Abstract
Prolonged sitting can impair postprandial glycemia, lipidemia, and insulin sensitivity regardless of previous health status. We demonstrate that interrupting prolonged sitting with brief periods of activity, such as body weight squats or short bouts of walking, improves the efficiency of dietary amino acid utilizations for muscle contractile protein synthesis. This further emphasizes the importance of minimizing sedentary time to improve the postprandial metabolism of all macronutrients.
