Because the lack of specialized textbooks, the select of basic exercises for physical conditioning programmes is based on empirical knowledge. This fact led the authors to propose the study on electromyographic activity of the trapezius (upper portion) (TS) and the serratus anterior (lower portion) (SI) muscles in rowing exercises with closed grip in three different modalities. The tests were carried out with 24 male volunteers, 18 to 25 years old, by using a two-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes. For exercises execution, a long bar made of light wood was used. TS acted significantly in the three different modalities, that is, upright, sitting and bent over, while SI acted preferentially in upright and sitting rowing exercises, justifying their inclusion as basic exercises in physical conditioning programmes.
由于缺乏专业教材,体能训练计划中基础练习的选择基于经验知识。这一事实促使作者对24名年龄在18至25岁之间的男性志愿者,在三种不同方式的闭握划船练习中斜方肌(上部)(TS)和前锯肌(下部)(SI)的肌电活动进行研究。测试使用双通道TECA TE 4肌电图仪和惠普表面电极进行。进行练习时,使用一根轻质木材制成的长杆。TS在三种不同方式(即直立、坐姿和俯身)下均有显著作用,而SI在直立和坐姿划船练习中作用更为明显,这证明将它们纳入体能训练计划的基础练习是合理的。
