Comparison of the Cognitive, Dual-task and Physical Effects of 6 Programs With Older Adults

All subjects must give their informed consent for inclusion before they participate in the study. The study will be conducted in accordance with the Declaration of Helsinki, and the protocol has been approved by the University Paris Saclay Ethics Committee of Research (N°462) who stated that a Protection of Persons Committee was not necessary. The sample size calculation was performed using G. Power. The investigators calculated a sample size sufficient to detect small effect sizes (η2 = .04). Therefore, f = 0.20, α = 0.05, p = 0.95, power = 0.95, were chosen to favor clinically significant effect sizes. To test the main hypotheses of the present study, 133 participants are required. To compensate for possible dropouts, 35 more participants will be included. The 7 groups will be composed of 24 participants each, for a total of 168 participants. The training interventions will be carried out in different places and at different times: * Montreuil for I2WE and 2CMA (February to May 2023) * Créteil for EXER (September to December 2023) * Paris for BIKE and VG-BIKE (February to May 2024) * Orsay for VG (September to December 2023). Pre- and post-tests will be carried out before and after the training period to evaluate the cognitive, DT, and physical benefits of each program, and retention tests 3 months after the end of the program. Statistical analysis plan: Data will be analyzed with JASP software. The statistical analysis will allow us to determine the effects of the 7 different groups on the cognitive, DT, and physical functions. The analysis will include only subjects who completed all the pre- and post-tests. Data from the pre-tests, post-tests, and retention tests will be presented using descriptive statistics (mean, standard deviation) to describe the participants' characteristics and performances on assessments. Before performing the inferential statistical tests, all relevant hypotheses will be tested, and if they are met, statistical analysis will be conducted. For primary and secondary measures, repeated ANOVA will be used to test the interaction between pre-test, post-test, retention test x training groups. If a significant interaction is found, a Bonferroni post-hoc test will be performed. Effects sizes will be calculated to study the power of the results.
