随机方法(请说明由何人用什么方法产生随机序列):

对受试者进行1~42编号,通过分层随机化分组按照性别分为1个分层因素,由计算机在每层进行随机分组最后合并分为3组,每组14人,其他研究人员均不知情。A组为BFR大腿组(BFRT-t),B组为BFR小腿组(BFRT-c),C组为高负荷对照组(HL)。将填写有组别的卡片依次放入编号的不透明的密闭信封之中。待干预开始时,将对应受试者的信封交于治疗师,治疗师并不了解本实验设计,只按照规定的治疗方案进行8周干预。

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

Subjects were numbered from 1 to 42, grouped by stratified randomisation into 1 stratification factor according to sex, and randomised by computer at each stratum into 3 groups of 14 each, each group without the knowledge of the other researchers.Group A was the BFR thigh group (BFRT-t), group B was the BFR calf group (BFRT-c), and group C was the high load control group (HL). The cards with the groups filled in were placed sequentially into numbered, opaque, closed envelopes. When the intervention started, the envelope corresponding to the subject was handed over to the therapist, who was not aware of the experimental design and only followed the prescribed treatment protocol for the 8-week intervention.

盲法:

所有受试者对于不同干预条件的实际意义保持盲目,操作人员并不了解本实验设计,只按照规定的方案进行干预。不同受试者在不同时间段接受训练,偶然遇到不能互相讨论各自的干预方案。

Blinding:

All subjects remained blind to the practical significance of different intervention conditions. The operators were unaware of the experimental design and only carried out interventions according to the prescribed protocol. Different subjects received training at different time periods and happened not to be able to discuss their respective intervention plans with each other.
