CONTEXT Uncertainty exists regarding the effect of sustained sweating on sweat mineral-element composition. PURPOSE To determine the effect of multiple hours of exercise-heat stress on sweat mineral concentrations. METHODS Seven heat-acclimated subjects (6 males, 1 female) completed 5 x 60 min of treadmill exercise (1.56 m/s, 2% grade) with 20 min rest between exercise periods in 2 weather conditions (27 degrees C, 40% relative humidity, 1 m/s and 35 degrees C, 30%, 1 m/s). Sweat was… 

Figures and Tables from this paper

Effect of heat acclimation on sweat minerals.

Exercise-heat acclimation conserves arm sweat mineral concentrations and possibly whole-body sweat losses of calcium, copper, and magnesium, and may reduce sweat iron and zinc concentrations.

Exercise-induced trace mineral element concentration in regional versus whole-body wash-down sweat.

Regional sweat [Ca], [Mg], and [Cu] are not accurate surrogates for or significantly correlated with WBW sweat composition.

Ingestion of sodium plus water improves cardiovascular function and performance during dehydrating cycling in the heat

It is suggested that pre‐exercise ingestion of salt plus water maintains higher plasma volume during dehydrating exercise in the heat without thermoregulatory effects, which maintains cardiovascular function and improves cycling performance.

Surface contamination artificially elevates initial sweat mineral concentrations.

Several sweat mineral element concentrations decline with serial sampling, and initial arm bag sweat mineral concentrations were greater than those in the sweat pouch, and [Ca], [Cu], [Mg], and [Zn] declined 26-76% from initial to the subsequent samples, becoming similar to sweat pouch.

Influence of Physical Exercises on Salt Loss and Sweat Rate Level

The present study suggested that, there was a significant association among the selected variables among the sweat Na, Nacl, sweat rate and percentage of loss of body mass level.

A Case-Series Observation of Sweat Rate Variability in Endurance-Trained Athletes

The significant differences in SR within each temperature range indicates a single assessment may not accurately represent an individual’s typical SR even in similar environmental conditions.

Evaluation of the Megaduct sweat collector for mineral analysis

TheMegaduct sweat collector appears to avoid skin encapsulation and hidromeiosis, and captures sweat with similar mineral concentrations as reported in the literature for pouches, however, the filling time of the Megaduct may not capture possible changes in sweat mineral concentrations that are documented to occur in as little as 15 to 30 min.

Fluid and electrolyte losses associated with working/exercising for prolonged periods in thermally stressful environments

Based on the findings from three studies, fluid and electrolyte replacement recommendations have been made for both manual workers and athletes working and exercising in thermally stressful environments and increasing the sodium content of fluid and food provided to workers is warranted and may reduce the incidence of work related illness and accidents.

The effects of heat and exercise on sweat iron loss.

Results suggest that the use of resting sweat iron concentration to estimate iron loss for 1 h of exercise in neutral environments is accurate but may overestimate iron loss during exercise in hot environments and during more prolonged exercise.

The reproducibility of closed-pouch sweat collection and thermoregulatory responses to exercise–heat stress

It is proposed that moderate variations in sweat composition were influenced by variations in the local sweat rate, which were induced by application of the pouch.

Sweat iron and zinc losses during prolonged exercise.

A possible iron conservation that prevents excessive iron loss during prolonged exercise is suggested.

There was a significant interaction of time, gender, and temperature for whole-body sweat rates (WBSR).

Seasonal variation of trace element loss to sweat during exercise in males

It is suggested that there was no significant difference in the amount of loss of trace elements in sweat due to exercise between summer and winter.

Concentrations of trace elements in sweat during sauna bathing.

The amount of trace elements in sweat measured by the arm bag method was less than that by the whole body method; significant differences were observed in Fe and Mn amounts.

Variations in Regional Sweat Composition in Normal Human Males

This project aimed to quantify the regional distribution of sweat composition over the skin surface and to determine whether sweat constituent concentrations collected from regional sites can estimate whole‐body concentrations, and is the first investigation to report a positive relationship between sweat [K+] and [lactate.

Exercise-induced changes in blood minerals, associated proteins and hormones in women athletes.

Exercise-induced changes in minerals may reflect release from other tissues and/or changes in the concentration of associated proteins, whether these changes serve adaptive and/ or specific functions during exercise is unknown.

An improved method for collection of whole body sweat from exercising subjects is described, involved construction of a plastic frame that supports a large plastic bag within which the subject exercises.
