Brief Summary

This study compared the effects of IDT and ADT on cognitive function, physical performance, instrumental activities of daily living (IADL), and quality of life in community-dwelling older adults.

Conditions

• Intervention Model: PARALLEL
• Primary Study Purpose: SUPPORTIVE_CARE
• Blinding Strategy: SINGLE

Study Groups

The motor training component

The motor training component included stretching, aerobic exercise, strength training, and balance exercises. Exercise intensity was gradually increased to a moderate level (50-70% of participants' maximum heart rate) using low-impact modalities to minimize injury risk and was adjusted according to individual physical condition throughout the intervention. Warm-up and cool-down periods involved whole-body muscle stretching. Aerobic exercises consisted of walking, marching in place, high knee lifts, kicking motions, leg curls, touchdown steps, and box steps, combining upper and lower limb movements to produce rhythmic and repetitive patterns. Strength training comprised squats, lunges, chair sit-to-stands, weightlifting using water-filled bottles, farmer's walks, and elastic band exercises targeting both upper and lower limbs. Balance exercises included single-leg stands, heel-to-toe walking, ball kicking, and cross-stepping.

Group Type: EXPERIMENTAL

the additional dual-task training group (ADT)

Intervention Type: BEHAVIORAL

the cognitive task was performed concurrently but independently from the motor task, functioning as a distractor rather than a necessary prerequisite for task completion. Examples included performing lower limb strength exercises while solving arithmetic problems or reciting memorized items while stepping.

the incorporated dual-task training group (IDT)

Intervention Type: BEHAVIORAL

the cognitive task was integrated within the motor task and was essential for successful completion of the combined motor-cognitive activity. Examples included memorizing and executing movement sequences akin to dancing or completing ladder stepping patterns in a predetermined order.

The cognitive training

The cognitive training targeted domains such as attention, language, memory, calculation, and processing speed. Each session incorporated one or more cognitive domains. Attention tasks involved responding to visual or auditory cues, spotting differences in quantity, size, color, direction, or shape, and identifying specific objects within cluttered environments. Language tasks included naming fruits, animals, and vegetables, playing word solitaire, engaging in word association, constructing sentences, spelling, reading, and picture-based storytelling. Calculation tasks required solving arithmetic problems or calculating shopping list costs. Processing speed activities involved timely responses to questions, such as number comparisons. Memory tasks focused on recalling numbers, symbols, words, or daily items after presentation, as well as remembering spatial locations, shopping lists, or informational content from brochures and images.
