Nine male physical active subjects, (age 21.89 ± 2.52 years old, height 175.89 ± 5.16 cm, weight 72.10 ± 4.31 kg, estimated body fat 7.25 ± 2.11%), randomly performed two sessions of 45 minutes' low intensity exercise (individual ventilator threshold) interspersed by seven days, differentiated only in whether they were provided with a standardized meal or not. The oxygen consumption (VO2) and heart rate (HR) were measured continuously at the 30-min rest, the 45-min during and the 30-min post-exercise. The testosterone (T) and cortisol (C) hormones were measured atPloS oneCardiorespiratory, enzymatic and hormonal responses during and after walking while fasting.PMC5833199UID/DTP/04045/2013Rosa CLund RMatos FGarrido NMuller FSaavedra FJVilaca-Alves JMachado Reis VPayan-Carreira RfalseCardiorespiratory, enzymatic and hormonal responses during and after walking while fasting.The aim of the present study was to observe whether performing a low intensity endurance exercise following an overnight fasted (FAST) or fed (FED) condition promotes different cardiorespiratory, enzymatic and hormonal responses.
