Oral L-citrulline supplementation enhances cycling time trial performance in healthy trained men: Double-blind randomized placebo-controlled 2-way crossover study
Ergogenic Human L-Citrulline Nitric oxide (NO) Sport performance
2016/3/1
Background: Many human studies report that nitric oxide (NO) improves sport performance. This is because NO is
a potential modulator of blood flow, muscle energy metabolism, and mitochondrial respira...
Physiological Demands of Simulated Off-Road Cycling Competition
Gerhard Smekal Serge P. von Duvillard Maximilian Hö rmandinger Roland Moll Mario Heller Rochus Pokan David W. Bacharach Linda M. LeMura Paul Arciero
2016/2/23
The purpose of the study was to measure the demands of off-road cycling via portable spirometry, leg-power output (PO), heart rate (HR) and blood lactate (BLa) concentration. Twenty-four male competit...
The Contribution of "Resting" Body Muscles to the Slow Component of Pulmonary Oxygen Uptake During High-Intensity Cycling
Muscle oxygenation near infrared spectroscopy oxygen uptake kinetics arm exercise
2015/5/13
Oxygen uptake (VO2) kinetics during moderate constant-workrate (WR) exercise (>lactate-threshold (θL)) are well described as exponential. AboveθL, these kinetics are more complex, consequent to the de...
Differences between the Vastus Lateralis and Gastrocnemius Lateralis in the Assessment Ability of Breakpoints of Muscle Oxygenation for Aerobic Capacity Indices During an Incremental Cycling Exercise
Maximal incremental exercise test aerobic capacity index assessment ability near infrared spectroscopy linear regression
2015/5/13
In recent years, breakpoints (Bp) of muscle oxygenation have been measured in local muscles using near infrared spectroscopy (NIRS) to assess (predict) systemic aerobic capacity indices [lactate thres...

Effect of the Rotor Crank System on Cycling Performance
Gross efficiency cycling performance bicycle equipment
2015/4/23
The aim of this study was to evaluate the impact of a novel crank system on laboratory time-trial cycling performance. The Rotor system makes each pedal independent from the other so that the cranks a...
Effect of Energy Expenditure and Training Status on Leptin Response to Sub-Maximal Cycling
Hormones anaerobic training acute exercise
2015/4/22
We examined the leptin response and related hormones during and after two sub-maximal exercise protocols in trained and untrained subjects. During this study, plasma concentrations of leptin [Lep], in...
High-Dose Inhaled Salbutamol Does Not Improve 10-km Cycling Time Trial Performance
INHALED β2-AGONISTS EXERCISE-INDUCED BRONCHOCONSTRICTION DOPING CONTROL ERGOGENIC AIDS ATHLETE CARE
2017/4/20
Background: β2-agonists are on the World Anti-Doping Agency’s list of prohibited substances; however, athletes are allowed to treat symptoms of exercise-induced bronchoconstriction with a maximal dail...
Neuromuscular Strategies during Cycling at Different Muscular Demands
PEDALING EMG SAMPLE ENTROPY MUSCLE COORDINATION
2017/4/19
Purpose: This study investigated muscle coordination while pedaling at 150 and 300 W with a cadence of 90 rpm. Changes in the variability of the electromyographic (EMG) signals were quantified in 14 s...
Muscle Fatigue Increases Metabolic Costs of Ergometer Cycling without Changing VO Slow Component
Muscle fatigue energy cost oxygen uptake
