研究设计:

随机平行对照 

Study design:

研究目的:

1.对比基于速度的力量训练(VBT)和基于百分比的力量训练(PBT)对网球运动员变向能力和快速力量的影响; 2.探讨VBT在更精确的训练调控下,能否通过减少疲劳和优化训练强度,更有效地提升网球运动员的力量表现和生理适应能力; 3.分析VBT和PBT对网球运动员血液生理指标的不同影响,揭示VBT在运动员身体恢复和训练负荷管理中的作用。  

Objectives of Study:

1.Compare the effects of velocity-based resistance training (VBRT) and percentage-based resistance training (PBRT) on change-of-direction ability and rapid strength in tennis players; 2.Explore whether VBRT, through more precise training regulation, can reduce fatigue and optimize training intensity to more effectively enhance tennis players' strength performance and physiological adaptation; 3.Analyze the differential effects of VBRT and PBRT on blood physiological indicators in tennis players, and reveal the role of VBRT in athlete recovery and training load management.

组别:

VBT组 (Velocity-Based Training Group)

样本量:

15

Group:

Velocity-Based Training Group

Sample size:

干预措施:

基于速度的力量训练(VBT):负荷速度曲线测试;按照预先设定的最大深蹲重量的百分比进行训练,在训练中每两至四周重新测试1RM;根据平均速度下降10%则停止该组训练。

干预措施代码:

Intervention:

Velocity-Based Training (VBT): Load-velocity profiling test; training at a percentage of pre-determined one-repetition maximum (1RM); retesting 1RM every two to four weeks during training; discontinuation of the training session when average velocity decreases by 10%.

Intervention code:

组别:

PBT组 (Percentage-Based Training Group)

Sample size:

干预措施:

基于百分比的力量训练(PBT):按照预先设定的最大深蹲重量的百分比进行训练;在训练中每两至四周重新测试1RM;第一周最后一次干预后30分钟内抽取血液样本。

干预措施代码:

Intervention:

Percentage-Based Training (PBT): training at a percentage of pre-determined one-repetition maximum (1RM); retesting 1RM every two to four weeks during training; blood sample collection within 30 minutes after the last intervention session in week one.

随机方法(请说明由何人用什么方法产生随机序列):

基线测试后进行随机分组,运用 SPSS 的随机数把参与者随机分配到两组:VBT 或 PBT。随机数字表顺序编码进行简单随机化分组

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

After the baseline test, random grouping was conducted. Participants were randomly assigned to two groups using the random numbers in SPSS: VBT or PBT. Simple randomization grouping is performed using sequential encoding in a random number table

盲法:

受试者和所有研究员均不能事先知道或决定干预对象将分配到哪一组接受治疗,也不能从已经进入的组别推测出下一个患者将分配到哪一组。分组后,参与者被专项教练口头告知她们的小组任务

Blinding:

Neither the subjects nor all the researchers could know or decide in advance which group the intervention subjects would be assigned to for treatment, nor could they infer from the groups they had already entered which group the next patient would be assigned to. After the groups were formed, the participants were orally informed of their group tasks by the specialized coaches
