Inclusion criteria
Inclusion criteria: 1. Age 18–35 years, 100 males and 100 females, totaling 200 participants. 2. Physically healthy, with no Explicit cardiovascular, respiratory, neuromuscular, musculoskeletal system diseases, or other medical conditions or health issues that would render them unsuitable for exercise testing. 3. Possess a certain level of exercise foundation, enabling them to safely complete standardized warm-up, specific conditioning activities (CA), countermovement jumps (CMJ), and other tests under the guidance of researchers. 4. Willing to complete the entire experimental protocol as required by the study, including two laboratory visits for testing and completion of relevant questionnaires and record forms. 5. Voluntarily participate in this study and have signed a written informed consent form. 6. Able to control recent training, sleep, caffeine intake, alcohol consumption, smoking, and other related behaviors as required prior to testing. 7. Participants may have diverse exercise backgrounds and training experiences, including but not limited to different sport-specific participation histories, training duration, training frequency, training continuity, length of training hiatus, and current physical activity levels. This study allows for and focuses on individual variability arising from differences in exercise background. However, all participants must possess basic motor abilities, action comprehension abilities, and experimental cooperation abilities to safely complete all tests and intervention protocols specified in this study.
Exclusion criteria
Exclusion criteria: 1. Presence of diseases affecting the cardiovascular system, respiratory system, neuromuscular system, or musculoskeletal system; recent exercise-related injuries, pain; or other health issues that may impact test safety or result interpretation. 2. Use of medications, supplements, or other interventions that may affect neural excitability, heart rate response, muscle function, or exercise performance. 3. Significant intolerance or contraindications to study-related experimental conditions, such as sensitivity or intolerance to caffeine, or other situations unsuitable for exposure to the corresponding experimental conditions. 4. Failure to control sleep, training, diet, caffeine intake, alcohol consumption, smoking, or other relevant behaviors as required prior to the experiment. 5. Inability to understand experimental requirements, inability to cooperate in completing the prescribed procedures, or researcher judgment that the individual is not capable of safely completing the study's tests and interventions. 6. Occurrence of significant discomfort, adverse reactions, injury, withdrawal during the experiment, or failure to complete key testing procedures. 7. Severe missing data that prevents inclusion in subsequent statistical analysis. 8. Other situations deemed unsuitable for inclusion in the study by the researcher.
