LynchD_Data_9-21

This data set represent the kinematic and RMS-EMG data produced during a study that investigated the effects of trunk stabilization on lower quarter neuromuscular control during a loaded barbell squat. Twenty-eight healthy male subjects (mean age 22.1±1.9 years) performed 3 squat-repetitions at 75% of predicted one-rep-max load using 4 trunk stabilization conditions: no bracing/belt (NoSS), abdominal bracing (AB), stabilization belt (StB), and AB+StB. Subjects first performed NoSS and the remaining conditions were randomized. Lower quarter surface electromyography and 3-D kinematic variables were obtained. A single-factor ANOVA assessed trunk kinematic data. A 2(phase)x4(strategy/side) ANOVA assessed all other variables.本数据集收录了一项探究负重杠铃深蹲过程中躯干稳定策略对下肢神经肌肉控制影响的研究所得的运动学与均方根肌电（RMS-EMG）数据。该研究共纳入28名健康男性受试者，平均年龄为22.1±1.9岁。每名受试者在4种躯干稳定条件下完成3次深蹲动作，负重为其预估单次最大负重的75%，4种条件分别为：无支撑无腰带（NoSS）、腹部收紧支撑（AB）、稳定腰带（StB）以及腹部收紧支撑联合稳定腰带（AB+StB）。受试者首先完成无支撑无腰带组的测试，其余三种条件的测试顺序采用随机化设计。研究采集了下肢表面肌电信号与三维运动学变量，其中采用单因素方差分析（ANOVA）对躯干运动学数据进行统计分析，采用2（阶段）×4（策略/侧别）的方差分析对其余变量开展统计分析。
