The purpose of this study was to analyze the effect of prolonged sitting time on cardiometabolic markers in physically active and inactive adults. Ten physically active adults (27.30 ± 4.90 years old) and 11 physically inactive (26.27 ± 3.17 years old) participated in the study. All performed a 10-hour long sitting session, with a total of four standardized meals. Glucose and blood pressure levels were measured at fasting, before and 1 hour after each meal, and 2 hours after lunch. Triglycerides levels were measured on fasting at 2 and 3.5 hours after lunch. The generalized linear model was used to compare the area under the incremental curve (AUCi) of the glucose and triglycerides levels, and the area under the curve (AUC) of the blood pressure levels between the groups, adjusted for baseline values. The physically active group showed lower blood glucose AUCi of 10 hours (β = -5.55 mg/dL/10h; 95%CI: -9.75; -1.33, p = 0.010), and morning (β = -7.05 mg/dL/5h; 95%CI: -12.11; -1.99, p = 0.006) compared to the physically inactive group. There was no difference in triglycerides AUCi (p = 0.517) and blood pressure AUC (p = 0.145) between groups. In conclusion, physically active adults have better glycemic control than physically inactive adults during exposure to prolonged sitting time.
