Abstract
Walking in an irregular ground involves permanent adaptations that require: collecting information, its interpretation, and assembly of the appropriate strategies to perform the skill. With this study we aimed to understand what are the effects on heart rate (HR) when a person faces a situation where there is a constantly need to adapt. We’ve used a treadmill with several spots along the mat to constrain the person’s gait. Each of the 20 subjects performed two situations: walking on the treadmill for 10 minutes-(1) without any restriction; and 2) without stepping the spots. A HR monitor (POLAR) was used to measure HR during both situations. Results showed that between the two situations (1 and 2) there was an increase in HR mean of 44 bpm. Findings reinforce that the constant need for decision-making requires a cost that reflects on the individual HR.
