Balance ability is a necessary exercise factor required for the activities of daily living. This study investigated the effects of short-term complex exercise (CE) and core stability exercise (CSE) on balance ability and trunk and lower-extremity muscle activation on healthy male adults. Twenty-nine healthy male adults were included. All performed CE and CSE for 1 min each; the exercise order was randomized. The primary and secondary outcomes were balance ability and muscle activation, respectively. In balance ability, CE showed a significant difference in all variables in both eye-opened and eye-closed conditions compared with the baseline ( < 0.05). In comparisons among exercises, the path length and average velocity variables showed a significant decrease in the eye-opened condition, and the path length variable showed a significant decrease in the eye-closed condition ( < 0.05). In muscle activation, CE showed a significant increase in the gluteus medius (Gmed) and decrease in the rectus femoris (RF), tibialis anterior (TA), and RF/biceps femoris (BF) ratio in the eye-opened condition compared to the baseline and a significant decrease in RF and RF/BF ratio in the eye-closed condition ( < 0.05). Both CE and CSE improved the static balance ability. Furthermore, muscle activation significantly increases in Gmed and decreases in the RF, TA, and RF/BF ratio. Therefore, we recommend including CE in an exercise program that has the purpose of improving static balance ability.
平衡能力是日常生活活动所需的一项必要运动因素。本研究调查了短期复杂运动（CE）和核心稳定性运动（CSE）对健康成年男性平衡能力以及躯干和下肢肌肉激活的影响。纳入了29名健康成年男性。所有人均分别进行1分钟的CE和CSE；运动顺序随机。主要和次要结果分别为平衡能力和肌肉激活。在平衡能力方面，与基线相比，CE在睁眼和闭眼条件下的所有变量均显示出显著差异（<0.05）。在运动之间的比较中，睁眼条件下路径长度和平均速度变量显著降低，闭眼条件下路径长度变量显著降低（<0.05）。在肌肉激活方面，与基线相比，CE在睁眼条件下臀中肌（Gmed）显著增加，股直肌（RF）、胫骨前肌（TA）以及RF/股二头肌（BF）比值降低，在闭眼条件下RF和RF/BF比值显著降低（<0.05）。CE和CSE均改善了静态平衡能力。此外，Gmed的肌肉激活显著增加，RF、TA以及RF/BF比值降低。因此，我们建议在以改善静态平衡能力为目的的运动计划中纳入CE。
