Why the study?
Does a heart rate index correcting for smoking and cardiorespiratory fitness improve the estimation of exercise intensity during occupational activity compared to heart rate alone?
Does a heart rate index correcting for smoking and cardiorespiratory fitness improve the estimation of exercise intensity during occupational activity compared to heart rate alone?
A heart rate index that corrects for smoking and cardiorespiratory fitness may provide a more accurate estimation of occupational physical activity intensity than heart rate alone.
Answers are grounded in this paper and cite their sources.
May aid occupational activity assessment in select patients; leaves open prospective validation before broader adoption.
Objectives: Recording devices relying solely on heart rate (HR) are not considered accurate enough for measurement of energy expenditure of occupational physical activity (OPA) and leisure time physical activity (LTPA), due to factors which modulate the heart rate-oxygen uptake relationship such as smoking and cardiorespiratory fitness. This study used HR index which corrects for the effect of smoking and cardiorespiratory fitness on HR, to estimate the exercise intensity of occupational activity and determine whether smoking and exercise habits influenced work performance.
