Observational Study of Sweat in Female Athletes
This study is looking at how much female athletes sweat and how much sodium (salt) is in their sweat during their regular sports practices. Researchers want to understand the typical sweat rates and sodium loss in female athletes aged 13 and older across various sports like basketball, soccer, and volleyball. You would wear a sweat patch during a single team practice session. The main goals are to measure the sodium concentration in your sweat, your overall sweat rate, and how much sodium you lose through sweat. This information can help us better understand hydration needs for female athletes.
- Study design
- This is an observational study, meaning researchers will collect information without giving any specific treatments. It aims to enroll 500 female athletes.
- What's involved
- You would participate in a single day of testing, wearing a sweat patch during one of your regular coach-led team sports practice sessions.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your sweat measurements will be taken during a single practice session, from start to end. There is no specified follow-up period after this session.

What this trial measures
- Regional sweat [Na+]One day from start through end of a single coach-led normal training practice session. Practice duration will be dictated by coaching staff.
Absorbent patch technique (3M TegadermTM + Pad; 3M, St. Paul, MN; pad size 10 cm2 with an absorbent capacity of \~1.3 g) to left and right dorsal arm. An additional patch on the right scapula may be added depending on the accessibility to the sites on the body and the nature of the sport. Analyzed using a HORIBA (LAQUAtwin Na-11)
- Whole body sweat rate (WBSR) WBSROne day from start through end of a single coach-led training normal training practice session. Practice duration will be dictated by coaching staff.A
Pre- versus post body mass on scale, taking into account food and fluid intake, urine and stool output
- Rate of sweat sodium loss (RSSL)One day from start through end of a single coach-led normal training practice session. Duration will be dictated by coaching staff.
The rate of sodium sweat loss (RSSL) will be determined as the product of sweat \[Na+\] and whole-body sweat rate (WBSR)
