Garmin has acquired Moxy Monitor, a company specializing in wearable near-infrared spectroscopy sensors that track muscle oxygen saturation. The deal follows Garmin's recent trademark application for a Muscle Battery feature designed to monitor athlete fatigue.
Why it matters
The acquisition allows Garmin to integrate specialized muscle-oxygen tracking technology directly into its ecosystem of watches and training computers. By leveraging Moxy Monitors hardware, the company aims to provide more granular metrics on hemoglobin and myoglobin levels during high-intensity exercise.
The Moxy Monitor device utilizes near-infrared spectroscopy to measure oxygenated hemoglobin and myoglobin in active muscle tissue. While Moxy Monitor devices currently pair with various training platforms, the exact integration timeline for Garmin devices is unknown.
The players
Garmin
Garmin is a multinational technology company that produces GPS, wearable fitness trackers, and navigation equipment for the automotive, aviation, and sports industries.
Moxy Monitor
Moxy Monitor is a specialized hardware manufacturer that develops wearable sensors used by athletes and researchers to monitor oxygen levels in active muscle tissue.
The details
Moxy Monitor technology allows users to track real-time muscle oxygen saturation, providing data that helps athletes manage training loads and recovery. Garmin appears to be preparing to incorporate these metrics into its existing software suite through a proprietary feature known as Muscle Battery.
Timeline
Garmin filed a trademark application for Muscle Battery in 2026.
Garmin officially confirmed the acquisition of Moxy Monitor on September 29, 2026.
The Big Picture
The development of a Muscle Battery feature follows the industry-standard success of Garmin's Body Battery energy monitoring feature. This acquisition represents a strategic pivot toward deepening physiological diagnostics within the competitive wearable technology sector.
Athletes and fitness enthusiasts may soon see more detailed muscle fatigue analysis integrated directly into their Garmin watch interface. This development could eliminate the need for secondary, specialized hardware during training sessions by consolidating data in one app.
The takeaway
Advanced muscle oxygen tracking, once reserved for specialized researchers, is becoming increasingly accessible to mainstream users. Athletes should keep an eye on future software updates to see how these new metrics can be used to optimize recovery periods.
