Artificial Intelligence (AI)-Based Personalized Exercise Coaching for Patients With Breast Cancer

21. september 2026 opdateret af: Kunwei Shen, Shanghai Jiao Tong University School of Medicine

Effect of an Artificial Intelligence-Based Personalized Exercise Coaching System on Exercise Adherence and Quality of Life in Patients With Breast Cancer: A Randomized Controlled Trial

This prospective, single-center, randomized controlled trial aims to evaluate the effectiveness and safety of an artificial intelligence (AI)-based personalized exercise coaching system in female breast cancer survivors who have completed major cancer treatment and are clinically stable. A total of 100 eligible participants will be randomly assigned in a 1:1 ratio to either an AI-based exercise coaching group or a conventional exercise guidance group. Participants in the intervention group will receive personalized exercise recommendations generated by the AI exercise coaching system, with exercise data collected and used for dynamic adjustment of exercise guidance. Participants in the control group will receive conventional exercise recommendations provided by healthcare professionals. The intervention will last for 6 months. Exercise adherence will be evaluated as the primary outcome. Secondary outcomes will include quality of life, psychological status, physical function, exercise-related adverse events, and laboratory and metabolic parameters.

Detaljeret beskrivelse

Regular physical activity is recommended for patients with cancer and may improve physical function, psychological well-being, and quality of life. However, conventional exercise guidance may be limited by insufficient personalization, limited professional resources, and difficulties in continuously monitoring exercise behavior.

The AI-based exercise coaching system evaluated in this study is designed to provide personalized exercise recommendations and dynamically adjust exercise guidance based on individual characteristics and exercise data. The system integrates exercise-related knowledge and uses wearable devices to collect exercise data for monitoring and feedback.

This study is a prospective, single-center, open-label, randomized controlled trial conducted among female patients with breast cancer who have completed major cancer treatment and are clinically stable. One hundred eligible participants will be randomized in a 1:1 ratio to the AI-based exercise coaching group or the conventional exercise guidance group.

Participants assigned to the AI-based exercise coaching group will follow individualized exercise programs generated by the system and will upload exercise data to enable dynamic guidance and adjustment. Participants assigned to the control group will receive general exercise recommendations from healthcare professionals.

The intervention period will be 6 months. Assessments will be conducted at baseline, 3 months, and 6 months. The primary outcome will be exercise adherence. Secondary outcomes will include quality of life, psychological status, physical function, exercise-related safety outcomes, and laboratory and metabolic parameters.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: The AI-Based Exercise Coaching Group

Participants assigned to this group will use an AI-based exercise coaching system for 6 months. The system will generate individualized exercise recommendations based on participant characteristics and health-related information. Exercise data will be collected and uploaded to the system, allowing exercise recommendations to be dynamically adjusted according to participants' exercise performance and status. Participants will also receive regular follow-up during the intervention period.

Participants will receive individualized exercise recommendations generated by an AI-based exercise coaching system. The system provides personalized exercise guidance and uses exercise data collected to monitor exercise performance and dynamically adjust recommendations. The intervention will be delivered for 6 months.

Aktiv komparator: The Control Group

Participants assigned to the control group will receive conventional exercise guidance from healthcare professionals based on routine clinical practice and professional experience, including general recommendations such as approximately 150 minutes of moderate-intensity aerobic exercise per week. Participants will receive regular follow-up during the 6-month study period.

General exercise recommendations will be provided by healthcare professionals according to routine clinical practice.

Foranstaltningsbeskrivelse
Tidsramme
Exercise Adherence
Tidsramme: 6 months

Exercise adherence will be calculated as the ratio of the participant's actual exercise frequency to the recommended exercise frequency during the intervention period, expressed as a percentage. Exercise adherence will be compared between the AI-based exercise coaching group and the conventional exercise guidance group.

Tidsramme
Change in Health-Related Quality of Life
Tidsramme: Baseline, 3 months, and 6 months

Health-related quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Scores will be calculated according to the EORTC scoring procedures, with domain scores transformed to a 0-100 scale. Higher scores on functional scales and global health status indicate better functioning or quality of life, whereas higher scores on symptom scales indicate greater symptom burden.

Baseline, 3 months, and 6 months
Change in Anxiety Symptoms
Tidsramme: Baseline, 3 months, and 6 months

Anxiety symptoms will be assessed using the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A). The HADS-A score ranges from 0 to 21. Higher scores indicate more severe anxiety symptoms.

Baseline, 3 months, and 6 months
Change in Depressive Symptoms
Tidsramme: Baseline, 3 months, and 6 months

Depressive symptoms will be assessed using the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). The HADS-D score ranges from 0 to 21. Higher scores indicate more severe depressive symptoms.

Baseline, 3 months, and 6 months
Change in Peak Oxygen Uptake
Tidsramme: Baseline, 3 months, and 6 months

Peak oxygen uptake (VO₂peak) will be measured by cardiopulmonary exercise testing (CPET) on an electronically braked cycle ergometer, using a CORTEX MetaLyzer 3B-R3 metabolic cart, during a symptom-limited incremental exercise protocol.
