Purpose

To analyze the effects of a 6-week multidomain walking training program (MWTP) with mHealth technology on health status, cognitive performance, and physical function in older adults.

Design

Controlled longitudinal intervention study with pre- and post-intervention assessments.

Setting

Community-based, autonomous outdoor environments.

Sample

Forty-nine sedentary older adults (mean age 69.9 ± 3.7 years) allocated to an experimental (n = 21) or control group (n = 28).

Intervention

The experimental group followed a 6-week mHealth-supported MWTP combining endurance, strength, and dual-task cognitive exercises, with progressive intensity and volume. The control group maintained usual routines.

Measures

Physical fitness (lower limb strength, walking speed, cardiorespiratory capacity), cognitive function (executive function), and health variables (anthropometric and psychosocial) were assessed using standardized tests.

Analysis

Data were analyzed using SPSS v.19.0. Descriptive statistics, normality and homogeneity tests, and appropriate parametric (2 × 2 repeated-measures ANOVA, ANCOVA) and non-parametric (Mann–Whitney U, Wilcoxon) tests were applied (α < 0.05).

Results

The experimental group showed significant improvements in lower limb strength, walking speed, and cardiorespiratory capacity. Executive function was preserved in the experimental group but declined in the control group. No significant changes were found in anthropometric or psychosocial measures.

Conclusion

The MWTP enhances physical fitness and preserves executive function in older adults. Its autonomous, mHealth-supported format offers a scalable and cost-effective strategy for promoting healthy aging.
