15 de abril de 2019 actualizado por: Sean Mullen, University of Illinois at Urbana-Champaign

Acute Effects of Aerobic Exercise and Relaxation on Fatigue and Executive Function in Breast Cancer Survivors

The purpose of this acute study is to compare the combined effects of aerobic exercise and relaxation training on fatigue and its related cognitive components, among breast cancer survivors. Participants will complete three sessions over a seven-day period in a laboratory setting.

Descripción general del estudio

Descripción detallada

It is hypothesized that the combination of aerobic exercise and relaxation training could have additive effects on fatigue and related cognitive outcomes. Therefore, this study is designed to test the effects of exercise plus relaxation relative to aerobic exercise alone and relaxation training alone, over the course of three sessions within a seven day period. Participants will complete baseline and post-testing before and after the week of training, as well as pre- and post-testing at each session.

Participants will be randomized to one of three conditions:

  1. Aerobic Exercise Only Condition (AERO) Participants randomized to the AERO condition will engage in three separate 20-minute sessions comprised of a 5-minute, resistance-free warm-up, and 15 minutes of moderate aerobic cycling on a stationary bike (50-70% age-predicted heart rate max). Each AERO session will end with a 20-minute quiet rest period.
  2. Relaxation Only Condition (RELAX) Participants in the RELAX condition will complete three separate 20-minute sessions of relaxation training using a commercial neurofeedback device (headset & smartphone app). Each RELAX session will end with a 20-minute quiet rest period.
  3. Aerobic Exercise and Relaxation Training - Intervention Condition (COMBINED) Participants randomized to the COMBINED condition will complete three separate sessions comprised of 20 minutes of AERO exercise followed by 20 minutes of RELAX training.

All participants, regardless of condition will complete brief questionnaires assessing in-the-moment fatigue and affect, before and after each randomly assigned activity session. A larger survey and battery of cognitive tests will be completed at the beginning of the first appointment and at the conclusion of the third appointment.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Comparador activo: Aerobic Exercise Only
Participants in the Aerobic Exercise Only arm will engage in three separate 20-minute sessions comprised of a 5-minute, resistance-free warm-up, and 15 minutes of moderate stationary aerobic cycling on a Cybex bike #525C (50-70% age-predicted heart rate max). Each session will be followed by 20 minutes of uninterrupted quiet rest. The bike will provide feedback including speed, rotations per minute, and time.
This intervention will combine 20 minutes of moderate aerobic exercise followed by 20 minutes of quiet rest.
Comparador activo: Relaxation Only
Participants in the Relaxation Only arm will complete three separate 20-minute sessions of relaxation using a commercial wearable neurofeedback (headband) device. The device's accompanying software (connected to the headband through Bluetooth) encourages breathing strategies in response to recorded brain wave activity. Real time auditory feedback includes sounds of calm (soft) or loud winds in response to detected brain activity. A visual report of affective states and the user's brain activity is given (alpha and beta waves). Participants will also be asked to take part in 20 minutes of uninterrupted quiet rest in order to match the time of the aerobic only condition.
This intervention will combine 20 minutes of mindfulness-based relaxation training followed by 20 minutes of quiet rest.
Experimental: Aerobic Exercise and Relaxation
Participants in the Aerobic Exercise and Relaxation arm will complete the three separate 20-minute aerobic exercise sessions (identical to the aerobic exercise only condition) followed by the same 20-minute neurofeedback-guided mindfulness training (identical to the relaxation only condition).
This intervention will combine 20 minutes of moderate aerobic exercise followed by 20 minutes of mindfulness training.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Piper Fatigue Scale
Periodo de tiempo: This will be assessed on day 1 (baseline), day 2 and day 3 (post-testing), both before and after randomized activities.
The Piper Fatigue Scale requires respondents to select their answers according to a "0" (most positive or desirable response) to "10" (most negative, fatigue is having a strong impact) scale. A total fatigue score is calculated by summing each of the 12 responses and dividing by 12. Accordingly, a total fatigue change score of 0 corresponds to no fatigue, a score of 1-3 is labeled as mild, 4-6 is labeled as moderate, and 7-10 is labeled as severe. The total scores from each of the three days will be used to calculate an overall fatigue score, which will be used to assess group level differences across averages. Our operational definition of overall fatigue in this outcome is the average score across each group.
This will be assessed on day 1 (baseline), day 2 and day 3 (post-testing), both before and after randomized activities.

Medidas de resultado secundarias

Medida Descripción
Periodo de tiempo
Perceived Mental Fatigue
Periodo de tiempo: The PMFQ will be assessed on day 1 (baseline), day 2, and day 3 (post-testing).
The Perceived Mental Fatigue Questionnaire (PMFQ) is a novel inventory using 7-item Likert scale ( e.g., "My thinking requires effort," 1 = Not at all to 5 = Very true). Participants are asked to reflect on their current level of mental fatigue. The 7 items from PMFQ are summed together to create a composite fatigue value. The total scores from each of the three days will be used to calculate an overall fatigue score, which will be used to assess group level differences across averages. Our operational definition of overall fatigue in this outcome is the average score across each group.
The PMFQ will be assessed on day 1 (baseline), day 2, and day 3 (post-testing).
Energy subscale of AD ACL-SAI
Periodo de tiempo: This will be assessed following randomized activities on Day 1 (baseline), Day 2, and Day 3 (post-testing).
The AD ACL-SAI asks respondents to select how they relate to a specific adjective in the moment by choosing between 4 answer options (1=not at all, 2=moderately so, 3=somewhat, and 4=very much so). Each of the 5 items in the Energy subscale are summed together to create an overall Energy fatigue score.The total scores from each of the three days will be used to calculate an overall energy score, which will be used to assess group level differences across averages. Our operational definition of overall energy in this outcome is the average score across each group.
This will be assessed following randomized activities on Day 1 (baseline), Day 2, and Day 3 (post-testing).
Tiredness subscale of AD ACL-SAI
Periodo de tiempo: This will be assessed following randomized activities on Day 1 (baseline), Day 2, and Day 3 (post-testing).
The AD ACL-SAI asks respondents to select how they relate to a specific adjective in the moment by choosing between 4 answer options (1=not at all, 2=moderately so, 3=somewhat, and 4=very much so). Each of the 5 items in the Tiredness subscale are summed together to create an overall Tiredness fatigue score. This will be used to calculate a change score. The total scores from each of the three days will be used to calculate an overall tiredness score, which will be used to assess group level differences across averages. Our operational definition of overall tiredness in this outcome is the average score across each group.
This will be assessed following randomized activities on Day 1 (baseline), Day 2, and Day 3 (post-testing).
Attention- Assessed by Flanker Inhibitory Control and Attention task from the NIH toolbox
Periodo de tiempo: This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
In the Flanker task participants focus on a given stimulus while inhibiting attention to stimuli flanking it. Participants see a row of 5 arrows and choose the button that matches the direction the middle arrow is pointing. This test yields a standardized accuracy and processing speed change score.
This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
Working Memory- Assessed by Picture Sequence task from the NIH toolbox
Periodo de tiempo: This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
The Picture Sequence tasks asks participants to remember a specific order of events as demonstrated by the task itself on a screen. At the conclusion of the demonstration, the events are scrambled and the participants are instructed to place them back in the correct order. This task yields a standardized accuracy change score.
This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
Cognitive Flexibility and Attention- Assessed by Dimensional Change Card Sort Task from the NIH toolbox
Periodo de tiempo: This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
In the Dimensional Change Card Sort Task, participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). The ensuing "switch" trials are also employed, in which the participant is required to change the dimension being matched. For example, after 4 straight trials matching on shape, the participant may be asked to match on color on the next trial and then go back to shape, thus requiring the cognitive flexibility to quickly choose the correct stimulus. The NIH toolbox automatically calculates an overall raw score, which takes into account both accuracy and reaction time, used to create a change score.
This will be assessed prior to randomized activities on day 1 (baseline), and day 3 (post-testing)
Program Evaluation - Perceived Usefulness
Periodo de tiempo: This will be assessed on day 3.
All participants will complete an adapted version of Davis (1989) and Davis et al., (1989) perceived usefulness questionnaire (e.g., "Using the technology-delivered relaxation training program improved my thinking"). These 5 items will be measured using a 7-point Likert scale (1 = Strongly disagree, 4 = Neutral, 7 = Strongly agree) and will assess attitudes towards the technology-delivered relaxation-training program. The 5 item's responses will be averaged and then used for a total perceived usefulness score.
This will be assessed on day 3.
Program Evaluation - Perceived Ease of Use
Periodo de tiempo: This will be assessed on day 3.
All participants will complete an adapted version of Davis (1989) and Davis et al., (1989) perceived ease of use questionnaire (e.g., "I found the technology-delivered relaxation training program to be easy to use"). These 5 items will be measured using a 7-point Likert scale (1 = Strongly disagree, 4 = Neutral, 7 = Strongly agree) and will assess attitudes towards the technology-delivered relaxation-training program. The 5 item's responses will be averaged and then used for a total perceived usefulness score.
This will be assessed on day 3.
Program Evaluation - Enjoyment
Periodo de tiempo: This will be assessed on day 3.
An evaluation of participants' enjoyment of the trial will also be included. Five questions (e.g., I enjoyed using the mindfulness training device) using a 7-point Likert scale (1 = Not at all, 4 = Neutral, 7 = Completely) will be administered. The 5 item's responses will be averaged and then used for a total perceived usefulness score.
This will be assessed on day 3.
Program Evaluation - Satisfaction
Periodo de tiempo: This will be assessed on day 3.
An evaluation of participants' satisfaction with components of the trial will also be included. Five questions (e.g., I am satisfied with the outcomes experienced following mindfulness training) using a 7-point Likert scale (1 = Not at all, 4 = Neutral, 7 = Completely) will be administered. The 5 item's responses will be averaged and then used for a total perceived usefulness score.
This will be assessed on day 3.
Program Evaluation - Open Ended
Periodo de tiempo: This will be assessed on day 3.- focusing on thoughts of the program over the three appointment days, in a 1-week period.
An open ended evaluation of participants' experience with the trial will also be included. This qualitative question will ask participants to expand upon their overall likes and dislikes, recommendations, and modifications will be included. Open ended responses will be used to design and apply future interventions in this area.
This will be assessed on day 3.- focusing on thoughts of the program over the three appointment days, in a 1-week period.
