Garmin fans could soon get ‘muscle oxygen’ readings in future devices

Garmin may be on the brink of expanding its wearable lineup with muscle‑oxygen (SmO₂) monitoring, a capability currently limited to specialist gear used by elite athletes. The rumor stems from a report by the5krunner that cites a source with direct knowledge of a quiet purchase of Moxy Monitor, a firm that supplies near‑infrared spectroscopy sensors for SmO₂ readings. If true, the move would reshape how serious athletes track physiological performance and could pressure rivals to accelerate similar offerings.

Strategic Fit of Moxy Monitor Within Garmin’s Portfolio

The acquisition would give Garmin immediate access to a technology stack that it has only hinted at through a patent filed earlier this year for an SmO₂ algorithm. By absorbing Moxy Monitor, Garmin could bypass years of R&D and embed a proven sensor suite into its existing ecosystem of GPS, heart‑rate, and VO₂ max metrics. This aligns with Garmin’s broader strategy of catering to high‑performance users who demand granular data beyond basic activity tracking.

From a market perspective, the addition of SmO₂ could differentiate Garmin’s premium devices from competitors that still rely on indirect proxies for muscle fatigue. The report notes that Moxy Monitor’s founder responded to inquiries by directing questions toward Garmin rather than his own press office, an implicit acknowledgment that the deal is moving forward. Such a signal suggests Garmin is positioning itself to dominate the niche of data‑driven endurance training.

Technical Hurdles of Integrating Near‑Infrared Spectroscopy

SmO₂ measurement requires a near‑infrared spectroscopy sensor that cannot be miniaturized to a typical wrist‑worn form factor. The5krunner explains that “new hardware would be required if Garmin were to put Moxy Monitor’s tech to good use,” meaning a dedicated strap or chest‑mounted module is likely. This hardware demand raises questions about battery life, form‑factor ergonomics, and the cost premium that end users would bear.

Garmin’s existing sensor suite already includes optical heart‑rate and pulse‑oximeters, but those operate at different wavelengths and with distinct signal‑processing pipelines. Integrating an SmO₂ sensor would necessitate redesigning the firmware stack to handle the additional data stream and to fuse it meaningfully with existing metrics. The engineering effort could delay rollout, but the payoff would be a richer physiological profile that informs training load and recovery more precisely.

Competitive Landscape and Market Implications

Garmin is not the only player eyeing SmO₂. The report highlights that competitor Whoop has patented its own SmO₂ strap, indicating a broader industry shift toward muscle‑oxygen analytics. By securing Moxy Monitor’s technology, Garmin could pre‑empt Whoop’s move and claim first‑mover advantage in the mainstream wearable segment. However, Whoop’s focus on subscription‑based analytics could still attract users who prefer a cloud‑centric model.

The entry of SmO₂ into consumer wearables also raises the bar for data privacy, as muscle‑oxygen levels can reveal fatigue patterns and training intensity that are highly personal. While the article does not discuss privacy policies, the integration of such granular biometrics will likely prompt regulators and users to scrutinize data handling practices more closely.

What This Actually Means For You

  1. SmO₂ data could become a new performance metric on future Garmin devices, offering insight into muscle oxygen saturation alongside heart‑rate and VO₂ max.
  2. Expect a separate sensor module or strap, as current wrist‑worn designs cannot capture near‑infrared spectroscopy signals.
  3. Garmin’s move may accelerate pricing competition, potentially lowering the cost barrier for advanced physiological monitoring.
  4. Enhanced data granularity could improve training plans, but it also means more personal health data will be stored on the device and in Garmin’s cloud.
  5. Watch for official announcements; Garmin has not yet commented, so timelines remain speculative.

Immediate Action Steps

Monitor Garmin’s official channels for a press release confirming the acquisition, as well as any firmware update notes that mention SmO₂ support. If you are an athlete relying on precise training data, consider evaluating current Moxy Monitor offerings to understand the baseline capabilities before Garmin potentially integrates them.

Simultaneously, review Garmin’s privacy policy to ensure you are comfortable with how additional biometric data might be collected, stored, and shared. Adjust data‑sharing settings now to pre‑empt any future changes that could arise from the new sensor integration.

Frequently Asked Questions

Will Garmin add muscle oxygen sensor to future watches?

The rumor, sourced from the5krunner, suggests Garmin has quietly acquired Moxy Monitor, a firm that makes SmO₂ sensors, and filed a patent for an SmO₂ algorithm earlier this year, indicating a likely path toward integration.

How does SmO₂ measurement differ from heart‑rate monitoring?

SmO₂ uses near‑infrared spectroscopy to assess the oxygen saturation of muscle tissue, whereas heart‑rate monitoring tracks cardiovascular activity via optical or electrical signals; the former requires a dedicated sensor that cannot be placed on a standard wristband.

What hardware is needed for SmO₂ on a wearable?

According to the report, “new hardware would be required” because SmO₂ readings need a near‑infrared spectroscopy sensor, meaning Garmin would likely introduce a strap or chest‑mounted module rather than a wrist‑only device.

What Do You Think?

Will the addition of muscle‑oxygen monitoring give Garmin a decisive edge, or will the required hardware complexity limit its appeal to only the most serious athletes?
