Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Fifteen normal-weight boys (aged 13-18y) were randomly assigned in a crossover design to four sessions: 1) Water + Rest; 2) Rest + ibuprofen; 3) Water + high intensity exercise; 4) high intensity exercise + ibuprofen. High intensity exercise consisted of three 10min bouts of high intensity exercise at 75% VO2peak at 60-70RPM with 1:30min active rest interposed. IBU was given in a 300mg liquid solution. EI, visual analog scale ratings and plasma biomarkers of appetite, inflammation, stress and glucose control were measured.
Primary purpose: BASIC_SCIENCE

Brief summary: This study investigates the effect of high intensity exercise, with and without the inflammation inhibitor, ibuprofen, on plasma levels of IL-6 and other selective biomarkers of inflammation and appetite on food intake and subjective ratings of appetite in normal-weight boys.
