ABSTRACT
Sweat rate, fluid loss, and sodium loss directly impact performance during prolonged exercise bouts. The Gatorade Gx Sweat Patch (Gx SP) is a wearable device that tracks these metrics in the user. Having this information allows athletes to strategize their fluid and electrolyte consumption. This randomized and counterbalanced study will determine the validity and accuracy of the Gx SP’s prediction of sweat rate, fluid loss, and sodium loss compared to lab-based measurements. Healthy runners and basketball players will be recruited to participate in two running sessions on a treadmill. Participants will be asked to run at low-intensity and moderate-intensity, determined by heart rate reserve. Hydration status and sodium loss will be determined pre-and post-exercise via body weight, bioelectric impedance analysis (BIA), and urine and blood samples. While running, the participant will wear the Gx SP, an additional absorbent gauze pad, and a heart rate (HR) monitor. Running intensity will be monitored by HR and corresponding HRR values. After completing the exercise, sweat rate, fluid loss, and sodium loss will be generated via the Gx SP. The absorbent gauze will be analyzed for sodium loss. Body weight and blood and urine samples will be obtained again and compared to the pre-test samples. Participants will return within 2 to 14 days to complete the opposite running condition. To determine the validity of the device, the validation criteria for the Gx SP is: p > 0.05, mean absolute percentage error < 10.0%, Pearson Correlation > 0.70, and Lin’s Correlation Coefficient Concordance > 0.70.

Hello Macy!
Your talk about the validation of the Garmin Fenix 6S Maximal Oxygen Consumption Estimate was very interesting, I am an student athlete and I found Vo2 max topic incredibly fascinating, because there is a lot of factors that can influence the improvement of this element. Athletes who perform on the highest level needs to be aware of their Vo2 max level because that helps them improve their performance level. In swimming for example the best way to improve is by pushing your Vo2 max limit higher and higher. Thank you for you presentation!
Good evening Macy! I really enjoyed your lightning talk discussing the validation of the Garmin Fenix 6S Maximal Oxygen Consumption Estimate. Loving sports I founding it super appealing to see how the process actually works and the background information regarding the subject. Until now I had no idea of the benefits that the Garmin Fenix 6S Maximal Oxygen Consumption device has to offer. Thank you for this informational and intriguing information.
Thanks for watching, Ethan!
Macy! Great job on lightning talk #2 🙂
Thanks, James!
Hello Macy,
I really enjoyed listening to your lightning talk about the validation of the Garmin Fenix 6S Maximal Oxygen Consumption Estimate. Being that i am an athlete here myself, I found it really interesting that the watch provided a valid estimate of the VO2 Max of the person wearing it. I think it is important for athletes to be aware of their VO2 Max in order to get the accurate training to improve their performance. Knowing that this watch is accurate in predicting this, can make it easier for athletes ti gain this knowledge without having to go into a lab to gather that data. Great talk, Macy!
Thanks, Julia! I completely agree. Thanks for watching!
