Effects of carbohydrate combined with caffeine on repeated sprint cycling and agility performance in female athletes
Anaerobic capacity Ergogenic aids Fatigue Hormone Metabolic substrate Nutrition
2015/7/29
Caffeine (CAF) has been shown to improve performance during early phase of repeated sprint exercise; however some studies show that CAF also increases the magnitude of physical stress represented by a...
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...
Low-protein vegetarian diet does not have a short-term effect on blood acid–base status but raises oxygen consumption during submaximal cycling
Nutrition Acid–base balance Aerobic performance
2015/7/24
Acid–base balance refers to the equilibrium between acids and bases in the human body. Nutrition may affect acid–base balance and further physical performance. With the help of PRAL (potential renal a...
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 ...

thermogenic nutritional supplement cycling time to exhaustion muscular strength college-aged men
2015/7/16
The purpose of the present study was to examine the acute effects of a thermogenic nutritional supplement containing caffeine, capsaicin, bioperine, and niacin on muscular strength and endurance perfo...
Energy balance during two days of continuous stationary cycling
Energy balance two days stationary cycling
2015/7/13
This study examined the capabilities of an ultraendurance athlete to self-regulate their diet during an attempt on the record for the longest period of stationary cycling. The attempt required the ath...

Maximal inspiratory pressure respiratory muscle fatigue repeated-sprint ability mouth pressure manometer
2015/5/26
This study examined respiratory muscle strength using the POWERbreathe® inspiratory muscle trainer (i.e., ‘S-Index’) before and after repeated-sprint cycling for comparison with maximal inspirato...
Effects Of Cadence on Aerobic Capacity Following a Prolonged, Varied Intensity Cycling Trial
Power output energy expenditure varied intensity cycling efficiency lactate oxygen consumption
2015/5/21
We determined if high cadences, during a prolonged cycling protocol with varying intensities (similar to race situations) decrease performance compared to cycling at a lower, more energetically optima...
