Abstract
The influence of gender on the glucose response to exercise remains contradictory Moreover to our knowledge the glucoregulatory responses to anaerobic sprint exercise have only been studied in male subjects Hence the aim of the present study was to compare glucoregulatory metabolic glucose and lactate and hormonal insulin catecholamines and estradiol only in women responses to a 30s Wingate test in physically active students Eight women 198 07 years and eight men 220 06 years participated in a 30s Wingate test on a bicycle ergometer Plasma glucose insulin and catecholamine concentrations were determined at rest at the end of both the warmup and the exercise period and during the recovery 5 10 20 and 30 min Results showed that the plasma glucose increase in response to a 30s Wingate test was significantly higher in women than in men 099 015 versus 033 020 mmol l−1 respectively P005 Plasma insulin concentrations peaked at 10 min postexercise and the increase between this time of recovery and the end of the warmup was also significantly higher in women than in men 147 29 versus 23 19 pmol l−1 respectively P005 However there was no gender difference concerning the catecholamine response The study indicates a genderrelated difference in postexercise plasma glucose and insulin responses after a supramaximal exerciseThe authors thank nurses Dominique Paul and MarieThérèse Gougeon and laboratory technician Yolande Briand for technical assistance thank Kathy Stephen and Michelle Jester for English language correction and thank all the volunteers for their participation in this study The experiments used in this article complied with the current laws of France
