The present study aimed to investigate the effects of traditional resistance training compared to elastic tubes training on bioimpedance vector patterns, body composition, and strength in older women. Thirty-eight older women (age 68.7 ± 6.9 years, body mass index 28.8 ± 7.2 kg/m²) were randomly assigned to perform traditional resistance or elastic tubes training three times per week for 12 weeks. Body composition was assessed by dual energy X-ray absorptiometry and bioelectrical impedance vector analysis. In addition, handgrip strength was measured using a dynamometer. Only the participants who followed the 12-week traditional resistance training program significantly (p < 0.05) decreased fat mass (ES: −0.69) and extracellular water (ES: −1.06), and increased total body water (ES: 0.49), intracellular water (ES: 1.11), body cell mass (ES: 0.82), muscle mass (ES: 0.94), and phase angle (ES: 0.99), while no change occurred in the elastic tubes training group. Furthermore, a vector leftward displacement (ES: 1.11) into the resistance-reactance graph was found only after the traditional resistance training program. The handgrip strength increased for both traditional and elastic tubes training groups (ES: 0.64, ES: 0.71, respectively). Traditional resistance training improved body composition and strength in the older women group, while training using elastic tubes was effective only for the latter. The present outcomes encourage the use of systematic resistance training to counteract the effects of aging in older women.

本研究旨在调查传统阻力训练与弹性管训练相比对老年女性生物阻抗矢量模式、身体成分和力量的影响。三十八名老年妇女（年龄 68.7 ± 6.9 岁，体重指数 28.8 ± 7.2 kg/m ²) 被随机分配进行传统的阻力或弹性管训练，每周 3 次，持续 12 周。通过双能 X 射线吸收测定法和生物电阻抗矢量分析评估身体成分。此外，使用测力计测量握力。只有遵循 12 周传统阻力训练计划的参与者显着（p < 0.05）减少了脂肪量（ES：-0.69）和细胞外水（ES：-1.06），并增加了全身水分（ES：0.49），细胞内水（ES：1.11）、体细胞质量（ES：0.82）、肌肉质量（ES：0.94）和相位角（ES：0.99），而弹性管训练组没有发生变化。此外，只有在传统的阻力训练计划之后才发现向阻力-电抗图中的向量向左位移（ES：1.11）。传统和弹性管训练组的握力均增加（分别为 ES：0.64、ES：0.71）。传统的阻力训练改善了老年女性的身体成分和力量，而使用弹性管的训练只对后者有效。目前的结果鼓励使用系统的阻力训练来抵消老年女性衰老的影响。
