Sport sampling is recommended to promote fundamental movement skill acquisition and physical activity. In contrast, sport specialization is associated with musculoskeletal injury risk, burnout, and attrition from sport. There is limited evidence to support the influence of sport sampling on neuromuscular control, which is associated with injury risk, in youth athletes.
Athletes who participated in only 1 sport during the previous year would demonstrate higher Landing Error Scoring System (LESS) scores than their counterparts.
Cross-sectional study.
Level 3.
A total of 355 youth athletes (age range, 8-14 years) completed a test session with a jump-landing task, which was evaluated using the LESS. Participants were categorized as single sport (SS) or multisport (MS) based on their self-reported sport participation in the past year. Their duration of sport sampling (low, moderate, high) was determined based on their sport participation history. Participants were dichotomized into good (LESS <5) or poor (LESS ≥5) categories. Chi-square tests were performed to evaluate for the association between control category (good, poor) and participation (MS, SS), as well as sport-sampling duration (low, moderate, high).
The MS group was 2.5 times (95% CI, 1.9-3.1) as likely to be categorized as having good control compared with the SS group (χ = 10.10, P < 0.01). Recreational participants in the "high" sport-sampling duration group were 5.8 times (95% CI, 3.1-8.5) and 5.4 times (95% CI, 4.0-6.8) as likely to be categorized as having good control compared with the moderate and low groups (χ = 11.20, P < 0.01).
Sport sampling at a young age is associated with improved neuromuscular control, which may reduce injury risk in youth athletes.
Youth athletes should be encouraged to try participating in multiple sports to enhance their neuromuscular control and promote long-term physical activity.
运动抽样被推荐用于促进基本运动技能的获得和身体活动。相比之下，专项运动与肌肉骨骼受伤风险、倦怠和退出运动有关。有有限的证据支持运动抽样对神经肌肉控制的影响，而神经肌肉控制与受伤风险有关，在青年运动员中。
在前一年只参加过一项运动的运动员的着陆错误评分系统（LESS）得分会高于他们的同龄人。
横断面研究。
3 级。
共有 355 名青年运动员（年龄 8-14 岁）完成了一次跳跃着陆任务测试，使用 LESS 进行评估。参与者根据他们过去一年的自我报告的运动参与情况被归类为单一运动（SS）或多运动（MS）。根据他们的运动参与历史确定他们的运动抽样时间（低、中、高）。参与者被分为良好（LESS <5）或不良（LESS ≥5）类别。进行卡方检验，以评估控制类别（良好、不良）与参与（MS、SS）以及运动抽样时间（低、中、高）之间的关系。
与 SS 组相比，MS 组更有可能被归类为具有良好控制的可能性是其 2.5 倍（95%CI，1.9-3.1）（χ=10.10，P < 0.01）。在“高”运动抽样时间组中，娱乐参与者更有可能被归类为具有良好控制的可能性是中组和低组的 5.8 倍（95%CI，3.1-8.5）和 5.4 倍（95%CI，4.0-6.8）（χ=11.20，P < 0.01）。
年轻时进行运动抽样与改善神经肌肉控制有关，这可能会降低青年运动员的受伤风险。
应鼓励青年运动员尝试参加多种运动，以增强他们的神经肌肉控制能力并促进长期的身体活动。
