研究目的:

本研究将针对基于速度的力量训练对网球运动员运动表现及激素反应影响的实验研究,同时将对照组设置为基于百分比的力量训练组,探究基于速度的力量训练间歇训练能否以较低的训练负荷提升运动员的运动表现及激素反应。  

Objectives of Study:

This study aims to investigate the effects of speed based strength training on the athletic performance and hormone response of tennis players. The control group will be set as the percentage based strength training group to explore whether interval training based on speed can improve athletes' athletic performance and hormone response with lower training load.

随机方法(请说明由何人用什么方法产生随机序列):

采用随机平行对照设计。通过计算机生成的随机数序列,将24名符合标准的受试者以1:1的比例完全随机分配至VBT组(n=12)或PBT组(n=12)。随机序列的产生由一名不参与后续招募与干预过程的独立研究人员完成,并采用按顺序编码、不透光的密封信封(或具有同等分配隐藏功能的电子系统)进行分配隐藏,以确保负责招募和评估的研究人员在分组前无法预知分配方案。

Randomization Procedure (please state who generates the random number sequence and by what method):

A randomized parallel-controlled design was adopted. Using a computer-generated random number sequence, 24 eligible subjects were allocated at a 1:1 ratio to either the VBT group (n = 12) or the PBT group (n = 12) by complete randomization. The random sequence was generated by an independent researcher not involved in subsequent participant recruitment or intervention procedures. Allocation concealment was ensured using sequentially numbered, opaque, sealed envelopes (or an electronic system with equivalent concealment function) to prevent researchers responsible for recruitment and assessment from foreseeing the assignment scheme prior to group allocation.

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:

数据采集: 所有数据均在为期8周的干预训练开始前(Pre-test)和结束后(Post-test)两个时间点进行采集,具体包括: 运动表现数据: 在标准化条件下,由经过培训的同一批研究人员使用统一仪器测量。测试指标包括深蹲1RM、10米冲刺用时、反向纵跳(CMJ)高度与峰值功率、立定跳远(SLJ)距离及网球发球速度。所有测试均重复三次,取最佳成绩记录。 血液生化指标: 于每日清晨安静状态下,由专业医护人员采集肘静脉血。样本送至合作实验室,采用标准化检测程序分析肌酸激酶(CK)、睾酮和皮质醇浓度。 数据管理: 记录与存储: 所有纸质原始数据由双人独立录入计算机,并采用电子表格(如Excel)进行存储与管理。为保护受试者隐私,所有数据均采用匿名化的唯一识别码(ID)进行标识。 质量控制: 对录入后的数据进行交叉核对与逻辑校验,以确保数据的准确性与完整性。对任何异常值或缺失值进行核实与标注。 数据保存: 最终的匿名化数据集由研究负责人妥善保存,并仅限研究团队成员在授权后访问,确保数据安全。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection: All data were collected at two time points: before (Pre-test) and after (Post-test) the 8-week intervention training period. The specific procedures were as follows: Athletic Performance Data: Measured under standardized conditions by the same team of trained researchers using uniform instruments. Test metrics included squat 1RM, 10-meter sprint time, countermovement jump (CMJ) height and peak power, standing long jump (SLJ) distance, and tennis serve velocity. All tests were performed three times, with the best result recorded. Blood Biochemical Parameters: Collected from the elbow vein by professional medical personnel under quiet morning conditions. Samples were sent to a collaborating laboratory, where creatine kinase (CK), testosterone, and cortisol concentrations were analyzed using standardized testing procedures. Data Management Recording and Storage: All raw paper-based data were independently entered into computers by two individuals and stored and managed using spreadsheets (e.g., Excel). To protect participant privacy, all data were labeled with anonymized unique identification codes (ID). Quality Control: Entered data were cross-checked and logically validated to ensure accuracy and completeness. Any outliers or missing values were verified and annotated. Data Preservation: The final anonymized dataset was securely maintained by the principal investigator and was accessible only to authorized research team members to ensure data security.
