The accuracy of the heart rate monitor on the Redmi Watch 5 Active, like many wearable devices, can be influenced by several factors, including fitness levels and age. However, specific studies or detailed reviews focusing on these variables for the Redmi Watch 5 Active are limited.
General Accuracy of Heart Rate Monitoring
The Redmi Watch 5 Active is equipped with a heart rate sensor that provides continuous monitoring. In general, the heart rate tracking is considered to be fairly accurate, especially during resting conditions or light activities. For instance, when compared to other devices like the OnePlus Watch 2R, the Redmi Watch 5 Active showed similar heart rate readings during prolonged workout sessions[1]. Additionally, a review noted that the heart rate monitoring was "very similar" to that of other smartwatches during such sessions[1].
Variability with Fitness Levels
While there isn't specific data on how the Redmi Watch 5 Active's heart rate accuracy varies with different fitness levels, it's known that wearable devices using photoplethysmography (PPG) technology, like the Redmi Watch series, can be less accurate during intense exercise. This is because PPG measures changes in skin perfusion, which can be affected by factors such as movement and blood flow changes during exercise[3]. Therefore, it's plausible that the accuracy might decrease during high-intensity workouts, regardless of fitness level.
Variability with Age
Age can also influence the accuracy of heart rate monitoring due to changes in skin thickness and blood flow. Older individuals might experience less accurate readings due to these physiological changes. However, there is no specific data available for the Redmi Watch 5 Active regarding age-related accuracy variations.
Comparison with Other Models
The Redmi Watch 5 Lite, another model in the series, has been noted for its accurate heart rate tracking, particularly at rest. A comparison with the Apple Watch Series 10 showed similar resting heart rate accuracy, though it was noted that differences might occur during exercise[7]. This suggests that while the Redmi watches perform well at rest, their accuracy might vary during more intense activities.
In summary, while the Redmi Watch 5 Active provides generally accurate heart rate monitoring, its performance might be influenced by factors such as exercise intensity and physiological changes associated with age. However, specific studies or detailed reviews focusing on these aspects for this particular model are limited.
