PROTEIN METABOLISM

This study looks at how eating different food combinations after resistance exercise affects muscle protein synthesis. Fifteen healthy, recreationally active adults will do leg exercises and then eat either potato with beef, bread with beef, or beef alone. Researchers will take b…

This study will use special 'tracer' molecules (stable isotopes) to measure how the body of an adult with obesity processes protein and sugar. Eight participants will each undergo two test sessions: one measuring protein breakdown and another measuring glucose tolerance. The goal…

This study looks at how healthy young adults process protein from whole foods like beef patties. Twenty people aged 18-35 will eat different amounts of protein (1, 2, or 4 patties) in a random order. Researchers measure how much protein the body uses over 24 hours. The goal is to…

This study tests whether a non-invasive breath test can accurately measure how the body builds muscle after eating protein, compared to the current gold-standard method that requires muscle biopsies. Eight healthy adults will drink protein shakes with special tracers, then provid…

This study looks at how natural menstrual cycles and oral contraceptive use affect muscle protein synthesis after resistance training. Twenty recreationally active women will consume protein drinks and undergo muscle biopsies to measure protein building. The goal is to understand…

This study looks at how well older adults (ages 65-95) with signs of frailty use protein from beef versus tofu to build muscle. Researchers will use a new technique to measure how the body processes these proteins. The goal is to understand which protein source might better suppo…

This study looks at how plant-based and whey (dairy) proteins affect muscle building in older adults, including those with muscle loss (sarcopenia). Researchers will measure how the body processes amino acids from each protein type. The goal is to learn which protein composition …

This study looks at how the body processes protein after a meal in adults aged 60 to 80. Researchers use special tracers to measure protein building and breakdown. The goal is to understand age-related changes in metabolism that may affect strength and health. No treatment is giv…
