Effects of Functional Training by High Intensity Intervals in Older Adults With Mild Cognitive Impairment.

Effects of a High Intensity Interval Functional Training Program on the Cognitive and Functional Capabilities of Older Adults With Mild Cognitive Impairment.

To analyze the effects of a high intensity interval functional training program (HIFT), in the cognitive and functional capacities of Colombian older adults with mild cognitive impairment.

Study Overview

• Status: Completed
• Conditions: Quality of Life; Aging
• Intervention / Treatment: Other: HIFT Group

Detailed Description

This is a randomized clinical trial of single-blind with 2 arms (Control group and experimental group), in which a pre-treatment-postest design has been used.

The study will define two groups:

A control group (CG) that will not be submitted to treatment, which will be evaluated in the pre and post phase of the study. Participants assigned to this group will receive general advice on the positive effects of regular physical activity and will be given a guide to recommendations for promoting physical activity.

An experimental group (GE) that after an initial evaluation will undergo a physical training program based on high intensity interval functional training exercises.

Once the intervention is finished, it will be submitted to a final evaluation to see if there is a difference or not with the results obtained at the beginning.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Short Form-36 Health Survey (SF-36)	Used extensively for assessing health-related quality of life. The results are values between 0 and 100. Optimal health is represented by scores of 100 and very poor health would equal 0.	Up to twelve weeks
Mini-Mental State Examination (MMSE)	The most widely used cognitive screening test to assess suspected symptoms consistent with cognitive impairment or dementia. Written test with a maximum score of 30. The cut-off point established for the MMSE defines "normal" cognitive function is generally set at 24, lower scores indicate more serious cognitive problems.	Up to twelve weeks
The Yesavage Geriatric Depression Scale	Questionnaire used to screen for depression in older people. Scores from 00 to 05 indicate Normal screening, 06 to 10 Moderate Depression screening, and 11 to 15 Severe Depression screening.	Up to twelve weeks
PSQI (Pittsburgh Sleep Quality Index)	A simple and valid assessment of both sleep quality and disturbance that might affect. They consist of 10 questions divided into four subscales: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep discomfort, medication use and daytime dysfunctions, adding up to a total score. The higher value represents a worse result. Higher scores indicate poorer sleep.	Up to twelve weeks
Tinetti scale	It is used to determine early the risk of falling in an elderly person during the year following its application. The result of both sections will be added, so that a score of less than 19 points will imply a high risk of falls, a score of 19 to 24 will reflect medium risk of falls and a score of 25 to 28 will indicate low risk of falls.	Up to twelve weeks
Frailty phenotype	Five original characteristics are evaluated: involuntary weight loss, self-reported exhaustion, slow gait speed, weakness, and low physical activity.	Up to twelve weeks
The 8 foot up & go test	Assesses agility and dynamic balance.	Up to twelve weeks
MoCA (Montreal Cognitive Assessment)	Instrument that examines the skills of attention, concentration, executive functions, memory, language, visuoconstructive abilities, calculation and orientation and the maximum score is 30.	Up to twelve weeks.
TMT (Trail Making Test)	It is used to assess executive function. It measures timed motor and visual tasks, and is divided into two tests: Part A (TMTA), which assesses speed and psychomotor attention and requires connecting consecutively numbered circles; and Part B (TMTB), which tests executive function and requires connecting alternating circles of numbers and letters. Longer completion times indicate poor performance.	Up to twelve weeks.
Isaacs test	Instrument used to assess verbal fluency. Participants have 60 seconds to generate as many words as possible within a given semantic category (animals, colors, fruits, and cities). The maximum score is 40 points (with a maximum of 10 per category). The higher the score, the better the level of verbal fluency.Instrument used to assess verbal fluency. Participants have 60 seconds to generate as many words as possible within a given semantic category (animals, colors, fruits, and cities). The maximum score is 40 points (with a maximum of 10 per category). The higher the score, the better the level of verbal fluency.	Up to twelve weeks.
SFT (Senior Fitness Test)	Instrument used to assess functional abilities. It consists of the following tests: muscle strength (upper and lower limbs), aerobic endurance, flexibility (upper and lower limbs) and agility, 6-minute walk test, Sit-to-foot test using a chair (measures flexibility of the lower body, Try to clasp hands behind your back, Try to get up, walk 8 feet and sit back.	Up to twelve weeks.
The Lawton & Brody scale	Evaluates independence and functionality in instrumental activities of daily life) such as shopping, cooking, cleaning, washing, finances, medication, transportation and use of the telephone; and considers instrumental disability the inability to perform one or more activities. Each area is scored according to the description that best corresponds to the subject. Therefore, each area scores a maximum of 1 point and a minimum of 0 points. The maximum dependence would be marked by obtaining 0 points, while a sum of 8 points would express total independence. In a conventional way, the following classification can be assumed: Grades A-B or 0 - 1 points = absence of disability or mild disability. Grades C-D or 2 - 3 points = moderate disability. Grades E-G or 4 - 6 points = severe disability.	Up to twelve weeks
KATZ INDEX	Is a widely used tool to assess the level of independency in older adults. It is scored considering the items grouped to obtain degrees A, B, C, etc., of independence. It is observed that 0 points are equal to grade A, 1 point to grade B, 2 points to grade C, 3 points to grade D, and so on. In a conventional way, the following classification can be assumed: Grades A-B or 0 - 1 points = absence of disability or mild disability. Grades C-D or 2 - 3 points = moderate disability. Grades E-G or 4 - 6 points = severe disability.	Up to twelve weeks
Chair sit and reach test	To test low back and hamstring flexibility.	Up to twelve weeks
Back scratch test	To measure general shoulder range of motion.	Up to twelve weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
D2 test	Time-limited test to measure concentration. The test measures the processing speed, the following of instructions and the goodness of the execution in a task of discrimination of similar visual stimuli and that, therefore, allow the estimation of attention and concentration.	Up to twelve weeks.
DSST (The Digit Symbol Substitution Test)	Cognitive test to assess processing speed presented on a single sheet of paper that requires a subject to match symbols with numbers according to a key located at the top of the page. The subject copies the symbol into spaces below a row of numbers. The number of correct symbols within the allowed time, usually 90-120 seconds, constitutes the score.	Up to twelve weeks.
Mindful Attention Awareness Scale (MAAS)	It evaluates, in a global way, the dispositional capacity of an individual to be attentive and aware of the experience of the present moment in everyday life. The scale is a 15-item univariate self-report with a view of the mindfulness construct centered on the attention / consciousness variable.	Up to twelve weeks.
Handgrip Strength	Dynamometer will be employed to assess hand grip stregth.	Up to twelve weeks.
BMI (Body Mass Index)	Is calculated from the formula, Weight (kg) / Height2 (m2), whose unit is kg/m2. It is a rough indicator of total body fat	Up to twelve weeks.
Waist circumference	Is used to assess central fat distribution and degree of abdominal obesity	Up to twelve weeks.
Waist-to-hip ratio	Is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement	Up to twelve weeks.
