Abstract
Introduction: The Heart rate is an indicator that can be used to estimate oxygen consumption. It has been used to assess physical work load. However its use to assess the work that does not involve the whole body has not been sufficiently proved. Objective: To determine the relationship between oxygen consumption by body segments and heart rates. Methods: The relationship between heart rate, oxygen consumption and percentage of maximum oxygen consumption by ergospirometry and pulsometry in 30 individuals exposed to maximum loads executed with the whole body, legs and upper limbs was established. Results: Statistically significant differences between maximal oxygen consumption by gender and body segments were found. No significant differences between the proportion of oxygen consumption by genres was found. The relationship between heart rate and oxygen uptake by segment and by gender was linear with a correlation coefficient greater than 0.9. Conclusions: It’s possible to predict the arms and legs oxygen consumption and oxygen uptake from the heart rate values, the heart rate can be used as an estimate of the oxygen consumption by body segments.
