This study investigated associations between variables of trunk muscle strength (TMS), spinal mobility, and balance in seniors. Thirty-four seniors (sex: 18 female, 16 male; age: 70 ± 4 years; activity level: 13 ± 7 hr/week) were tested for maximal isometric strength (MIS) of the trunk extensors, flexors, lateral flexors, rotators, spinal mobility, and steady-state, reactive, and proactive balance. Significant correlations were detected between all measures of TMS and static steady-state balance (r = .43-.57, p < .05). Significant correlations were observed between specific measures of TMS and dynamic steady-state balance (r = .42-.55, p < .05). No significant correlations were found between all variables of TMS and reactive/proactive balance and between all variables of spinal mobility and balance. Regression analyses revealed that TMS explains between 1-33% of total variance of the respective balance parameters. Findings indicate that TMS is related to measures of steady-state balance which may imply that TMS promoting exercises should be integrated in strength training for seniors.
本研究调查了老年人躯干肌肉力量（TMS）、脊柱活动度和平衡变量之间的关联。对34名老年人（性别：18名女性，16名男性；年龄：70±4岁；活动水平：13±7小时/周）进行了躯干伸肌、屈肌、侧屈肌、旋转肌的最大等长力量（MIS）、脊柱活动度以及静态、反应性和主动性平衡测试。在TMS的所有测量指标与静态稳态平衡之间检测到显著相关性（r = 0.43 - 0.57，p < 0.05）。在TMS的特定测量指标与动态稳态平衡之间观察到显著相关性（r = 0.42 - 0.55，p < 0.05）。在TMS的所有变量与反应性/主动性平衡之间以及脊柱活动度的所有变量与平衡之间未发现显著相关性。回归分析表明，TMS解释了各自平衡参数总方差的1%至33%。研究结果表明，TMS与稳态平衡测量指标相关，这可能意味着应将促进TMS的锻炼纳入老年人的力量训练中。
