研究目的: |
本研究旨在评估支链氨基酸(BCAAs)补充剂对大学生篮球运动员在模拟比赛期间的力发展率(RFD,肌肉爆发力指标)的影响。通过随机对照交叉双盲试验设计,我们探究BCAAs补充对不同时间间隔内的RFD的作用,特别是在50毫秒时间窗口内,这是爆炸性力量表现的关键时期。 |

|
Objectives of Study: |
The primary objective of this study is to evaluate the impact of branched-chain amino acids (BCAAs) supplementation on the rate of force development (RFD) in collegiate basketball players during simulated game conditions. Through a randomized, controlled, crossover, double-blind trial design, we aim to explore the effects of BCAA supplementation on RFD at various time intervals, with a particular focus on the 50ms time window, a critical period for explosive power performance. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究中通过计算机生成的随机数序列来实施,以确保每位参与者都有同等机会被分配到BCAAs组或安慰剂组。具体而言,独立的研究人员将使用SPSS软件(IBM SPSS Statistics 23.0)的随机数生成器来创建一个1:1比率的随机代码列表。这些代码将决定参与者被分配到哪个组别,确保整个过程的随机性和公平性。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
In this study, implementation will be through a computer-generated sequence of random numbers to ensure that each participant has an equal chance of being assigned to either the BCAAs group or the placebo group. Specifically, independent researchers will utilize the random number generator feature in SPSS software (IBM SPSS Statistics 23.0) to create a list of random codes at a 1:1 ratio. These codes will determine which group participants are allocated to, ensuring randomness and fairness throughout the process. |

盲法: |
以下是实施盲法的具体方法和过程: 1. 相似包装和编码:BCAAs和安慰剂均被包装成外观完全相同的形式,且都带有随机分配的编码,使得无论是参与者还是执行实验的研究人员都无法通过视觉辨认出两者的区别。 2. 独立的编码和分发:编码和分发工作由未直接参与研究的独立第三方执行,他们根据预设的随机化方案进行分配,确保研究团队成员和参与者在实验开始前不知道具体的分配情况。 3. 标准训练和指导:在实验开始之前,所有参与者都接受了标准化的训练和指导,以确保他们能够正确地按照要求执行测试,同时,在整个实验过程中,参与者被明确告知不要试图猜测自己所接受的是BCAAs还是安慰剂,以保持盲法的有效性。 4. 结局评估者的盲态:所有结局评估者在收集和分析数据时都不知道参与者所属的组别,这包括力量和跳跃测试的结果、敏捷性和短跑测试的成绩以及生理反应的监测,确保了评估的公正性。 5. 保密协议:所有涉及研究的人员都被要求签署保密协议,承诺在整个研究期间及之后的一段时间内,不会泄露有关参与者分组的信息,直到研究结束并公布结果。 |
|
Blinding: |
Here are the specific methods and procedures for implementing blinding in the study: 1. Similar Packaging and Coding: Both the BCAAs and the placebo are packaged in forms that look exactly alike, with both bearing randomly assigned codes. This ensures that neither the participants nor the researchers conducting the experiment can visually distinguish between the two substances. 2. Independent Coding and Distribution: The coding and distribution tasks are carried out by an independent third party who is not directly involved in the research. They allocate the substances according to a pre-established randomization scheme, ensuring that members of the research team and participants do not know the specific allocations before the start of the experiment. 3. Standard Training and Instructions: Prior to the commencement of the experiment, all participants receive standardized training and instructions to ensure they can perform the required tests correctly. Additionally, throughout the course of the experiment, participants are explicitly instructed not to attempt to guess whether they are receiving BCAAs or a placebo, maintaining the effectiveness of the blinding. 4. Blind Outcome Assessors: All outcome assessors remain unaware of the participants' group assignments when collecting and analyzing data. This includes results from strength and jump tests, agility and sprint test scores, as well as monitoring physiological responses, ensuring impartiality in the assessments. 5. Confidentiality Agreements: All personnel involved in the research are required to sign confidentiality agreements, committing to not disclose information about the participants' group assignments during the entire study period and for a certain time thereafter, until the study concludes and the results are published. |
