To promote optimal neuromuscular and cardiovascular gains in older adults, it seems crucial to investigate the effects of different combined training volumes in this population. Thus, the present study aimed to compare the effects of combined muscle power training (MPT) and endurance training (ET) with different volumes on functional and hemodynamic parameters in previously trained older adults.
Twenty-five older adults were randomly assigned to either the lower-volume group (LVG; n = 13) or the higher-volume group (HVG; n = 12). In the LVG, participants performed 1 set of 6 repetitions for each exercise, followed by 10 min of walking exercise. In the HVG, participants performed 2 sets of 6 repetitions for each exercise, followed by 20 min of walking exercise. Lift from the ventral decubitus position (LPDV), timed up-and-go (TUG), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were assessed before and after 8 weeks.
Significant increases in LPDV test occurred in both groups after 8 weeks (p < 0.05). Additionally, significant improvements in TUG performance occurred in both groups from week 0 to week 8 (p < 0.05). However, no significant changes were observed between groups in functional parameters (p > 0.05). SBP and DBP remain unchanged (p > 0.05) in both groups over the experimental period.
These findings indicate that lower-volume and higher-volume of combined MPT and ET promoted improvements in functional parameters. This study has an important practical application, as it indicates that regardless of the volume (lower or higher), comparable improvements are observed in functional parameters in previously trained older adults.
为了促进老年人最佳的神经肌肉和心血管增益,似乎有必要研究该人群中不同组合训练量的影响。因此,本研究旨在比较低容量组(LVG;n=13)和高容量组(HVG;n=12)的肌肉力量训练(MPT)和耐力训练(ET)与不同容量对先前训练的老年人的功能和血液动力学参数的影响。
25 名老年人被随机分配到低容量组(LVG;n=13)或高容量组(HVG;n=12)。在 LVG 中,参与者对每个练习进行 1 组 6 次重复,然后进行 10 分钟的步行运动。在 HVG 中,参与者对每个练习进行 2 组 6 次重复,然后进行 20 分钟的步行运动。从仰卧位抬起(LPDV)、计时起立行走(TUG)、收缩压(SBP)和舒张压(DBP)在 8 周前后进行评估。
8 周后,两组的 LPDV 测试均显著增加(p<0.05)。此外,两组的 TUG 表现从第 0 周到第 8 周均有显著改善(p<0.05)。然而,功能参数组间无显著差异(p>0.05)。两组的 SBP 和 DBP 在整个实验期间保持不变(p>0.05)。
这些发现表明,低容量和高容量的组合 MPT 和 ET 均可促进功能参数的改善。本研究具有重要的实际应用价值,因为它表明,无论容量(低或高)如何,在先前训练的老年人中,功能参数都可以观察到类似的改善。
