Fluid Balance and Endurance Exercise Performance

Current Sports Medicine Reports, 2003
Dehydration alters cardiovascular, thermoregulatory, central nervous system, and metabolic functions. One or more of these alterations will degrade endurance exercise performance when dehydration exceeds 2% of body weight. These performance decrements are accentuated by heat stress.

Fluids and hydration in prolonged endurance performance

Nutrition, 2004
Numerous studies have confirmed that performance can be impaired when athletes are dehydrated. Endurance athletes should drink beverages containing carbohydrate and electrolyte during and after training or competition. Carbohydrates (sugars) favor consumption and Na(+) favors retention of water.

The Effect of Fluid Replacement on Endurance Performance

Journal of Strength and Conditioning Research, 2001
The purpose of this study was to examine the effects of fluid replacement on power output (PO), rating of perceived exertion (RPE), heart rate (HR), body weight (BW), urine osmolarity (Uosm), and urine electrolyte concentrations ([UNa+], [UK+], [UCl-]) in physically active men (n = 4) and women (n = 7).

The effect of salbutamol on performance in endurance cyclists

European Journal of Applied Physiology and Occupational Physiology, 1996
The effect of salbutamol (S) on cycling performance was examined in 15 highly trained non-asthmatic male cyclists. A double-blind, randomized cross-over design was used with S or placebo (P) administered using a metered-dose inhaler and a spacer device 20 min before each testing session.

The Laboratory Assessment of Endurance Performance in Cyclists

Canadian Journal of Applied Physiology, 1994
Performance in endurance activities depends on maximal aerobic capacity [Formula: see text] and the ability to sustain a high percentage of [Formula: see text] over time. This study examined whether noninvasive laboratory measures would be valid predictors of endurance performance in an individual-start bicycle race (TT).

Caffeine and Taurine Enhance Endurance Performance

International Journal of Sports Medicine, 2009
Caffeine enhances endurance performance; however, its effect on accumulated lactate remains unclear. Conversely, taurine, which also enhances endurance performance, decreases accumulated lactate. In this study, the effect of combination of caffeine and taurine on endurance performance was assessed.

Endurance running performance in athletes with asthma

Journal of Sports Sciences, 1990
Laboratory assessment was made during maximal and submaximal exercise on 16 endurance trained male runners with asthma (aged 35 +/- 9 years) (mean +/- S.D.). Eleven of these asthmatic athletes had recent performance times over a half-marathon, which were examined in light of the results from the laboratory tests.

Physiological determinants of endurance exercise performance

Journal of Science and Medicine in Sport, 1999
Performance in endurance events is typically evaluated by the power or velocity that can be maintained for durations of 30 min. to four hours. The two main by-products of intense and prolonged oxidative metabolism that can limit performance are the accumulation of hydrogen ion (i.e. lactic acidosis) and heat (i.e. hyperthermia).

Vegetarian dietary practices and endurance performance

The American Journal of Clinical Nutrition, 1988
Confounding influences of varying fat, protein, and carbohydrate (CHO) levels, training habits, and lifestyle patterns make the interpretation of specific influences of the diet on endurance performance unclear. In general, exhaustion during prolonged, hard endurance exercise is tied to low muscle glycogen stores.
