Abstract：
This study aimed to assess and compare changes in body composition, standing balance, cardiovascular parameters, and salivary biomarkers, particularly salivary antioxidant status, after brisk walking training with or without music in older women. Twenty-four subjects were randomly assigned to brisk walking groups: with music (BWM) (n=12) or without music (BW) (n=12). Eighteen subjects completed the exercise training (9 in each group), and their data were used for analysis. The research protocols were classified into three phases: pretraining phase, training phase, and posttraining phase, while the data collection was divided into four sessions: resting condition, during treadmill exercise testing, immediately posttreadmill exercise testing, and 5-min posttreadmill exercise testing defined as after the cool-down session. The results showed that 8 weeks of home-based brisk walking with or without music did not improve standing balance, blood pressure, salivary biomarkers including total protein concentration, and antioxidant status but maintained or prevented the decline of these parameters. Only the BWM group reduced fat mass relative to increasing fat-free mass (P<0.05) and improved recovery heart rate (P<0.05) by modifying cardiac autonomic control in posttreadmill exercise testing. Therefore, brisk walking with preferred music can be a tool to delay the progression of cardiovascular dysfunction in older women. A longer duration of the exercise program and larger groups of participants are needed for further investigation of brisk walking with or without music on physiological and biochemical changes.
摘要：
这项研究旨在评估和比较身体成分的变化，站立平衡，心血管参数,和唾液生物标志物，尤其是唾液抗氧化状态，在老年妇女进行有或没有音乐的快走训练后。24名受试者被随机分配到快走组：有音乐（BWM）（n=12）或没有音乐（BW）（n=12）。18名受试者完成了运动训练(每组9人),和他们的数据用于分析。研究方案分为三个阶段：训练前阶段，训练阶段,和训练后阶段，虽然数据收集分为四个阶段：休息状态，在跑步机运动测试中，立即在跑步机后进行运动测试，和5分钟的跑步机后运动测试定义为冷却期之后。结果显示，有或没有音乐的8周家庭快走并不能改善站立平衡，血压,唾液生物标志物，包括总蛋白质浓度，和抗氧化剂状态，但保持或阻止了这些参数的下降。仅BWM组通过在跑步机后运动测试中改变心脏自主神经控制，相对于增加无脂肪量降低了脂肪量（P<0.05），并改善了恢复心率（P<0.05）。因此,带着喜欢的音乐快走可以成为延缓老年女性心血管功能障碍进展的工具。需要更长的锻炼计划持续时间和更多的参与者才能进一步研究有或没有音乐的快步走的生理和生化变化。
