About this trial

Study Design:

This study was approved by the Human Experiment Ethics Committee of Chengdu Sport University (No: 2103).

Based on previous research data, G-power software was used to calculate that at least 40 samples were needed.

Participants:

A total of 45 track and field athletes from Sichuan Province, China, were recruited during the off-season in 2024. They were randomly assigned to the vibration group, kinesio taping group, combined group, and control group.

All participants signed informed consent forms and adhered to the Declaration of Helsinki.

DOMS Modeling:

Following previous research, a delayed onset muscle soreness (DOMS) model for athletes\' knee joints was established through downhill running.

Detailed oxygen uptake tests were conducted on all participants one week before DOMS modeling, and records were made one week after DOMS modeling.

Intervention Measures:

The vibration group received vibration training immediately after DOMS modeling.

The kinesio taping group had Y-shaped kinesio taping applied 30 minutes before DOMS modeling.

The combined group received both vibration training and kinesio taping simultaneously.

Assessment Methods:

The degree of pain at the DOMS site for participants was evaluated using a Visual Analogue Scale (VAS).

The concentration of creatine kinase (CK) in the serum of participants was detected using an RT-9600 automatic biochemical analyzer, and serum interleukin-6 (IL-6) was detected by enzyme-linked immunosorbent assay (ELISA).

An IsoMed 2000 isokinetic tester was used to perform a 60°/s extension test on the participants\' knees.

Data Collection:

VAS scores, serum CK and IL-6 levels, and peak torque of knee extension were collected at different time points before and after DOMS modeling.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Athletes who performed regular training, ranked in the top 3 in a provincial competition and trained at least 5days per week, with a minimum of 4 h each day.

This training encompassed, but was not limited to, strength training, endurance training, skill drills and competitive preparation.

This study was in line with the Declaration of Helsinki, and the participants were aware of the study intention and signed informed consent.

Disqualifiers

Lower limb joint injury and systematic exercise training in the last week.

Parallel

Treatments tested in this trial

  • vibration training

    Other intervention

    After modelling, when the vibration platform is closed, all participants of the control group completed the same action as vibration training.

  • vibration training

    Other intervention

    For the vibration group, vibration training was performed immediately after DOMS modelling.

  • Y-shaped kinesio taping

    Other intervention

    For the kinesio group, Y-shaped kinesio taping was performed 30 min before DOMS modelling.

  • Combined vibration training and Y-shaped kinesio taping

    Other intervention

    For the combined group, the vibration group and kinesio group interventions were performed simultaneously.

Trial outcomes

Primary outcomes

1

VAS Testing

The pain degree of the participants at the DOMS site was evaluated by VAS. The participants were asked to draw a vertical line on a 10 cm straight line (0 cm was painless, and 10 cm was the most painful, scored 0-10. The left and right knee joints were drawn once each, and the mean was processed.

Time frame
7 Days
2

Serum IL-6 Testing

About 3 mL of venous blood was collected from the participants, and the CK concentration of the participants at five time points was detected by using an RT-9600 automatic biochemical analyser (kit provided by Shanghai Lanxing Biotechnology Co., Ltd.).

Time frame
7 Days
3

CK Testing

About 3 mL of venous blood was collected from the participants. Serum IL-6 was detected by enzyme-linked immunosorbent assay (kit provided by Shanghai Varan Biotechnology Co., Ltd.).

Time frame
7 Days
4

Isokinetic Knee Testing

An IsoMed 2000 isokinetic tester from Germany was used to perform 60°/s (three times) extension test on the participants' knee. The participants were in a sitting position, and the trunk and hip joints were fixed with a wide binding. The knee joint extension mode was selected with the joint activity of 80°, and the analytical index was peak torque; the test data were averaged on the left and right sides.

Time frame
7 Days
