The present study aimed to compare soleus, lateral, and medial gastrocnemius muscles activation during leg press and calf raise exercises in trained men. The study involved 22 trained men (27.1 ± 3.6 years, 82.7 ± 6.6 kg, 177.5 ± 5.2 cm, 3.6 ± 1.4 experience years) who performed one set of each exercise using a 10-repetition maximum (10RM) load in a counterbalanced randomized order and separated by 10 min of rest. The electromyographic signal was measured for the three major plantar flexors: soleus, medial, and lateral gastrocnemius. A comparison between exercises showed that the mean adjusted by peak values during the leg press were 49.20% for the gastrocnemius lateralis, 51.31% for the gastrocnemius medialis, and 50.76% for the soleus. Values for calf raise were 50.70%, 52.19%, and 51.34% for the lateral, medial gastrocnemius, and soleus, respectively. There were no significant differences between exercises for any muscle (lateral gastrocnemius ( = 0.230), medial gastrocnemius ( = 0.668), and soleus ( = 0.535)). The present findings suggest that both leg press and calf raises can be used with the purpose to recruit triceps surae muscles. This bring the suggestion that one can chose between exercises based on personal preferences and practical aspects, without any negative impact on muscle activation.
本研究旨在比较腿举和提踵练习中受训男性比目鱼肌、外侧和内侧腓肠肌的激活情况。研究涉及 22 名受过训练的男性（27.1 ± 3.6 岁，82.7 ± 6.6 公斤，177.5 ± 5.2 厘米，3.6 ± 1.4 年经验），他们以 10 次最大重复（10RM）的负荷在反序平衡随机顺序下完成每组练习各一次，中间间隔 10 分钟休息。三个主要跖屈肌（比目鱼肌、内侧和外侧腓肠肌）的肌电图信号被测量。练习之间的比较表明，腿举过程中通过峰值调整后的平均调整值为外侧腓肠肌 49.20%，内侧腓肠肌 51.31%，比目鱼肌 50.76%。提踵的数值分别为外侧腓肠肌 50.70%、内侧腓肠肌 52.19%和比目鱼肌 51.34%。对于任何肌肉（外侧腓肠肌（=0.230）、内侧腓肠肌（=0.668）和比目鱼肌（=0.535）），练习之间均无显著差异。本研究结果表明，腿举和提踵都可以用来募集小腿三头肌。这表明人们可以根据个人喜好和实际情况在练习之间进行选择，而不会对肌肉激活产生任何负面影响。
