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.

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.

Conditions

• Agility
• Balance
• Warm-up
• Proprioception

Interventions

Type	Name	Description
OTHER	three warming phases of the muscle	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.
