Sex-Related Differences in Self-Paced All Out High-Intensity Intermittent Cycling:Mechanical and Physiological Responses
Oxygen uptake sexual dimorphism anaerobic power reserve
2016/7/7
The purpose of this study was to compare sex-related responses to a self-paced all out high-intensity intermittent exercise (HIIE). 9 women and 10 men were submitted to a maximal incremental test (to ...
Carbohydrate mouth rinsing has no effect on power output during cycling in a glycogen-reduced state
Ergogenic aid Fluid ingestion Time trial Sports drink Mouthwash Supplementation
2016/5/16
Background:The effect of mouth rinsing with a carbohydrate (CHO) solution on exercise performance is inconclusive with no benefits observed in the fed state. This study examined the effect of CHO mout...
Effects of Sprint Interval Cycling on Fatigue, Energy, and Cerebral Oxygenation
HIGH-INTENSITY INTERVAL CYCLING MOOD STATE NEAR-INFRARED SPECTROSCOPY
2017/4/13
Introduction: Feelings of fatigue are reduced after a session of continuous exercise of low-to-moderate intensity lasting 20 min or more, but only when feelings of energy are increased. Feelings of fa...
Cycling Time Trial Is More Altered in Hypobaric than Normobaric Hypoxia
NORMOBARIC HYPOXIA HYPOBARIC HYPOXIA PERFORMANCE EXERCISE
2017/4/13
Purpose: Slight physiological differences between acute exposure in normobaric hypoxia (NH) and hypobaric hypoxia (HH) have been reported. Taken together, these differences suggest different physiolog...
Modeling Intermittent Cycling Performance in Hypoxia Using the Critical Power Concept
ALTITUDE WORK-BALANCE HIGH-INTENSITY FATIGUE
2017/4/13
Purpose: This study investigated the efficacy of an intermittent critical power (CP) model, termed the “work-balance” (W′BAL) model, during high-intensity exercise in hypoxia (HYPO).
Methods: Eleven ...
Peripheral and Central Fatigue Development during All-Out Repeated Cycling Sprints
PERIPHERAL FATIGUE CENTRAL FATIGUE RECOVERY CENTRAL MOTOR DRIVE REPEATED SPRINTS
2017/4/13
Purpose: We investigated the development and recovery of peripheral and central fatigue during repeated cycling sprints and its influence on power output.
Methods: On six separate days, 12 healthy ma...
Effects of Workloads and Cadences on Frontal Plane Knee Biomechanics in Cycling
KNEE ABDUCTION MOMENT KNEE ADDUCTION MOMENT KNEE FLEXION MOMENT
2017/4/13
Although effects of workload and cadence on sagittal plane knee biomechanics in cycling have been widely studied, few studies have examined their impact on the frontal plane.
Purpose: The purpose of ...
Muscle Pain as a Regulator of Cycling Intensity: Effect of Caffeine Ingestion
EXERCISE PERRORMANCE ADENOSINE ANTAGONISM
2017/4/13
Caffeine ingestion improves endurance time trial performance. However, the ergogenic mechanism of action remains unresolved. One potential explanation for caffeine’s performance-enhancing effect is an...
Cycling Exercise Training Alleviates Hypoxia-Impaired Erythrocyte Rheology
EXERCISE HYPOXIA ERYTHROCYTE HEMORHEOLOGY
2017/4/13
Purpose: Physical exercise or hypoxic exposure influences hemorheology and acid–base homeostasis. Band 3 protein in erythrocytes modulates cells’ rheological properties and anion transport ability. Th...

Aerobic metabolism blood glucose concentration all-out sprint test
2016/3/11
The purpose of this study was to compare the effects of running versus cycling training on sprint and endurance capacity in inline speed skating. Sixteen elite athletes (8 male, 8 female, 24 ± 8 yrs) ...
Limitations of Spectral Electromyogramic Analysis to Determine the Onset of Neuromuscular Fatigue Threshold during Incremental Ergometer Cycling
Cycling neuromuscular fatigue surface electromyography motor unit recruitment spectral EMG analysis
2016/3/11
Recently, a new method has been proposed to detect the onset of neuromuscular fatigue during an incremental cycling test by assessing the changes in spectral electromyographic (sEMG) frequencies withi...
A Comparison between Alpine Skiing, Cross-Country Skiing and Indoor Cycling on Cardiorespiratory and Metabolic Response
Borg blood lactate cross-country skiing cycling energy expenditure fitness level oxygen uptake gender
2016/3/11
Since physical inactivity especially prevails during winter months, we set out to identify outdoor alternatives to indoor cycling (IC) by comparing the metabolic and cardiorespiratory responses during...
Evaluation of Electromyographic Frequency Domain Changes during a ThreeMinute Maximal Effort Cycling Test
