Remotely Supervised Exercise During Chemotherapy in Women With Breast Cancer
Effect of Remotely Supervised Combined Aerobic and Resistance Exercise Training on Physical Health and Quality of Life in Women With Breast Cancer During Chemotherapy
調査の概要
詳細な説明
Participants in the RE-CARE intervention group will be scheduled for 2-3 training sessions per week on non-consecutive days throughout the entire chemotherapy period (~24 weeks), ensuring no more than 48 hours elapse between two sessions. Each participant will first complete a 30-40 minute individualized introductory session to learn correct exercise techniques using the training equipment.
Each aerobic high intensity interval training session will begin with a 6-minute warm-up at a self-selected walking speed gradually increasing to moderate intensity (approximately 60-70% HRmax), corresponding to 4 on the Modified Borg scale (moderate perceived exertion) by the end of the warm-up. Following this, the main segment will consist of four 4-minute walking intervals at 85-95% HRmax (7-8 on the Modified Borg scale). Each 4-minute high-intensity interval will be interspersed with 3 minutes of active recovery at 55-70% HRmax (4 on the Modified Borg scale). The total duration of session will therefore be 34 minutes.
For resistance training, participants will perform 3-4 sets of 6 repetitions, with a 2-minute rest interval between sets. The initial workload will be set at 70% of the participant's estimated one-repetition maximum (1RM), corresponding to 6-7 on the Modified Borg scale, and will be increased to 80% (7-8 on the Modified Borg scale) once participants are able to complete more than 6 repetitions. The RT program will target major muscle groups of the legs, shoulders, and arms. Each RT session will last 35 minutes in total, including a 6-minute warm-up and a 3-minute cool-down.

Change in cardiorespiratory functioning, assessed by incremental test according to the University of Northern Colorado Cancer Rehabilitation Institute (UNCCRI) Treadmill protocol
時間枠：From baseline to 6 months after the intervention
|
The UNCCRI Treadmill Protocol includes twenty-one 1-minute stages, with systematic increments in treadmill speed and/or grade at each stage.
Outcome measures will include maximal oxygen uptake (max ml/kg/min) and ventilatory variables such as minute ventilation (L/min) and respiratory exchange ratio (RER).
Heart rate (beats/min) will be continuously monitored throughout each test using a heart rate monitor.
Time to exhaustion, treadmill speed, and treadmill grade will be recorded at the point of test termination.
Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models.

Change in Health-Related Quality of Life, assessed by European Organisation for Research and Treatment of Cancer Core Quality of Life questionnaire-Core 30 (EORTC QLQ-C30)
時間枠：From baseline to 6 months after the intervention
|
Participants will be asked to complete the EORTC QLQ-C30, a 30-item questionnaire, electronically. This instrument includes a global health status/quality-of-life scale and multiple functional subscales (physical, emotional, cognitive, social, and role functioning). It further incorporates several symptom subscales assessing fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties. Patients respond to the items using Likert scale (1 = "Not at all," 2 = "A little," 3 = "Quite a bit," and 4 = "Very much"). All scales and single-item measures yield scores ranging from 0 to 100%. For the functional scales, higher scores indicate better functioning, but for the symptom scales, higher scores reflect greater symptom severity. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models. |

Change in cognitive functioning, assessed by Stroop test
時間枠：From baseline to 6 months after the intervention
|
Stroop test assesses the ability to inhibit cognitive interference, which occurs when the processing of a stimulus feature affects the simultaneous processing of another attribute of the same stimulus. It measures attention, processing speed, cognitive flexibility and working memory. Participants will be shown color words printed in inconsistent ink colors (for example, the word "red" printed in green ink). They will be instructed to name the ink color rather than read the word. Two primary kinds of units will be used for measurement: time and number of errors. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models. |

Change in cognitive functioning, assessed by The Wisconsin Card Sorting Test
時間枠：From baseline to 6 months after the intervention
|
The Wisconsin Card Sorting Test was developed to assess abstraction and the ability to shift cognitive strategies in response to changing environmental contingencies. It is considered a measure of executive function. During the tests four cards (a red triangle, two green stars, three yellow crosses, and four blue circles) will be placed in front of the participant. The participants will be shown a set of response cards that can be matched to the stimulus cards based on color, shape or number. Multiple parameters will be evaluated: 1) number of correct sorts, 2) categories 3) perseverative errors, 4) set-loss errors. Data obtained will be analyzed using repeated-measures analysis and linear mixed-effects models. |
