Core musculature is important for efficiency during activities including running. Both abdominal muscle strength and endurance contribute to this efficiency. The purpose of this study is to determine what differences and relationships exist in abdominal muscle thickness, strength, and endurance among persons who are runners, active, and inactive.
Persons in the running group would show significantly greater abdominal muscle thickness, muscle strength, and muscle endurance compared with those in the nonrunning groups.
Quantitative cohort design.
Level 2b.
A total of 78 subjects aged 18 to 27 years were divided into 3 groups: runners, active, and inactive. Assessment included abdominal muscle thickness via diagnostic ultrasound (Mindray North America), strength using a static Isotrack dynamometer (JTech Medical), and abdominal muscle endurance using a side plank. Statistical analysis using analysis of variance, tests, and Pearson's correlation coefficients and partial correlations was performed using SPSS Version 26 with a significance level of < 0.05.
Significantly greater muscle thickness of internal obliques (IOs) at rest and during contraction was found in the running group compared with the active group, the active group compared with the inactive group, and the running group compared with the inactive group. There were no statistically significant differences in overall strength measured by dynamometry among the 3 groups. Plank time was significantly greater for the running group compared with the other 2 groups. Male participants were greater in all areas: strength, plank time as a measure of muscle endurance, and muscle thickness. Body mass index was significantly correlated with resting thickness, muscle endurance, and muscle strength.
Persons who run, are active, and are inactive use their abdominal muscles differently. Runners have thicker IOs and better abdominal muscle endurance than the other 2 groups. Focusing on endurance training of the obliques may be beneficial for persons who run.
This research could contribute to developing core training programs to ensure runners target the correct abdominal muscles with the best type of training.
核心肌群对于跑步等活动的效率很重要。腹部肌肉的力量和耐力都有助于提高效率。本研究旨在确定跑步者、活跃者和不活跃者的腹部肌肉厚度、力量和耐力有何差异和关系。
与非跑步组相比，跑步组的腹部肌肉厚度、肌肉力量和肌肉耐力显著更大。
定量队列设计。
2b 级。
共有 78 名年龄在 18 至 27 岁的受试者分为 3 组：跑步者、活跃者和不活跃者。评估包括使用 Mindray North America 诊断超声仪测量腹部肌肉厚度、使用 JTech Medical 静态 Isotrack 测力计测量肌肉力量以及使用侧板测量腹部肌肉耐力。使用 SPSS 版本 26 进行方差分析、t 检验和 Pearson 相关系数和偏相关分析，显著性水平为 < 0.05。
与活跃组相比，跑步组在休息和收缩时的内斜肌（IO）肌肉厚度明显更大，与不活跃组相比，跑步组在休息和收缩时的 IO 肌肉厚度明显更大，与不活跃组相比，跑步组在休息和收缩时的 IO 肌肉厚度明显更大。3 组之间通过测力计测量的整体力量没有统计学上的显著差异。与其他 2 组相比，跑步组的侧板时间明显更长。男性参与者在所有方面都更大：力量、作为肌肉耐力衡量标准的侧板时间和肌肉厚度。体重指数与静息厚度、肌肉耐力和肌肉力量显著相关。
跑步者、活跃者和不活跃者对腹部肌肉的使用方式不同。跑步者的 IO 更厚，腹部肌肉耐力比其他 2 组更好。针对跑步者进行针对侧肌的耐力训练可能会有所帮助。
这项研究可以为制定核心训练计划做出贡献，以确保跑步者使用最佳类型的训练来针对正确的腹部肌肉。
