Background

Nutrition guidance for athletes must consider a range of variables to effectively support individuals in meeting energy and nutrient needs. Resistance exercise is a widely adopted training method in athlete preparation and rehabilitation and therefore is one such variable that will influence nutrition guidance. Given its prominence, the capacity to meaningfully quantify resistance exercise energy expenditure will assist practitioners and researchers in providing nutrition guidance. However, the significant contribution of anaerobic metabolism makes quantifying energy expenditure of resistance exercise challenging.

Objective

The aim of this scoping review was to investigate the methods used to assess resistance exercise energy expenditure.

Methods

A literature search of Medline, SPORTDiscus, CINAHL and Web of Science identified studies that included an assessment of resistance exercise energy expenditure. Quality appraisal of included studies was performed using the Rosendal Scale.

Results

A total of 19,867 studies were identified, with 166 included after screening. Methods to assess energy expenditure included indirect calorimetry (n = 136), blood lactate analysis (n = 25), wearable monitors (n = 31) and metabolic equivalents (n = 4). Post-exercise energy expenditure was measured in 76 studies. The reported energy expenditure values varied widely between studies.

Conclusions

Indirect calorimetry is widely used to estimate energy expenditure. However, given its limitations in quantifying glycolytic contribution, indirect calorimetry during and immediately following exercise combined with measures of blood lactate are likely required to better quantify total energy expenditure. Due to the cumbersome equipment and technical expertise required, though, along with the physical restrictions the equipment places on participants performing particular resistance exercises, indirect calorimetry is likely impractical for use outside of the laboratory setting, where metabolic equivalents may be a more appropriate method.

评估抗阻运动能量消耗的方法：系统范围审查

 背景

运动员的营养指导必须考虑一系列变量，以有效支持个人满足能量和营养需求。抗阻运动是运动员准备和康复中广泛采用的训练方法，因此是影响营养指导的变量之一。鉴于其重要性，有意义地量化抗阻运动能量消耗的能力将有助于从业者和研究人员提供营养指导。然而，无氧代谢的显着贡献使得量化抗阻运动的能量消耗具有挑战性。

 客观的

本次范围审查的目的是调查用于评估抗阻运动能量消耗的方法。

 方法

对 Medline、SPORTDiscus、CINAHL 和 Web of Science 的文献检索发现了包括抗阻运动能量消耗评估在内的研究。使用罗森达尔量表对纳入的研究进行质量评估。

 结果

总共确定了 19,867 项研究，其中 166 项是经过筛选后纳入的。评估能量消耗的方法包括间接量热法 (n = 136)、血乳酸分析 (n = 25)、可穿戴监测器 (n = 31) 和代谢当量 (n = 4)。 76 项研究测量了运动后的能量消耗。不同研究报告的能量消耗值差异很大。

 结论

间接量热法广泛用于估计能量消耗。然而，鉴于其在量化糖酵解贡献方面的局限性，可能需要在运动期间和运动后立即进行间接热量测定并结合血乳酸测量，以更好地量化总能量消耗。然而，由于所需的笨重设备和技术专业知识，以及设备对进行特定阻力练习的参与者的身体限制，间接量热法在实验室环境之外使用可能不切实际，在实验室环境之外，代谢当量可能是更合适的方法。
