简要总结
This study aims to develop and validate an innovative dynamic 9-square grid management model to improve aerobic capacity (AC) and physical activity participation among graduate students. The model integrates real-time exercise volume (quantified via smart wearable devices) and aerobic capacity (assessed by 12-minute run tests) into a two-dimensional grid, stratifying participants into five tiers for differentiated interventions.
Using a 2 × 3 mixed-design (feedback frequency: weekly vs. monthly; time points: baseline/mid/post-intervention), 32 healthy graduate students are randomized into two groups:
Weekly feedback (dynamic position updates + tailored optimization strategies).
Monthly feedback (position updates at monthly intervals).
Key components include:
Multimodal assessment: Objective exercise metrics (Huawei Band 6), AC (12-min run), psychological scales (Exercise Identity Scale, Self-Efficacy for Exercise Scale).
Tiered intervention: Customized strategies based on grid positioning (e.g., "Star Talent" optimization vs. "Urgent Attention" support).
Primary outcomes: Changes in AC, total exercise volume (TEV), exercise identity, and self-efficacy.
The study seeks to determine whether weekly dynamic feedback outperforms monthly feedback in sustaining behavioral change and enhancing physiological adaptation. Ethical approval was obtained from Anqing Normal University (AQNU2024110).

入选标准
- •Graduate students aged between 18 and 30 years.
- •Completion of the Physical Activity Readiness Questionnaire (PAR-Q) to confirm readiness for exercise.
- •Completion of a sociodemographic questionnaire (including age, gender, and education level).
- •Confirmation of absence of exercise contraindications (e.g., conditions that may prevent safe participation in physical activity).
- •Confirmation of absence of cardiovascular disease.
- •Confirmation of absence of recent lower-limb injuries (occurring within the past 3 months or less).
- •Confirmation of absence of chest pain symptoms.
- •Ability to provide written informed consent for voluntary participation.
排除标准
- •Presence of exercise contraindications identified through the PAR-Q or clinical evaluation.
- •History or diagnosis of cardiovascular disease (e.g., heart conditions, stroke, or related disorders).
- •Recent lower-limb injuries (e.g., fractures, sprains, or surgeries) within the past 3 months.
- •Experience of chest pain symptoms (e.g., angina or discomfort during physical exertion).
- •Inability to complete the required questionnaires or assessments due to cognitive or language barriers.
- •Presence of any uncontrolled chronic condition that could interfere with exercise participation, as determined by the researchers during screening.
