Effects of combined training in individual with Intellectual and Developmental Disabilities: a systematic review and meta-analysis of randomized controlled trials.

PURPOSE OF THE ARTICLE: This study aims to evaluate the literature, peer-reviewed clinical trials investigating the effects of combined exercise interventions on individuals with Intellectual and Developmental Disabilities. MATERIALS AND METHODS: Various databases, using various descriptors and Boolean operators were utilized. RESULTS: Eight studies meet the eligibility criteria. Regarding the anthropometric measures/body composition variable, the meta-analysis revealed that combined physical exercise did not have a significant effect (standard mean difference (SMD) = -0.16; 95% CI, -0.34 to 0.03; Z = 1.68; p = 0.09). For the lipid profile variable, the combined exercise interventions did not show a significant effect (SMD = -0.07; 95% CI, -0.43 to 0.29; Z = 0.38; p = 0.71). Combined exercise training had a significant effect on increasing functional capacity (SMD = 0.28; 95% CI, 0.01 to 0.54; Z = 2.03; p = 0.04), cardiorespiratory function (SMD = 0.80; 95% CI, 0.34 to 1.26; Z = 3.41; p ≤ 0.001), and strength (SMD = 0.77; 95% CI, 0.45 to 1.08; Z = 4.78; p ≤ 0.001). CONCLUSIONS: Participants from the intervention group that took part in combined exercise training showed a higher probability of improving their functional, cardiorespiratory, and strength capacity compared to the control group.

This study synthesises the literature, peer-reviewed clinical trials investigating the effects of combined exercise interventions on individuals with Intellectual and Developmental Disabilities.Participants who performed combined physical exercise were more likely to improve their functional, cardiorespiratory and strength capacity compared to the control group.Professionals (e.g., rehabilitation technician, exercise technician) responsible for planning interventions for people with IDD should consider the results of this study when planning their interventions, particularly regarding the prescription of physical exercise, as well as monitoring training and several important variables that can be enhanced by regular physical exercise.Organisations that provide support to people with IDD (support or social solidarity institutions) should also consider the results of this study, to provide the necessary conditions (materials, spaces or human resources) so that professionals could plan this type of intervention in the most appropriate and adapted way possible for the individual.

Physical Fitness of the Older Adult Community Living in Leiria, Portugal.

This study aimed to achieve two primary objectives. Firstly, to compare physical fitness levels based on sex, age groups, and body composition. Secondly, to examine physical fitness of the older adults against criterion-referenced fitness standard values using a representative sample from the district of Leiria in Portugal, a region undergoing exponential population growth, including a rise in the elderly population. Data from cross-sectional assessments of the Portuguese older adult community living in the Municipality of Leiria from 2014 to 2022 were collected. This study comprised a sample of 664 community-dwelling older adults (female = 480; male = 184) aged between 60 and 90 years (M = 70.34; SD = 12.67). Participants had a body mass ranging from 45 kg to 122 kg (M = 71.48; SD = 12.34) and a height ranging from 1.30 m to 1.89 m (M = 1.59; SD = 0.08). The Senior Fitness Test battery was used to evaluate parameters of physical fitness, body mass index was calculated, and abdominal circumference was measured. Females displayed a tendency to greater physical fitness compared to males, specifically in terms of lower and upper body flexibility compared to older male adults (p < 0.05). In addition, sexagenarian and older adults with normal weight tended to display greater physical fitness compared to septuagenarian and octogenarian, and overweight adults and those with obesity (p < 0.05), respectively. Information concerning physical fitness is crucial for guiding policymakers and other stakeholders in Leiria for the promotion of healthy aging among the older adult community. Furthermore, this study has established the preliminary reference standards for physical fitness, serving as a tool to promote healthy aging among Portuguese older adults residing in Leiria.

Effect of a 12-Week Strength Training Program on Muscle Strength Measures of Institutionalized Older Adults-A Pilot Study.

Institutionalized older adults are characterized by high levels of dependence and low levels of physical activity compared to those living in the community. This combination of factors leads to an increased risk of loss of muscle mass. Sarcopenia can be countered through strength training. The aim of the present study was to evaluate the effect of a strength training program on the physical fitness of institutionalized older adults. This study included a sample of 31 institutionalized older adults (20 females, 11 males) aged between 65 and 96 years (M = 81.64, SD = 8.67). Participants reported an average institutionalization duration of 2.43 years (SD = 2.20), ranging from half a year to ten years. A 12-week strength training program was implemented, with sessions held twice a week. Strength fitness was assessed through the following parameters: handgrip strength, upper limb muscular endurance, lower limb muscular endurance, agility and balance, body mass index, and waist circumference. The results demonstrated that a 12-week strength training program improved physical fitness in terms of lower limb muscular endurance, upper limb muscular endurance, agility, and dynamic balance (p < 0.05).

Physical Activity, Anxiety, Depression, and Body Image in Trans Individuals: An Exploratory Study.

Physical activity (PA), mental health, and body image are some important health topics in the transgender population that have been recently discussed and appear to play a crucial role in the quality of life of the trans population. This study aims to elucidate the complex interplay of these variables and their implications for the well-being of trans individuals. METHODS: In a cross-sectional study, 75 Portuguese transgender individuals (M = 23.68; SD ± 6.59) were recruited to participate in this study. The participants completed three questionnaires related to the assessment of physical activity (IPAQ), depressive and anxious symptomatology (HADS), and satisfaction with body image (BISQp). RESULTS: Trans individuals showed a total energy expenditure of 3316.40 metabolic equivalent tasks (METS), had a moderate level of anxiety symptomatology, and low levels of satisfaction with body image. Satisfaction with body image was negatively associated with anxiety (r = -0.441, p < 0.01) and depression symptomatology (r = -0.600, p < 0.01). CONCLUSIONS: The implementation of inclusive programs that promote body acceptance and coping strategies, particularly within the context of physical exercise, may help alleviate distress related to body image dissatisfaction while also addressing underlying anxiety and depression symptoms.

Initial Validation of the Coach-Athlete Relationship Questionnaire in a Sample of Portuguese Athletes.

Our primary objectives in this study were to translate and provide psychometric support for the Coach Athlete Relationship Questionnaire (CART-Q) Portuguese version, assess its invariance across sex, and explore its nomological validity in relation to enjoyment. Our sample participants were 470 athletes (226 females, 244 males) aged between 16 to 39 years from various individual and team sports. We found that the translated Portuguese version of the CART-Q exhibited satisfactory test-retest reliability and can serve as a reliable tool for evaluating the core constructs of the coach-athlete relationship - closeness, commitment, and complementarity. Moreover, this instrument showed evidence of nomological validity through significant positive correlations between its underlying factors and athletes' enjoyment with their sport. The proposed model for explaining item variance was also found to be invariant between male and female respondents. We recommend further use of this instrument in research and practical applications.

Gender Differences in Anthropometric, Functional Capacity Measures and Quality of Life in Individuals with Intellectual and Developmental Disabilities.

The aim of the of the current investigation was to investigate the possible differences concerning males and females in anthropometry, body composition, functional capacity, strength and quality of life variables. After obtaining signed informed consent, 37 participants (18 males; 19 females), with mean age of 39.08 and standard deviation of 11.66 years, voluntarily participated in this study. Anthropometry, body composition, functional capacity, strength, and quality of life were assessed using validated and reliable instruments and tests for this population. The males and females were compared using a Mann-Whitney U signed rank test. Significant differences were detected among the following variables, height (p = 0.028), body mass index (p = 0.033), fat mass (p = 0.002), muscle mass (p ≤ 0.001), phase angle (p = 0.005), medicine ball throwing strength (p = 0.010), and peak toque left knee (p = 0.028), with males showing better results in all the variables. The sample in this study showed differences in the anthropometric, composition, and strength variables. Studying this population can help ensure that everyone has equal access to services and adequate support for their personal needs, improving their quality of life.

Physical Activity, Quality of Live and Well-Being in Individuals with Intellectual and Developmental Disability.

The practice of physical activity, exercise and sport has many benefits for the general population, but studies on the population with intellectual and developmental disabilities (IDD) are scarce and inconclusive. The aim of this systematic review is to analyze the state of the art on the role of physical activity, exercise and sport in the quality of life and well-being of people with IDD, seeking to understand the current panorama in this area and provide answers to these questions. The research was carried out between July and October 2023 using three databases: PubMed, Web of Science and Scopus. Fifteen articles met the eligibility criteria for this study, and these were methodologically assessed using the Downs and Black scale (1998). Higher values were identified in the total quality of life score and some domains of this variable (e.g., personal development, physical well-being and emotional well-being), in satisfaction with life and in the perception of well-being in individuals with IDD who have enjoyed or are involved in physical activity, physical exercise and/or sports programs. Thus, according to the studies included in this systematic review, we can conclude that the practice of physical activity, physical exercise and sport seems to contribute to improving the quality of life and well-being of people with IDD. Despite the growing research interest in this area, there is still a notable lack of studies exploring the impact of these programs, especially sports-based programs, on quality of life and well-being variables in the population under study.

Exploring the relationship across autonomous motivation, affects, and anxiety among gym practitioners during the second COVID-19 lockdown.

The present study explores the association of autonomous motivation and the relationship of positive and negative affect on anxiety levels among individuals engaged in gym practitioners during the second COVID-19 lockdown. A total of 196 exercisers (29.17 ± 10.77) were enrolled in the present study, of which 112 (57.1%) were women and 84 (42.9%) were men. The survey included sociodemographic data, as well as validated instruments measuring autonomous motivation, positive and negative affect, and anxiety states related to the COVID-19 pandemic. The results revealed a positive association between autonomous motivation and positive affect (ß = 0.36, CI 0.12, 0.37; p < 0.001), and a negative association between autonomous motivation and negative affect (ß = - 0.17, CI - 0.31, - 0.01; p = 0.03). Moreover positive, and negative affect are negatively (ß = - 0.33, CI - 0.43, - 0.24; p < 0.001) and positively (ß = 0.72, CI 0.57, 0.82; p < 0.001) associated to anxiety, respectively. Thus, this study appears to emphasize the association of autonomous motivation on affect as a potential buffer against anxiety levels, particularly in a context where practitioners found themselves restricted in their usual gym practices.

Exploring the Dynamics of Athletes' Enjoyment and Self-Determined Motivation, and of the Motivational Climate in Youth Football: A Longitudinal Perspective.

We aimed to explore a short period longitudinal interplay between athletes' enjoyment and their self-determined motivation and motivational climate in youth football. We recruited 109 youth football athletes (79 males, 30 females) through a convenient sampling method. We included individuals within the 12-17-year-old age range, with a mean age of 14.31 (SD = 1.46) years. To examine these proposed associations, we performed hierarchical multiple regression analyses and found that enjoyment at pre-season assessment (T1) and self-determined motivation and a task-involving sport climate at mid-season (T2) were significant predictors of mid-season enjoyment (at T2). However, self-determined motivation and task-involving climate at T1 did not significantly contribute to the model. These findings emphasize the importance of initial enjoyment and an evolved self-determined motivation, and task-involving climate in understanding later enjoyment in sport. Coaches, practitioners, and policymakers should prioritize strategies that enhance intrinsic motivation, provide opportunities for autonomy, and cultivate a supportive and growth-oriented environment.

Exploring the relationship between social support, resilience, and subjective well-being in athletes of adapted sport.

Introduction: Sports participation of people with disabilities provide an improvement in their skills, especially on access to social support, which could improve resilience and well-being. This study aims to analyze the association between types of social support (parents, coach, friend, and best friend), resilience and positive and negative affect, in 105 Portuguese athletes with disabilities aged between 13 and 61 years (32 ± 12.35 years). Methods: Participants answered a short sociodemographic questionnaire, the Portuguese version of the Positive and Negative Affect Schedule, and the Brief Resilience Scale, and a scale for assessing social support from parents, coach, friend, and best friend. Results: Social support provided by the best friend, coach, friends, and parents had a direct effect on resilience and positive and negative affect. Results showed a positive and significant association between resilience and positive affect (r = 0.28; p = 0.004) and a negative association between resilience and negative affect (r = -0.37; p ≤ 0.001). A strong relationship was found between resilience and affect, with no relationship being verified between the sources of social support and resilience or affect, as hypothesized. Discussion: For this group of athletes with disability, more than the social support they may have or may feel, resilience proved to be very important for the consequence of sports practice in terms of subjective well-being.

O exercício físico e a vitalidade: análise multigrupos em função do sexoe experiência da prática / Ejercicio físico y vitalidad: análisis multigrupo según sexo y experiencia de práctica / Physical exercise and vitality: multigroup analysis according to sex and practice experience

La percepción subjetiva de vitalidad es un indicador de bienestar que se puede traducir en una mejor calidad de vida. Un instrumento válido y fiable permitirá a los investigadores medir con precisión la vitalidad en el contexto del ejercicio físico.. Así, el objetivo del presente estudio fue evaluar la validez y fiabilidad de la Subjetive Vitality Scale (SVS) en una muestra portuguesa de practicantes de ejercicio físico según sexo y experiencia de práctica. Los datos se recolectaron de una muestra de un total de 330 adultos (mujeres = 145; hombres = 185). Los participantes tenían entre 18 y 64 años (M = 28.52; DT = 9.86), con una experiencia de ejercicio promedio de 8.14 meses (DT = 6.14), y con una frecuencia semanal de entre 1 y 7 veces (M = 4.42; DT = 1.35). Se realizó un análisis factorial confirmatorio del modelo de medición de seis ítems de la escala y un análisis de invariancia en función del género y la experiencia práctica. También se analizaron los resultados de las correlaciones bivariadas con el fin de evaluar la validez nomológica del instrumento con diversión y con la intención de continuar en la práctica. El modelo de medición SVS demostró un ajuste aceptable en cada una de las muestras y los coeficientes de fiabilidad compuesta fueron adecuados. Las correlaciones indicaron que mayores niveles de vitalidad se asociaron con mayores niveles de diversión e intención de continuar practicando ejercicio físico en el futuro. El modelo de medida demostró ser invariante entre muestras, lo que aporta un mayor sustento a su validez para evaluar la percepción subjetiva de vitalidad en el contexto del ejercicio físico. La SVS parece ser así un instrumento fiable para evaluar la vitalidad, en ambos sexos, así como en personas con diferentes experiencias de práctica. (AU)

The subjective perception of vitality is an indicator of well-being that can translate into improved quality of life. A valid and reliable instrument will allow researchers to accurately measure vitality in the context of exercise. Thus, the objective ofthe present study was to evaluate the validity and reliability of the Subjective Vitality Scale (SVS) in a Portuguese sample of physical exercise practitioners according to gender and practice experience. Data were collected from a sample of a total of 330 adults (women = 145; men = 185). Participants were aged between 18 and 64 years (M = 28.52; SD = 9.86), with a mean exercise experience of 8.14 months (SD = 6.14), and with a weekly frequency of between 1–7 times (M = 4.42; SD = 1.35). A confirmatory factor analysis of the scale's six-item measurement model and an analysis of invariance as a function of gender and practice experience were performed. The results of bivariate correlations were also analyzed toassess the nomological validity of the instrument with enjoyment and with the intention of continuing in practice. The SVS measurement model demonstrated an acceptable fit in each of the samples and the composite reliability coefficients were adequate. Correlations indicated that higher levels of vitality were associated with higher levels of enjoyment and intention to continue to practice physical exercise in the future. The measurement model proved to be invariant between samples, thus adding greater support to its validity to assess the subjective perception of vitality in the context of physical exercise. The SVS thus seems to be a reliable instrument for assessing vitality, in both sexes, as well as in people with different practice experiences. (AU)

A perceção de vitalidade subjetiva é um indicador de bem-estar que se pode traduzir na melhoria da qualidade de vida. Um instrumento válido e fiável irá permitir aos investigadores uma medição precisa da vitalidade no contexto de exercício físico. Desta forma, o objetivo do presente estudo consistiu em avaliar a validade e a fiabilidade da Subjetive Vitality Scale (SVS) numa amostra portuguesa de praticantes de exercício físico em função do sexo e da experiência da prática. Foram recolhidos dados de uma amostra com um total de 330 adultos (mulheres = 145; homens = 185). Os participantes tinham idades compreendidas entre 18–64 anos (M = 28.52; DP = 9.86), com experiência média de exercício de 8.14 meses (DP = 6.14), e com uma frequênciasemanal entre 1–7 vezes (M = 4.42; DP = 1.35). Realizou-se uma análise fatorial confirmatória do modelo de medida de seis itens da escala e uma análise de invariância em função do sexo e experiência da prática. Foram, também, analisados os resultados de correlações bivariadas com o objetivo de avaliar a validade concorrente do instrumento com o divertimento e com a intenção de continuar na prática. O modelo de medida da SVS demonstrou um ajustamento aceitável em cada uma das amostras e os coeficientes de fiabilidade compósita foram adequados. As correlações indicaram que maiores níveis de vitalidade estavam associados a maiores níveis de divertimento e intenção de continuar a praticar exercício físico no futuro. O modelo de medida revelou ser invariante entreamostras, acrescentando, por isso, um maior suporte à sua validade para avaliar a perceção subjetiva de vitalidade em contexto do exercício físico. A SVS parece, assim, ser um instrumento fiável para a avaliação da vitalidade, em ambos os sexos, bem como em pessoas com diferentes experiências de prática. (AU)

A pilot study on fear and risk of fall: The impact of an 8-month multicomponent exercise program in community-dwelling aged adults / Un estudio piloto sobre el miedo y el riesgo de caída: el impacto de un programa de ejercicios de componentes múltiples de 8 meses en adultos mayores que viven en la comunidad / Um estudo piloto sobre medo e risco de queda: o impacto de um programa de exercício multicomponente de 8 meses em adultos idosos residentes na comunidade

Este estudio tuvo como objetivo examinar el impacto del efecto de un programa de ejercicio de componentes múltiples de 8 meses en adultos mayores que viven en la comunidad. Utilizamos una estrategia inclusiva para examinar la viabilidad de un programa de ejercicio de tres veces por semana. Tener más de 60 años, la capacidad de pararse y caminar con o sin equipo de asistencia, ser físicamente inactivo, autorización médica y vivir en la comunidad fueron todos los criterios de elegibilidad. Se utilizaron la prueba Timed-up and Go y la Berg Balance Scale para examinar el riesgo de caídas. Se utilizó la Fall-Efficacy Scale International para examinar el miedo a las caídas. El programa de ejercicio basado en la comunidad involucró a treinta y cinco participantes, la edad promedio fue de 67.54 años (SD = 3.81) y el 71% eran mujeres. Las tasas de asistencia variaron de 76% a 100% en promedio. Hubo una tendencia significativa hacia una mejora clínicamente importante en el timed-up and go test (t = 4.66; p < .001; d = 0.20), escala de equilibrio de Berg (t = -11.20; p < .001; d = 1.47) y escala internacional de eficacia contra caídas (t = 5.81; p < .001; d = 0.88). Este estudio ha proporcionado evidencia preliminar de que un programa de ejercicio de bajo costo basado en la comunidad de 8 meses puede ser efectivo para mejorar la agilidad, el equilibrio y disminuir el miedo a caerse en las personas mayores.

The objective of this study was to investigate the impact of an 8-month multicomponent exercise program in community-dwelling older adults. A comprehensive approach was employed to assess the feasibility and effectiveness of a thrice-weekly exercise intervention. Aged over 60 years, the capacity to stand and walk with or without assistive equipment, being physically inactive, medical clearance, and living in the community were all eligibility criteria. The Timed-up and Go test and Berg Balance Scale were used to examine risk of falling. The Fall-Efficacy Scale International was used to examine the fear of falling. The community-based exercise program involved thirty-five participants, the average age was 67.54 years (SD = 3.81) and 71% were female. At-tendance rates ranged from 76% to 100% on average. There was a significant trend toward a clinically important improvement in the timed-up and go test (t = 4.66; p < .001; d = 0.20), berg balance scale (t = -11.20; p < .001; d = 1.47) and fall-efficacy scale international (t = 5.81; p < .001; d = 0.88). This study has provided preliminary evidence that an 8-month community-based low-cost exercise program may be effective in improving agility, balance, and decreasing fear of falling in older people.

Physical Fitness Variables, General Health, Dementia and Quality of Life in Individuals with Intellectual and Developmental Disabilities: A Cross-Sectional Study.

The average life expectancy of individuals with intellectual and developmental disabilities (IDDs) is increasing. However, living more years does not mean living better, leading to the need for research on comorbidities associated with the aging process. Associated with this process are the physical characteristics most prevalent in an individual with IDD: low levels of all physical capacities, the accumulation of central fat, hyperglycemia, dyslipidemia, and hypertension, variables considered to be some of the main risk factors of the onset of metabolic and cardiovascular diseases, and variables that can negatively impact quality of life (QoL). Therefore, the aim of this study is to evaluate a sample of 21 institutionalized adults with IDD (42.81 ± 10.99 years old) in terms of their anthropometric characteristics, body composition, general health status, functional capacity, neuromuscular capacity, and dementia/cognitive function, and the possible associations with QoL. All assessments were performed in the laboratory of the Faculty of Sport Sciences and Physical Education-University of Coimbra. Participants, in the present study, have low levels of physical fitness and high metabolic and cardiovascular markets, which need to be improved. On the other hand, functional and neuromuscular ability seems to be associated with QoL (p ≤ 0.05). This study highlights the role of primary and secondary care providers in diagnosis, prevention, and supporting individuals with IDDs to promote QoL.

Motivation among Teenage Football Players: A Longitudinal Investigation throughout a Competitive Season.

The present study aimed to investigate the dynamic changes in behavioral regulations among teenage football players throughout a competitive season, with three measurement points (T1, T2, and T3). The total sample size for the study comprised 108 participants (78 male; 30 female). The participants' mean age was 14.31 (SD = 1.48). A MANOVA repeated measures analysis was performed within the group for all six behavioral regulations based on self-determination theory. The results of the study revealed noteworthy patterns in the behavioral regulations and intrinsic motivation scores over the competitive season. Identified regulation demonstrated a significant increase from T1 to T3 (p < 0.01, η2p = 0.13). Intrinsic motivation displayed a significant decrease over the same period from T1 to T3 (p < 0.01, η2p = 0.12). On the other hand, amotivation, external regulation, introjected regulation, and integrated regulation did not show significant changes between the three time points. The findings have practical implications for coaches and sports practitioners, as they highlight the need to create a supportive and autonomy-promoting environment to sustain athletes' intrinsic motivation throughout a competitive season. Also, recognizing the increase in identified regulation can inform strategies that align team goals and training sessions with players' individual values, thereby enhancing their commitment and dedication to the team's success.

Analysis of Exercise Intensity Preferences, Tolerance, Competence, and Their Implications for Behavioral Intentions in Fitness Settings.

This study aims to comprehensively investigate the interrelationships among exercise intensity preference, tolerance, competence satisfaction, competence frustration, and exercise intentions within the fitness domain. The research involved 114 participants aged 18 to 59 years (M = 33.23; SD = 10.542), with an average height of 166.02 cm (SD = 15.856) and weight of 68.02 kg (SD = 13.658). The path analysis revealed positive correlations among constructs, except for the link between exercise intensity tolerance and competence satisfaction. Notably, exercise intensity preference positively related to competence satisfaction (ß = 0.20, CI90% = 0.12, 0.40), while both preference and tolerance were negatively linked to competence frustration (preference: ß = -0.27, CI90% = -0.44, 0.03; tolerance: ß = -0.17, CI90% = -0.03, 0.24). Competence satisfaction (ß = 0.37, CI90% = 0.13, 0.34) and competence frustration (ß = -0.29, CI90% = -0.48, -0.09) significantly influenced exercise intentions. An indirect effect existed between exercise intensity preference and intentions (ß = 0.11, CI90% = 0.03, 0.21), contrasting with the lack of such effect for intensity tolerance (ß = 0.05, CI90% = -0.01, 0.14). Intentions explained 16% of the variance. In conclusion, this study underscores the intricate connections between exercise intensity traits and intentions, shedding light on factors influencing individuals' exercise persistence.

Effects of exercise on body mass index and waist circumference of individuals with intellectual and developmental disabilities: a systematic review with meta-analysis.

Introduction/Methods: This systematic review with meta-analysis aims to assess the magnitude of the effects of physical exercise programs on body mass index (BMI) and waist circumference (WC) of individuals with Intellectual and Developmental Disabilities (IDD), metabolic and cardiovascular health markers. Results: Considering the eligibility criteria, a final sample of nine articles was obtained. For BMI, the Z-value obtained to test the null hypothesis (difference between means is zero), showed a Z = -2.176 and p = 0.03. The highest magnitude of the effect was from the intervention with combined training (difference in means: -0.399), with a value of Z = -1.815 and p = 0.07. For WC, the Z-value is zero, showing a Z = -3.306 and p = 0.001. The highest magnitude of the effect was from the intervention with continuous cardiorespiratory training of -0.786, with a value of Z = -2.793 and p = 0.005. Discussion: Physical exercise prevents increases in BMI and WC in individuals with IDD. Aerobic training seems to be more effective in promoting WC and combined training in BMI. Systematic Review Registration: [PROSPERO], identifier [CRD42021255316].

Prescription and Effects of Cardiorespiratory Training in Individuals with Intellectual Disability: A Systematic Review.

This study aims to systematize effects of cardiorespiratory training (CT) programs in individuals with intellectual disability (ID) and identifying the fundamental and structuring aspects for the prescription of CT. This systematic review was carried out through four databases (Pubmed, Web of Science, Scopus, and SPORTDiscus), considering data from the period between 2013 and 2022. From 257 studies, 12 studies were included in this systematic review. Three studies used interval CT, while seven used continuous CT. Seven were carried out in the population with Down syndrome, while only three were carried out with participants with ID. The CT programs had the following characteristics: duration of 8 to 12 weeks, weekly frequency of three sessions, for 20 to 60 min, the intensity of 50% to 80% of maximal heart rate or 70% to 80% of peak oxygen consumption, using an ergometer cycle or an outdoor walking. The studies reported improvements in cardiorespiratory function, lipid, hemodynamic and metabolic profile, body composition, and neuromuscular and cognitive capacity. This review presents characteristics and recommendations that technicians can follow when structuring, prescribing, and implementing CT programs to individuals with ID.

Using Psychometric Testing Procedures for Scale Validity, Reliability, and Invariance Analysis: The PRETIE-Q Portuguese Version.

This study investigated the psychometric nature of preference for and tolerance of exercise intensity in physical activity. It initially re-examined the Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) among Portuguese exercisers, looking at its applicability to different exercise activities and exercise experiences. Then, to investigate the applicability of the measure in different groups, its invariance was examined. The sample consisted of 1117 participants (528 male, 589 female) aged 18-81 years old (Mage = 36.81, SD = 11.89). All participants reported at baseline that they were exercising, on average, 3.93 days (SD = 1.36) per week. The exploratory structural equation modeling (ESEM) displayed the best fit. The ESEM did show invariance when tested for multigroup analysis. The conclusion of this research is that the ESEM demonstrated the best fit, displaying invariance in multigroup analysis. Furthermore, when assessing preference and tolerance in various exercise modalities, the PRETIE-Q should be primarily used as a multidimensional instrument due to the differential recognition of preference and tolerance in seemingly similar physical activity circumstances, highlighting the importance of employing context-verified measures to evaluate exercise-intensity preference and tolerance based on sample characteristics or real-time context.

Effects of a 24-week exercise program on anthropometric, body composition, metabolic status, cardiovascular response, and neuromuscular capacity, in individuals with intellectual and developmental disabilities.

Introduction: The prevalence of overweight and obesity has increased in the last decades, including in people with Intellectual and Developmental Disabilities (IDD). This is even more concerning when it is globally accepted that a low physical condition contributes to the deterioration of functionality and increases the risk of developing chronic diseases during life, with effective implications for health and well-being. The aim of the present study is to investigate the effects of two physical exercise intervention programs on institutionalized individuals with IDD. Methods: Twenty-one adults with IDD (43.04 ± 11.18 years) were split by convenience into three groups: i) an indoor training group (IG; N = 7; 24-week machine-based gym intervention), ii) an outdoor training group (OG; N = 7; 24-week outdoor intervention with low-content materials), and iii) a control group (CG; N = 7). Assessed outcomes included indicators of health and neuromuscular capacity. The ShapiroWilk (n < 50) and Levene tests were used to verify data normality and homoscedasticity. A Kruskal-Walli test was performed to understand if there were differences between the groups. For comparison purposes and to assess hypothetical differences between groups, the Wilcoxon signed-rank test and the Friedman test were used. The respective effect size was calculated, and the significance level was defined at 0.05. Results/Discussion: There was a difference in fat mass in OG (initial ≠ intermediate; Bonferroni corrected: t = 2.405; p = 0.048; W = 0.08 and initial ≠ final moments; Bonferroni corrected: t = 2.405; p = 0.048; W = 0.08). Indoor intervention programs seem to be more effective than outdoor intervention programs for reducing heart rate rest (t = -2.912; p = 0.011; W = -0.104) when compared with CG. Conclusion: A low-cost outdoor intervention in contact with nature appears to be more effective for fat mass reduction. The results for heart rate variability are not clear and robust. Finally, an indoor intervention using weight-training machines appears to be a good method to promote neuromuscular capacity.
