Suspension training (ST) has been utilized over exercises performed on a stable surface to train multiple muscle groups simultaneously to increase muscle activation and joint stability.
HYPOTHESIS/PURPOSE: The purpose of this study was to determine whether ST augments muscle activation compared to similar exercises performed on a stable surface.
Cross-sectional study.
Twenty-five healthy adults (male: 16; women: 9; BMI: 23.50 ± 2.48 kg/m) had 16 pre-amplified wireless surface EMG electrodes placed bilaterally on: the pectoralis major (PM), middle deltoid (MD), serratus anterior (SA), obliques (OB), rectus abdominis (RA), gluteus maximus (GM), erector spinae (ES), and middle trapezius/rhomboids (MT). Each participant performed reference isometric exercises (Sorensen test, push-up, sit-up, and inverted row) to establish a baseline muscle contraction. Muscle activation was assessed during the following exercises: ST bridge, ST push-up, ST inverted row, ST plank, floor bridge, floor push-up, floor row, and floor plank. The root mean square (RMS) of each side for every muscle was averaged for data analysis. Multivariate analyses of variance (MANOVA) for each exercise with post-hoc comparisons were performed to compare muscle activation between each ST exercise and its stable surface counterpart.
MANOVAs for all exercise comparisons showed statistically significant greater muscle activation in at least one muscle group during the ST condition. Post-hoc analyses revealed a statistically significant increase in muscle activation for the following muscles during the plank: OB (p = 0.021); Push-up: PM (p = 0.002), RA (p<0.0001), OB (p = 0.019), MT (p<0.0001), and ES (p = 0.006); Row: MD (p = 0.016), RA (p = 0.059), and OB (p = 0.027); and Bridge: RA (p = 0.013) and ES (p<0.0001).
Performing ST exercises increases muscle activation of selected muscles when compared to exercises performed on a stable surface.

与在稳定表面上进行的运动相比，悬吊训练（ST）已被用于同时训练多个肌肉群，以增加肌肉激活和关节稳定性。
假设/目的：本研究的目的是确定与在稳定表面上进行的类似运动相比，ST是否能增强肌肉激活。
横断面研究。
25名健康成年人（男性16名；女性9名；体重指数：23.50±2.48kg/m²）双侧放置16个预放大的无线表面肌电图电极于：胸大肌（PM）、三角肌中束（MD）、前锯肌（SA）、斜肌（OB）、腹直肌（RA）、臀大肌（GM）、竖脊肌（ES）以及斜方肌中部/菱形肌（MT）。每位参与者进行参考等长运动（索伦森试验、俯卧撑、仰卧起坐和引体向上）以建立基线肌肉收缩。在以下运动过程中评估肌肉激活情况：ST桥、ST俯卧撑、ST引体向上、ST平板支撑、地面桥、地面俯卧撑、地面划船和地面平板支撑。对每块肌肉每侧的均方根（RMS）进行平均以进行数据分析。对每项运动进行多变量方差分析（MANOVA）并进行事后比较，以比较每种ST运动与其在稳定表面上对应运动之间的肌肉激活情况。
所有运动比较的MANOVA显示，在ST条件下，至少有一个肌肉群的肌肉激活在统计学上显著更高。事后分析显示，在平板支撑过程中以下肌肉的肌肉激活在统计学上显著增加：OB（p = 0.021）；俯卧撑：PM（p = 0.002）、RA（p<0.0001）、OB（p = 0.019）、MT（p<0.0001）和ES（p = 0.006）；划船：MD（p = 0.016）、RA（p = 0.059）和OB（p = 0.027）；以及桥：RA（p = 0.013）和ES（p<0.0001）。
与在稳定表面上进行的运动相比，进行ST运动可增加所选肌肉的肌肉激活。
