This observational study was designed to determine whether football players with a history of heat cramps have elevated fluid and sodium losses during training. During a "two-a-day" training camp, five Division I collegiate football players (20.2 +/- 1.6 y, 113 +/- 20 kg) with history of heat cramps (C) were matched (weight, age, race and position) with a cohort of teammates (19.6 +/- 0.6 y, 110 +/- 20 kg) who had never cramped (NC). Change in body weight (adjusted by fluid intake) determined…

Assessment of physical demands and fluid balance in elite female handball players during a 6-day competitive tournament.
TLDR
Fluid and electrolyte loss appear to be work rate dependent in elite female handball players, whom appear well capable of replacing fluids lost within a tournament environment.
Sweat sodium losses of professional rugby players with and without a history of cramp
TLDR
The findings of the present study do not support the theory of sweat sodium losses leading to serum electrolyte imbalances and eventual muscle cramps, and other theories regarding muscle fatigue have been postulated.
Dehydration and sodium deficit during indoor practice in elite European male team players
TLDR
Most players could benefit from increasing fluid intake between workouts to offset the high prevalence of morning hypohydration, and the exercise fluid replacement habits of professional indoor team players are adequate to prevent 2% dehydration.
Pregame urine specific gravity and fluid intake by National Basketball Association players during competition.
TLDR
Fluid intake during the game did not compensate for poor hydration status before competition and sweat losses in these players during games were substantial, therefore, both pregame and during-game hydration strategies, such as beverage availability and player education, should be emphasized.
Fluid balance of elite Brazilian youth soccer players during consecutive days of training
TLDR
It is concluded that young, native tropical soccer players arrive hypohydrated to training and that they exhibit voluntary dehydration; therefore, enhancing athletes' self-knowledge of sweat loss during training might help them to consume sufficient fluid to match the sweat losses.
Sweat Characteristics of Cramp-Prone and Cramp-Resistant Athletes.
TLDR
Receiver operating characteristic curve analysis revealed that sweat electrolyte content and SRs were predictive of EAMC-prone athletes in American football (area under curve = 0.65-0.72, p ≤ .005), but not in any other sport.
On-ice sweat rate, voluntary fluid intake, and sodium balance during practice in male junior ice hockey players drinking water or a carbohydrate-electrolyte solution.
TLDR
A single field sweat test during similar on-ice hockey practices in male junior hockey players is sufficient to evaluate fluid and electrolyte balance and a CES does not affect voluntary fluid intake during practice, compared with water, in these players.
Comparison of Sweat Rates and Sweat Electrolyte Concentrations in Collegiate Male and Female Athletes With and Without a History of Cramping
TLDR
The cramping group displayed trend toward a greater sweat rate than the non-cramping group, supporting the electrolyte-dehydration theory, and a similar sweat sodium concentration and lack of statistical significance challenge this conclusion.
Thermoregulation, Fluid Balance, and Sweat Losses in American Football Players
TLDR
The thermoregulation, fluid balance, and sweat losses of American Football players are discussed and the potential for sodium loss is higher in American Football than in other sports.

Exercise-induced muscle cramp: a prospective biochemical study in marathon runners.
TLDR
Serum electrolyte concentrations were not different between those suffering from cramp and those not so affected either before or after the race, although a significant (P less than 0.001) increase in serum sodium concentrations occurred in both groups.

TLDR
A 17-year-old, nationally ranked, male tennis player (AH) had been experiencing heat cramps during tennis match play and was ultimately able to eliminate heat cramping during competition and training by increasing his daily dietary intake of sodium.

The critical level of water deficit causing a decrease in human exercise performance: a practical field study
TLDR
It is suggested that there is a critical level of water deficit at which a decrease in aerobic and anaerobic performance occurs, and that aerobic performance may be more adversely influenced by dehydration thananaerobic power output during exercise-induced dehydration.
Effect of induced metabolic alkalosis on sweat composition in men.
TLDR
The data indicate that induced metabolic alkalosis can modify sweat composition, although it is unclear whether the secretory coil, reabsorptive duct, or both are responsible for this alteration.
Certified Athletic Trainers' Perceptions of Exercise-Associated Muscle Cramps
TLDR
Investigating ATCs' perceptions of EAMC found that humidity, temperature, training, dehydration, and electrolyte imbalance were indicated as causative factors of the muscle cramps.

TLDR
This dietary-acclimation protocol did not result in whole-body or intramuscular K+ deficits and offers no evidence to support previous claims that dietary sodium levels affect K+ balance.
Fatigue in Soldiers due to Chloride Losses. Replacement through the Use of Sodium Chloride in Drinking Water.
TLDR
It is estimated that 3 to 6 litres of sweat may be lost per 24 hours by soldiers taking part in military manoeuvres with a consequent loss of chloride of approximately 20 to 40 gm, and the authors suggest that the use of 0.5 per cent.
The effect of sodium balance on sweat sodium secretion and plasma aldosterone concentration
TLDR
Findings are inconsistent with the hypothesis that retention of sweat sodium is dependent upon a net body sodium deficit, but demonstrate that aldosterone secretion is potentiated under such conditions.
Exercise tolerance in the heat on low and normal salt intakes.
TLDR
It is concluded that moderate salt restriction does not impair the ability to exercise in a hot environment.
