Garmin Vivosmart 4 & Tracking Parameters

Apart from tracking heart rate, daily steps, and calorie expenditure – Vivosmart 4 has extra features that will help you even control your stress levels or plan the intensity of your fitness routine.

Let’s have a closer look at it.

Blood’s oxygen level measurement

The Pulse Ox sensor on Vivosmart 4 can estimate your body’s blood oxygen saturation level. Those measurements depend on a few factors, including the lungs’ capacity and abilities of your metabolism.

With Vivoactive 4, you can track how much oxygen is in your body while sleeping or during the training.

Advanced Sleep Monitoring

We all know how sleep is essential to your well-being. 

Vivoactive 4 can offer quite a complete package when it comes down to tracking your sleeping hours.

Apart from checking up on your SEM & REM stages, Garmin also tracks how well you breath and how much oxygen is delivered to your body overnight.

It can be super helpful to see whether the quality of your sleep is good or bad.

Optimization of the energy

Vivosmart 4 can combine all data like stress levels, heart rate, activity, oxygen saturation, and sleep into one algorithm to optimize your energy.

In simple words, this tracker can advise you whether you should exercise or not because your body is tired.

It makes sense when it comes down to planning the intensity of your workout throughout the week

Wise choices can help you not only avoid overtraining or chronic fatigue but increase your performance over time.

It’s not about training HARD. It’s about training SMART.

What Customers Say About Garmin Vivosmart 4

The band on the Garmin is a bit unique as fitness trackers go. Stretchy unibody construction. Some have reviewed the band did not last long but I have no issues other then starting to see the band starting to get smoothed.

satisfied customer

I really enjoy the band can make it tighter then most and stay comfortable no constant shaking of the wrist to move the watch forward or back your wrist.

happy customer

The heart rate sensor is usually accurate when you turn on activity recording but in normal mode usually gives me no higher then 70 when I’m at 130-180 I’m guessing it’s for battery saving that they lower the flashes/reading of the sensor, making the resolution of BPM very low but in the range of normal adult heart rates.
