The Human Exersome Initiative (HEI): Rationale, study design, and protocol

Area of Science:

• Exercise physiology
• Biochemistry
• Human biology

Background:

• Physical activity and exercise (PA/EX) offer significant health benefits.
• While adaptations to PA/EX are known, the effect of varying "exercise dose" on human biochemistry is understudied.
• Previous research often used non-standardized exercise protocols or specific populations.

Purpose of the Study:

• To address the knowledge gap regarding the impact of "exercise dose" on human biochemistry.
• To comprehensively define how exercise intensity and duration affect blood-based biochemistry.
• To establish a foundation for understanding exercise response variability due to factors like age and health status.

Main Methods:

• The Human Exersome Initiative (HEI) employs controlled laboratory-based acute exercise testing.
• Comprehensive systemic biochemical profiling is utilized to analyze blood samples.
• Focus on isolating the effects of PA/EX duration and intensity in healthy young adults.

Main Results:

• The initial phase of HEI focuses on defining the impact of "exercise dose" on blood biochemistry.
• Data will be collected from healthy young men and women to establish baseline responses.
• Future research will incorporate data from diverse populations to explore variability.

Conclusions:

• This research aims to elucidate how the human exercise response varies with phenotypic variability.
• Anticipated outcomes include biomarker discovery and understanding molecular pathways of metabolic response.
• Findings will inform the identification of optimal exercise doses for clinical interventions and personalized health strategies.
