The Data Science Behind HRV w/Dr. Marco Altini - a podcast by Jason Moore: Systems Designer, Tinkerer, Health and Performance Consultant

Data analysis and statistics can be confusing or time consuming - especially HRV, health, or performance data.

Dr. Marco Altini joins us to share some of the nitty gritty of how Data Science plays a role in Heart Rate Variability analysis and other types of quantifiable research and self experimentation.

Marco is the lead data scientist at Bloom which is a pregnancy wearable technology company and he is the founder of HRV4Training - more details on his extensive background in wearable tech in the episode.
