Primary Outcome Measures

Name	Time	Method
The primary evaluation parameter is the concentration of mineral components in sweat.<br>The mineral components analyzed include sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), chromium (Cr), bromine (Br), and strontium (Sr).<br>The composition and quantity of electrolyte loss from the entire body are estimated based on changes in body weight and fluid intake.

Secondary Outcome Measures

Name	Time	Method
Secondary evaluation parameters include urine samples collected before exercise, heart rate during exercise, and temperature measurements taken during breaks.<br>Using the BDHQ (Brief Diet History Questionnaire), the estimated intake of trace elements from regular dietary habits is assessed.<br>The previous day's salt intake is measured from the urine samples collected before exercise.<br>Analysis is conducted to explore the relationship between heart rate during exercise, changes in body temperature, and the components of sweat.<br>Additionally, analyses are performed to examine the relationship between regular dietary intake patterns and the composition of sweat, as well as the relationship with fluid intake.
