The acute and postprandial effects of sugar moiety on vascular and metabolic health outcomes in adolescents.

This study explored the cardiometabolic responses to sugar moieties acutely, and following a subsequent mixed meal tolerance test (MMTT). Twenty-one healthy adolescents ( = 10 female, 14.3 ± 0.

The reliability of a breath-hold protocol to determine cerebrovascular reactivity in adolescents.

Purpose: Cerebrovascular reactivity (CVR) is impaired in adolescents with cardiovascular disease risk factors. A breath-hold test is a noninvasive method of assessing CVR, yet there are no reliability data of this outcome in youth. This study aimed to assess the reliability of a breath-hold protocol to measure CVR in adolescents.

Contralateral fatigue during severe-intensity single-leg exercise: influence of acute acetaminophen ingestion.

Exhaustive single-leg exercise has been suggested to reduce time to task failure (T) during subsequent exercise in the contralateral leg by exacerbating central fatigue development. We investigated the influence of acetaminophen (ACT), an analgesic that may blunt central fatigue development, on T during single-leg exercise completed with and without prior fatiguing exercise of the contralateral leg. Fourteen recreationally active men performed single-leg severe-intensity knee-extensor exercise to T on the left (Leg) and right (Leg) legs without prior contralateral fatigue and on Leg immediately following Leg (Leg).
