Eligibility
Inclusion criteria
Inclusion criteria: Subjects meeting the following criteria are proposed for inclusion: 1. Healthy adults aged 18–35 years, regardless of gender. 2. No regular upper limb resistance training experience in the past 12 weeks. 3. No history of musculoskeletal injuries to the elbow, shoulder, wrist, or upper limbs within the past 6 months. 4. Able to understand the research protocol and voluntarily sign the informed consent form. 5. Able to collaborate in performing isokinetic centrifugation exercises, continuous interventions, and follow-up measurements. 6. During the study period, participants agreed to avoid additional upper limb resistance training, strenuous exercise, massage, thermotherapy, cryotherapy, analgesics, or any other interventions that may interfere with recovery. 7. Female subjects must have a relatively regular menstrual cycle and agree to report the phase of their menstrual cycle in the study records; baseline testing and centrifugal exercise-induced tests should preferably be conducted during the early follicular phase (i.e., days 2–7 of menstruation) .
Exclusion criteria
Exclusion criteria: 1. History of upper limb fractures, tendon injuries, nerve injuries, severe muscle strains, or surgical interventions. 2. Presence of neurological disorders, muscular diseases, or rheumatic/immune diseases that affect upper limb motor function. 3. Presence of cardiovascular diseases, severe metabolic disorders, uncontrolled hypertension, or other conditions that make high-intensity eccentric exercise unsuitable. 4. Recent presence of acute inflammation, infection, fever, or general malaise. 5. Do not take nonsteroidal anti-inflammatory drugs, analgesics, muscle relaxants, or any other medications that may affect pain and inflammatory responses within 7 days prior to the study. 6. Engaged in intense upper limb exercise, resistance training, massage, thermotherapy, cryotherapy, or other recovery interventions within 48–72 hours prior to the study. 7. Presence of skin lesions, dermatitis, infection, sensory impairment, or allergy to conductive materials. 8. Implantation of a cardiac pacemaker, metallic internal fixation devices, or other implantable devices unsuitable for radiofrequency/electrical therapy intervention. 9. Women during pregnancy, lactation, or preconception period. 10. Female subjects with significantly irregular menstrual cycles, dysmenorrhea severely affecting athletic performance, or recent use of medications that may substantially alter hormone levels without achieving stable control.
