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...
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...
The effect of an acute ingestion of Turkish coffee on reaction time and time trial performance
Caffeine Exercise Cognition Ergogenic effects
2015/11/2
The purpose of this study was to examine the ergogenic benefits of Turkish coffee consumed an
hour before exercise. In addition, metabolic, cardiovascular, and subjective measures of energy, focus an...
Menstrual cycle phase and carbohydrate ingestion alter immune response following endurance exercise and high intensity time trial performance test under hot conditions
Prolonged exercise Leukocytes Cytokines
2015/7/29
We investigated the effects of menstrual cycle phase and carbohydrate (CHO) ingestion on immune response during endurance exercise at 30°C. Six healthy women completed 4 trials comprising 90 min of cy...
Performance during a 20-km cycling time-trial after caffeine ingestion
Ergogenic aid Sports performance Perceived exertion
2015/7/29
In a double-blind placebo-controlled crossover study, 13 male cyclists (26 ± 10 y, 71 ± 9 kg, 176 ± 6 cm) were randomized into 2 groups and received caffeine (CAF) ...
Sodium supplementation has no effect on endurance performance during a cycling time-trial in cool conditions:a randomised cross-over trial
Sodium Salt Hyponatremia Endurance exercise Hydration Fluid balance Thirst
2015/7/27
Sodium ingestion during exercise may exert beneficial effects on endurance performance by either its ability to attenuate the decrease in plasma volume or reduce the risk of Exercise Associated Hypona...
ffects of lowering body temperature via hyperhydration, with and without glycerol ingestion and practical precooling on cycling time trial performance in hot and humid conditions
Euhydration Hypothermia Self-paced endurance performance Perception of effort Environmental heat gain Metabolic heat gain Heat dissipation
2015/7/24
Hypohydration and hyperthermia are factors that may contribute to fatigue and impairment of endurance performance. The purpose of this study was to investigate the effectiveness of combining glycerol ...
Recovery from a cycling time trial is enhanced with carbohydrate-protein supplementation vs. isoenergetic carbohydrate supplementation
cycling time carbohydrate-protein
2015/7/14
Under these experimental conditions, liquid C+P ingestion immediately after
exercise increases fat oxidation, increases recovery, and improves subsequent same day, 60 min
efforts relative to isoener...
Sodium Phosphate Supplementation and Time Trial Performance in Female Cyclists
Ergogenics endurance performance 2,3-DPG
2015/5/25
This study investigated the effects of three doses of sodium
phosphate (SP) supplementation on cycling 500 kJ (119.5 Kcal)
time trial (TT) performance in female cyclists.
Effect of Creatine Loading on Oxygen Uptake during a 1-km Cycling Time Trial
V˙O2 SLOW COMPONENT ACCUMULATED OXYGEN DEFICIT PACING ALL-OUT SUPPLEMENTATION CYCLIST
2017/4/20
Purpose: For the first time, we investigated the effects of altering cellular metabolic capacitance, via a 5-d creatine (Cr) loading protocol (20 g·d−1), on oxygen uptake (V˙O2), accumulated oxy...
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...
Effect of Heat and Heat Acclimatization on Cycling Time Trial Performance and Pacing
EXERCISE HOT AMBIENT CONDITIONS TEMPERATURE ACCLIMATIZATION HYPERTHERMIA FATIGUE
2017/4/14
Purpose: This study aimed to determine the effects of heat acclimatization on performance and pacing during outdoor cycling time trials (TT, 43.4 km) in the heat.
Methods: Nine cyclists performed thr...
Time Trial Performance and Pacing in Heat is Determined by Rate of Heat Gain
Time Trial Performance and Pacing Rate of Heat Gain
2017/4/14
The very elegant study by Racinais et al. (6) shows for the first time that at least one outcome of heat acclimatization is altered pacing strategy. A key finding from their Figure 1 was the attenuate...
Fluid ingestion strategies of competitive cyclists during 40 km time trial competition
competitive cyclists trial competition
2015/4/3
Loss of fluid during prolonged exercise has been purported to be a cause of fatigue (Below et al., 1995; Walsh
et al., 1994, for example). A plethora of information regarding ‘optimal’ fluid replace...
