摘要

背景:功能性训练(FT)已广受欢迎,似乎对健康有益。然而,关于能量消耗(EE)与体重减轻以及心肺功能改善之间的关系,有一些未经证实的说法。研究目的本研究量化了在传统健身中心进行 FT 时的能量消耗和强度。此外,还对 FT 和中度持续步行(WLK)的数据进行了比较。方法:没有进行过徒步运动的健康人[n = 25,11 男/14 女,38.8 ± 9.3 岁;73.9 ± 13.8 千克;168.5 ± 8.5 厘米;26.0 ± 4.5 千克/平方米;16 超重(体重指数大于 25 千克/平方米)]在 48 小时内进行了三次徒步运动(两次熟悉,一次评估)。循环训练包括 4 轮 12 个练习,每轮以全力以赴的强度进行 20 秒,每轮之间间隔 1 分钟。WLK持续25分钟,强度与博格CR-10量表中的3-5分相对应。结果包括 EE(千卡)、三轴加速度计估算的运动次数、心率储备(%HRR)和体力消耗率(RPE)。结果:体能训练平均持续 24 分钟,EE 在 124 至 292 千卡(188 ± 41 千卡)之间,相当于 5-8 METs(6.1 ± 0.6 METs)和 70-80%HRR (74 ± 8%)。加速度计(计数/分钟)显示,在 FT 和 WLK 期间,剧烈强度比中等强度占优势(p = .01),EE 相似。FT 与 WLK 相比,相对强度和 RPE 更高(分别为 74% 与 55%HRR 和 Borg 5-8 与 3-5;p < .0001)。结论FT 和 WLK 引发的 EE 符合降低心血管疾病风险的建议,但只有 FT 达到了与心肺功能改善相匹配的相对强度。在面向普通人群的健康锻炼计划中,应将 FT 作为一种选择。

Energy Expenditure, Intensity, and Perceived Effort in Recreational Functional Training.

Background: Functional training (FT) has become popular and seems to provoke health benefits. However, there are unsubstantiated claims regarding energy expenditure (EE) vs. weight-loss and cardiorespiratory improvements linked to FT. Objective: This study quantified the EE and intensity during FT performed in a conventional fitness center. Additionally, data of FT and moderate continuous walking (WLK) were compared. Methods: Healthy individuals with no previous experience with FT [n = 25, 11 males/14 females, 38.8 ± 9.3 years; 73.9 ± 13.8 Kg; 168.5 ± 8.5 cm; 26.0 ± 4.5 Kg/m2; 16 overweight (BMI >25 Kg/m2)] performed three FT sessions interspersed with 48 h (two familiarization, one assessment). The circuit included 4 rounds of 12 exercises performed at all-out intensity for 20 s with 1-min intervals between rounds. WLK was performed for 25 min with intensity corresponding to scores 3-5 on Borg CR-10 Scale. Outcomes were EE (kcal), movement counts estimated by triaxial accelerometry, heart rate reserve (%HRR), and rate of perceived exertion (RPE). Results: On average, FT sessions lasted 24 min and EE ranged between 124 and 292 kcal (188 ± 41 kcal), corresponding to 5-8 METs (6.1 ± 0.6 METs), and 70-80%HRR (74 ± 8%). Accelerometry (counts/min) showed that vigorous predominated over moderate intensity during FT and WLK (p = .01), with similar EE. The relative intensity and RPE were higher in FT vs. WLK (74% vs. 55%HRR and Borg 5-8 vs. 3-5, respectively; p < .0001). Conclusion: FT and WLK elicited EE consistent with recommendations to reduce cardiovascular disease risk, but only FT achieved relative intensities compatible with cardiorespiratory improvement. FT should be considered an option in health-oriented exercise programs for the general population.

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
