Effects of omega-3 supplementation in combination with diet and exercise on weight loss and body composition.

Background: In addition to the metabolic and cardiovascular benefits of omega-3 (n-3) fatty acids, several studies have suggested an added weight loss-enhancing benefit to this supplement.

Objective: The objective was to assess whether supplemental omega-3 fatty acids in conjunction with diet and exercise augment weight loss over a 6-mo period.

Design: In a single-institution, placebo-controlled, randomized clinical trial, 128 individuals with a body mass index (in kg/m(2)) between 26 and 40 were assigned to receive 5 omega-3 [3.

Cardiorespiratory fitness, adiposity, and serum 25-dihydroxyvitamin d levels in men.

Purpose: we examined the cross-sectional associations between cardiorespiratory fitness (CRF) level, different measures of adiposity, and serum 25-dihydroxyvitamin D levels (SVD) in men.

Methods: a total of 2317 men completed a baseline health examination between 2005 and 2009. Clinical measures included body mass index (BMI), waist circumference (WC), waist-to-hip ratio (W:Hip), percent body fat, CRF quantified as duration of a maximal treadmill exercise test, and measurement of SVD.

DATE: Depressed adolescents treated with exercise: Study rationale and design for a pilot study.

There is an important need for non-medication interventions for depressed youth. The aim of this study is to evaluate the feasibility of using a standardized aerobic exercise regime to treat non-medicated clinically depressed adolescents based on adherence and completion rates, including 1) establishing effect sizes for the primary outcomes including the Chidren's Depression Rating Scale - Revised (CDRS-R) and Actical (energy expenditure data) as well as selected secondary outcomes; (e.g.
