Aging, cancer and its treatment all contribute to increase the risk of deconditioning and sedentary behaviors. Mixed exercise is recognized to counteract the effects of aging and deconditioning as well as improving physical capacity during cancer treatment in adults.
To determine the impact of a mixed exercise program (MXEP) to improve physical capacity and decrease sedentary behavior time (SBT) in older adults during cancer treatment.
Fourteen participants (68.8 ± 3.4 years) completed 12 weeks of a mixed exercise program (MEXP) (n = 6) or stretching (n = 8) while they were under cancer treatment. Five tests of the Senior Fitness Test (Chair Stand, 8-Foot Up & Go, Arm Curl, Sit & Reach, 6 min Walk Test), two maximal strength tests (leg press and handgrip) and a Global Physical Capacity Score (GPCS) were used to assess physical capacity. For the amount of SBT (min/day), we used question 1 of the Physical Activity Scale for the Elderly.
Both groups presented significant pre- vs post-intervention differences for the Chair Stand, Arm Curl, 6 min Walk Tests and also GPCS. Nevertheless, this difference was significantly greater in the MEXP group only for the Chair Stand Test (4.3 ± 2.2 vs 1.0 ± 1.3 reps; p = 0.01) and the GPCS (4.0 ± 0.6 vs 1.5 ± 2.3 points; p = 0.047). A tend to display a greater decrease in SBT (- 295 ± 241 min/week vs - 11 ± 290 min/week; p = 0.079) was observed in favor of MEXP.
A 12-week mixed exercise program led to significant improvements in physical capacity and may reduce SBT.
衰老、癌症及其治疗都会增加身体失能和久坐行为的风险。混合运动被认为可以对抗衰老和身体失能的影响，同时在癌症治疗期间提高成年人的身体能力。
确定混合运动方案（MXEP）对改善癌症治疗期间老年患者身体能力和减少久坐行为时间（SBT）的影响。
14 名参与者（68.8±3.4 岁）完成了 12 周的混合运动方案（MEXP）（n=6）或伸展运动（n=8），同时接受癌症治疗。使用五项老年人体能测试（椅子站立、8 英尺快走、手臂卷曲、坐立前伸、6 分钟步行测试）、两项最大力量测试（腿推和握力）和一项总体身体能力评分（GPCS）来评估身体能力。对于 SBT（分钟/天）的数量，我们使用老年人身体活动量表的第 1 题。
两组在椅子站立、手臂卷曲、6 分钟步行测试和 GPCS 方面均表现出干预前后的显著差异。然而，MEXP 组仅在椅子站立测试（4.3±2.2 与 1.0±1.3 次；p=0.01）和 GPCS（4.0±0.6 与 1.5±2.3 分；p=0.047）方面的差异更大。倾向于显示出更大的 SBT 减少（-295±241 分钟/周与-11±290 分钟/周；p=0.079），有利于 MEXP。
12 周的混合运动方案可显著提高身体能力，并可能减少 SBT。
