研究目的: |
本研究旨在探讨抗阻训练背景下棒球运动员挥棒动力链特征及其训练前后变化,分析峰值棒头速度、地面反作用力应用、前腿制动冲量、外部绕垂直轴角冲量、骨盆—躯干分离及近端—远端时序等生物力学指标的变化及其与棒速表现的关系。同时,本研究将在训练后测阶段分析最大高度跳深制动—推进力学指标与挥棒动力链及棒头速度之间的关联,以建立下肢制动—推进能力、地面力应用、旋转动力学和棒速表现之间的专项生物力学解释框架,为棒球运动员抗阻训练和专项技术反馈提供依据。 |

Objectives of Study: |
This study aims to investigate the kinetic chain characteristics of baseball swinging and their pre–post training changes under a resistance training context. Specifically, this study will examine changes in peak bat speed, ground reaction force application, lead-leg braking impulse, external angular impulse about the vertical axis, pelvis–trunk separation, and proximal-to-distal sequencing, and analyze their associations with swing performance. In addition, post-training drop-jump braking–propulsive mechanical variables will be examined in relation to swing kinetic chain variables and peak bat speed, in order to establish a sport-specific biomechanical framework linking lower-limb braking–propulsive ability, ground force application, rotational dynamics, and bat speed performance. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
本研究不公开含个人身份识别信息的原始数据。主要研究成果发表后,在不违反知情同意、隐私保护和学校数据管理规定的前提下,可根据合理学术申请,经项目负责人审核后提供去标识化数据集、数据字典、指标计算说明或统计分析代码,用于学术复核或合作研究。涉及可识别个人身份信息、运动队内部训练信息及未公开原始动捕数据的内容不对外共享。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
This study will not publicly share raw data containing personally identifiable information. After the main findings are published, de-identified datasets, data dictionaries, variable calculation procedures, or statistical analysis codes may be made available upon reasonable academic request and approval by the principal investigator, provided that informed consent, privacy protection requirements, and institutional data management regulations are not violated. Identifiable personal information, internal team training information, and unpublished raw motion-capture data will not be shared. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用纸质病例报告表和电子数据表进行数据采集与管理。采集内容包括受试者基本信息、训练背景、身高体重等身体形态指标、抗阻训练出勤率、训练负荷、组数、次数、主观用力感、不良事件记录,以及深蹲1RM、卧推1RM、10 m和20 m冲刺、CMJ、SJ、立定跳远、5-10-5变向、挥棒测速、三维动作捕捉、双力台和跳深测试等数据。 所有受试者均采用研究编号替代姓名,个人身份信息与研究数据分开保存。纸质资料由专人保管于上锁文件柜中,电子数据存放于加密电脑或授权存储空间,并设置访问权限和定期备份。数据录入后由至少两名研究人员进行核对,发现缺失值、异常值或无效试次时进行复核并记录原因。三维动捕、力台原始数据、处理脚本、导出指标表和统计分析文件均按受试者编号统一归档,确保数据处理过程可追溯。未经项目负责人授权,任何个人不得接触含有可识别身份信息的原始资料。以上内容与你方案中的数据管理制度保持一致 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data will be collected and managed using paper-based case report forms and electronic spreadsheets. The collected data will include participants’ demographic information, training background, height, body mass, resistance training attendance, training load, sets, repetitions, rating of perceived exertion, adverse events, as well as back squat 1RM, bench press 1RM, 10-m and 20-m sprint performance, countermovement jump, squat jump, standing long jump, 5-10-5 change-of-direction performance, swing speed, three-dimensional motion capture data, force plate data, and drop-jump testing data. Each participant will be assigned a unique study identification code instead of using their name. Personal identifying information will be stored separately from research data. Paper records will be kept in a locked cabinet by designated research personnel, while electronic data will be stored on password-protected computers or authorized storage platforms with restricted access and regular backup. After data entry, at least two researchers will check the data for accuracy. Missing values, outliers, or invalid trials will be reviewed and documented. Raw motion-capture data, force plate data, processing scripts, exported variables, and statistical analysis files will be archived according to participant identification codes to ensure traceability. No individual will be allowed to access identifiable raw data without authorization from the principal investigator. |
