Brief Summary

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.

Conditions

Balance; Warm-up; Proprioception; Agility

Keywords

Agility; Balance; Muscle Warm-up; Proprioception; Vertical jump

Outcome Measures

Primary Outcomes (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 .

  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)

• Sargent Vertical Jump Test

  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.

Other Outcomes (2)

• T-Test for Agility

  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.

• Dynamic Balance Test (Y-Balance Test)

  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.

Exercise Program

EXPERIMENTAL

Other: three warming phases of the muscle

Interventions

three warming phases of the muscle OTHER

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.
