研究目的: |
本研究旨在考察8周乳清蛋白补充联合抗阻训练对健康男大学生重复运动能力、力量耐力及血液指标的影响,并与安慰剂对照组进行比较。 |

|
Objectives of Study: |
This study aimed to examine the effects of 8 weeks of whey protein supplementation combined with resistance training on repeated-sprint ability, strength endurance, and blood biomarkers in healthy male university students, and to compare these effects with those observed in a placebo control group. |
||||||||||||||||||||||
|
药物成份或治疗方案详述: |
本研究采用随机、双盲、安慰剂对照、平行分组实验设计。符合条件并签署知情同意书的受试者完成基线测试后,由独立研究人员按随机序列以1:1比例分配至乳清蛋白补充组或安慰剂对照组。两组均接受相同的8周抗阻训练干预。乳清蛋白和安慰剂采用统一编码和相似包装,受试者、训练监督人员和测试人员在研究结束前均不知晓分组信息。 |
||||||||||||||||||||||
|
Description for medicine or protocol of treatment in detail: |
This study adopted a randomized, double-blind, placebo-controlled, parallel-group experimental design. After completing baseline assessments, eligible participants who provided written informed consent were assigned by an independent researcher to either the whey protein supplementation group or the placebo control group in a 1:1 ratio according to a randomization sequence. Both groups underwent the same 8-week resistance training intervention. The whey protein and placebo were uniformly coded and packaged in a similar manner, and participants, training supervisors, and outcome assessors remained blinded to group allocation until the completion of the study. |

|
纳入标准: |
1. 18-25岁健康男大学生; 2. 无心血管、肺部、肝肾疾病及其他不适合参加抗阻训练的慢性疾病; 3. 近6个月内无影响训练和测试的严重运动损伤; 4. 能够按照研究要求参加8周训练、补剂摄入和测试; 5. 自愿参加本研究并签署知情同意书。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Healthy male university students aged 18–25 years; 2. No cardiovascular, pulmonary, hepatic, renal, or other chronic diseases that would make participation in resistance training unsuitable; 3. No severe sports-related injuries within the past 6 months that could affect training or testing; 4. Ability to participate in the 8-week training program, supplement intake, and testing procedures as required by the study; 5. Voluntary participation in the study and provision of written informed consent. |
||||||||||||||||||||||
|
排除标准: |
1. 对乳制品、乳清蛋白或安慰剂成分过敏,或存在明显乳糖不耐受且无法耐受相关补充; 2. 存在肝肾功能异常、代谢性疾病或其他研究者认为不适合参加本研究的情况; 3. 研究期间自行额外使用蛋白粉、肌酸、合成代谢类药物或其他可能影响肌肉增长的补剂; 4. 依从性差,训练出勤率或补剂摄入依从性不达标; 5. 测试或训练过程中出现损伤、明显不适或主动要求退出。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Allergy to dairy products, whey protein, or placebo ingredients, or obvious lactose intolerance that prevents tolerance of the relevant supplementation; 2. Abnormal liver or kidney function, metabolic diseases, or other conditions that the researchers consider unsuitable for participation in this study; 3. Additional self-administration of protein powder, creatine, anabolic agents, or other supplements that may affect muscle growth during the study period; 4. Poor compliance, including failure to meet the required training attendance rate or supplement intake adherence; 5. Occurrence of injury, marked discomfort, or voluntary withdrawal during testing or training. |

盲法: |
本研究采用双盲设计。乳清蛋白粉和安慰剂粉末由不参与训练指导、测试和数据分析的第三方研究人员按照随机编号进行统一编码、包装和发放准备。两种补剂在外观、颜色、口味、气味、包装形式和标识方式方面尽可能保持一致,以减少受试者和研究人员对分组情况的判断。 研究实施过程中,受试者、训练监督人员、测试人员及主要数据分析人员均不知晓受试者所属组别。补剂发放、训练监督和测试记录均以随机编号进行,不显示乳清蛋白补充组或安慰剂对照组等具体分组信息。随机编号与实际分组之间的对应关系由独立第三方研究人员单独保存,并在研究结束且完成主要统计分析前保持封存。 |

Blinding: |
This study used a double-blind design. The whey protein powder and placebo powder were uniformly coded, packaged, and prepared for distribution by a third-party researcher who was not involved in training supervision, outcome testing, or data analysis. The two supplements were made as similar as possible in appearance, color, taste, odor, packaging, and labeling to minimize the possibility that participants or researchers could identify group allocation. During the study, participants, training supervisors, outcome assessors, and the main data analysts were blinded to group allocation. Supplement distribution, training supervision, and outcome testing were conducted using randomization codes only, without displaying information indicating assignment to the whey protein supplementation group or the placebo control group. The correspondence between randomization codes and actual group allocation was kept solely by the independent third-party researcher and remained sealed until the completion of the study and the primary statistical analysis. |
