Advancing the science of sleep, recovery, and athletic performance through rigorous clinical research and wearable technology.
The HERO Lab — Human Enhancement Recovery Optimization — is a research collaboration between UCLA and UCSF dedicated to advancing the science of human performance and recovery.
In partnership with WHOOP, we combine wearable biometric data with rigorous clinical trial methodology to answer the questions that matter most to athletes: How do I sleep better? How do I recover faster? How do I perform at my peak?
Our research moves beyond one-size-fits-all approaches. By integrating continuous physiological monitoring with objective performance testing, we identify individualized strategies for sleep optimization, targeted supplementation, and recovery protocols.
Our clinical trials use randomized, placebo-controlled designs combined with continuous wearable monitoring to generate high-quality evidence.
NCT07015047 · Randomized Placebo-Controlled Trial
Investigating whether brain-targeted magnesium supplementation (MgT) can enhance sleep architecture, autonomic recovery, and physical performance in NCAA Division I athletes.
NCT06565468 · Prospective Cohort Crossover Study
Assessed the impact of cold water immersion (CWI) on objective and subjective recovery metrics in NCAA Division I athletes, using continuous WHOOP biometric monitoring to identify individual responders.
Investigating how targeted interventions affect deep sleep, REM sleep, and sleep consistency in athletes using continuous wearable monitoring.
Studying cold-water immersion, supplementation, and other recovery modalities to develop personalized protocols based on individual physiological responses.
Leveraging WHOOP data—HRV, resting heart rate, respiratory rate—to identify individual responders and predict recovery trajectories.
Measuring reaction time, skill execution under cognitive load, and decision-making to understand the brain-body connection in athletic performance.
Rigorous, placebo-controlled testing of supplements including magnesium L-threonate and creatine to establish evidence-based recommendations for athletes.
Developing frameworks for using biometric data to guide training load, inform return-to-play decisions, and reduce injury risk across collegiate sports.
Our team combines clinical sports medicine expertise with research methodology across two leading academic medical centers.
