Summary
Heart rate variability (HRV) is a measure of the variation in time between each heartbeat. It is an indirect and ubiquitous biomarker of performance readiness and recovery measured by most consumer-grade wearable fitness trackers. However, there is little documented on the relationship between HRV, training load, and performance measures in the Real-World. Whoop wrist-worn activity trackers have been validated against the gold-standard Electrocardiography (ECG) for HRV and HR measurements. Whoop leverages photoplethysmography (PPG) technology to continuously track (HR, HRV, respiratory rate, energy expenditure) and provides, daily, individual insights, trends, and coaching to improve strain, sleep, and recovery. Research has demonstrated that heart rate variability (HRV) guided training may be more optimal compared to predetermined training for aerobic exercise improvements. The purpose of this study is to assess the feasibility of providing personalized training recommendations based on HRV measured by a consumer-grade wearable (Whoop) in a real-world setting to better understand the HRV relationship with performance.
Eligibility
Inclusion Criteria6
- Actively participating in resistance training 2-4 times per week.
- Age 21-50 years, male and female.
- Subject is willing to refrain from vigorous exercise (light physical activity only) 24 hours prior to visit(s).
- Subject is willing to avoid alcohol consumption 24 hours prior to visit(s).
- Subject is willing to provide consent.
- Subject is able to continuously wear a wrist-worn device, including during sleep, except when submerged underwater (i.e., swimming, bathing).
Exclusion Criteria13
- Individual has a condition the Investigator believes would interfere with his ability to provide informed consent, comply with the project/study protocol, which might confound the interpretation of the project/study results or put the person at undue risk.
- Those with a medical history that would interfere with the results of this study.
- Under the care of a physician.
- Skin sensitivities.
- Sleep disorders.
- Using prescription medications that would impact sleep.
- If female, you are not pregnant, planning to get pregnant or currently breast feeding.
- Smoker.
- Not able to wear wrist-worn device continuously.
- Lack of proficiency in English.
- Lack of proficiency or access to the internet and email address.
- Participation in another clinical trial within the past 30 days.
- Subject is employed by, or has a parent, guardian, or other immediate family member employed by a company that manufactures any products that compete with any Gatorade product. If subject is unsure if a company would be considered a competitor to Gatorade, they will be asked to please let the study investigator know the name of the other company and the nature of their relationship to that company before they sign the informed consent.
