Daniel Alexander van Skye, DBA is a leading expert in Applied Tennis Physiology, specializing in data-driven methodologies to optimize adaptation, recovery, and resilience in elite professional tennis. With over two decades of experience in human performance optimization, including operational work with Special Operations Forces, Daniel now works exclusively in professional women’s tennis .

Certified in Neurobiology, Sports Performance Psychology, and Workload Management by FC Barcelona Universitas, he applies high-resolution physiological monitoring using Firstbeat Technologies and Kubios HRV Scientific to deliver individualized performance profiling, autonomic nervous system diagnostics, and recovery modeling.

Daniel collaborates closely with WTA Tour athletes and their coaching teams, providing precise physiological insights to guide training intensity, taper protocols, and recovery timing. His work is structured around continuous monitoring, HRV-based readiness modeling, and menstrual-phase aware planning through the proprietary systems PhysioState and CycleShadow.

He has supported numerous WTA players in achieving breakthrough performances by applying a rigorous, biologically specific framework that ensures every intervention is targeted, aligned, and performance-effective.

Daniel’s work redefines how elite female tennis athletes train, adapt, and recover by bridging the gap between real-time internal physiology and sustained high-level output through intelligent, precision-based data application.
