The purpose of present study was to compare the tibialis anterior (TA), rectus femoris (RF), and erector spinae (ES) muscle activities at variety chair height during sit-to-stand (STS) on normal weight and obese subjects. Also, we compared the muscle activity difference between the normal weight and obese subjects. The study included 26 subjects (normal weight 13 and obese 13). Each subject performed STS at three chair heights (40 cm, 50 cm, 60 cm) and TA, RF, and ES muscle activities measured. According to the results of the measurement, muscle activation of TA showed significantly higher than RF and ES muscle activation during STS at all chair heights on obese subjects. The muscle activation of TA showed significantly higher than RF muscle activation during STS at all chair heights on normal weight subjects. The muscle activation of RF and ES showed significantly higher in normal weight subjects than obese subjects at 40 cm and 50 cm of chair heights. However, the TA muscle activation showed no significant difference between normal weight subjects and obese subjects. This study's results suggested that obese subjects should practice the use of RF and ES muscles in a low-height chair during STS.
本研究的目的是比较正常体重和肥胖受试者在不同椅子高度下从坐姿到站立（STS）过程中胫骨前肌（TA）、股直肌（RF）和竖脊肌（ES）的肌肉活动。此外，我们还比较了正常体重和肥胖受试者之间的肌肉活动差异。该研究包括26名受试者（正常体重13名，肥胖13名）。每位受试者在三种椅子高度（40厘米、50厘米、60厘米）下进行STS，并测量TA、RF和ES的肌肉活动。根据测量结果，在所有椅子高度下，肥胖受试者在STS过程中TA的肌肉激活显著高于RF和ES的肌肉激活。在所有椅子高度下，正常体重受试者在STS过程中TA的肌肉激活显著高于RF的肌肉激活。在椅子高度为40厘米和50厘米时，正常体重受试者的RF和ES的肌肉激活显著高于肥胖受试者。然而，正常体重受试者和肥胖受试者之间TA的肌肉激活没有显著差异。本研究结果表明，肥胖受试者在STS过程中应在低高度椅子上练习使用RF和ES肌肉。
