Effect of Reducing Sedentary Behavior on Blood Pressure (RESET BP): Rationale, design, and methods.

Contemp Clin Trials 2021 May 7:106428. Epub 2021 May 7.

Department of Health and Human Development, University of Pittsburgh, Pittsburgh, PA, United States of America.

Sedentary behavior (SB) has recently been recognized as a strong risk factor for cardiovascular disease, with new guidelines encouraging adults to 'sit less, move more.' Yet, there are few randomized trials demonstrating that reducing SB improves cardiovascular health. The Effect of Reducing Sedentary Behavior on Blood Pressure (RESET BP) randomized clinical trial addresses this gap by testing the effect of a 3-month SB reduction intervention on resting systolic BP.

Cocoa-flavanols enhance moderate-intensity pulmonary [Formula: see text] kinetics but not exercise tolerance in sedentary middle-aged adults.

Eur J Appl Physiol 2021 May 10. Epub 2021 May 10.

School of Sport and Exercise Science, Liverpool John Moores University, Byrom Street, Liverpool, L3 3AF, UK.

Introduction: Cocoa flavanols (CF) may exert health benefits through their potent vasodilatory effects, which are perpetuated by elevations in nitric oxide (NO) bioavailability. These vasodilatory effects may contribute to improved delivery of blood and oxygen (O) to exercising muscle.

Purpose: Therefore, the objective of this study was to examine how CF supplementation impacts pulmonary O uptake ([Formula: see text]) kinetics and exercise tolerance in sedentary middle-aged adults. Read More

The role of structure in dietary approaches for the treatment of pediatric overweight and obesity: A critical review.

Obes Rev 2021 May 5:e13266. Epub 2021 May 5.

Department of Nutrition, University of Tennessee Knoxville, Knoxville, Tennessee, USA.

A multicomponent approach for the treatment of pediatric overweight/obesity, which includes behavioral strategies to alter diet and physical activity/sedentary behavior, has graded recommendations for its use. Dietary interventions to be used within this approach do not. In adults, research indicates that strongly graded dietary interventions providing greater structure (or more control over the types/amount of food consumed) produce better weight outcomes.
