ABSTRACT
CONTEXT AND OBJECTIVES: Respiratory muscle training (RMT) is considered an effective tool to improve cardiorespiratory limitations in athletes. The goals of this systematic review were to explore the role of RMT and its implementation within sport rehabilitation programs in para-athletes. EVIDENCE ACQUISITION: Several databases were searched until January 2024. Eligible studies were independently reviewed by 2 reviewers. Quality assessment was made using the PEDro scale and version 2 of the Cochrane Risk-of-Bias Tool for Randomized Trials. Eight studies (a total of 108 participants) were selected for the analysis. EVIDENCE SYNTHESIS: Five studies preferred using resistive loading, while 2 studies used normocapnic hyperpnea, and 1 study used threshold inspiratory muscle training. Respiratory functions (respiratory muscle strength and endurance, spirometry measures) and exercise performance were assessed as the main outcomes. Significant increases in respiratory muscle strength were reported in 5 studies. Two studies observed improvement in respiratory muscle endurance and 3 studies reported increased exercise capacity. CONCLUSIONS: This review suggests that although RMT can enhance respiratory muscle strength and endurance, it should not be considered the primary method for boosting the exercise performance of para-athletes. Additional research is necessary to explore the impact of various RMT techniques on different outcomes from the perspective of sport rehabilitation in para-athletes.

OBJECTIVE: There is a lack of prospective data on mental health of elite Para athletes. The objective was to identify and follow elite Para athletes at risk of mental health problems. METHODS: In a 124-week prospective cohort study, mental health of German elite Para athletes was monitored using the Patient Health Questionnaire-4 (PHQ-4). In case of positive screening (PHQ-4≥5) over 2 weeks, a follow-up contact was conducted by a sports psychiatrist, who asked the athletes about their mental condition and sources for their mental distress and offered support. RESULTS: 7543 PHQ-4 scores were obtained from 122 Para athletes with a mean weekly response rate of 84%. The PHQ-4 screening was considered positive for symptoms of depression or anxiety with a prevalence of 6.7%, affecting 48.4% (n=59) of all participants at some point during the study period. In 76.6% (n=49) of all follow-up contacts, athletes (n=34) reported at least one mental health problem, most frequently mental distress (n=31), followed by symptoms of depression (n=19) including acute suicidality (n=1). The most common mental stressors cited were related to education and problems with the team, coaches or federation. At follow-up, almost two-thirds of the athletes were either already in professional psychiatric or psychological care (25%) or were recommended to seek such care (32.8%). CONCLUSION: Our screening and follow-up system revealed high rates of mental health problems in elite Para athletes. Programmes for early identification with mental health monitoring under the supervision of mental health professionals should be considered by sports federations for Para athletes.

BACKGROUND: In the contemporary era, there is a growing emphasis on understanding the self-realization of personality, encompassing individual-psychological traits, abilities, knowledge, skills, and motivation, extensively studied in psychology. Notably, limited attention has been given to exploring motivational determinants influencing athlete self-realization based on their professional qualifications. This gap is particularly pertinent in Kazakhstan, where significant efforts are directed towards athlete preparation. METHODS: Employing a systemic approach by Bagadirova and Kudinov, the study views athlete self-realization as a multi-level phenomenon with interconnected components. A total of 180 athletes participated, including 60 professionals (average age 23.9), 60 amateurs (average age 31.1), and 60 Paralympians (average age 24.4). The methodological toolkit comprises four diagnostic techniques: E.A. Kalinin's "Motives of Sports Activities" (MSA) questionnaire, S. Maddi's resilience test adapted by D.A. Leontiev and E.I. Rasskazova, and S.I. Kudinov's multidimensional questionnaire on self-realization. RESULTS: Significant differences in motivational determinants and self-realization attitudes emerge across athlete groups based on their sports qualifications. Noteworthy aspects include declining in motivation among professional athletes of masters of sports and masters of sports of international class, and rigidity in life resilience among Paralympic athletes. Overall, self-realization levels are not high, with extremely low levels of professional self-realization in all three athlete categories. CONCLUSIONS: The study's scientific novelty lies in systematically organizing knowledge on fundamental motivational determinants impacting athlete self-realization according to professional qualifications. This research addresses the acute shortage of psychological studies in sports psychology for Kazakhstan, which is still in its early stages. The findings underscore the need for targeted interventions by coaches and sports psychologists to enhance motivation levels, especially among elite athletes, and foster resilience, particularly in Paralympic athletes, ultimately advancing the field in the country.

The study aimed to assess loneliness experiences among athletes with disabilities (AWD) during the different phases of the pandemic and to understand its relationship with coping styles. Ninety-one AWD participated in a longitudinal study spanning 10 months, covering three time points: April (A), June (Time B), and November (Time C) 2021. The study used the Coping Inventory for Stressful Situations and the revised University of California Los Angeles Loneliness Scale-Revised (UCLA-R) to measure coping mechanisms and feelings of loneliness, respectively. Loneliness levels peaked during the most intense phase of the pandemic, showing significant differences between consecutive time points (χ2 = 20.29, p < 0.001, d = 0.24). The most robust regression models were built in Time B, using the "intimate contacts" dimension of loneliness as the dependent variable and "emotion-oriented coping", "avoidance-oriented coping", and "impairment" as independent variables, explaining 44% of the variance (p < 0.001). Loneliness among Paralympic athletes fluctuated during various phases of the pandemic. The findings highlight the significant influence of coping styles, particularly emotional styles which heightened perceived loneliness, and task-oriented styles which reduced it, on athletes' experiences of loneliness. These results underscore the need for longitudinal studies to delve deeper into the relationship between loneliness and mental health. Moreover, they stress the importance of developing tailored interventions that promote effective coping mechanisms in AWD during challenging times amid to COIVID-19.

OBJECTIVE: To describe the prevalence of urinary incontinence (UI) in para athletes in Brazil. METHODS: This is a cross-sectional study with Brazilian para athletes with physical impairments from all para sports. The data from 86 participants of both sexes (60 males and 26 females) were collected through an online survey that gathered sociodemographic data and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, from March to July 2023. RESULTS: The prevalence of UI was 45.3% (n=39), with the average impact on quality of life scored at 6.1±3.5 on a scale of 0-10. Most para athletes reported moderate (43.5%) or severe (38.4%) symptoms. The most common type was mixed UI (46.1%), with an average of 3±1.9 episodes of urinary loss per athlete in the last 4 weeks. Adjusted Poisson regression (controlling for sex, age and level of competition) revealed that para athletes with orthopaedic impairments had a 58% lower prevalence of UI (prevalence ratio=0.42; 95% CI 0.24, 0.83) compared with those with neurological impairments. Furthermore, ordinal regression indicated that para athletes with neurological impairments were 147% more likely to experience a progression from 'severe' to 'very severe' UI (OR=2.47; 95% CI 1.59, 3.93). CONCLUSIONS: UI is highly prevalent among para athletes, particularly those with neurological impairments, underscoring the need for specialised genitourinary healthcare and the need for further treatment and monitoring of the condition. There is a critical need to raise awareness among coaches, healthcare providers and the athletes themselves about UI and its impact to foster the comprehensive well-being of these athletes.

INTRODUCTION: Recently, European Society of Cardiology (ESC) validated a prediction model to estimate 10-year fatal and non-fatal cardiovascular disease risk (CVDR) in individuals (aged 40-60 years) without previous cardiovascular disease or diabetes (ESC-SCORE2) and to provide indications for treatment. At present, data describing the CVDR in Paralympic athletes (PAs) are scarce and inconsistent. Therefore, we sought to assess the prevalence of risk factors in PAs to estimate their CVDR through SCORE2. METHODS: We enrolled 99 PAs aged ≥ 40 y.o., who participated at 2012-2022 Paralympic Games, competing in 22 different sport disciplines classified according to sport type (power, skills, endurance and mixed) and disabilities: spinal cord injuries (SCI) and non-SCI. CVDR factors, anthropometric measurements and blood samples were collected. RESULTS: Among the 99 PAs (78% males, mean age 45.7 ± 4.7 y.o.), 52.5% had SCI; 54% were dyslipidemic and 23% were smokers. According to ESC-SCORE2, 29% had high and 1% very-high CVDR. Women (compared to men) and endurance (compared to other sport) exhibited better CV profile. SCI showed no differences when compared with non-SCI for CVDR, excepted for a lower HDL and lower exercise performance. None of the dyslipidemic athlete was on pharmacologically treatment, despite the altered lipid profile had already been detected at younger age. CONCLUSION: PAs are a selected population, presenting a high CV risk profile, with 30% showing either high or very-high CVDR according to ESC-SCORE2. Dyslipidemia was the most common risk factor, underestimated and undertreated, emphasizing the need for specific preventive strategies in this special setting of athletes.

BACKGROUND: Isthmic spondylolysis represents the most common cause of spinal pain in adolescent athletes. This article provides an overview of the classification, diagnosis, and treatment options for these conditions, including conservative and operative measures. It also provides a treatment pathway to how young athletes with spondylolysis should be treated. DIAGNOSTICS: Diagnostic imaging techniques are essential for an accurate diagnosis, with CT scans providing additional information for surgical planning. TREATMENT: Conservative treatment focuses on activity modification and physiotherapy, with a phased approach tailored to individual patient needs. Operative intervention may be considered if conservative measures fail, with minimally invasive techniques such as Buck's screw fixation showing promising results. The decision between conservative and operative management should consider factors of the patients' individual profile. In this paper, we present the first treatment algorithm for the treatment of isthmic spondylolysis. Long-term prognosis varies, with most athletes able to return to sport following treatment.

OBJECTIVE: This study aims to evaluate the effect of a performance-focused swimming programme on motor function in previously untrained adolescents with cerebral palsy and high support needs (CPHSN) and to determine whether the motor decline typical of adolescents with CPHSN occurred in these swimmers. METHODS: A Multiple-Baseline, Single-Case Experimental Design (MB-SCED) study comprising five phases and a 30-month follow-up was conducted. Participants were two males and one female, all aged 15 years, untrained and with CPHSN. The intervention was a 46-month swimming training programme, focused exclusively on improving performance. Outcomes were swim performance (velocity); training load (rating of perceived exertion min/week; swim distance/week) and Gross Motor Function Measure-66-Item Set (GMFM-66). MB-SCED data were analysed using interrupted time-series simulation analysis. Motor function over 46 months was modelled (generalised additive model) using GMFM-66 scores and compared with a model of predicted motor decline. RESULTS: Improvements in GMFM-66 scores in response to training were significant (p<0.001), and two periods of training withdrawal each resulted in significant motor decline (p≤0.001). Participant motor function remained above baseline levels for the study duration, and, importantly, participants did not experience the motor decline typical of other adolescents with CPHSN. Weekly training volumes were also commensurate with WHO recommended physical activity levels. CONCLUSIONS: Results suggest that adolescents with CPHSN who meet physical activity guidelines through participation in competitive swimming may prevent motor decline. However, this population is clinically complex, and in order to permit safe, effective participation in competitive sport, priority should be placed on the development of programmes delivered by skilled multiprofessional teams.

This study explored the classification experiences and views of Para Alpine skiers with visual impairment. Data from 11 interviews were analyzed using reflexive thematic analysis to generate three themes: Suitability-The skiers questioned the suitability of the visual measurements, testing environment, and the information they received regarding classification; Exclusivity-Skiers felt certain aspects of the system remain exclusive due to the restrictions of sport classes and lack of the athlete voice; and (Dis)trust-Skiers felt distrust in those implementing the system and in other athletes due to intentional misrepresentation. Speculation surrounding this resulted in the skiers' feeling doubt in their own classification. While there is not a "one size fits all" approach to classification, understanding skiers' experiences can be a vital first step and will help to guide future research into the evolution of this sport's classification.

OBJECTIVE: A periodic health evaluation (PHE) is a comprehensive and multidisciplinary investigation of athlete health widely used in elite sport, but its contents and benefits can be questioned. This study aimed to determine the prevalence of conditions identified by a PHE among Paralympic and Olympic athletes over four consecutive Games cycles from Rio de Janeiro 2016 to Beijing 2022 and to assess the benefits and potential pitfalls of a comprehensive PHE programme in detecting existing injuries, illnesses and other health issues. METHODS: We collected extensive health history and clinical examination data on elite athletes: medical history, ECG, blood pressure, blood samples, spirometry, musculoskeletal health, cognitive function, mental health and compliance with public health programmes. RESULTS: The final cohort included 87 Paralympic and 367 Olympic athletes, representing 565 PHE cycles. Musculoskeletal problems and unspecified pain, infections and allergies were the most frequent health issues. High blood pressure was the most prevalent cardiovascular finding, and vitamin D deficiency the most common laboratory abnormality. Most athletes complied with the public childhood vaccination programmes, but fewer with recommended cancer screening. Follow-up of health issues was variable. CONCLUSION: Our PHE programme identified musculoskeletal problems, infections, allergies, elevated blood pressure and vitamin D deficiency as common health conditions. Longitudinal follow-up of health conditions identified during screening and improved compliance with public health and cancer screening programmes is needed to determine the true benefits of athlete care prompted by the PHE.

OBJECTIVE: To investigate whether transcranial direct-current stimulation (tDCS) optimizes the performance of a wheelchair basketball player on precision tasks. METHODS: A right-handed wheelchair basketball player (1.5 points functional class) with myelomeningocele (low lumbar level) participated in this case study. The tDCS neuromodulation protocol was applied throughout 10 interventions of 20 minutes with a current intensity of 2 mA, simultaneously with sport-specific training, 3 times a week for 4 weeks. Anodic stimulation was performed on the right cerebellar hemisphere (CB2) and cathodic stimulation in the left dorsolateral prefrontal cortex. A control participant was submitted to a sham-tDCS stimulation protocol for the same period. Functional performance was assessed before the intervention and after the 5th and 10th interventions using "pass accuracy," "free-throw shooting," and "spot shot" tests. Outcome measures were compared using percentage differences between preintervention, intermediate intervention, and postintervention values. RESULTS: There was a gradual increase in the athlete's total and average scores in all tests performed, with an overall improvement of 78% between the baseline and final assessments, while the control participant had an overall improvement of 6.5%. CONCLUSION: The tDCS protocol was effective in improving performance in precision activities in a wheelchair basketball player.

Dyslipidemia is the most frequent cardiovascular (CV) risk factor in able-bodied athletes and is frequently undertreated, resulting in an underestimated risk of atherosclerosis-related diseases. Data on lipid profile in Paralympic athletes are lacking. Our study aimed to identify the prevalence of dyslipidemia and the influence of disability type and sporting discipline in Paralympic athletes. We evaluated 289 athletes who participated in the Paralympic Games from London 2012 to Beijing 2022. All athletes underwent clinical/physical evaluation, blood tests, and body composition analysis. They were divided into different groups based on sports disciplines and disability type (spinal cord injuries [SCIs] and non-SCIs [NSCIs]). Among the Paralympic athletes, 34.6% had a low-density lipoprotein (LDL) level ≥115 mg/100 ml. They were older (38.1 ± 9.2 vs 30.6 ± 9.6, p = 0.001) and had a higher CV risk. Athletes with SCI showed similar total cholesterol and triglycerides, higher LDL (110.9 ± 35.2 vs 102.7 ± 30.6 mg/100 ml, p = 0.03) and lower high-density lipoprotein (HDL) (53.6 ± 13.6 vs 60.5 ± 15.4 mg/100 ml, p = 0.001) than those with NSCI. Endurance athletes had lower LDL, the highest HDL, and the lowest triglycerides and LDL/HDL ratio compared with other sports disciplines. A mean follow-up of 61.5 ± 30.5 months was available in 47% athletes, and 72.7% of the athletes with dyslipidemia continued to present altered LDL values at follow-up. In conclusion, dyslipidemia is the most common CV risk factor in the Paralympics, affecting 35% of athletes, with only mild lipid changes over a medium-term time. The type of disability and sporting discipline has an impact on lipids, improving HDL and reducing LDL, with a better profile observed in NSCI and endurance athletes.

OBJECTIVES: To investigate if the sport concussion assessment tool version 5 (SCAT5) could be suitable for application to Para athletes with a visual impairment, a spinal cord injury, or a limb deficiency. METHODS: A 16-member expert panel performed a Delphi technique protocol. The first round encompassed an open-ended questionnaire, with round 2 onwards being composed of a series of closed-ended statements requiring each expert's opinion using a five-point Likert scale. A predetermined threshold of 66% was used to decide whether agreement had been reached by the panel. RESULTS: The Delphi study resulted in a four-round process. After round 1, 92 initial statements were constructed with 91 statements obtaining the targeted level of agreement by round 4. The expert panellist completion rate of the full four-round process was 94%. In the case of athletes with a suspected concussion with either limb deficiencies or spinal cord injuries, the panel agreed that a baseline assessment would be needed on record is ideal before a modified SCAT5 assessment. With respect to visual impairments, it was conceded that some tests were either difficult, infeasible or should be omitted entirely depending on the type of visual impairment. CONCLUSION: It is proposed that the SCAT5 could be conducted on athletes with limb deficiencies or spinal cord injuries with some minor modifications and by establishing a baseline assessment to form a comparison. However, it cannot be recommended for athletes with visual impairment in its current form. Further research is needed to determine how potential concussions could be more effectively evaluated in athletes with different impairments.

Improvements in race times for male and female Para canoe athletes across different sports classes have led to a reduction in relative differences between classes over time. However, there is a lack of research examining the comparative developmental trajectories between high-performance Paralympic (PCS) and Olympic (OCS) canoe sprint. In this study, we compared the developmental trajectories of 200-meter kayak performances among PCS and OCS athletes. In total, we analyzed 628 race results obtained from public online databases, for nine competitions between 2015 and 2023. Race times were reduced over the years except in specific sports classes (KL3-M, K1-M, and K1-F; KL: Kayak Level, M: male, F: female), with a poor positive correlation (r = 0.17 to 0.33) between time and the years. For the remaining sports classes, these correlations ranged from poor to fair (r = -0.58 to -0.13). OCS K1 athletes outperformed their Paralympic counterparts. Among Paralympic classes, KL1 had slower times than KL2 and KL3 (p ≤ .05), with KL2 times significantly lower than KL3 in the female category. OCS athletes exhibited less variability in race times compared to PCS athletes. In the male category, there were no significant differences in the coefficients of variation (CV) and amplitude of race times between sport classes, except for KL1-M, which had a larger CV than K1 (p ≤ .05). In the female category, the CV and amplitude of race times were significantly higher in KL1-F compared to KL3-F and K1-F. OCS times remained stable from 2015, with KL3-M following a similar trend. PCS displayed greater race time variability, particularly in higher impairment classes, notably KL1. This underscores the existence of distinct developmental stages within the canoe sprint modality, particularly emphasizing the early developmental phase of KL1. It also provides valuable insights for coaches and sports selection, especially concerning athletes with more severe impairments, including those in Rehabilitation Centers and during athlete recruitment.

World Athletics use maximum allowable standing height (MASH) equations for para-athletes with bilateral lower extremity amputations to estimate stature and limit prosthesis length since longer prostheses can provide running performance advantages. The equations were developed using a white Spanish population; however, validation for other races and geographical groups is limited. This study aimed to determine the validity of the MASH equations for Black and white Americans and whether bias errors between calculated and measured stature were similar between these populations. Sitting height, thigh length, upper arm length, forearm length, and arm span of 1899 male and 1127 female Black and white Americans from the Anthropometric Survey of US Army Personnel database were input into the 6 sex-specific MASH equations to enable comparisons of calculated and measured statures within and between Black and white groups. Two of 12 MASH equations validly calculated stature for Black Americans and 3 of 12 equations were valid for white Americans. Bias errors indicated greater underestimation or lesser overestimation of calculated statures in 10 equations for Black compared to white Americans and in 2 equations for white compared to Black Americans. This study illustrates that race and geography impact the validity of MASH equations.

The perceived value of athlete monitoring systems (AMS) has recently been questioned. Poor perceptions of AMS are important, because where practitioners lack confidence in monitoring their ability to influence programming, and performance is likely diminished. To address this, researchers have primarily sought to improve factors related to monitoring metrics, e.g., validity rather than socio-environmental factors, e.g., buy-in. Seventy-five practitioners (response rate: n = 30) working with Olympic and Paralympic athletes were invited to take part in a survey about their perceptions of AMS value. Fifty-two per cent (n = 13) was confident in the sensitivity of their athlete self-report measures, but only 64% (n = 16), indicated their monitoring was underpinned by scientific evidence. A scientific base was associated with improved athlete feedback (rS (23) = 0.487, p =0.014*) and feedback correlated with athlete monitoring adherence (rS (22) = 0.675, p = <0.001**). If athletes did not complete their monitoring, 52% (n = 13) of respondents felt performance might be compromised. However, most respondents 56% (n = 14), had worked with internationally successful athlete(s) who did not complete their monitoring. While AMS can be a useful tool to aid performance optimisation, its potential value is not always realised. Addressing socio-environmental factors alongside metric-factors may improve AMS efficacy.

BACKGROUND: In Paralympic sports, classification ensures fair competition by grouping athletes based on their impairments. The International Paralympic Committee has provided scientific principles to guide evidence-based classification procedures. In Paralympic Powerlifting, athletes compete in one class, divided by sex and bodyweight categories, overlooking impairment impact on performance. OBJECTIVE: This study aimed to establish a consensus among international Paralympic powerlifting experts regarding classification and performance issues to guide future research. METHODS: A two-round Delphi study was conducted involving 26 experts. The study sought to identify the adequacy of the current classification and competition systems, explore the impact of various impairments, and lay the initial groundwork for a performance determinants model. RESULTS: Experts agreed that existing classification and competition systems in Paralympic powerlifting do not align with Paralympic standards. Impairments from neurological conditions and those causing anthropometric changes were suggested to have opposing performance impacts. Initial directions for a performance determinants model were outlined, focusing on arm and bar kinematics, anthropometry, and body composition. CONCLUSIONS: This study underscores the need for comprehensive research in Paralympic powerlifting, revealing critical discrepancies between current classification system and Paralympic standards. Insights into the multifaceted relationship between impairments and performance are provided to shape the future of Paralympic powerlifting research.

Wearable electronic devices are being used to evaluate movement patterns, track workload, prevent injuries, and optimize performance in athletes. Para athletes have unique characteristics to consider separately from the general population. One such difference in competitive parasports includes consideration of athlete classification systems. These sport-specific classification systems consider athletes' eligible medical conditions that lead to permanent physical, visual, and/or intellectual impairments and objectively evaluate the impact of their impairments on sport functions. Para athletes are assigned sport classes and compete with athletes of similar functional levels. This promotes equitable opportunities to compete while minimizing the effect their impairment has on their sport performance. With recent reports of misrepresentation or incorrect and unfair classification providing unfair advantages to some athletes, parasports classification has been controversial. Having an objective, evidence-based, and fair classification system in parasports is critical to maintain the integrity of parasports competition. Wearable electronic devices have potential to provide more objective analysis of movement patterns in para athletes to assist in sport classification. This review identifies and analyzes the available literature on wearable electronic technology and its role in parasports classification. A comprehensive PubMed and Google Scholar search identified six articles included in this review. These studies used inertial sensors, motion capture systems, or surface electromyography in wheelchair basketball, rugby, tennis, sit skiing, and boccia. This review identifies the potential value of wearable electronic devices to assist in parasports classification. Additional studies are needed to create standardized protocols for each sport and sensor type.
