Brief summary
This study aims to examine whether a physical training program designed based on individual interests can improve exercise adherence and physical fitness among college students, and to explore whether positive affective experience plays a mediating role in this process. College student participants will be randomly assigned to either an interest-based physical training group or a control group (conventional physical education or no intervention). The interest-based training program includes personalized exercise activities such as team games, fitness challenges, and recreational sports, designed to enhance intrinsic motivation. The intervention will last for 12 weeks. Primary outcome measures include exercise adherence (e.g., attendance rate, dropout rate) and physical fitness (e.g., cardiorespiratory endurance, muscular strength, flexibility). Secondary outcome measure is positive affective experience assessed by standardized questionnaires. Mediation analysis will be conducted to test whether the effect of interest-based training on adherence and fitness is mediated by positive affective experience. The study has been approved by the Ethics Committee of the Academic Committee, Capital University of Physical Education and Sports (Approval Number:2025A055). All participants will provide informed consent before enrollment.
Interventions
BEHAVIORALInterest-Based Physical Training；
A 12-week physical training program tailored to individual interests, including team games, fitness challenges, and recreational sports. Sessions are conducted1 times per week, each lasting 90 minutes.
BEHAVIORALRegular Physical Training
Standard physical training sessions following the regular university curriculum, without individualized interest-based design. Frequency and duration are matched to the experimental group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Exercise Adherence Questionnaire - Total Score | Baseline, 6 weeks, and 12 weeks (end of intervention) | A 14-item self-report questionnaire measuring exercise adherence across three dimensions: Behavioral Habits (items 1-4, 4 items), Effort Investment (items 5-9, 5 items), and Emotional Experience (items 10-14, 5 items). Each item is rated on a 5-point Likert scale (1=strongly disagree to 5=strongly agree). Total score ranges from 14 to 70, with higher scores indicating better exercise adherence. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Vital Capacity | Baseline and 12 weeks | Maximum amount of air exhaled after maximal inhalation, measured in milliliters using a spirometer. Higher value indicates better respiratory function. |
| 50-meter Sprint Time | Baseline and 12 weeks | Time in seconds to complete a 50-meter sprint. Lower time indicates better speed. |
| Cardiorespiratory Endurance (800m run for females, 1000m run for males) | Baseline and 12 weeks | Time in minutes to complete the distance (800m for females, 1000m for males). Lower time indicates better endurance. |
| Sit-and-Reach Test | Baseline and 12 weeks | Distance reached in centimeters while sitting and reaching forward. Higher distance indicates better flexibility. |
| Standing Long Jump | Baseline and 12 weeks | Distance jumped in centimeters from a standing start. Greater distance indicates better lower body explosive strength. |
| Pull-ups (males) | Baseline and 12 weeks | Number of pull-ups completed. Higher number indicates better upper body muscular endurance. |
| Sit-ups (females) | Baseline and 12 weeks | Number of sit-ups completed in one minute. Higher number indicates better abdominal muscular endurance. |
