EP64 Garmin Muscle Battery and More CIRQA Leaks (ft. AI Insights)
The Deep Dive Podcast: Sports Tech & Performance for Endurance AthletesShow Notes
Garmin CIRQA & Muscle Battery: SMO2 Revolution (ft. AI Insights)Garmin is building CIRQA, Muscle Battery & NIRS hardware to track local muscle oxygen — and it could rewrite how we all train.
Two trademark filings. A leaked internal survey. A deliberate API lockout. These are not isolated rumours — they are pieces of a single, cohesive strategy. In this episode, we connect the dots on what Garmin is quietly building: a fully integrated, vertically controlled strength and recovery ecosystem built around localised muscle oxygen saturation (SMO2).
Key questions we dig into:
• What are CIRQA and Muscle Battery — and what do the trademarks actually tell us? • Why can SMO2 never be measured from the wrist, and what hardware does Garmin need to build? • How does Muscle Battery do for muscles what Body Battery did for HRV? • Why is Garmin locking third-party developers out of its strength API — and who gets hurt? • Can Garmin make NIRS data consumer-friendly, or is this just expensive noise for data nerds? • What does this mean for WHOOP, Moxie, Train.red — and the fragmented SMO2 market?
Verdict: This is not incremental product development. If Garmin executes, CIRQA and Muscle Battery represent a genuine paradigm shift — from systemic cardiovascular metrics to localised, objective muscular readiness. The technical hurdles are real, but the strategic intent is unmistakable.

Garmin CIRQA at $199.99: Whoop annoyer or genuine rival? THE5KRUNNER unpacks the launch day reality.
Your smartwatch recovery algorithm thinks you're a 25-year-old man. How wearables fail female physiology, VO2 max and HRV. The interpretation layer inside Garmin, WHOOP and Oura was built on male physiology. The sensors gather accurate raw data, but the algorithms treat the menstrual cycle, pregnancy and menopause as noise. We break down why your luteal phase reads as overtraining, why VO2 max estimates penalise the fittest women, how skin tone and wrist size degrade optical heart rate, and the clinical danger of missing RED-S behind a "normal" recovery score. Key Questions We Answer: • Why does a 28-day hormonal cycle break training software built on a 7-day calendar week? • How does progesterone's thermogenic effect crater your body battery and HRV during the luteal phase? • Why do Garmin algorithms underestimate VO2 max for women and overestimate it for men? • Why does the Forerunner 245 penalise highly trained female athletes by 6.3 ml/kg/min? • How do melanin and small wrist anatomy compromise optical heart rate accuracy? • What early RED-S warning signs can wearables flag weeks before injury? • Why does a regular monthly bleed not confirm hormonal health? The Verdict: Wearable data is useful to female athletes only as a personalised baseline, never as objective diagnostic truth. The fittest your data looks, the day of ovulation, is the day ligament laxity peaks and ACL risk is highest. Force clean inputs with a chest strap, set your true maximum heart rate manually, and contextualise every readiness score against cycle phase, training load and life stage. The athlete has to become the final algorithm.
