Effect of carbohydrate feeding on the bone metabolic response to running
Sale C, Varley I, Jones TW, James RM, Tang JC, Fraser WD, Greeves JP. Effect of carbohydrate feeding on the bone metabolic
response to running. J Appl Physiol 119: 824 – 830, 2015. First published August 6, 2015; doi:10.1152/japplphysiol.00241.2015.—
Bone resorption is increased after running, with no change in bone formation. Feeding during exercise might attenuate this increase,
preventing associated problems for bone. This study investigated the immediate and short-term bone metabolic responses to carbohydrate ...

Ecologically Valid Carbohydrate Intake during Soccer-Specific Exercise Does Not Affect Running
Performance in a Fed State
Abstract: This study assessed the effect of carbohydrate intake on self-selected soccer-specific runnin performance. Sixteen male soccer players (age 23 ± 4 years; body mass 76.9 ± 7.2 kg; predicted VO2max = 54.2 ± 2.9 mL·kg−1 ·min−1; soccer experience 13 ± 4 years) completed a progressive multistage fitness test, familiarisation trial and two experimental trials, involving a modified version
of the Loughborough Intermittent Shuttle Test (LIST) to simulate a ...

Critical evaluation of food intake and energy balance in young modern pentathlon athletes: a cross-sectional study
Abstract
Background: Modern pentathlon comprises five sports: fencing, swimming, equestrian jumping, and a combined
event of pistol shooting and running. Despite the expected high energy demand of this sport, there are few
studies that provide support for the nutritional recommendations for pentathletes. The purpose of the present
study was to evaluate young modern pentathlon athletes with respect to body composition, biochemical profile,
and consumption of food and ...

Carbohydrate Nutrition and Team Sport Performance
Abstract The common pattern of play in ‘team sports’ is ‘stop and go’, i.e. where players perform repeated bouts of brief high-intensity exercise punctuated by lower intensity activity. Sprints are generally 2–4 s long and recovery between sprints is of variable length. Energy production during brief sprints is derived from the degradation of intra-muscular phosphocreatine and glycogen (anaerobic metabolism). Prolonged periods of multiple sprints drain muscle glycogen stores, leading to a decrease in power
output and a ...
