An observational study in Female Athletes and Healthy Women, sponsored by PepsiCo Global R&D. Enrolling by invitation at 1 site in United States. Open to female participants aged 16 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-20.
Sponsored by PepsiCo Global R&D (part of PepsiCo, Inc.) · Observational
In May 2026, the Gatorade Brand launched the "Body of Science" (BoS), a multi-year research initiative aimed at closing the gender gap in sports science. While research is the heart of the BoS initiative, the platform also provides external engagement opportunities to connect with women.
To help tell the story, the Gatorade Brand is interested in ways our current roster of female athletes can participate in the research. To support this request, we developed a battery of tests designed to provide descriptive information about elite female athletes from a variety of sports, including attributes to contribute to athletic performance but also everyday information that supports overall well-being.
PepsiCo Global R&D is the lead sponsor of 103 studies on the registry; 8 are open to participants now.

Body composition
lean soft tissue vs fat mass measured by either BodPod or DXA
Time frame: Day 1
Resting Metabolic Rate
After 15 minute rest interval, participants will lie on table and remain as still as possible while breathing into a mask. The mask will collect expired gas for \~15-30 minutes to give a measure or baseline energy requirements for day-to-day activity.
Time frame: Day 1
Fuel Profile
Incremental exercise test (on treadmill or cycle ergometer) in which exercise intensity is progressively increased until participant chooses to stop. Participant will be encouraged to go as long as possible. During the test, participants will continuously breathe into a mask while exhaled gas is collected and measured and used to display subjective substrate metabolism markers (carb vs fat burn)
Time frame: Day 1
VO2 Max
Incremental exercise test in which exercise intensity is progressively increased until participants reach volitional fatigue. are no longer able to continue exercising. During the test, participants will continuously breathe into a mask while exhaled air is collected and measured to determine the maximal rate of oxygen used during exercise bout.
Time frame: Day 1
Capillary lactate
Collected every stage during a fuel profile/Vo2max test
Time frame: Day 1
Force Plate
participants will perform either a countermovement jump (CMJ) or an Isometric Mid-Thigh Pull (IMTP) as measure of power or strength output respectively. For CMJ, participants will stand with legs shoulder width apart on plates then will jump upward with max force to display power output. For IMTP, participants will stand with legs shoulder width apart on plates and will pull a stationary barbell upward as a measure of how much strength can be exerted on the bar. These maximal pulls will last 3-5 seconds.
Time frame: Day 1
Isokinetic (Dynometer)
Researchers will use a computer-controlled device to carry out flexion, extension, and rotation movements across the shoulder, elbow, hip, knee, and/or ankle joints to analyze muscle control, fatigue, and muscle strength. Participants will be asked to carry out contractions at a set pace, at maximal force, or as quickly as possible. Participants will be given 30 seconds rests between movement tests
Time frame: Day 1
Neck Strength
Participants will attach neck to strength device and testing will take place in the plane of interest (flexion, extension, lateral flexion, retraction/protraction). No visible movement will occur. Participants will old steady against resistance in order to generate force.
Time frame: Day 1
Hand Grip (Dynometer)
Participants will used a computer-controlled handgrip device to analyze handgrip fatigue and grip strength. Participants will perform 3 maximal handgrip contractions with 30 seconds separating each contraction. Participants may also perform maximal handgrip contraction and be timed to determine how long it takes to reach 70% of maximal force. Finally, participants may perform a series of submaximal contractions, squeezing for 3 seconds then resting for 3 seconds.
Time frame: Day 1
Dynavision (D2)
Participants will stand in front of D2 and complete preset protocol to measure cognition and reaction time. Participants will be required to press buttons as they light up and recite numbers as they appear on a screen, and score is recorded.
Time frame: Day 1
Reflexion Edge
Participants complete preset protocols to measure cognition and reaction time. Protocols vary from sport specific drills to testing hand-eye coordination, peripheral vision, reaction time, hand speed, etc
Time frame: Day 1
Bone Mineral Density
Measured via DXA scan
Time frame: Day 1
Adverse Events
Documented changes in health and symptoms as a safety measurement
Time frame: Through study completion, an average of 2 days
