This study aims to evaluate the effects of a combined marching exercise with cognitive training program on physical performance, cognitive function, and autonomic cardiovascular responses in older adults with type 2 diabetes mellitus. Participants will be randomly assigned to either an intervention group receiving marching exercise with cognitive tasks or a control group receiving usual care. Outcomes will be assessed before and after the intervention period. The findings are expected to provide evidence for a feasible and safe exercise strategy to improve physical and cardiovascular health in older adults with type 2 diabetes.
Type 2 diabetes mellitus is highly prevalent among older adults and is associated with declines in physical function, cognitive performance, and autonomic cardiovascular regulation. Reduced physical activity and impaired autonomic nervous system function may increase the risk of functional limitation, falls, and cardiovascular complications in this population. Exercise interventions that simultaneously challenge physical and cognitive domains may provide additional benefits beyond conventional exercise alone.
This single-blind, randomized controlled trial investigates the effects of a marching exercise program combined with cognitive training on physical function, cognitive performance, and autonomic cardiovascular responses in older adults with type 2 diabetes mellitus. Eligible participants aged 60 years and older will be recruited from the community and randomly assigned to either an intervention group or a control group.
The intervention group will participate in a structured marching exercise program integrated with cognitive tasks, conducted three times per week for eight weeks. The control group will receive usual care and standard health advice. Physical performance outcomes will include measures of mobility, balance, and cardiorespiratory fitness. Cognitive function will be assessed using standardized cognitive tasks. Autonomic cardiovascular responses will be evaluated using heart rate variability parameters.
Outcome measures will be assessed at baseline and after completion of the intervention. This study aims to provide clinical evidence supporting a practical and community-based dual-task exercise approach for improving physical, cognitive, and autonomic cardiovascular health in older adults with type 2 diabetes mellitus.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Modified Marching Exercise combined with Cognitive Training | Experimental | Participants in this group perform a Modified Marching Exercise combined with dual-task cognitive training. The exercise consists of rhythmic marching movements while simultaneously performing cognitive tasks such as backward counting and reciting months in reverse order. Each session lasts approximately 30 minutes and is conducted according to the assigned intervention protocol. |
|
| Modified Marching Exercise | Experimental | Participants in this group perform the Modified Marching Exercise alone without concurrent cognitive tasks. The exercise involves rhythmic marching movements adapted to individual functional ability. Each session lasts approximately 30 minutes and follows the same frequency and duration as the experimental intervention. |
|
| Control group | No Intervention | Participants in the control group receive health education and educational pamphlets focused on fall prevention. They continue their usual daily activities without participation in a structured exercise program during the study period. |

| Modified Marching Exercise combined with cognitive training group | Other | The exercise program consists of a Modified Marching Exercise that emphasizes lifting the knees to touch a designated rope during each step. A metronome is used to maintain a rhythmic pace of 60-80 beats per minute throughout the training. In addition, participants perform concurrent cognitive dual-task training designed to stimulate executive function. The cognitive tasks include countdown calculations, backward sequencing of months and weekdays, and a Stroop interference task. Each session lasts approximately 30-40 minutes and includes a 5-minute warm-up and a 5-minute cool-down. Exercise intensity is individually adjusted according to the participant's fitness level. The program is conducted three times per week for 6 consecutive weeks, for a total of 18 sessions. This combined cognitive-motor training is designed to integrate physical and cognitive demands in order to improve movement efficiency, balance control, and responses to daily functional stimuli. |
| Measure | Description | Time Frame |
|---|---|---|
| Heart rate variability (HRV) | Heart Rate Variability (HRV) Assessment HRV is assessed using the SA-3000P device to evaluate Autonomic Nervous System (ANS) function, stress resistance, and arterial elasticity. The procedure involves a 3-minute measurement using a finger probe while the subject sits quietly. The device automatically analyzes the data to provide time-domain indices (such as SDNN), which are used to assess cardiac function and prognosis. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Handgrip strength test | Handgrip Strength Testing This test assesses hand and forearm muscle strength using a hand grip dynamometer. The subject stands upright with the dominant arm extended alongside the body (abducted approx. 15 degrees), elbow straight, and palm facing down. Upon the "start" signal, the subject squeezes the device as hard as possible. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Five times sit-to-stand test (FTSST) | Leg Muscle Strength Test (FTSST) The Five Times Sit to Stand Test measures leg strength using a standard armless chair. The subject performs five consecutive stand-to-sit cycles as quickly and safely as possible from a seated position (hips ~90°). Time is recorded from the start signal until the final return to sitting. The average of three trials is calculated (Kaewjoho et al. 2020). | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Timed Up and Go Test (TUGT) | Assessing Balance Ability (TUGT) The Timed Up and Go Test (TUGT) evaluates dynamic balance and fall risk. The subject starts seated, stands up on signal, walks 3 meters around a cone, and returns to sit as quickly and safely as possible. The average time of three trials is recorded. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |

| Static Balance Single-leg stance test (SLST) |
Static Balance (SLST) The Single-leg stance test assesses static balance. The subject stands on their dominant leg with the other knee bent at 90° and arms crossed over the chest. Timing measures how long the position is maintained without error (e.g., foot touching the ground, moving arms). The average time of three trials is calculated in seconds. |
| Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| 6-minute walk test | 6-Minute Walk Test (6MWT) This test assesses cardiopulmonary endurance. The subject walks as fast as possible (without running) for 6 minutes on a rectangular course (45m perimeter). Resting is allowed, but the timer continues. The total distance covered is measured to calculate VO2max. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Motor-Cognitive Dual-Task Test: | Motor-Cognitive Dual-Task Test (S-TMT) The Stepping Trail Making Test assesses dual-task motor-cognitive function. The subject steps on squares numbered 1 to 16 in order as quickly and accurately as possible. The time taken to complete the sequence, including any error corrections, is recorded. The test is performed only once. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Motor-Cognitive Dual-Task Test | Motor-Cognitive Dual-Task Test (F8WT) The Figure-of-8 Walk Test assesses dynamic balance and turning ability. The subject walks a figure-of-8 pattern around two cones spaced 1.5 meters apart. Time is recorded for one complete lap. In the Dual-Task variation (F8WT-MC), the subject performs the walk while holding a cup of water in their dominant hand. | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
| Montreal Cognitive Assessment (MoCA) | Assessment of Cognitive Impairment (MoCA) The MoCA test is a screening tool for cognitive impairment covering various brain functions (e.g., memory, attention). It involves a 10-15 minute interview with a maximum score of 30. A score below 26 indicates mild cognitive impairment (MCI). | Baseline, immediately after 6 weeks of intervention, and 1-month follow-up |
