Incidence of injury and illness at the Beijing 2022 Paralympic Winter Games held in a closed-loop environment: a prospective cohort study of 7332 athlete days.

OBJECTIVE: To describe the epidemiology of injuries and illnesses sustained during the Beijing 2022 Paralympic Winter Games, organised in a closed-loop environment to adhere with COVID-19 restrictions. METHODS: Injuries and illnesses from all teams were recorded on a daily basis by team medical staff on a web-based form and by local organising committee medical (polyclinic) facilities and venue medical support. Duplicates recorded on both systems were removed. Incidence of injuries and illnesses are reported per 1000 athlete days (95% CI). RESULTS: 564 athletes (426 male and 138 female) representing 46 countries were monitored for the 13-day period of the Beijing 2022 Paralympic Winter Games (7332 athlete days). The overall incidences were 13.0 injuries (10.6-15.8) and 6.1 illnesses (4.5-8.4) per 1000 athlete days. The incidence of injury in alpine skiing (19.9; 15.2-26.1) was significantly higher compared with Nordic skiing, ice hockey and wheelchair curling (p<0.05), while the incidence of respiratory illness was significantly higher in Nordic skiing (1.6; 0.9-2.9) compared with alpine skiing, ice hockey and snowboarding (p<0.05). CONCLUSION: The incidence of both injury and illness at the Beijing 2022 Games were the lowest yet reported in the Paralympic Winter Games. The incidence of injury was highest in alpine skiing. These findings underscore the importance of ongoing vigilance and continued injury risk mitigation strategies to safeguard the well-being of athletes in these high-risk competitions. Respiratory illnesses were most commonly reported in Nordic skiing, which included the three cases of COVID-19 recorded at the games.

Handbike configurations and the prevalence of experienced sitting and riding-related problems in recreational handcyclists training for the HandbikeBattle.

Implications for rehabilitationA large variety in handbike configurations is seen in recreationally-active handcyclists.Although the majority of the recreationally-active handcyclists seemed to be satisfied with their handbike configurations, 31-50% of them thought that their handbike configuration could be improved.Evidence-based guidelines for handbike fitting should be developed in the future.

Musculoskeletal Pain, Mood, and Sports Injury in Wheelchair Power Soccer Players.

CONTEXT: Wheelchair Power Soccer (WPS) is the only team sport that allows the participation of people with severe physical disabilities who require the daily use of motorized wheelchairs. These individuals may live with chronic pain due to the characteristics of the disabilities and treatments, interfering with their health and limiting their participation in sports. OBJECTIVES: To investigate the prevalence of musculoskeletal pain and its relationship with mood in WPS players and to analyze the incidence of traumatic injuries during a championship. METHODS: A prospective, longitudinal study was carried out on 30 WPS athletes (93.33% male) with a mean (SD) (range) age of 22.37 (9.79) (47) years. Data collection was performed during a South American WPS Championship lasting 3 days, with: investigation of the presence of musculoskeletal pain and mood through a questionnaire; investigation of the occurrence of traumatic injuries through match observation; and confirmation of the occurrence of traumatic injuries through access to medical department records. RESULTS: About 30% (n = 9/30) of the sample presented some pain on the day of evaluation, with an intensity of 5.67 (3.35) (10) points on the visual analog scale. The most common regions of pain were the lower back (13.3%, n = 4/30), thoracic (10%; n = 3/30), and cervical (10%; n = 3/30) areas of the spine. A total of 46.7% (n = 14/30) reported pain in the month before data collection but of less intensity (2.56 [4] [10] points), the most common regions being the lower limbs (20%; n = 6/30) and cervical spine (20%; n = 6/30). Among the between-group comparisons (ie, participants with pain vs without pain), no relationship was observed between mood state and pain. No traumatic injuries were identified during the competition. CONCLUSION: The presence of musculoskeletal pain was common in WPS players, but it was not related to mood. As no traumatic injuries were observed during the championship, this modality seems to be safe for people with physical disabilities in general.

Injury incidence according to athlete impairment type during the 2012 and 2016 Summer Paralympic Games: a combined analysis of 101 108 athlete days.

OBJECTIVES: The relationship between sport-related injuries and Para athlete impairment type has not yet been comprehensively studied. This study aimed to describe injury incidence according to athlete impairment type during the London 2012 and Rio 2016 Summer Paralympic Games, by sex, age, Games period, chronicity and anatomical area. METHODS: A combined analysis of 7222 athletes was conducted comprising 101 108 athlete days, using pooled data. Internet sources were used to identify impairments of registered athletes. Impairment types: brain disorders (BD), limb deficiency, neuromuscular disorders (NMD), spinal cord-related disorders, visual impairment (VI) and 'all others' (OTH: impaired passive range of movement, intellectual impairment, leg length difference, short stature and unknown impairments). Results by impairment type are reported as univariate unadjusted incidences (injuries/1000 athlete days; 95% CIs). Statistical significance between impairment types was determined when 95% CIs did not overlap. RESULTS: The overall crude unadjusted incidence of injury was 11.1 (95% CI 10.4 to 11.9), significantly higher in VI (13.7 (95% CI 11.0 to 15.7)) and NMD (13.3 (95% CI 11.1 to 16.1)) compared with BD (9.1 (95% CI 7.7 to 10.8)). Acute (sudden onset) (8.6 (95% CI 7.3 to 10.1)) and lower limb (6.6 (95% CI 5.4 to 8.1)) injuries were higher among athletes with VI, while athletes with NMD had a higher incidence of repetitive (gradual onset) (5.9 (95% CI 4.3 to 8.0)) and upper limb (6.9 (95% CI 5.2 to 9.0)) injuries compared with other impairments. CONCLUSIONS: Incidence and type of injuries differed between athlete impairment types. Athletes with VI or NMD sustained the highest incidence of injury, and athletes with BD had the lowest. Findings of this study can inform the management of competition-related injuries in Para athletes.

Sports-related dental injuries and oral health status among Malaysian para-athletes: A cross-sectional study.

BACKGROUND: Athletes with disabilities may be at an even greater risk of orofacial trauma than their counterparts, and the risk may vary depending on the type of sports. This study aimed to assess the incidence of sports-related dental injuries and oral health status among Malaysian para-athletes. METHODS: A questionnaire survey was conducted to assess self-reported dental injuries and knowledge of their management. An intraoral examination was performed using the decayed, missing, and filled teeth (DMFT) index following the World Health Organization guidelines. RESULTS: A total of 61 para-athletes (men = 90.16%, n = 55; women = 9.84%, n = 6) from different sports categories with different disabilities randomly participated in this study. The incidence of self-reported dental injuries was 18.0% (n = 11), with the most common injury being crown tooth fracture (72.7%) and lip laceration (63.6%). However, the majority of the athletes (70.5%, n = 43) did nothing after experiencing dental trauma, and 82.0% (n = 50) were unaware of the immediate management of dental trauma. Based on the intraoral examination, only 9.8% (n = 6) of the athletes had perfectly sound teeth. The mean total DMFT index was 3.49 ± 2.371, while the mean DMFT index for decayed, missing, and filled teeth was 1.28 ± 1.293, 0.74 ± 0.705, and 1.48 ± 1.120, respectively. The mean DMFT index for decayed, missing, and filled teeth and total DMFT index significantly differed among the types of disabilities (P < .05) but not between the sexes (P > .05). CONCLUSION: The most commonly reported injuries among para-athletes are crown tooth fractures and lip lacerations. The total DMFT index among para-athletes is moderate, emphasising the need for improvements.

Exploring the Experiences and Perceptions of Adults With Spinal Cord Injury or Disease Aged 50 Years or Older on Participation in Sports.

Background: Sports are physical activities that provide physical, psychological, and social benefits for individuals with spinal cord injury/disease (SCI/D). However, most sports research has been completed on individuals with SCI/D who are aged >50 years, even though the majority of people with SCI/D are aged >50 years. Despite substantial evidence supporting sports for older adults not living with a disability, there is currently no research examining the impact of sports for adults with SCI/D aged ≥50 years. Objectives: To explore the perceptions and experiences of individuals with SCI/D aged 50 years or older who participate in sports in the community. Methods: Fifteen adults with SCI/D aged ≥50 years who participated in community-based sports were interviewed. Interviews were audio-recorded and transcribed verbatim. Conventional content analysis was applied to the data. Results: The overarching theme identified was that sports are fun and adaptable physical activities that have the potential to optimize physical, psychological, and social health in all people with SCI/D, regardless of age. Within this overarching theme, six categories surfaced: (1) importance of participating in sports later in life, (2) prioritizing health over performance, (3) uncertainties about participating in sports later in life, (4) reflections on participating in sports later in life, (5) beliefs on alternative sports involvement, and (6) advice for other aging adults with SCI/D considering sports. Conclusion: Sports are perceived to provide physical, psychological, and social benefits for individuals with SCI/D aged 50 years or older. Findings will inform the development of future adaptive sports programs for older individuals with SCI/D.

El deporte paralímpico en Chile: resultados históricos de las participaciones en los Juegos Paralímpicos de Invierno y Verano

Esta investigación tuvo como objetivo relatar la evolución del movimiento paralímpico y su vínculo con el escenario político nacional e internacional. Los Juegos Paralímpicos de Verano hicieron su debut en 1960, mientras que Chile participó por primera vez en 1992. Por otro lado, los Juegos Paralímpicos de Invierno comenzaron en 1976, y la primera participación chilena en este evento se produjo en 2002. Para el desarrollo del estudio se utilizó un análisis documental, donde se analizaron las convocatorias oficiales de las delegaciones chilenas, junto con las planillas de resultados generales obtenidos en los Juegos Paralímpicos, se extrajo de los documentos: el número de atletas participantes de ambos sexos y deportes, información que posteriormente fue agrupada en presencia o no de medallas y tipo de medalla obtenida y, a partir de aquello, se analizó por tipo de discapacidad y año de participación. A través de los años, Chile vivenció constantes procesos y cambios en los periodos de gestión, a esto se suma la promulgación de leyes, tanto nacionales como internacionales, junto con la constante ayuda recibida de distintas agrupaciones privadas y gubernamentales, resultando en un paulatino incremento de deportistas paralímpicos, situación que colaboró en gran medida con el desarrollo integral del movimiento paralímpico chileno hasta lo que es en la actualidad; este crecimiento facilitó resultados exitosos, como el obtenido en el año 2012 con la conquista de la primera medalla paralímpica de Chile, llegando a un total de siete medallas distribuidas en cuatro deportes en los Juegos Paralímpicos Tokio 2020, quedando situado en el ranking paralímpico en la cuadragésima quinta posición.

The aim of this paper was to describe the evolution of the Paralympic movement and its connection with the national and international political scenario. The Summer Paralympic Games made their debut in 1960, while Chile first participated in 1992. On the other hand, the Winter Paralympic Games began in 1976, and Chile's first participation in this event occurred in 2002. A documentary analysis was conducted for the study, in which the official documents of the Chilean delegations were analyzed, along with the overall results obtained in the Paralympic Games. The documents provided information on the number of participating athletes of both genders, results and sports. This information was later grouped based on the presence or absence of medals and the type of medal obtained. It was further analyzed by type of disability and year of participation. Over the years, Chile experienced constant processes and changes in management, in addition to the enactment of laws, both national and international. The constant support received from various private and governmental organizations contributed to the gradual increase in paralympic athletes, which greatly facilitated the overall development of the Chilean Paralympic movement to its current state. This growth led to successful outcomes, such as Chile's 1st Paralympic medal in 2012, and the country has now achieved a total of 7 medals in 4 disciplines in Paralympic Games Tokyo 2020, placing it in the 45th position in paralympic medal board.

O presente trabalho tem como objetivo relatar a evolução do movimento paralímpico e sua relação com o cenário político nacional e internacional. Os Jogos Paralímpicos de Verão fizeram sua estreia em 1960, enquanto o Chile participou pela primeira vez em 1992. Por outro lado, os Jogos Paralímpicos de Inverno começaram em 1976, e a primeira participação chilena neste evento ocorreu em 2002. O estudo foi realizado através de análise documental, de onde foram extraídas informações sobre as delegações chilenas, juntamente com as planilhas de resultados gerais obtidos dos Jogos Paralímpicos. As variáveis registradas foram número de atletas participantes de ambos os sexos, modalidades e esportes. As informações posteriormente foram agrupadas em quantidade de medalhas e tipo da medalha obtida, sendo analisadas por tipo de deficiência e ano de participação. Ao longo dos anos, o Chile experimentou constantes processos e mudanças nos períodos de gestão, como a promulgação de leis, tanto nacionais como internacionais, juntamente com a ajuda constante recebida de diferentes grupos privados e governamentais, resultando em aumento de atletas paralímpicos, situação que contribuiu com o desenvolvimento integral do movimento paralímpico chileno. Este crescimento facilitou resultados exitosos, como o obtido em 2012 com a conquista da primeira medalha paralímpica do Chile, alcançando hoje um total de 7 medalhas distribuídas em 4 disciplinas em Tóquio 2022, colocando-se na quadragésima quinta posição do quadro de medalhas.

Incidence of injury and illness among paediatric Team USA athletes competing in the 2020 Tokyo and 2022 Beijing Olympic and Paralympic Games.

Objective: To describe the incidence of injuries and illnesses among paediatric Team USA athletes competing in the Tokyo 2020 Olympic and Paralympic Games, and the 2022 Beijing Olympic and Paralympic Games. Methods: An electronic medical record system documented all injuries and illnesses that occurred while competing in the four Games periods. Incidence (IR) with 95% CI per 1000 athlete days were calculated for both injuries and illnesses. Incidence rate ratios (IRR) were calculated to compare injury and illness rates based on age (paediatric vs non-paediatric) sex, Games period and sport type. Results: Two hundred paediatric athletes (age range, 15-21 years) competed across the four Games periods, representing 16.1% of all Team USA athletes. The overall injury IR (95% CI) was 13.4 (9.8 to 18.1), and the overall illness IR was 5.5 (3.3 to 8.7). There were no differences in incidence between paediatric and non-paediatric athletes for either injury (IRR (95% CI): 0.9 (0.6 to 1.2)) or illness (IRR (95% CI): 0.9 (0.5 to 1.5)). Female paediatric athletes were more likely to sustain an injury compared with male paediatric athletes (IRR (95% CI): 2.4 (1.1 to 5.3)). The most common mechanism of injury was gradual onset (IR, 4.3 (2.3 to 7.2)), and injuries most commonly occurred during practices (IR, 7.0 (4.5 to 10.5)). Conclusion: Paediatric athletes account for a substantial proportion of Team USA athletes. It is essential that paediatric sports medicine experts are included in the medical team given that paediatric Team USA athletes are just as likely as their adult teammates to sustain an injury or illness.

Wheelchair basketball, health, competitive analysis, and performance advantage: a review of theory and evidence.

The purpose of this study was to review the various risks and benefits of wheelchair basketball (WB) and explore some of the research which outlines factors that influence WB player performance and conditioning. WB offers several physical and psychological advantages. Physically, it can improve muscle strength, endurance, and cardiovascular fitness while decreasing the prevalence of chronic physical disorders. From a psychological standpoint, WB has been shown to alleviate anxiety and feelings of depression while also creating and improving social relationships. Despite the many benefits, WB can cause injuries, particularly in the upper extremities, and preventative measures should be employed. WB necessitates intense intermittent efforts and athletes must maintain excellent cardiovascular fitness, strength, and muscular endurance. Healthy sleeping patterns have also been shown to improve performance in WB players. Wheelchair mobility and biomechanical variables as well as wheelchair size and weight appear to be critical success elements in WB. WB can be a powerful tool for coaches and therapists to boost the physical and emotional health of individuals with disabilities and motivate them to participate in team-based sport.

The impact of lower-limb function on upper-limb pull and push strength in elite handcycling athletes.

This study investigated the impact of performing a closed kinetic chain with the lower limbs on isometric upper-limb pull and push strength. Sixty-two elite handcyclists were assessed with the Manual Muscle Test and allocated to groups with partial to normal (LLF) or no lower-limb (no-LLF) function. Both groups performed upper-limb strength measurements under two kinetic-chain conditions. During the closed-chain condition, the lower limbs were attached to two footrests, providing horizontal and vertical support. During the open-chain condition, the footrests were removed and the limbs were supported vertically by a horizontal plate. Repeated-measures ANOVA were conducted to investigate main effects (open vs. closed chain, LLF vs. no-LLF) and their interaction. During pull, LLF performed better (p < 0.001, +11%) by pushing against the footrests. However, this increase in pulling strength during a closed-chain condition was not observed in the no-LLF. Therefore, findings suggest an advantage for the least impaired athletes by being able to perform lower-limb closed chains during pulling. Handcyclists with LLF can maximise pulling performance by adjusting the footrests. The classification system should consider the implications of these findings on the allocation of athletes with different levels of LLF and/or on the equipment regulation.

Anthropometric Characteristics, Handgrip Strength, and Upper Limb Asymmetries in Highly Trained Chilean Shot Put Para-Athletes / Características Antropométricas, Fuerza de Prensión Manual y Asimetrías de Miembros Superiores en Para-Atletas Chilenos de Lanzamiento de Bala Altamente Entrenados

SUMMARY: Anthropometric characteristics, including body size, shape, and composition, can have a significant impact on sports performance due to their influence on various physiological and biomechanical factors. However, limited research has been conducted on the anthropometric characteristics of highly trained throwing para-athletes. The purpose of this study was to describe the anthropometric characteristics, handgrip strength, and upper limb bilateral asymmetries of highly trained Chilean shot put para-throwers. Five male Chilean shot put para-athletes (average age of 38.8 ± 7.7 years) were assessed for their anthropometric characteristics, including skinfold thickness at six anatomical sites, girth at five sites, and bone breadth at two sites. Handgrip strength and bilateral asymmetries were also measured. The body mass and height of the athletes were found to be 90.5 ± 5.1 kg and 179.1 ± 8.9 cm, respectively. The athletes were found to have an endo-mesomorph somatotype (4.4-6.9-1.0) with high levels of fat mass (25.7 ± 2.8 %) and skeletal muscle mass (39.1 ± 3.7 %). The handgrip strength of the athletes was found to be 66.4 ± 6.7 kg with a bilateral asymmetry of 6.5 ± 6.2 %, with the dominant hand showing greater strength. The results indicate that the shot put para-athletes have a somatotype characterized by increased muscularity and body fat, along with a considerable stature. Although handgrip strength was found to be high, the athletes showed bilateral asymmetry, which requires further investigation to determine the cause and implications.

Las características antropométricas, incluido el tamaño, forma y composición del cuerpo, pueden tener un impacto significativo en el rendimiento deportivo debido a su influencia en diversos factores fisiológicos y biomecánicos. Sin embargo, las investigaciones sobre las características antropométricas para-atletas de lanzamiento altamente entrenados son limitadas. El propósito de este estudio fue describir las características antropométricas, la fuerza de prensión manual y las asimetrías bilaterales de miembros superiores de paralanzadores chilenos altamente entrenados en lanzamiento de la bala. Se evaluaron las características antropométricas de cinco atletas masculinos chilenos de lanzamiento de bala (edad promedio de 38,8 ± 7,7 años), incluido el grosor de los pliegues cutáneos en seis sitios anatómicos, la circunferencia en cinco sitios y la anchura de los huesos en dos sitios. También se midieron la fuerza de prensión manual y las asimetrías bilaterales. Se encontró que la masa corporal y la altura de los atletas eran 90,5 ± 5,1 kg y 179,1 ± 8,9 cm, respectivamente. Los atletas tenían un somatotipo endo-mesomorfo (4.4-6.9-1.0) con altos niveles de masa grasa (25.7 ± 2.8 %) y masa muscular esquelética (39.1 ± 3.7 %). Se encontró además que la fuerza de prensión manual de los atletas era de 66,4 ± 6,7 kg con una asimetría bilateral de 6,5 ± 6,2 %, mostrando mayor fuerza la mano dominante. Los resultados indican que los atletas de lanzamiento de bala tienen un somatotipo caracterizado por una mayor musculatura y grasa corporal, junto con una estatura considerable. Aunque se encontró que la fuerza de agarre era alta, los atletas mostraron asimetría bilateral, lo que requiere de más investigaciones para determinar las causa e implicaciones.

Young para-athletes display more hedonic well-being than people with disabilities not taking part in competitive sports: insights from a multi-country survey.

Hedonic well-being relates to how individuals experience and rate their lives. People with disabilities due to their pathology may more frequently suffer from anxiety and depressive disorders than their able-bodied counterparts. Sports participation is an essential way to cope with disability. On the other hand, compared with their able-bodied peers, para-athletes undergo a unique series of stressors. Little is known in terms of hedonic well-being in this specific population. We present the results of a multi-country survey of self-perceived hedonic well-being by para-athletes of different sports disciplines and a control group (disabled individuals not playing competitive sports), using the "Psychological General Well-Being Index" (PGWBI). We included 1,208 participants, aged 17.39 years, 58.4% male, 41.6% female, and 70.3% para-athletes. Para-athletes exhibited higher well-being than disabled people, for all domains of the PGWBI scale. The nature of disability/impairment was significant, with those with acquired disability reporting lower well-being. Those taking part in wheelchair basketball, para-athletics, and para-swimming competitions had a higher likelihood of reporting well-being, whereas those engaged in wheelchair rugby exhibited lower well-being compared with controls. This large-scale investigation can enable a better understanding of the self-perceived hedonic well-being of disabled people.

Heat preparedness and exertional heat illness in Paralympic athletes: A Tokyo 2020 survey.

Paralympic athletes may be at increased risk for exertional heat illness (EHI) due to reduced thermoregulatory ability as a consequence of their impairment. This study investigated the occurrence of heat-stress related symptoms and EHI, and the use of heat mitigation strategies in Paralympic athletes, both in relation to the Tokyo 2020 Paralympic Games and previous events. Paralympic athletes competing in Tokyo 2020 were invited to complete an online survey five weeks prior to the Paralympics and up to eight weeks after the Games. 107 athletes (30 [24-38] years, 52% female, 20 nationalities, 21 sports) completed the survey. 57% of respondents had previously experienced heat-stress related symptoms, while 9% had been medically diagnosed with EHI. In Tokyo, 21% experienced at least one heat-stress related symptom, while none reported an EHI. The most common symptom and EHI were, respectively, dizziness and dehydration. In preparation for Tokyo, 58% of respondents used a heat acclimation strategy, most commonly heat acclimatization, which was more than in preparation for previous events (45%; P = 0.007). Cooling strategies were used by 77% of athletes in Tokyo, compared to 66% during past events (P = 0.18). Cold towels and packs were used most commonly. Respondents reported no medically-diagnosed EHIs during the Tokyo 2020 Paralympic Games, despite the hot and humid conditions in the first seven days of competition. Heat acclimation and cooling strategies were used by the majority of athletes, with heat acclimation being adopted more often than for previous competitions.

Dietary assessment of 101 para-athletes from team and individual sports.

Assessing the usual food intake of para-athletes enables knowledge and description of nutrient intakes, providing insight into the potential nutritional status of para-athletes and may help tailor dietary intake to their specific training needs. This study aimed to evaluate the usual intake of macronutrients and food groups and meal food patterns of athletes with a disability. We also compared dietary intake data between team and individual sport para-athletes. One hundred and one athletes with a disability from 13 Paralympic disciplines living in Brasília, Federal District, Brazil were included. Food intake was estimated from two or four non-consecutive 24-h food recalls in which para-athletes reported all food, beverages, and supplements consumed in the previous 24-h. Dietary intake analysis was performed by implementing the National Cancer Institute (NCI) method to calculate the macronutrient and food group usual intake. Macronutrient intakes were compared to Acceptable Macronutrient Distribution Ranges for the general population and food group intakes were compared to the 2008 Brazilian National Dietary Guidelines. Para-athletes consumed a low-carbohydrate, adequate protein, high-fat diet. There was no significant difference in macronutrient intake distribution between team sport and individual sport para-athletes. Most para-athletes had three main meals during the day. The prevalence of inadequate fruit servings in the middle and highest energy intake tertiles was significantly higher in team sport para-athletes (92.5% and 98.4%) than in individual sport para-athletes (90.8% and 65.5%), respectively. The prevalence of inadequate vegetable servings was significantly higher between team and individual para-athletes for the middle energy intake tertiles. Para-athletes generally consumed an imbalanced diet, which is a cause for concern given their additional physiological demands and specific training needs.

Actigraphy-Based Sleep Parameters in Wheelchair Basketball Athletes: Influence of Training and Competition Load.

Objective This study aimed to analyze the actigraphy-based sleep parameters in wheelchair basketball (WB) athletes during the 3 weeks leading up to the playoffs, the week of playoffs, and the week after playoffs. Secondarily, the relationship between training load, sleep, and recovery was evaluated. Methods During 5 consecutive weeks, 10 male elite WB athletes wore a triaxial accelerometer. The session rating of perceived exertion (sRPE) and athletes' quality of recovery were also measured. Results There were no significant differences ( p > 0.05) in any of the studied parameters between the 3 weeks leading up to the playoffs, the week of playoffs, and the week after playoffs. No significant relationship between training load, sleep parameters, and recovery values was detected. Discussion The WB competition does not affect sleep quantity and quality.

Well-being and quality of life in people with disabilities practicing sports, athletes with disabilities, and para-athletes: Insights from a critical review of the literature.

Global well-being (GWB) is a complex, multi-dimensional, and multi-faceted construct that can be explored from two different, but often overlapping, complementary perspectives: the subjective and the objective ones. The subjective perspective, in turn, is comprised of two dimensions: namely, the hedonic and the eudaimonic standpoints. Within the former dimension, researchers have developed the concept of subjective hedonic well-being (SHWB), whereas, within the latter, they have built the framework of psychological and social well-being (PSWB). Disabled people have poorer well-being due to their pathology and may more frequently suffer from anxiety and depressive disorders than their able-bodied counterparts. Sports participation is an essential way to cope with disability. On the other hand, compared with their able-bodied peers, athletes with disabilities and para-athletes undergo a unique series of stressors. Little is known in terms of hedonic and eudaimonic well-being and quality of life in this specific population. Here, we review the literature, with an emphasis on the current state-of-art and gaps in knowledge that need to be addressed by future research. High-quality, large-scale investigations are needed to have a better understanding of the self-perceived (hedonic) and objective (eudaimonic) well-being and quality of life of disabled people practicing sports, athletes with disabilities, and para-athletes.
