简要总结
This randomized controlled trial will examine whether the frequency of adapted Argentine tango training affects walking and cognitive function in adults aged 55 to 60 years when the total weekly intervention time is kept the same.
A total of 270 participants will be randomly assigned in equal numbers to one of three groups. The distributed tango group will attend five 36-minute sessions per week. The concentrated tango group will attend two 90-minute sessions per week. The active control group will attend two 90-minute sessions per week consisting of health education and low-intensity stretching. All interventions will continue for 8 weeks.
The adapted Argentine tango program will include low-impact multidirectional stepping, weight shifting, movement initiation and stopping, rhythmic cueing, direction changes, alternating leader-follower roles, and progressive movement-sequence learning. Jumping, rapid continuous turning, large kicks, and other high-risk movements will not be included.
Assessments will be conducted at baseline, Week 4, Week 8, and 2 weeks after the intervention ends. The main outcome will be the change in dual-task walking cost at week 8. Other assessments will examine balance, walking performance, executive function, general cognitive function, lower-limb function, exercise adherence, training intensity, falls, and adverse events.
The study aims to determine whether shorter, more frequent sessions or longer, less frequent sessions provide greater motor-cognitive benefits when the total weekly intervention time is equal.
详细描述
Dance combines aerobic activity, dynamic balance, rhythmic movement, motor-sequence learning, spatial orientation, and cognitive-motor coordination. Adapted Argentine tango may be particularly suitable for improving motor-cognitive function because it requires multidirectional stepping, weight shifting, movement initiation and cessation, direction changes, rhythmic synchronization, and continuous planning of subsequent movements.
Previous dance intervention studies have varied substantially in dance style, training frequency, session duration, exercise intensity, and total training volume. Consequently, it remains unclear whether the distribution of training sessions across the week independently influences motor-cognitive outcomes. This study will compare two adapted Argentine tango schedules while maintaining the same total weekly intervention time.
This will be a single-center, three-arm, parallel randomized controlled trial involving 270 adults aged 55 to 60 years. After eligibility screening, written informed consent, and baseline assessment, participants will be randomly allocated in a 1:1:1 ratio to a distributed tango group, a concentrated tango group, or an active control group. Randomization will be stratified by sex and implemented using variable block sizes. Outcome assessors and statistical analysts will be blinded to group allocation whenever feasible.
Participants in the distributed tango group will complete five 36-minute sessions per week, providing a total weekly intervention time of 180 minutes. Each session will consist of approximately 6 minutes of warm-up, 24 minutes of adapted tango, and 6 minutes of cool-down. Participants in the concentrated tango group will complete two 90-minute sessions per week, also providing 180 minutes per week. Each session will consist of approximately 15 minutes of warm-up, 60 minutes of adapted tango, and 15 minutes of cool-down, with appropriate rest and water breaks. Participants in the active control group will complete two 90-minute sessions per week consisting of general health education, low-intensity joint mobility exercises, stretching, and relaxation activities. The control program will not include systematic tango steps, progressive movement-sequence learning, or cognitively demanding direction-switching tasks.
The adapted Argentine tango intervention will be progressively delivered over 8 weeks. Early sessions will emphasize postural control, weight shifting, forward stepping, and lateral stepping. Subsequent sessions will introduce backward stepping, movement initiation and stopping, rhythm changes, small crossover steps, and controlled 90-degree turns. Later sessions will incorporate alternating leader-follower roles, music- and direction-based cues, progressively longer movement sequences, and low-difficulty dual-task activities. High-risk movements, including jumping, rapid continuous spinning, deep lunges, large kicks, boleos, ganchos, and eyes-closed movement, will be excluded.

- •Willing and able to attend the assigned intervention sessions and complete the scheduled assessments.
- •Able to provide written informed consent.
排除标准
- •Uncontrolled hypertension, unstable angina, recent myocardial infarction or stroke, severe cardiac arrhythmia, or another cardiovascular condition that makes moderate-intensity exercise unsafe.
- •A neurological disorder that substantially affects gait, balance, cognition, or the ability to complete the study procedures.
- •Severe cognitive impairment, psychiatric illness, or communication difficulty that prevents understanding of the study or valid completion of the assessments.
- •A recent fracture, severe musculoskeletal disorder, acute joint injury, severe dizziness, or another condition associated with an unacceptably high risk of falling or exercise-related injury.
- •Current participation in another structured dance, balance, cognitive-motor, or exercise intervention study that may affect the study outcomes.
- •Any other medical or functional condition that, in the judgment of the study investigator or qualified safety assessor, makes participation unsafe or may interfere with completion of the study.
研究组 & 干预措施
Distributed Adapted Argentine Tango
Participants will complete adapted Argentine tango training five times per week for 8 weeks. Each 36-minute session will include approximately 6 minutes of warm-up, 24 minutes of adapted tango, and 6 minutes of cool-down, providing a total intervention time of 180 minutes per week.
干预措施: Distributed Adapted Argentine Tango Training (Behavioral)
Concentrated Adapted Argentine Tango
Participants will complete adapted Argentine tango training twice per week for 8 weeks. Each 90-minute session will include approximately 15 minutes of warm-up, 60 minutes of adapted tango, and 15 minutes of cool-down, with appropriate rest and water breaks, providing a total intervention time of 180 minutes per week.

Active Control
Participants will attend two 90-minute sessions per week for 8 weeks. Sessions will consist of general health education, low-intensity joint mobility exercises, stretching, breathing exercises, and relaxation activities. The program will not include systematic tango steps, progressive movement-sequence learning, or cognitively demanding direction-switching tasks.

结局指标
主要结局
Change From Baseline in Dual-Task Walking Cost at Week 8
时间窗: Baseline and Week 8
Dual-task walking cost will be calculated using walking speed under single-task and dual-task conditions according to the following formula: \[(single-task walking speed - dual-task walking speed) / single-task walking speed\] × 100%. Walking speed will be measured in meters per second. A higher percentage indicates greater dual-task interference and poorer motor-cognitive performance. The primary analysis will compare the change from baseline to Week 8 among the three study groups.
