well-characterized, information about exercise-induced changes of metabolism-regulating miRNAs is limited, especially in female and junior athletes. Major aim of this study was to examine a set of miRNAs related to mitochondrial function and metabolism in highly professional junior female athletes. The Hungarian National Junior Triathlon Team (n = 4), completed standardized running and cycling sessions. Expression levels of miR-133a, miR-210, miR-494 and miR-127-3p were determined by RT-qPCR in whole blood and serum samples, withdrawn directly before, and after the exercise, and 24 and 48 h later. The expression of miR-494, miR-127-3p and miR-210 showed strong correlation with each other. In serum, nearly significant increment of miR-127-3p levels was detected, that may be a novel biomarker of exercise adaptation. Its expression was significantly higher than that of miR-210. In whole blood, significantly higher miR-210 than miR-494 and miR-127-3p levels were observed. MiRNA expression profile of the youngest athlete was markedly different compared to others. Our results suggest that miRNAs related to mitochondrial function and metabolism are involved in exercise adaptation. The present study may facilitate further research with larger potential participant pools, contributing to improved prevention and treatment of chronic diseases of civilization.

Effects of resisted sprint training with ball on speed and agility performance in U-19 elite soccer players.

The purpose of this study was to analyze the effects on speed and agility of including ball driving during resisted sprint training in relation to regular soccer training. Thirty male soccer players (age: 18.10 ± 0.66 years; height: 179 ± 0.06 cm; body mass: 76.22 ± 4.76 kg; systematic practice: 8.6 ± 1.73 years) participated in the study and were randomly assigned to an experimental group (EG; n = 18) or a control group (CG; n = 12). The research was conducted during a training camp. The intervention period lasted 6 weeks and during that period all players performed their usual soccer training. However, the EG performed two weekly sessions of a supplementary training of resisted sprints with a ball. Within-group analysis showed significant improvements in 5-m (p = 0.005) and 10-m (p = 0.016) sprint performance; and New multi-change of direction agility test (NMAT; p = 0.002), Illinois (IAT; p = 0.002), T-test (p = 0.003), Arrowhead COD (Arrowhead-R, p = < 0.001; Arrowhead-L, p = < 0.001) test and Zigzag agility test (Zigzag-B; p = 0.006) from pretest to posttest in EG. However, the CG didn't show any significant improvements. Between-groups analysis revealed differences in favor of the EG in Zigzag-B, IAT, Arrowhead-R, Arrowhead-L and NMAT. This study's results support the efficacy of a short-term training program that includes resisted sprints exercises to improve the performance of soccer players.

Eating disorders among physically disabled national athletes in Malaysia.

INTRODUCTION: Eating disorders are becoming a cause of concern amongst athletes in recent times. The objective of this study was to determine the prevalence of eating disorders amongst physically disabled athletes in Malaysia. Athletes were sampled and screened for eating disorders utilising the Eating Disorder Examination-Questionnaire 6.0 (EDE-Q-for females) and the Eating Disorder Assessment in Males (EDAM-for males). MATERIALS AND METHODS: Athletes were approached individually, and they responded via an online questionnaire. A total of 271 athletes responded (sample needed 269) from the total of 700 athletes (38.7%). RESULTS: From the total, 14.4% (n = 39, 95% CI = 10.56-19.28) of the athletes had eating disorders (14.4% of the male athletes and 14.5% of female athletes). The final model of a binary logistic regression was conducted and found that the higher the body weight (AOR: 1.02, 95% CI: 1.00-1.04, p = 0.03), the higher the income (AOR: 0.992, 95% CI: 0.990- 0.994, p = 0.02), the more athlete suffered from coaches intimidating behaviours(AOR: 1.17, 95% CI: 1.03-1.33, p = 0.02), a perception of having stress (AOR: 7.61, 95% CI: 1.69-34.39, p = 0.01) and having stress (AOR: 3.70, 95% CI: 1.02-9.68, p = 0.04) were common factors seen in athletes with eating disorders. CONCLUSION: About two in every 10 disabled athletes suffered from eating disorders.

Sport mental health continuum in young Brazilian athletes: adaptation and psychometric properties.

Instruments used to assess the mental well-being of young athletes in Brazil are scarce. Therefore, the present study aimed to translate, cross-culturally adapt for young athletes, and gather evidence of validity for the Sport Mental Health-Short Form (S-MHC) for use in Brazilian Portuguese. The research was conducted in five stages: translation, synthesis, back-translation, expert review, and validation of the psychometric properties. For validation, 246 young athletes of both genders (88 females, 35.8%), aged between 12 and 18 years (14.5 ± 1.9 years), were recruited. Psychometric methods were employed to confirm and validate the translated and adapted versions of the S-MHC for young athletes, including internal consistency using Cronbach's alpha and McDonald's omega, composite reliability, Item Characteristic Curve (ICC) using Item Response Theory (IRT), and Confirmatory Factor Analysis (CFA). Two structures were tested, with Model 1 loading the 14 items of the translated version of the S-MHC into a single latent factor and Model 2 loading the items into three factors related to emotional, social, and psychological sport well-being. Both models showed good validity, consistency, and reliability measures and can be used to investigate the sport well-being of young athletes. It was concluded that the translated version of the S-MHC in Brazilian Portuguese can be used to assess the sport well-being of young athletes in Brazil. Model 2 structure is recommended to observe the different nuances of emotional, social, and psychological well-being.

The effect of post-activation enhancement on the performance of Chinese national skeleton athletes in the "ice push sled"-a first cross-sectional study.

Objective: To investigate the impact of post-activation potentiation (PAP) induced by resisted sled sprint at different loads on the subsequent 30 m ice push sled performance of Chinese skeleton athletes, and to identify the resisted sled sprint load that most effectively enhances PAP for Chinese skeleton athletes. Methods: Seven elite athletes from the Chinese skeleton team participated in four tests with more than 48 h intervals. During the tests, on the first test, athletes completed a 40 min standard warm-up, rested for 6 min, and then performed a 30 m test. On the second, third, and fourth test, athletes completed the standard warm-up, then performed 20 m sprints with resisted sled (RS) at 75%, 50%, and 25% of body mass (BM), respectively, rested for 6 min, and then performed the 30 m test. Results: No significant differences were found in morning pulse, blood urea, and creatine kinase levels among four tests. The percentage of maximum heart rate (%HRmax) within different intensity ranges showed no significant differences among four tests. However, significant differences were observed in ice push sled performance among four tests (No BMRS: 5.08 ± 0.27; 25% BMRS: 5.05 ± 0.29; 50% BMRS: 5.02 ± 0.27; 75% BMRS: 5.04 ± 0.28). Post hoc analyses revealed that the 50% BMRS test had faster speed compared to the no resistance (p < 0.05), the 25% BMRS (p < 0.05), and the 75% BMRS (p < 0.05) tests. Additionally, the 75% BMRS test had faster speed than the no resistance test (p < 0.05). Conclusion: A 20 m sprint with 50% BMRS effectively enhances the PAP effect in skeleton athletes, improving their ice push sled performance. Coaches can incorporate this resisted sled sprint in athletes' training routines for performance enhancement in both daily training and pre-competition preparations.

Locked Posterior Shoulder Dislocation with Accompanying Fracture: A Debilitating Rare Injury for Athletes?

Shoulder dislocation is undoubtedly one of the most common injuries in traumatology. Posterior dislocation of the shoulder is regarded as comparatively rare compared to anterior dislocation, whilst it is strikingly extraordinary for this type of injury to be accompanied by a concomitant fracture. Accurate diagnosis and appropriate treatment can be considerably demanding, while being vitally important in this exceedingly rare condition. These injuries are broadly considered to be under-reported in the existing literature, especially among high-demand athletes. We present a rare case of a high-demand athlete sustaining a traumatic locked posterior shoulder dislocation with an accompanying fracture treated in our Institution. A detailed clinical examination and plain radiography revealed the peculiar condition, and a CT scan was subsequently performed for more thorough evaluation of the injury. The patient underwent surgery on the day following admission for repair of the extensive shoulder damage, and a deltopectoral approach was utilized. Reduction of the metaphyseal fracture and the dislocation was accomplished with gentle manipulations, and stabilization was obtained with an anatomic plate. A modified McLaughlin procedure was carried out to address the reverse Hill-Sachs lesion. The postoperative period was uneventful, followed by a painstaking physical rehabilitation program, and the patient returned successfully to his sporting activities 6 months postoperatively. By presenting this thought-provoking case, we stress the challenging nature of these immensely infrequent injuries while also highlighting the requirement for more sensitive factor-specific studies regarding their optimal treatment.

Recalibrated FRIEND equation for peak oxygen pulse is accurate in endurance athletes: the NOODLE study.

Peak oxygen pulse (O2Ppeak) is an important index of cardiorespiratory fitness (CRF). The FRIEND database is a global source of reference values for CRF. However, no reference equation is tailored for endurance athletes (EA) to predict O2Ppeak. Here, we adjusted the well-established FRIEND equation for O2Ppeak to the characteristics of the EA population. 32 (34.0%) female EA and 62 (66.0%) male well-trained EA underwent maximal cardiopulmonary exercise test on a treadmill. V̇O2max was 4.5 ± 0.5 L min-1 in males and 3.1 ± 0.4 L min-1 in females. O2Ppeak was 23.6 ± 2.8 mL beat-1 and 16.4 ± 2.0 mL beat-1 for males and females, respectively. Firstly, we externally validated the original FRIEND equation. Secondly, using multiple linear regression, we adjusted the FRIEND equation for O2Ppeak to the population of EA. The original FRIEND equation underestimated O2Ppeak for 2.9 ± 2.9 mL beat-1 (P < .001) in males and 2.2 ± 2.1 mL beat-1 (P < .001) in females. The updated equation was 1.36 + 1.07 (23.2 · 0.09 · age - 6.6 [if female]). The new equation explained 62% of the variance and significantly predicted O2Ppeak (R2 = 0.62, ß = 0.78, P < .001). The error of the EA-adjusted model was 0.1 ± 2.9 mL beat-1 (P = .82) and 0.2 ± 2.1 mL beat-1 (P = .65) for males and females respectively. Recalibration of the original FRIEND equation significantly enhances its accuracy among EA. The error of the EA-adjusted model was negligible. A new recalibrated equation should be used to predict O2Ppeak in the population of EA.

The impact of fatigue on dynamic balance in coopers athletes with chronic ankle instability.

Athletes who have successfully regained high sports performance despite prior inversion injuries, and who do not have persistent symptoms, are referred to as "copers" in the literature. The aim of the study was to assess dynamic stability under fatigue in patients with chronic ankle instability in comparison to healthy controls. We conducted a case - controlled study on a group of 60 young, physically active individuals aged 29.8 ± 4.6. They were divided into 3 groups: I - unilateral ankle instability n = 14, II - bilateral ankle instability n = 15, III - no ankle instability, n = 31. All participants filled out questionnaires on the health, the FADI and FADI-S. The study protocol consisted of a dynamic stability measurements by Biodex Balance System, followed by a fatigue test, followed by the series of the same measurements. General stability index value before and value after fatigue test did not differ significantly. The differences between groups in measurements taken before fatigue test (F (2.49) = 1.59; p = 0.214; ηp2 = 0.06) and after fatigue test also proved insignificant (F (2.49) = 1.28; p = 0.286; ηp2 = 0.05). The incidence of structural ankle instability did not affect functional stability. "Copers" had efficient neural-muscular control in dynamic stabilography tests.

Sex difference in IRONMAN age group triathletes.

BACKGROUND: The sex difference in athletic performance has been thoroughly investigated in single sport disciplines such as swimming, cycling, and running. In contrast, only small samples of long-distance triathlons, such as the IRONMAN® triathlon, have been investigated so far. AIM: The aim of the study was to examine potential sex differences in the three split disciplines by age groups in 5-year intervals in a very large data set of IRONMAN® age group triathletes. METHODS: Data from 687,696 (553,608 men and 134,088 women) IRONMAN® age group triathletes (in 5-year intervals from 18-24 to 75+ years) finishing successfully between 2002 and 2022 an official IRONMAN® race worldwide were analyzed. The differences in performance between women and men were determined for each split discipline and for the overall race distance. RESULTS: Most finishers were in the age group 40-44 years. The fastest women were in the age group 25-29 years, and the fastest men were in the age group 30-34 years. For all split disciplines and overall race time, men were always faster than women in all groups. The performance difference between the sexes was more pronounced in cycling compared to swimming and running. From the age group 35-39 years until 60-64 years, the sex differences were nearly identical in swimming and running. For both women and men, the smallest sex difference was least significant in age group 18-24 years for all split disciplines and increased in a U-shaped manner until age group 70-74 years. For age groups 75 years and older, the sex difference decreased in swimming and cycling but increased in running. Considering the different characteristics of the race courses, the smallest performance gaps between men and women were found in river swimming, flat surface cycling and rolling running courses. CONCLUSIONS: The sex difference in the IRONMAN® triathlon was least significant in age group 18-24 years for all split disciplines and increased in a U-shaped manner until age group 70-74 years. For 75 years and older, the sex difference decreased in swimming and cycling but increased in running.

Psychological traits of extreme sport participants: a scoping review.

BACKGROUND: Extreme sports have increased in popularity, particularly over the past two decades. Theories explaining participation in extreme sports tend to focus on risk. Consequently, extreme sports participants are often characterized by an accentuated desire for risk and abnormal personal traits, but the positive aspects of extreme sports are often neglected in the literature. This scoping review summarizes extreme sport motives, emotions and personal characteristics. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) Checklist, three databases were searched (PubMed, Web of Science, Scopus, SportDiscus and, PsycInfo) on 20th April 2023. Studies were included if they were originally articles written in English and examined psychology traits in extreme sport participants. RESULTS: In total, 39 manuscripts met the inclusion criteria and were analyzed in the present review. There is no unique profile for individuals involved in extreme sports. Risk and fear are considered natural characteristic of participation, and many positive aspects are associated with involvement in extreme sports (e.g., organization, planning, confidence). The quality of experience is often reported to justify extreme sport participation. CONCLUSION: Changes in emotions and motives characterized the reversal theory, which in combination with the flow approach, could explain the participation in extreme activities. A dynamic ecological approach considering the interaction between individuals and the environment should be adopted to understand individual motives, behaviour and emotions.

Very high-speed running (VHSR) profile in elite female football: An update.

The aim of the present study it's a providing an update of the profile of very high-speed running (VHSR) of professional female football players. In this study 23 official matches of the Spanish First Division of Women´s Football were analysed. A total of 15 players participated, who were classified according to their location on the matches played: central-corridor (CCP, n = 7), and lateral-corridor (LCP, n = 8). The variables recorded were: 1) Very High-Speed Running (VHSR), considering the accumulated distance, duration, and frequency, and the individual characteristics of the efforts (distance and duration); 2) Recovery between efforts (VHSRe) and; 3) VMAX. The results show that LCP described higher values in accumulative VHSR and VHSR by distance bands, with greater distances, durations and VMAX of VHSRe, with less recovery between efforts. There seems to be an evolutionary trend in the distribution of the efforts, with a higher % of efforts in the 10-20 m band. The results provide useful information that coaching staff of professional women's football teams could use to design specific very high-speed running training to optimize performance in competition.
