简要总结
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.
详细描述
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.

结局指标
主要结局
Proprioception Test
时间窗: 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.
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 .
