About this study

Official title: Efficacy of a High-Intensity Interval Exercise Program Versus a Dual-Task Training Program in People With Alzheimer's: A Randomized Clinical Trial

Alzheimer's disease (AD) is a the most common type of dementia. It is a progressive disease that affects different areas of human behavior at the cognitive, social, physical and metabolic levels. The benefits of a High-Intensity Interval Exercise Program (HIIT) has been proven not only in healthy older adults, but also in different pathologies, such as cerebrovascular and cardiometabolic diseases. However, there are no studies to date that examine the impact of HIIT in people with AD. The aim of this study was to ascertain the effectiveness of a HIIT program versus a cognitive and motor dual task balance program on parameters related to functional capacity and cognitive function in people with AD.

Read the detailed description

Alzheimer's disease (AD) is a the most common type of dementia. It is a progressive disease that affects different areas of human behavior at the cognitive, social, physical and metabolic levels.

The benefits of interventions such as dual-task training (TD) have been the focus of studies in recent years in AD. Current evidence shows that DT training leads to improvements in parameters related to frontal cognitive function, such as: planning, organization, strategy creation, abstraction, motor sequencing, working memory, thinking flexibility, visual search, sequencing, sustained attention and working memory. DT training has been also shown to improve variables related to gait ability and balance, such as step length and gait speed, postural control and specific functional tasks under challenging conditions of double task. However, AD is also associated with reduced cardiovascular fitness and decreased muscle strength, thus leading to a loss of independence in activities of daily living and poor quality of life.

A promising intervention to address these issues is high-intensity interval exercise (HIIT), defined as brief intermittent bursts of vigorous activity interspersed with periods of rest or low-intensity exercise. Indeed, it has been reported that HIIT generates greater benefits in cardiorespiratory capacity and greater metabolic adaptations than continuous exercise of moderate intensity in healthy older adults. HIIT interventions have resulted in benefits on variables related to functional capacity, such as improved gait speed, increased muscle mass and strength. Furthermore, HIIT has been shown to improve variables related to cognitive function, such as attention, perception and memory abilities.

However, there are no studies to date that examine the impact of HIIT in people with AD. The aim of this study was to ascertain the effectiveness of a HIIT program versus a cognitive and motor dual task balance program on parameters related to functional capacity and cognitive function in people with AD.

Therefore, a randomized clinical trial will be carried out, in which three groups of twenty people in each group will participate, with different interventions:

  • Experimental group 1: HIIT (HIIT)
  • Experimental group 2: Dual task training (DT)
  • Control group: No intervention (CG) Participants will be evaluated in three moments, at baseline (T1), post-intervention (T2) and at 2 month-follow-up (T3).

Data analysis will be performed with SPSS statistic program (v26). Normality and homoscedasticity will be analyzed by Shapiro-Wilk t-test and Levene test, respectively. For comparation between groups Bonferroni will be used. If any confusion factor that not meet requirements to be analysed like a covariable exist, ANCOVA will be used. When p<0.0.5 statistical significant differences will be assumed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HIIT interventionOther

    Patients will perform a muscle strength training circuit interspersed with resistance training circuit. The strength training circuit will consist of 10 strength exercises and resistance training circuit will consist of walking, jogging and running exercises. Each exercise will be performed for one minute, trying to reach maximum intensities adapted to each individual's condition.

  • Dual task interventionOther

    Dual task training will consist of the progressive and specific assignment of primary motor tasks and secondary motor or cognitive tasks focused on: i) Primary tasks: static, dynamic balance and gait exercises; ii) Secondary tasks (motor or cognitive): verbal fluency, mathematical calculation, memory, visual-spatial planning, auditory discrimination, fine motor task, motor transport task.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline cardiorespiratory fitness

    6 minutes walking test" (6MWT): distance (m)

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  2. Change from baseline balance ability

    Star Excursion Balance Test: maximal distance in all directions (cm), 3 times

    Measured: At baseline, post-intervention and at 2 month-follow-up

Secondary outcomes (8)
  1. Change from baseline lower limb isometric strength

    Lafyette dynamometer: quadriceps, hamstrings, gastrocnemius,tibialis anterior

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  2. Change from baseline lower limb power

    30 Second Sit to Stand Test: number of times the patient comes to a full standing position in 30 seconds

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  3. Change from baseline Risk of Falling

    Timed up and go: time (in seconds) that a person takes to rise from a chair, walk three meters, turn around 180 degrees, walk back to the chair, and sit down while turning 180 degrees. An older adult who takes ≥12 seconds to complete the TUG is at risk for falling

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  4. Fall frequency

    Fall diary. The individual is asked to write down how many times he/she falls during a period.

    Measured: Daily for 12 weeks (the length of the intervention)

  5. Change from baseline Fear of falling

    Falls Eficacy Scale International. It is a 16 item questionnaire, useful to the researchers and clinicians interested in fear of falling, with a score ranging from minimum 16 (no concern about falling) to maximum 64 (severe concern about falling)

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  6. Change from baseline Cognitive status

    Mini-Mental State Examination: The Mini-mental state examination is scored on a scale of 0-30 with scores > 24 interpreted as normal cognitive status.

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  7. Change from baseline Executive function status

    Stroop test: Three scores, as well as an interference score, are generated using the number of items completed on each page, with higher scores reflecting better performance and less interference on reading ability.

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up

  8. Change from baseline depression levels

    Geriatric Depression Scale (15-item scale): This scale is scored form 0 to 15. A score higher than 5 points suggests depression.

    Measured: At baseline, immediately after the intervention and at 2 month-follow-up
