摘要
本研究旨在比较不同三角肌运动中握力和活动度(ROM)变化对肌肉活动的影响。14名接受阻力训练的男性自愿接受1RM和肌电图测试,其负荷相当于80%的1RM。受试者在哑铃前举(DFR)中进行了三种不同的握法,在哑铃侧举(DLR)中进行了两种不同的ROM变化,在哑铃后举(DRDR)中进行了两种不同的握法。肌电图(EMG)活动在三角肌前,内侧和后头测量。DFR运动中,前三角肌肌电活动最高,前三角肌肌电活动最高,前三角肌肌电活动最高(51.57%)。对于前三角肌肌电活动,PG组(51.57%)明显高于锤握组(43.36%)(p小于0.05)。后三角肌HG ecc活性(40.36%)显著高于PG ecc活性(36.4%)(p小于0.05)。在DLR训练中,内侧三角肌和有限ROM (LTR)的活动最高(20.74%)。前头LTR con(19.37%)明显大于全ROM con (16.88%) (p小于0.05)。DRDR运动中,内侧三角肌的平均活动较大,HG的活动最高(24.47%)。标准握力(STD) ecc组的后三角肌平均肌电活动明显高于HG ecc组(17.3%)(p小于0.05)。总之,对于三角肌头,使用不同的握法和活动度变化可能会增加神经肌肉活动。
THE EFFECTS OF HANDGRIP AND RANGE OF MOTION VARIATIONS ON MUSCLE ACTIVITY IN DIFFERENT DELTOID EXERCISES
This study aimed to compare the effects of handgrip and range of motion (ROM) variations on muscle activity in different deltoid exercises. 14 resistance-trained men volunteered for 1RM and EMG testing with a load corresponding to 80% of 1RM. The subjects performed three different handgrips during Dumbell Front Raise (DFR), two different ROM variations for Dumbell Lateral Raise (DLR), and two different handgrips during Dumbell Rear Delt Raise (DRDR). Electromyogram (EMG) activity was measured in the anterior, medial, and posterior heads of deltoids. For the DFR exercise, the highest mean EMG activity was greater for the anterior deltoid, and the highest activity was observed in pronate grip (PG) con (51.57%). For the anterior deltoid EMG activity was significantly greater in PG con (51.57%) compared with hammer grip (HG) con (43.36%) (p˂0.05). HG ecc activity (40.36%) was significantly greater than PG ecc (36.4%) in posterior deltoid (p˂0.05). For the DLR exercise, the highest activity was observed in medial deltoid, and for limited ROM (LTR) (20.74%). LTR con activity (19.37%) was significantly greater than full ROM con (FLR) (16.88%) in the anterior head (p˂0.05). For the DRDR exercise, the mean activity was greater in medial deltoid, and HG con showed the highest activity (24.47%). The mean electromyography activity for the posterior deltoid was significantly greater in standard grip (STD) ecc compared with HG ecc (17.3%) (p˂0.05). In conclusion, for the heads of the deltoid muscle, the use of the different handgrip and ROM variations may increase neuromuscular activity.
