About this study

Official title: Effects of Muscle Warm-Up Phases on Proprioception, Vertical Jump, Agility, and Balance in Professional Youth Soccer Players: A Randomized Study

Purpose: This study aimed to examine the effects of different muscle warm-up phases on knee joint proprioception, vertical jump, agility, and balance in professional youth soccer players.

Methods: Twenty-five professional youth football players under 18 were assessed during muscle rest, warm-up, and fatigue phases using tests measuring knee proprioception, dynamic balance, explosive power, and agility.

Read the detailed description

Purpose:

The purpose of this study was to investigate how different phases of muscle warm-up affect knee joint proprioception, vertical jump performance, agility, and dynamic balance in professional youth soccer players. Understanding these effects is critical for optimizing warm-up protocols to enhance athletic performance and reduce injury risk in this population.

Methods:

Twenty-five male professional youth football players under the age of 18 (mean age 16.5 ± 1.2 years) were randomly selected for this study. Each participant underwent assessments during three distinct muscle states: resting, after warm-up, and post-training fatigue. Knee joint proprioception was evaluated at a 30° angle using a digital inclinometer to measure joint position sense accuracy. Dynamic balance was assessed through the Y-balance test in three directions: anterior, posteromedial, and posterolateral. Explosive power was measured using the Sargent vertical jump test, while agility was tested with the T-test. All measurements were performed in each muscle condition to compare performance across the different warm-up phases.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • three warming phases of the muscleOther

    All assessments will be measured in three warming phases of the muscle. The first phase is the Rest state (Cold state), which is the phase before the training begins. In this phase, the athlete has not warmed up. The second phase is the "Warming state," where the athlete has started the training and has warmed up for 20 minutes. The third phase is the "Post-Training Phase," which occurs 10 minutes after the completion of a 90-minute training session. Measurements will be taken for all three phases.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proprioception Test

    Knee joint proprioception was assessed using a Baseline Digital Inclinometer (Fabrication Enterprises Inc., USA). Active joint position sense (JPS) of the dominant knee was measured with this device. Participants were seated in a 90° hip and knee flexion position. Initially, the researcher passively positioned the participant's knee at 30° of flexion with eyes open, instructing the participant to memorize the angle. The participant was then asked to close their eyes and actively replicate the target position. The angular deviation from the target was recorded as the proprioceptive error. This procedure was repeated three times, and the mean error was used for analysis .

    Measured: It was measured separately in all three phases of exercise. Baseline (resting phase), immediately after the warm-up phase, and immediately after the fatigue phase.

Secondary outcomes (1)
  1. Sargent Vertical Jump Test

    The Sargent Jump Test (SJT) was used to evaluate the explosive power of the lower extremities. Participants stood side-on to a wall and extended their dominant arm upward to mark their maximum reach height while standing flat-footed. This point was recorded as the baseline. From a standing position, participants performed a maximal vertical jump and touched the wall at the peak of their jump. The difference between the jump reach and the standing reach height was calculated and recorded as the jump height. Three trials were conducted, and the highest value was used for analysis. A higher score indicates better performance .

    Measured: It was measured separately in all three phases of exercise.Baseline (resting phase), immediately after the warm-up phase, and immediately after the fatigue phase.

Questions about this trial

What is this clinical trial studying?

A study testing three warming phases of the muscle in people with Agility and Balance, run by Necmettin Erbakan University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proprioception Test (time frame: It was measured separately in all three phases of exercise. Baseline (resting phase), immediately after the warm-up phase, and immediately after the fatigue phase.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07284706, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Dec 2025.
