Background and study aims
Scientific evidence supports that physical activity and adequate nutrition can enhance the quality of life of individuals with intellectual disabilities (ID). The aim of this study is to assess the effects of a sports program based on judo, together with actions aimed at improving nutritional habits, for adolescents with intellectual disabilities.
Who can participate?
Adolescents between 14 and 22 years old with a mild to moderate degree of intellectual disability
What does the study involve?
One group will be exclusively made up of participants with ID, while another will be integrated into the regular classes of a judo club together with participants without ID. The control group will consist of adolescents with ID who do not participate in extracurricular sports activities.
The judo sessions take place in a large and well-ventilated space with a 120 m² tatami made of high-density foam. Each participant wears a judogi, which includes a jacket, pants and belt. Sessions last 60 minutes and are led by two black belt teachers, supported by four volunteer instructors. The sessions are divided into three parts: warm-up, main judo exercise and cool down. They include general movements and landing techniques, simplified judo-specific movements and sets, ground control and throwing techniques, and repetitions of basic technical movements. The instruction method follows a principle of gradual progression, allowing participants to progress at their own pace through guided imitation and modeling of techniques.
At the same time, initiatives to improve nutritional habits will be carried out jointly in the family environment and during judo sessions. At the end of each judo session, it will be established that each participant consumes fresh fruit, requiring the collaboration of families to facilitate this action. Subsequently, in the family environment, each occasion in which fruit or vegetables are consumed must be documented through photographs, which will be uploaded to an exclusive mobile application for participants, family members, researchers and teachers. Gamified rewards will be established to encourage the consumption of healthy foods. Finally, the results will be compared in the period before and after the intervention.
What are the possible benefits and risks of participating?
The practice of judo is expected to improve quality of life, physical condition and nutritional habits. There is no risk of negative effects.

| Scientific title | Longitudinal study of the effects of a sports program based on judo for adolescents with intellectual disabilities |
| Study acronym | JIDP |
| Study objectives | Based on the formulated objectives, the following hypotheses are proposed, taking into account those situations in which statistical significance can be obtained (P<0.05): The group of adolescents with ID who participate in the judo program will present better results in the indicators of physical condition, nutritional habits, social interaction and quality of life. A secondary hypothesis that is formulated is based on the fact that the group that participates in regular judo sessions with adolescents without ID will present better results than the group that exclusively attends the sessions with subjects with ID in the evaluated indicators. |
| Ethics approval(s) |
Approved 05/02/2024, Research Ethics Committee of the Ramon Llull University (Claravall Street, 1, 3, District de Sarrià-Sant Gervasi, Barcelona, 08022, Spain; +34 (0)936 02 22 00; rbabington@rectorat.url.edu), ref: CER URL_2023_2024_011 |
| Health condition(s) or problem(s) studied | Adolescents with intellectual disabilities |
| Intervention | Participation in a judo-based sports program for 2 days per week during a school year The design of the study is a simple crossover, quasi-experimental with random groups and non-probabilistic convenience sampling. The independent variable (group) will have three levels: a) a group with isolated ID, b) an inclusive group of subjects with ID plus participants without ID, and c) a control group composed of subjects who do not practice any extracurricular physical activity and come from special education centers and schools. In order to comply with ethical recommendations, two intervention periods will be established so that participants who commit according to their availability can participate in an intervention period, attending regular judo sessions with adolescents without disabilities and another intervention period attending judo sessions exclusively with subjects with intellectual disabilities. The judo sessions take place in a large and well-ventilated space with a 120 m² tatami made of high-density foam. Each participant wears a judogi, which includes a jacket, pants and belt. Sessions last 60 minutes and are led by two black belt teachers, supported by four volunteer instructors. The sessions are divided into three parts: warm-up, main judo exercise and cool down. They include general movements and landing techniques, simplified judo-specific movements and sets, ground control and throwing techniques, and repetitions of basic technical movements. The instruction method follows a principle of gradual progression, allowing participants to progress at their own pace through guided imitation and modeling of techniques. At the same time, initiatives to improve nutritional habits will be carried out jointly in the family environment and during judo sessions. At the end of each judo session, it will be established that each participant consumes fresh fruit, requiring the collaboration of families to facilitate this action. Subsequently, in the family environment, each occasion in which fruit or vegetables are consumed must be documented through photographs, which will be uploaded to an exclusive mobile application for participants, family members, researchers and teachers. Gamified rewards will be established to encourage the consumption of healthy foods. Finally, the results will be compared in the period before and after the intervention. |
| Intervention type | Behavioural |
| Primary outcome measure | 1. Physical fitness evaluated with the ALPHA-FITNESS battery 2. Quality of life in adolescents evaluated with the KIDSLIFE scale 3. Nutritional habits evaluated using the KIDMED questionnaire. An app will be created to monitor and record the consumption of healthy foods, in which they can compare and encourage themselves with the rest of the participants. 4. Satisfaction with the program evaluated using the Physical Activity Enjoyment Scale (PACES) All evaluations will be carried out at the beginning and end of the intervention |
| Secondary outcome measures | A secondary measure that is evaluated is the comparison of the results according to the group, since the participants will be carried out in two modalities: an isolated group (where all participants have ID) and an inclusive group (where the group is made up of adolescents. with and without ID). All evaluations will be carried out at the beginning and end of the intervention. |

| Publication and dissemination plan | The researchers estimate the production of three articles in high-impact JCR journals. This is a volume of publications in line with the trajectory of the members of the requesting research group. Following European recommendations, open-access articles will be prioritized in both Green Open Access (Adapted Physical Activity Quarterly, Journal of Intellectual Disability Research, Research in Developmental Disabilities) Participation in prestigious international conferences: The results obtained in the different stages will also be presented at international conferences of recognized international prestige. The main objective is to participate every year in either the European Congress of Sports Sciences (ECSS) or the American Congress of Sports Medicine (ACSM). At an international level, the impact of the results is guaranteed thanks to the network of collaborating researchers from different countries (United States, Italy, Ireland, Japan). Any positive consequence of this study will be immediately applicable to other research groups. The existing linkage of the research team with other national and international researchers in the field of Adapted Physical Activity guarantees a wide impact. |
| IPD sharing plan | During the first month of the project, a Data Management Plan (PGD) will be carried out that will establish how the data will be managed during the duration of the project and its continuity, however, it will be reviewed and modified if needed throughout the project. of the development and execution of the project. To carry it out, CORA EINA DMP will be used (an adapted version based on the model created by the Center for Digital Curation), a tool that guarantees that data management complies with the FAIR principles (Findable, Accessible, Interoperable and Reusable). The obtaining, processing, conservation, communication and transfer of data will be done in accordance with the provisions of the General Data Protection Regulation of the European Union and Organic Law 3/2018, of December 5, on data protection and guarantees of digital rights all data obtained will be analyzed and used only for the scientific objectives of the study. The primary data will be collected through registration sheets and preserved in the following way: pseudonymized (coded). Pseudonymization is the processing of personal data in such a way that they cannot be attributed to a data subject without the use of additional information. Therefore, the participants will be pseudonymized, leaving the identification codes only in the hands of the PIs and the field research team. The regulations that regulate the processing of personal data give participants the right to access their data, object, correct it, cancel it, limit its processing, restrict or request its deletion. They may also request a copy of it or for it to be sent to a third party (right of portability). The data will be stored in CSV, xlsx or txt formats in a virtual folder at Blanquerna-Ramon Llull University (B-URL), with limited access to researchers. With the aim of offering open access and giving visibility to the data obtained in the project, once completed (approximately 6 months), the main blocks of the study will be deposited, stored, shared, disseminated and preserved in the data publication repository. in open trust with which the URL (CORA Repositori de Dades de Recerca) participates, a specific repository for data from Catalan universities and CERCA centers. These are published in open access, following the FAIR principles and taking into account ethical and legal aspects, if applicable, through data sets (datasets) made up of the file or files of the research data, an identifier, a description of the formats used, descriptive metadata of the data, the readme file and, if necessary, other context documentation. Said metadata will be indexed in Google Dataset Search, DataCite Search, OpenAIRE and Mendeley Data. |
