Aerobic Training Suppresses Exercise-Induced Lipid Peroxidation and Inflammation in Overweight/Obese Adolescent Girls

This study aimed to determine whether aerobic training could reduce lipid peroxidation and inflammation at rest and after maximal exhaustive exercise in overweight/obese adolescent girls. Thirty-nine adolescent girls (14-19 years old) were classified as nonobese or overweight/obese and then randomly assigned to either the nontrained or trained group (12-week multivariate aerobic training program). Measurements at the beginning of the experiment and at 3 months consisted of body composition, aerobic fitness (VO2peak) and the following blood assays: pre- and postexercise lipid peroxidation (15F2a-isoprostanes [F2-Isop], lipid hydroperoxide [ROOH], oxidized LDL [ox-LDL]) and inflammation (myeloperoxidase [MPO]) markers. In the overweight/obese group, the training program significantly increased their fat-free mass (FFM) and decreased their percentage of fat mass (%FM) and hip circumference but did not modify their VO2peak. Conversely, in the nontrained overweight/obese group, weight and %FM increased, and VO2peak decreased, during the same period. Training also prevented exercise-induced lipid peroxidation and/or inflammation in overweight/obese girls (F2-Isop, ROOH, ox-LDL, MPO). In addition, in the trained overweight/obese group, exercise-induced changes in ROOH, ox-LDL and F2-Isop were correlated with improvements in anthropometric parameters (waist-to-hip ratio, %FM and FFM). In conclusion aerobic training increased tolerance to exercise-induced oxidative stress in overweight/obese adolescent girls partly as a result of improved body composition.

Postexercise Inflammasome Activation and IL-1β Production Mitigated by Flavonoid Supplementation in Cyclists

David C. Nieman, Francesca Ferrara, Alessandra Pecorelli, Brittany Woodby, Andrew T. Hoyle, Andrew Simonson, and Giuseppe Valacchi

Prolonged and intensive exercise induces transient inflammation, and this has traditionally been measured using a variety of biomarkers, including acute phase proteins, the neutrophil/lymphocyte ratio, and cytokine panels ( Nieman & Wentz, 2019 ; Nieman et al. 2019 ). Emerging evidence indicates

Increases in the inflammatory cytokine interleukin-6 (IL-6) are a key signal for hepcidin production ( Nemeth, Rivera et al., 2004 ), potentially representing an evolutionary response to inflammation, serving

The Efficacy of Tart Cherry Juice in Aiding Recovery After Intermittent Exercise

Rebecca Quinlan and Jessica A. Hill

studies have investigated the efficacy of TCJ following intermittent exercise, but these studies have yielded conflicting results. No benefits of TCJ on functional performance, markers of inflammation (interleukin 6, C-reactive protein [CRP]), or oxidative stress (uric acid) were demonstrated after water
