Six-minute rowing test: a valid and reliable method for assessing power output in amateur male rowers.

Background: Standardized tests are currently available to assess power output in elite rowers. However, there are no valid and reliable tests to assess power output in amateur rowers.

Objective: This study aimed to determine the validity and reliability of a 6-min rowing ergometer test (6-min) as a predictor of power output (PO) in amateur male rowers.

Intercostal Muscles Oxygenation and Breathing Pattern during Exercise in Competitive Marathon Runners.

The study aimed to evaluate the association between the changes in ventilatory variables (tidal volume (Vt), respiratory rate (RR) and lung ventilation (V.E)) and deoxygenation of (∆SmO-) during a maximal incremental exercise in 19 male high-level competitive marathon runners. The ventilatory variables and oxygen consumption (V.

Socio-Demographic Correlates of Total and Domain-Specific Sedentary Behavior in Latin America: A Population-Based Study.

Purpose: The aim of this study was to identify socio-demographic correlates of total and domain-specific sedentary behavior (SB).

Methods: Cross-sectional findings are based on 9218 participants (15-65 years) from the Latin American Study of Nutrition and Health. Data were collected between September 2014 and February 2015.

[Effects of acute supplementation with beta-alanine on a limited time test at maximum aerobic speed on endurance athletes].

Introduction: the beta-alanine (BA) is one of the ergogenic aid most used by athletes, but the majority of the studies center the research on chronic supplementation. Objectives: to determine the acute effect of BA supplementation on a limited time test (LTT) at maximum aerobic speed (MAS) on endurance athletes. Material and method: eleven endurance athletes (VO2max 61.
