Most previous research on the correlates of physical activity has examined the aerobic or strength exercise guidelines separately. Such an approach does not allow an examination of the correlates of meeting the combined guidelines versus a single guideline, or one guideline versus the other. Here, we report the prevalence and correlates of meeting the combined and independent exercise guidelines in hematologic cancer survivors (HCS).
In a population-based, cross-sectional survey of 606 HCS from Alberta, Canada using a mailed questionnaire, we obtained separate assessments of aerobic and strength exercise behaviors, as well as separate assessments for motivations, regulations, and reflective processes using the multi-process action control framework (M-PAC).
Overall, 22% of HCS met the combined exercise guideline, 22% met aerobic-only, 10% met strength-only, and 46% met neither exercise guideline. HCS were more likely to meet the combined guideline over the aerobic-only guideline if they had no children living at home, and over both the aerobic and strength-only guidelines if they had completed university. As hypothesized, those meeting the combined guideline also had a more favorable strength-specific M-PAC profile (i.e., motivations, regulations, and reflective processes) than those meeting the aerobic-only guideline, and a more favorable aerobic-specific M-PAC profile than those meeting the strength-only guideline. Interestingly and unexpectedly, HCS meeting the combined guidelines also reported significantly greater aerobic-specific perceived control, planning, and obligation/regret than those meeting the aerobic-only guideline, and greater strength-specific perceived control, planning, and obligation/regret than those meeting the strength-only guideline.
Few HCS are meeting the combined exercise guidelines. M-PAC based variables are strong correlates of meeting the combined guidelines compared to aerobic or strength only guidelines. Strategies to help HCS meet the combined guidelines may need to promote more favorable behavioral regulations and reflective processes for both types of exercise rather than just the type of exercise in which HCS are deficient.
以往大多数关于身体活动相关因素的研究都是分别考察有氧运动或力量训练指南。这种方法无法检验达到综合指南与单一指南的相关因素，也无法比较一种指南与另一种指南。在此，我们报告血液系统癌症幸存者（HCS）达到综合和独立运动指南的患病率及相关因素。
在一项基于人群的横断面调查中，我们通过邮寄问卷对来自加拿大艾伯塔省的606名HCS进行了调查，分别获取了有氧运动和力量训练行为的评估，以及使用多过程行动控制框架（M-PAC）对动机、规则和反思过程的单独评估。
总体而言，22%的HCS达到了综合运动指南，22%仅达到有氧运动指南，10%仅达到力量训练指南，46%未达到任何运动指南。如果家中没有孩子居住，HCS达到综合指南的可能性高于仅达到有氧运动指南；如果完成了大学学业，HCS达到综合指南的可能性高于仅达到有氧运动指南和仅达到力量训练指南。如假设的那样，与仅达到有氧运动指南的人相比，达到综合指南的人在力量训练特定的M-PAC概况（即动机、规则和反思过程）方面更有利，与仅达到力量训练指南的人相比，在有氧运动特定的M-PAC概况方面更有利。有趣且出乎意料的是，与仅达到有氧运动指南的人相比，达到综合指南的HCS在有氧运动特定的感知控制、计划和义务/遗憾方面也显著更高，与仅达到力量训练指南的人相比，在力量训练特定的感知控制、计划和义务/遗憾方面也更高。
很少有HCS达到综合运动指南。与仅有氧运动或仅力量训练指南相比，基于M-PAC的变量与达到综合指南密切相关。帮助HCS达到综合指南的策略可能需要促进两种运动更有利的行为规则和反思过程，而不仅仅是HCS缺乏的那种运动类型。
