The aim of the study is to evaluate the intensity of the effort and energy expenditure in the course of performing selected classical massage techniques and to assess the workload of a massage therapist during a work shift.
Thirteen massage therapists (age: 21.9±1.9 years old, body mass index: 24.5±2.8 kg×m, maximal oxygen consumption × body mass (VO×BM): 42.3±7 ml×kg×min) were involved in the study. The stress test consisted in performing selected classical massage techniques in the following order: stroking, kneading, shaking, beating, rubbing and direct vibration, during which the cardio-respiratory responses and the subjective rating of perceived exertion (RPE) were assessed. Intensity of exercise during each massage technique was expressed as % VO, % maximal heart rate (HR) and % heart rate reserve (HRR). During each massage technique, net energy expenditure (EE) and energy cost of work using metabolic equivalent of task (MET) were determined.
The intensity of exercise was 47.2±6.2% as expressed in terms of % VO, and 74.7±3.2% as expressed in terms of % HR, while it was 47.8±1.7% on average when expressed in terms of % HRR during the whole procedure. While performing the classical massage, the average EE and MET were 5.6±0.9 kcal×min and 5.6±0.2, respectively. The average RPE calculated for the entire procedure was 12.1±1.4. During the performance of a classical massage technique for a single treatment during the study, the average total EE was 176.5±29.6 kcal, resulting in an energy expenditure of 336.2±56.4 kcal×h. In the case of the classical massage technique, rubbing was the highest intensity exercise for the masseur who performed the massage (%VO = 57.4±13.1%, HR = 79.6±7.7%, HRR = 58.5±13.1%, MET = 6.7±1.1, EE = 7.1±1.4 kcal×min, RPE = 13.4±1.3).
In the objective assessment, physical exercise while performing a single classical massage is characterized by hard work. The technique of classical massage during which the masseur performs the highest exercise intensity is rubbing. According to the classification of work intensity based on energy expenditure, the masseur's work is considered heavy during the whole work shift. Int J Occup Med Environ Health 2018;31(5):677-684.
本研究旨在评估在执行选定的经典按摩技术过程中的努力强度和能量消耗，并评估按摩治疗师在一个工作班次中的工作量。
13名按摩治疗师（年龄：21.9±1.9岁，体重指数：24.5±2.8kg/m²，最大摄氧量×体重（VO₂×BM）：42.3±7ml·kg·min）参与了本研究。压力测试包括按以下顺序执行选定的经典按摩技术：轻抚、揉捏、抖动、拍打、摩擦和直接振动，在此期间评估心肺反应和主观用力感觉评分（RPE）。每种按摩技术期间的运动强度以%VO₂、%最大心率（HR）和%心率储备（HRR）表示。在每种按摩技术期间，测定净能量消耗（EE）和使用任务代谢当量（MET）的工作能量成本。
以%VO₂表示时，运动强度为47.2±6.2%，以%HR表示时为74.7±3.2%，而在整个过程中以%HRR表示时平均为47.8±1.7%。在进行经典按摩时，平均EE和MET分别为5.6±0.9kcal/min和5.6±0.2。整个过程计算的平均RPE为12.1±1.4。在研究期间单次治疗执行经典按摩技术时，平均总EE为176.5±29.6kcal，导致能量消耗为336.2±56.4kcal/h。对于经典按摩技术，摩擦是进行按摩的按摩师的最高强度运动（%VO₂ = 57.4±13.1%，HR = 79.6±7.7%，HRR = 58.5±13.1%，MET = 6.7±1.1，EE = 7.1±1.4kcal/min，RPE = 13.4±1.3）。
在客观评估中，进行单次经典按摩时的体育锻炼具有高强度的特点。按摩师进行最高运动强度的经典按摩技术是摩擦。根据基于能量消耗的工作强度分类，按摩师在整个工作班次中的工作被认为是繁重的。《国际职业医学与环境卫生杂志》2018年；31(5):677 - 684。
