Weight training is widely adopted and highly effective for enhancing both muscular strength and endurance. A popular weightlifting exercise is the deadlift, which targets multiple muscle groups including the lower back, glutes, and hamstrings. However, incorrect technique (i.e., poor form) can slow training progress, result in asymmetrical muscle development, and cause serious injuries. The objective of this study was to validate that a self-adhesive, elastic fabric, wearable, skin-strain sensor called Motion Tape (MT) could monitor a person's posture while performing deadlift exercises. Two pairs of Motion Tape were attached on the front and back sides of the pelvis at each posterior superior iliac spine to record muscle engagement during deadlift exercises. The results of this preliminary study confirmed that the MT identified asymmetry in muscle engagement during deadlifting repetitions. In addition, the sensors could quantify the different levels of effort exerted according to the deadlift weight load.
力量训练被广泛采用且对增强肌肉力量和耐力非常有效。一种流行的举重练习是硬拉，它针对多个肌肉群，包括下背部、臀大肌和腘绳肌。然而，不正确的技术（即姿势不佳）会减缓训练进度，导致肌肉发育不对称，并造成严重伤害。本研究的目的是验证一种名为运动胶带（MT）的自粘式、弹性织物、可穿戴的皮肤应变传感器能否在进行硬拉练习时监测人的姿势。在每个髂后上棘处，将两对运动胶带分别贴在骨盆的前后侧，以记录硬拉练习期间的肌肉参与情况。这项初步研究的结果证实，运动胶带能识别出硬拉重复动作过程中肌肉参与的不对称性。此外，这些传感器可以根据硬拉的重量负荷量化所施加的不同程度的力量。
