Resumo: | The difficulty involved in the calculation of the energy cost during most of the physical activities is related to the mixed nature of the energy elicited. Therefore, it is important to know under which exercise condition it is possible to perform such measurements and under which conditions it is not. Several terms are often associated with this line of research, such as: energy expenditure, caloric expenditure or energy cost. The aim of the current paper was to remind the methods that are typically used to assess energy cost and to propose a more precise nomenclature when teaching or researching under these thematic. The use of expired O2 to quantify aerobic energy seems undisputable. As to anaerobic lactic energy, more studies are required, using both the blood lactate energy equivalent and the accumulated oxygen deficit. The term “energy expenditure” should be used only when energy release is almost fully aerobic and when direct O2 measurement can be performed during exercise. In every other conditions of exercise, the term “energy cost” is more suitable, as it cannot be directly assessed. Whenever “energy cost” is referred, it should be accompanied by the identification of whether aerobic fraction, anaerobic fraction or total energy cost is considered. |

Energy expenditure, aerobic energy cost and anaerobic energy cost.Gasto energético, custo energético aeróbio e custo energético anaeróbioThe difficulty involved in the calculation of the energy cost during most of the physical activities is related to the mixed nature of the energy elicited. Therefore, it is important to know under which exercise condition it is possible to perform such measurements and under which conditions it is not. Several terms are often associated with this line of research, such as: energy expenditure, caloric expenditure or energy cost. The aim of the current paper was to remind the methods that are typically used to assess energy cost and to propose a more precise nomenclature when teaching or researching under these thematic. The use of expired O2 to quantify aerobic energy seems undisputable. As to anaerobic lactic energy, more studies are required, using both the blood lactate energy equivalent and the accumulated oxygen deficit. The term “energy expenditure” should be used only when energy release is almost fully aerobic and when direct O2 measurement can be performed during exercise.

Importa saber identificar em que condição é possível medir ou estimar o custo energético e em que condição tal não é possível. Existe uma utilização de diferentes termos associados a esta temática como, por exemplo, gasto energético, gasto calórico, dispêndio energético, ou custo energético. O objetivo deste artigo foi recordar os métodos mais populares de quantificação do custo energético e propor um maior rigor na nomenclatura a usar no ensino e investigação. Parece pacífica a utilização do O2 expirado como quantificador da energia aeróbia. Quanto à energia anaeróbia láctica, devem prosseguir estudos usando o défice de oxigénio acumulado ou o equivalente energético de lactato. O termo “gasto energético” deverá ser reservado a situações em que o exercício é quase exclusivamente aeróbio e em que é possível medir diretamente as trocas gasosas durante o esforço. Em todas as restantes situações, deverá ser usado preferencialmente o termo “custo energético”, porquanto o mesmo pode ser estimado, mas não medido diretamente. Quando usado o termo “custo energético” o mesmo deve ser complementado com a identificação se tratamos da fração aeróbia, da fração anaeróbia ou de ambas.Universidade Federal de Santa Catarina.
