研究目的: |
本实验研究旨在通过6周的肌酸-甜菜根汁的联合补充能否有效的改善大学生排球运动员的身体成分和最大力量,以及相较于单一补剂的应用,联合补剂能否更有效的提升大学生排球运动员的训练效果和身体形态,并验证二者的协同效应,为训练策略提供证据。 |

|
Objectives of Study: |
This experimental study aims to investigate whether six weeks of combined creatine and beetroot juice supplementation can effectively improve body composition and maximum strength in college volleyball athletes. The study will also examine whether the combined supplementation can enhance training outcomes and body composition more effectively than either supplement alone, thereby verifying their synergistic effects and providing evidence for training strategies. |

随机方法(请说明由何人用什么方法产生随机序列): |
有两名实验以外的研究人员在前期基线测试后,使用SPSS软件对受试者进行随机分组。所有受试者被平均纳入到联合补剂组(甜菜根汁+肌酸)、肌酸组、甜菜根汁组与对照组中。受试者分组基于前测成绩与性别,以确保两组分配相等。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Two researchers outside the experiment randomly grouped the subjects using SPSS software after the baseline test in the early stage. All subjects were evenly included in the combined supplement group (beetroot juice + creatine), the creatine group, the beetroot juice group and the control group. The subjects were grouped based on their pre-test scores and gender to ensure an equal allocation between the two groups. |

盲法: |
本研究采用双盲设计。所有受试者及直接参与测试与训练的研究人员均不知晓受试者所属分组。为确保盲法的有效性,两名研究人员分别承担不同的任务:其中一名研究人员负责制作肌酸补剂、甜菜根汁、联合补剂及安慰剂;另一名研究人员则根据分组为受试者提供补剂并监督其按时摄入。通过该方法,受试者在整个实验过程中无法分辨所摄入的具体补剂类型,测试人员亦不知晓受试者分组信息,从而保证了实验的科学性与结果的客观性。 |
|
Blinding: |
This study employed a double-blind design. Neither the subjects nor the researchers directly involved in testing and training were aware of the subjects' group assignments. To ensure the integrity of the blinding, two researchers performed distinct roles: one researcher was responsible for preparing the creatine supplement, beetroot juice, combined supplement, and placebo; the other researcher administered the supplements to subjects according to their group assignments and monitored their timely intake. Through this method, subjects remained unaware of the specific supplement type they consumed throughout the experiment, while test administrators lacked knowledge of subject groupings. This approach guaranteed the scientific rigor and objective validity of the results. |
